What is the best resolution for a tablet. Types of matrices and manufacturing technologies


May 30, 2016

In this article, tips to help you choose a tablet.

First, what is a tablet?

This is a large, or even very large, smartphone - which is inconvenient or impossible to make calls at all. The filling is the same as in smartphones. The operating system is most often the same - Android. So yes, it's a big, heavy smartphone.

The question arises, why then do we need tablets? If there are smartphones.

Tablets have three advantages over smartphones:

  • Larger screen. On a tablet screen or higher resolution or, at the same resolution, image details are larger, which is important for people with not very good eyesight.
  • On a larger screen, it is more convenient to use the touchscreen.
  • Usually tablets have a larger battery. And this gives a lot of autonomy.

What are tablets for?

The tablet allows, more conveniently than on a smartphone, to perform the following actions:

  • Read or edit some text.
  • View site.
  • View mail and reply to emails.
  • Write a message to social networks, forum, chat.
  • Easy to process a photo or other image.
  • Play easy games.
  • Watch a video or movie.

A tablet is not a replacement for a computer.

Although a tablet is a computer, at its core, it cannot completely replace a computer. On a tablet, you can't:

  • Fully work with documents - test files, spreadsheets, etc.
  • Fully work with graphics.

Because:

  • Small screen.
  • Lack of keyboard and mouse. Although you can connect external USB or a Bluetooth keyboard and mouse, but you won’t carry them with you.
  • The Android (or iOS) operating system for which there are no professional applications of the MS Office or LibreOffice level.
  • The operating system Android (or iOS) under which there is no full support for the network and external equipment (printers, etc.).

True, there are tablets on the hardware Intel platform, with installed Windows 8 or 10. But they are:

  • Expensive.
  • Bigger and heavier.

That is, in terms of their weight and size characteristics, these are not exactly tablets, and thus they are inferior to Android tablets in mobility.

And they have the same limitations. small screen, the lack of a full keyboard.

The main function of the tablet

If you approach the issue pragmatically, then main function tablet is to ensure the use of the Internet in more convenient form than is possible on a smartphone.

The main characteristics of tablets

Tablet manufacturer. The best tablets are sold by companies Sony, Asus, Samsung, Lenovo, Acer. Although there are lesser known Chinese companies who make good tablets and are much cheaper than this five. Nevertheless, buying a tablet of one of these five is a very high probability that the tablet will serve you for a long time and will not torment you with problems. While buying a Chinese tablet is a lottery.

Tablet dimensions. The right tablet should fit in an ordinary men's or women's bag. That is, about the size of a thin hardback book. A 10 inch tablet can only be put in a large bag. A 7 or 8 inch tablet can even be put in a large pocket of clothes or in any bag.

Tablet weight. The correct tablet should have a weight of no more than 500-600 grams. A 10 inch tablet usually weighs 600-700 grams. A 7 or 8 inch tablet usually weighs 300 - 400 grams.

Tablet autonomy(battery life). A good tablet should run on batteries for at least 6-8 hours. To a greater extent, this indicator depends on the battery capacity, which is indicated in milliamp-hours. For example 4000 mAh (or 4000 mAh).

GSM 3G (or 4G LTE) module ( cellular) . The tablet is needed mainly so that anywhere you can get relatively convenient access to Internet resources. WiFi adapters is in all tablets, but in our country there are far from everywhere points WiFi access. This means that in order to have Internet access anywhere, you need an internal GSM module in the tablet.

However, if the tablet supports the USB-host operating mode (otherwise it is also called USB OTG), then an external USB cellular modem can be connected to the tablet. However, this possibility must be clarified for each specific model. Yes, and it's inconvenient - a modem dangling outside.

Screen brightness. The idea of ​​a tablet suggests frequent use outdoors, in natural light. In the summer it can be very bright outside (in sunny weather). And many liquid crystal displays become almost indistinguishable in sunny weather.

screen matrix. Tablet screens use two types of matrices:

  • TFT TN- very cheap matrices. There are problems with viewing angles and color reproduction. At viewing angles less than 90%, color distortion occurs. At viewing angles closer to 180 degrees, the picture can become almost indistinguishable.
  • TFT IPS- more expensive matrix. Viewing angles are close to the maximum 180 degrees. Wider color gamut.

