Tablet resolution. Touchpad type


Screen size

Diagonal up to 7 inches- the most portable tablets, it is recommended to use for reading books, browsing the Internet, photos.

Diagonal 7-10 inches- the most popular models, due to the screen size, are more convenient for watching movies, Internet sites, and are also suitable for working with office programs and for computer games. Less compact, however, quite convenient on the road.

Screen type

Resistive- outdated touch screens that respond to any touch, both fingers and hard objects. Today they are practically not produced.

Capacitive- designed for touching with a finger or a special stylus. Supports multi-touch technology - the ability of the device to respond to the simultaneous pressing of two points on the screen. All actions that can be performed are intuitive to the user. For example, sliding two fingers on an image will reduce its size, rotating with two fingers will rotate the image, etc. The optimal supported number of simultaneous keystrokes today is - 5 .

Screen resolution

The higher the resolution, the more detailed the image will be. Today for comfortable watching movies High Quality, websites and solving other problems, for tablets with a diagonal of 7 inches, resolution is desirable 1280x800 pixels (or better 1920x1080 Full HD), for diagonals 8-10 inches - optimal resolution 1920x1080. Many expensive tablets use Retina displays with resolution 2048x1536(for example, Apple products).

Aspect Ratio

Most models have an aspect ratio of 4:3 - great for browsing websites or reading books.

Widescreen screens in tablets have an aspect ratio of 16:9 or 16:10, which allows you to comfortably watch modern movies without black bars at the top and bottom of the screen.

Pixel Density

PPI(from the English "pixels per inch") - a characteristic of the image quality on the tablet screen. Indicates the number of pixels per inch of screen. The higher this parameter, the smaller the pixels, which means the better the picture.

An excellent PPI value today is 250-300 or more. At approximately this value, the pixels on the smartphone screen are indistinguishable.

Important: It is worth noting that PPI is an optional parameter specified by the manufacturer. This is a calculated characteristic. You can find it out using the formula or using special calculators on the Internet.

operating system

Android- the most popular OS, the interface of which is designed for maximum convenient use touch screen tablet. Many programs have been developed for this operating system, which can be downloaded for free directly from your tablet. Particularly popular Google apps: mail, Google Maps, Google+ and others. You can connect your Android tablet to your computer like a regular flash drive.

Current OS update today - Android 6.0.

iOS- also a convenient and intuitive OS for touch screen control, but is used only in tablets manufactured by Apple. Most applications for this OS are paid, and you can also download them directly from your tablet. To connect such a device to a PC, you need to install iTunes.

Latest OS version - iOS 9.

Windows 7/8- it is also possible to install this OS not only on personal computers, but also on tablets. It is more demanding on the tablet configuration, so it should be chosen only if you need to solve some problems that Anodroid and iOS cannot handle. Allows you to connect the device to your computer as usual removable drive or flash drive.

An update is available today for some tablets Windows 10, and some models are already sold with it.

The leading operating systems are Android and iOS - they are the least demanding on the “stuffing” of tablets. New versions of the OS are constantly being released, which correct the shortcomings of the previous ones, and many applications are being developed.

Processor and memory

Choosing a processor and volume random access memory largely depends on the operating system that the tablet supports:

  • iOS - minimum frequency 1 GHz processor and recommended memory 1 GB.
  • Android- requires a dual- or quad-core processor, 2 GB of memory is recommended for smooth operation;
  • Windows- the requirements are much higher - 1.3 GHz processor and 2 GB of memory.

The higher the processor frequency, the higher the speed of the tablet. Choosing a more powerful processor expands the range of activities you can do, such as watching high-definition movies or playing modern games.

When choosing the amount of RAM you should remember that for additional applications Not all of it will be available, because... part will always be occupied by the operating system.