Secondary tablet options

Characteristics of tablets that only improve the consumer quality of tablets, but are not critical:

Tablet connectors. A good tablet should have a USB connector operating in Host mode (otherwise it is also called USB OTG). This will allow you to connect a USB flash drive, keyboard, external drive or an external cellular modem. It is very good if there is also an HDMI connector, this will allow you to connect the tablet to a TV or monitor.

Physical screen size(diagonal in inches). How smaller size screen, the smaller the tablet, but also the smaller the image on the screen. The three most common screen sizes are 10.8 inches (4:3 or 16:10 screen) and 7 inches (16:10 screen).

Tablet screen resolution(in dots horizontally and vertically). A good tablet should have a horizontal resolution of at least 1024 dots (pixels). The most common tablet screen resolutions are 1024 x 768 and 1280 x 800 pixels.

But in the mid-price segment there are models with a resolution of 1920x1080, 1920x1200, and in the segment of expensive models even 2048x1536 (the so-called Retina display). Usually the resolution is higher than 1280 x 800 pixels for models with a screen diagonal of 9 or 10 inches. But there are also rare models with a diagonal of 8 inches and a resolution of 2048x1536 pixels.

The higher the screen resolution, the prettier picture. However, the more expensive the screen and the tablet itself. Despite the fact that there is no objective need for such a high resolution yet. Most of the resources - websites, videos - fit into the FULL HD resolution of 1920x1080 at most. For books and documents, even a modest 1024 x 768 is enough. And so it turns out that a high resolution, 1920x1080 and above, today only wins when viewing photos.

RAM. A good tablet should have at least 512 megabytes of RAM. But it is better if 1 gigabyte. For an Intel x86 Windows tablet, it must be at least 2 gigabytes.

Built-in memory. The built-in memory of tablets is the same in meaning as a disk in a computer. And technically this SSD drive in frameless design (soldered directly to the board). In this very built-in memory is installed operating system tablets and applications. The same built-in memory stores user data (files) and the application cache.

Usually in tablets it is possible to expand this memory by installing an SD card. For Android tablets, the minimum internal memory is perhaps 8 gigabytes. Although Android can be installed on 4 gigabytes, there will already be too little space for programs and user data.

Tablet selection

The first question you should ask yourself is - do you really need a tablet? After all, there are alternatives:

  • You can buy a smartphone, it will be smaller, lighter.
  • You can buy a laptop, it will be possible to work normally on it.

And when choosing a tablet, the main thing is to determine exactly what you want.

If it's a matter of status, then buy Apple or Samsung.

If you really need it for those tasks that you can really solve with it, then you can buy any good tablet.

If you have to carry it around a lot, then maybe it makes sense to buy a 7 or 8 inch tablet. And the size is smaller and weight.

If you want to work more conveniently with texts on a tablet, then you can buy a so-called transformer tablet (sometimes they are called a laptop-tablet). For example ASUS Transformer Pad. These tablets have a docking station similar to the bottom half of a laptop. This docking station has a keyboard and additional connectors. The tablet is inserted into such a dock and something close to a laptop is obtained. There is another variation on the same theme - an external keyboard, but it is made in the form of a tablet case. This option is certainly more convenient than the docking station.

But if the tablet has a USB connector operating in Host mode, then you can do without a docking station, but simply connect it to USB keyboard and mouse. But this can be done at home or at work, it is inconvenient to carry a mouse and keyboard with you. And besides, such external devices will drain the battery of the tablet more.

However, you need to understand that in this case, full-fledged work will also be impossible - after all, tablets are usually made on the ARM architecture and the operating systems of these tablets, Android, Windows RT, iOS do not have such functionality and such a set of programs as Windows or Linux.

If you really need a tablet computer, then you need to look for a model that is made on Intel architecture x86 (often incorrectly referred to as a Windows tablet). For example Microsoft Surface Professional (not to be confused with Microsoft Surface RT). These are really computers on which you can install a full-fledged OS - Windows or Linux. However, the size and weight of these tablets will be larger than for ARM tablets. For example Microsoft Surface Professional weighs a kilogram.

My advice for choosing a tablet is simple. It contains several items:

  • Screen diagonal 8 or 7 inches.
  • Screen matrix type - TFT IPS. Not to be confused with TFT TN - it's worse!
  • Screen resolution - for 8 inch tablets 1024 x 768, 1280 x 800 pixels, and for 7 inch 1280 x 800 pixels.
  • RAM - not less than 1 gigabyte.
  • Internal memory (for installing programs and writing data) not less than 8 GB.
  • Support removable cards memory. Usually this microSD/microSDHC.
  • Mode-enabled USB connector Host (OTG).
  • HDMI connector. But it is very rare on 7 and 8 inch tablets.
  • Interior GSM module, 3G or LTE.
  • Weight no more 400 grams.
  • Battery capacity not less than 4000 mAh.

8 inch screens mean not only 8 inches, but also 7.85 and 7.9 inches. Strictly speaking, this "8" form factor, historically, means a diagonal equal to 7.85 inches and a 4:3 format - this is exactly the screen size that the first tablet of this form factor had - Apple iPad mini. But today there are many models with an 8-inch widescreen, with a resolution of 1280 x 800.

The presence of USB host (OTG) and HDMI will allow you to make almost a computer out of the tablet - connect a keyboard and mouse to the tablet, and the tablet to a monitor (or TV) and thus work almost like on a computer, except for the restrictions imposed by the Android OS.

Size 8 or 7 inches will allow you to carry the tablet in any bag. 7 inch can even be in a jacket or coat pocket.

Weight 300 - 400 grams will allow you to easily hold the tablet in your hands and even in one hand.

You can even make calls from an 8-7 inch tablet. Not very convenient, but real.

The battery capacity of 4000 - 5000 mAh will allow you to use the tablet for 6-8 hours without recharging. It implies 6-8 hours of pure work with the tablet, without waiting periods.

If there is no internal GSM module, but there is a USB host, then you can connect an external cellular modem. True, it will "hang out" outside, but the Internet will be. However, not all USB host tablets support USB cellular modems- needs to be clarified!

Chinese batteries

When buying Chinese tablets, you need to be prepared for the fact that after 2-3 years you will have to change the battery. The difficulty is that, unlike phones, in a tablet, the battery cannot simply be pulled out and replaced with another one. It is necessary to remove the cover with the help of tools, solder the old one and solder the new one. That is, you will have to contact the workshop and you will pay not only for the battery, but also for the work.

In this case, Chinese tablets mean all inexpensive tablets, regardless of manufacturer. At the same time, more expensive Chinese ones, such as Asus, will certainly live longer.

Cheap Chinese tablets

Tablets under $100 are considered. Sold as directly in China, under native labels. So we have in Russia "killed" under the "Russian" labels such as Irbis, Prestigio, Digma Qumo.

On the one hand, these are disposable devices for a couple of years. They are unlikely to last longer. On the other hand, in a couple of years it will be possible to buy a new Chinese tablet, but with something fresh inside, for example new version Android. or screen higher resolution. Or with higher resolution cameras.

The difficult question is whether to buy such tablets. On the one hand, fragility and buggy, on the other hand, the price is two to three times lower than on Asus, Samsung, Sony. Whatever you say, low price very strong factor.

I would say this - you can definitely buy cheap tablets. But the consequences must be carefully weighed. And be prepared for these consequences.

Tablet market in 2016

4:3 format tablets, the so-called iPad format, have almost disappeared from sale. iPad mini. Now tablets with a diagonal of 8 "are already widescreen, with a resolution of 1280 x 800.

In connection with the rise in the dollar, a bunch of models costing less than $100 appeared.

What are they saving on?

  • At least on internal memory, almost all cheap tablets now come with 8 GB. For such a tablet, you will almost certainly have to buy an SD card.
  • The batteries are probably even worse.
  • No aluminum cases. Black plastic.
  • Screens with a resolution of 1024 x 600 were taken from the dustbin of history.

In general, the picture of 2016 is as follows - the market is trying to survive at the expense of dull shit.

Here are some interesting models that are on sale in 2016:

  • Prestigio MultiPad Wize 3108- very cheap. Battery 4200 mAh Intel processor.
  • IRBIS TX89 LTE- very cheap. There is LTE.
  • Huawei MediaPad T1 8.0 8 GB - battery 4800 mAh
  • ASUS ZenPad 8.0 Z380KL - 16 GB, There is LTE.
  • Samsung GALAXY Tab A- PLS Matrix. iPad Format mini (4:3 1024 x 768). 16 GB LTE. Samsung, I don’t know how it is now, but a few years ago Samsung was distinguished by high reliability and durability mobile technology, including long-life batteries. But the price is Samsung.

The federal network of stores Yulmart is a good place to buy computer and household appliances. Low prices, convenient purchase process.

Choosing a tablet computer is not an easy task. Especially now, when the market is simply crowded with the most different models in various price categories. I want to save and buy quality model which is convenient to use.

The main element that everyone pays attention to is the screen. It performs both the function of information output and its input. For this reason, for maximum convenient use It is required that the screen be large and of high quality.

However big screen entails, firstly, a higher price, and secondly, some inconvenience. A tablet with a very large screen cannot be put in your pocket, and it will be inconvenient to hold it with one hand. So what to look for when choosing?

Before viewing the tablet with the best screen, you definitely need to know what kind of screens there are. A lot depends on this indicator. So, tablets use three types.

Resistive

The simplest and cheapest. They also have a number of positive properties in the form of unpretentiousness to the object being controlled (finger, stylus, etc.), resistance to pollutants, and very low cost.

Despite these obvious advantages, resistive touch screens have big drawbacks. The most important and significant of them is the probability of rapid wear of the surface due to pressing. Usually, resistive screens serve no more than six months. It is for this reason that most manufacturers do not put them on their devices.

Projected-capacitive

Can withstand very well mechanical impact, respond well to touch. Despite the versatility, this type has some sensor error, and its cost is higher.

capacitive

They can be called the most reliable and popular. All well-known manufacturers install such displays on their devices. These screens are bright, durable and quite cheap. They react to special devices input and finger. If a glove is worn, there will be no reaction.

The tablet with the best screen will naturally have a capacitive I/O device. I must say that this type of display has a lot of varieties, but we will highlight a few of the most popular.

Types of capacitive screens

Capacitive matrices can have the following types:

  • IPS (cheapest and most popular);
  • PLS (similar to IPS, but used exclusively by Samsung);
  • AMOLED (does not require backlighting and a very bright matrix, but the eyes get tired of it);
  • Super Clear LCD (touch analog LCD-monitors).

The reaction of the screen and its quality do not depend too much on the type of matrix. But the image shows that ordinary cheap IPS displays fade in the sun, but AMOLED and LCD do not.


The tablet with the best screen will naturally have a capacitive I/O device.

best tablet screen

Highly important indicators when determining screen quality are:

  • permission;
  • frequency;
  • image quality;
  • the size.

Let's consider what is the tablet with the best screen, and make a comparison in the form of TOP-6, gradually approaching the leader.

№ 6

So last on the list is a tablet. Asus Memo Pad HD 7. Although this gadget has a rather small (seven-inch) screen with a modest resolution of 1280 × 800 pixels, it is very bright and colorful. Implementation colors here on top. The image, which is easy to view on the screen, is quite detailed and rich in color. With this tablet in the form of pre-installed software comes a special one, which makes it possible to easily adjust all display settings and make it exactly the way you want.


№ 5

In fifth place is a gadget called Amazon Kindle Fire HDX7. In our country, this tablet is not very popular, but in the world markets it is among the twenty best-selling. The Amazon model offers users a very high-quality seven-inch display with good resolution in 1920 at 1200 points. It is this screen that is installed in Google's Nexus in 2013.

The image of the device is very clear, colorful and detailed. But at the same time, the cost of Kindle Fire is lower than its competitors. Sensor feedback is good even in severe frosts. Also, thanks to a special matrix, it is convenient to work on this tablet in any light.


№ 4

The fourth place is occupied by the famous samsung galaxy Tab 3 8.0. There probably won't be one modern man who would not have heard of this line of tablets. But the eight-inch model has become a legend precisely because of its colorful screen. It was appreciated even by the most demanding people who prefer to buy an expensive but high-quality tablet. The display resolution is not the highest that the market can offer, but this does not prevent this gadget from producing bright and clear pictures.


№ 3

Bronze medalist for this moment is the brainchild Google called Nexus 7. This tablet was released in 2013 and immediately became one of the most desired devices for progressive youth. The screen resolution of this device is 1920 by 1200 pixels. But at the same time, their concentration per square inch is quite dense, since the diagonal of the display is only seven inches. Bright and contrasting, this one will interest anyone.


№ 2

The silver medalist is the second brainchild from Google - Nexus 10 Tablet. Why did he take second place? Just such a gadget with a huge, bright, colorful and clear screen cannot be ignored. The sensor has good responsiveness, and all applications and games literally “fly” thanks to powerful processor and large RAM.


A gadget with a huge, bright, colorful and clear screen cannot be ignored

№ 1

Gold in our TOP-6 goes to the only device that does not run Android. It is, you guessed it, Apple iPad on iOS. Like it or not, the championship laurels always go to an experienced manufacturer who has proven himself well, producing high-quality products for many years.

The iPad screen has the highest resolution - 2048 by 1536 pixels. And this is with a ten-inch diagonal. This display can truly be considered the best in the world. But, as always happens, you need to pay very well for convenience and high quality. For this reason, such a gadget will not be affordable for everyone.


This display can truly be considered the best in the world.

New with the best screens

  1. The device called Jola Tablet was presented to the public recently. It is planned to go on sale in the first half of 2015. The difference is its own OS called Sailfish. In addition, the gadget has a seven-inch screen with a resolution of 1536 × 2048 pixels. It implements IPS LCD matrix technology with support for 5 points at the same time. This toy will cost users about $200.
  2. The second gadget good display, which recently appeared on the shelves, is Dell Venue 8 7000. Its colorful, bright and sun-fading OLED screen has a diagonal of 8.4 inches and a resolution of 1600 × 2560 pixels. In addition to the display, the gadget has another distinguishing characteristic in the form of a case thickness - only 6 mm.
  3. Another novelty is Galaxy Tab S with a screen size of 8.4 inches. This "monster" has at its disposal eight cores, three GB of RAM and a gorgeous screen with Super AMOLED matrix. The technology allows you to support up to ten points simultaneously, there is a fingerprint scanner and much more. If you want to get super modern, almost perfect colorful, fast tablet, and at the same time there is a desire to preserve your eyesight, then this gadget is just for you. Naturally, for such a "toy" you will need to pay a rather impressive amount - $ 400, which is relatively expensive. But in return, you can get a device that has ideal parameters.

So, when choosing a tablet with the best screen, you need to pay attention not only to the number of dots (resolution), but also to the brightness of the screen, as well as the possibility of making individual settings. If working and playing with a gadget takes a lot of time, you need to take care of your eyes. Tablets with high-quality capacitive screens will help with this.

Hello, readers of the site IT-lessons!

If you've been thinking about buying a tablet, then this updated Q&A article might be helpful to you.

So, today we will help Yanina figure out the choice of the diagonal and resolution of the tablet for reading scanned books in PDF format.

Question from Janina:

Good afternoon!
I downloaded e-books - scanned (by computer topics) in PDF format from the Internet.
There are tablets with a resolution of 800x480 and 800x1280. Which tablet will best image scanned e-books?
Thank you!

What is a tablet, we learned in. Today, as you already understood, we will talk about choosing a tablet for a specific purpose.

I would like to immediately clarify the following point: if you want to use the tablet only for reading books, then be sure to pay attention to e-books, they are more comfortable perceived by the human eye. A little more about this in this article.

A little about the PDF format

The PDF format was created for electronic versions documents

home PDF feature: On any computer (laptop, tablet, etc.), the document will look the same.

There are many books available in PDF format, but if you read a lot, then it is better to try to find books in other, more convenient formats(but more on this in one of the future IT lessons).

Scanned books in PDF format can be in two versions:

  • Recognized (text can be selected);
  • Unrecognized (in the form of a picture, the text cannot be selected).

When reading the first view, some programs may scale the font to make the text larger (often referred to as reformatting). The second view can only be enlarged as a whole, like a photograph.

Tablet screen size

In this case, the size of the tablet screen is more important - diagonal. If the size is less than 8 inches, it will be problematic to read scanned books in PDF format (text is too small).

Everyone's eyesight is different, so before buying check if the text is clearly visible to you, whether the eyes strain, whether it is necessary to increase the page of the book so much that it does not fit entirely on the screen (in this case, you will have to move it horizontally when reading).

An important point will be how you plan to use the tablet, carry it in your pocket or backpack (bag). If in your pocket, then you need to pay attention to 7-7.7 inch options. If the option is a backpack bag, then pay attention to 8-10 inches.

Tablet screen resolution

To account permissions. It affects the detail of the image, i.e. how small an object can be displayed on the screen. If the diagonal is large and the resolution is low, then you will see the division of the image into dots (called "pixelization").

You can find a wide range of resolutions:

  • 2560×1600
  • 2048×1536
  • 1920×1200
  • 1920×1080
  • 1366×768
  • 1280×800
  • 1280×768
  • 1024×768
  • 1024×600
  • 1024×480
  • 854×480
  • 800×600
  • 800×480

In this case, for the same diagonal, there can be different permissions. I'll give you a couple of examples.

Example:

Tablets with resolution 800×480 may have a diagonal 4 to 9 inches. It will be difficult to read books in PDF on a four-inch (either too small or large, but with constant movement to the right and left).

Another example:

Tablets with resolution 1280×800 may have a diagonal 7 to 13.3 inches.
Those. tablets from 7 to 9 inches can differ in the number of dots by almost three times. But for reading scanned books, high resolution will be redundant.

findings

First, decide how you will use the tablet (read at home, carry it in your jacket pocket, carry it with you in your bag), this will help you choose the diagonal.

When choosing a specific tablet computer model, you should pay attention to a number of parameters. One of the most important of them is undoubtedly the size and quality of the screen, because it is on the screen that you will view information, graphics and use it to control the operation of the device. So, what kind of screens do tablets have? They can be classified according to three criteria: screen size, resolution and performance technology.

Tablet screen sizes.

Modern gadgets can be divided into four groups on this basis:

The first - with a screen size of 5-6 inches diagonally. tablet computers belonging to this group are primarily distinguished by their compact size and a little more standard smartphones. Graphic picture displayed on this screen is different high definition, but small in size. The undoubted advantage of this group is a long time battery life devices, since the smaller the screen, the less power consumption will be.

The second group - tablets with a screen of 7-8 inches diagonally. These devices are also called "pocket" and it is generally accepted that given size screen makes working with the device the most comfortable and optimal. With such devices, you can easily watch movies, chat with friends in social networks, carry out Internet surfing and so on.

The third group - devices with a screen size of 9-10 inches. The dimensions of such a tablet at first glance may seem too large. It seems that these gadgets are inconvenient to use, but this is only the first impression. On the contrary, on a ten or eleven inch screen, you can watch movies in high quality, work with office programs and applications, surf the Internet.

And the fourth group - devices with a screen of 11.6-12.5 inches. These tablets provide maximum comfort during use, but are quite massive and large. It is already difficult to use them as mobile ones and they are most adapted for stationary operation.

Types of matrices and manufacturing technology.

The most common - IPS matrix . This technology was developed back in 1996 and has since reached its perfection. Screens made using this technology provide maximum image quality and color display.

A few years ago by Samsung Electronics introduced the first tablets to the market with pls matrix . This technology is different minimum time response, high level graphics quality.

Another technology used in modern gadgets - AMOLED. Benefits of this type screens are the ability to transmit the widest range of colors and low level energy consumption.

most new development modern tablet manufacturers is the technology Super Clear LCD. The main difference between screens using this technology- preservation High Quality image and contrast, regardless of lighting brightness and viewing angles. Simply put, with these tablets, you can comfortably work in the bright light of the Sun and view images at sharp angles.

Tablet screen resolution.

The value of this parameter directly depends on the screen size. For example, seven-inch screens are characterized by a resolution of 1024x768 pixels, eight-inch screens 1280x800 pixels, and so on.

The most optimal and comfortable for watching movies and working with programs and applications is considered to be a resolution of 1280x800 pixels. But this is for budget models.

At Apple tablets these figures are much higher and for eight-inch models can be 2048x1536 pixels.

As practice shows, tablet models with a screen size of seven or eight inches, capable of supporting a resolution of 1280x800 pixels and manufactured according to IPS technology or pls. Such devices provide maximum comfort at minimum cost and investment.

Choosing a tablet is no easier than choosing a smartphone. In the tablet market, the leaders are also 2 "giants", Samsung and Apple - while there are a lot of companies from Asia that do not claim the throne, but produce high-quality products worthy of the attention of buyers.

Which tablet to choose and what should you look at first of all? You will learn about this by reading this article to end.

The choice of a tablet must be approached somewhat differently than the choice of a smartphone - nevertheless, these 2 devices have different purposes. A smartphone is needed primarily for calls; The main function of the tablet is to provide the user with access to the Internet. Therefore, when choosing a tablet, you should prioritize those criteria that affect the convenience of Internet surfing - overall performance and display size.

Performance

The speed of the tablet depends on the chipset model, the number of cores, the clock speed, the graphics accelerator, the amount of RAM when searching for information on the network, watching movies and, in particular, the game process. An ordinary user who does not expect “miracles” from a tablet should purchase a device with the following minimum specifications performance:

  • Number of cores - from 4. 2 cores are now only enough for Apple tablets, which use processors of their own production. Buying a 2-core device with Android OS is worth it only in case of an acute shortage of money.
  • Clock frequency– from 1.4 GHz. You can watch movies and surf the Internet already at 600 MHz, but for resource-intensive games and applications this frequency will obviously not be enough.
  • The amount of RAM - from 2 GB. The buyer needs to remember that when starting the tablet established processes instantly occupy about 600 MB of "RAM". If the tablet has 1 GB of RAM, then only 400 MB remains for user processes - this is enough only to solve the simplest tasks.

For games, it is best to take a gadget with an NVIDIA Tegra processor line - for example, Asus Transformer Prime.

Display: size and resolution

Tablets are available in the following form factors: 7 inches, 8 inches and 10 inches. The device with a 7-inch screen has a compact size and can even fit in the lining of a jacket. It is convenient to use it as e-book, but for watching movies - not really.

A 10-inch tablet is more suitable for working with multimedia files. However, buying a budget gadget with a large screen is not recommended - for 2 reasons: First of all, such a tablet can be very bulky and heavy, Secondly, on the display of a cheap device, graininess will certainly be noticeable.

8-inch gadgets are not common. This is a borderline option, which in fact is devoid of the advantages of both of the above. It is worth refraining from buying an 8-inch gadget - especially since the accessories for such a form factor “weep a lot”.

As far as screen resolution is concerned, the best option for a 7-inch device it is HD (1280×720), for a 10-inch FullHD (1920×1080). Buy tablets with b about higher resolution is pointless: the user will not notice the difference in image quality, but will suffer from the fact that the gadget is quickly discharged.

If the tablet screen is made using OGS technology (that is, without an air gap), this extra bonus. OGS-screens are notable for their wide viewing angles and excellent color reproduction.

Availability of 3G

It will not be possible to put a SIM card into a tablet that does not support 3G - it will be possible to access the Internet from such a gadget only if there is a connection to WiFi networks. Usually, wifi tablet They are much cheaper than 3G counterparts. Therefore, for a buyer who intends to use the device mainly at home, it is more profitable to purchase a device without a SIM slot.

If you can put a SIM card in a tablet, this does not mean that you can make calls from it - iPad devices, for example, there is no call function. Does it support specific model tablet call function, you need to clarify immediately before buying.

Operating system

The following operating systems are installed on modern tablets:

  • iOS. The iOS operating system can only be found on gadgets manufactured by Apple. Its main advantages are stability and high speed work. The operating system is simplified as much as possible, and therefore does not require many processor cores and an impressive amount of RAM for correct operation. iOS users can download games and programs from the AppStore - in the summer of 2016, the number of applications in the store exceeded 2 million. Key disadvantage iOS is considered to be closed, due to which a novice user may have problems mastering the gadget.
  • Android. This operating system is open. Dealing with it is easy; data from a PC to an Android background can be thrown off without using additional software- like iTunes for iOS or Zune for Windows phone 7. Store android applications called Google Play. There are even more programs and games in it than in the AppStore, but not all of them can boast of decent quality; this is because only authorized Apple developers can place applications on the AppStore, and ordinary programmers on Google Play. Unlike iOS, Android is considered a vulnerable operating system and needs an antivirus.
  • Windows. Our site recently wrote that Windows Phone 8.1 was officially "dead" - the mobile operating system lost support from Microsoft. However good tablets with Windows 10 in 2017, there are a lot - gadgets based on Microsoft OS are produced by such large companies as Lenovo, Huawei, Asus. The advantages of the mobile “OS” Windows are considered to be a convenient “tiled” interface, a pre-installed package of full-fledged Office programs and undemanding to the hardware of the gadget. The key disadvantage is "poverty" official store Windows applications store. The last measurement, which took place in the fall of 2015, showed that there were only 669 thousand programs in the Windows Store - by that time there were already 1.5 million applications in the AppStore and Google Play.

Buyers who have experience of using Apple technology, you should prefer a gadget with iOS, it is better for beginners to take a device with a "green robot". A tablet with Windows 10 is still an option for an amateur; such a device can be advised to "burnt" geeks - to broaden their horizons.

Battery

The capacity of the battery depends on how long the tablet will last without recharging. This parameter should only be considered in conjunction with the performance and display characteristics of the device. A gadget with premium filling and a FullHD display, of course, will consume energy much faster than a budget model. For inexpensive gadget, against, big battery- too much luxury.

For those who are waiting for specifics, let's clarify: a gadget with a 7-inch screen will have enough batteries with a capacity of 3,500 - 4,000 mAh, a 10-inch tablet needs 5,000 - 7,000 mAh. Battery in 7 340 mAh tablet iPad Air 2 was enough for 10 hours of continuous Internet surfing.

cameras

It's naive to expect professional-quality shots from a tablet. Tablets take pictures worse than smartphones- it's not their main function. A feature of tablets is that their front cameras are usually no worse than the rear ones. The quality of the image from the front camera is important - after all, the user, in view of possible absence the call function on the tablet will surely chat on Skype.

If back and front camera tablets are capable of boasting a resolution of 5 megapixels, this is more than enough.

What else is worth paying attention to?

When choosing a tablet, the buyer should also pay attention to such minor points:

  • Housing material. Metal tablets are considered more reliable and look much more solid than plastic ones, but they catch Wi-Fi worse. Therefore, if the buyer intends to take a metal tablet, he should take care of 3G support.
  • OTG support. If the tablet is equipped with the On-The-Go (OTG) function, the user will be able to connect a USB flash drive to it and import / export documents literally on the go.
  • Stylus support. With the help of a stylus, it will be much more convenient and pleasant for the user to work with graphics. This material tells about the best tablets with a stylus.
  • Expandable memory. The amount of internal memory of the device is not so important if the memory can be expanded with a MicroSD flash drive. It is not difficult to buy such a flash drive now - they are sold for next to nothing.
  • GPS support /GLONASS. If the tablet is capable of receiving information from satellite systems, it’s time to spread the car navigator on Avito - mobile device cope with the laying of the route is not worse.

Conclusion

Going to the store for a tablet, the buyer must clearly understand how he will use mobile device. To check mail and VK “at home”, an option with Wi-Fi is suitable, but for work it is better to take a gadget that supports 3G. A Wi-Fi tablet is cheaper, but once it's out of range, many of its useful features become unavailable.

Answering a question for yourself WiFi or 3G, the buyer should pay attention to the performance and display characteristics of the device. By purchasing a 4-core device with 2 GB of RAM and a Full HD display, the user will hardly experience any inconvenience while surfing the Internet.
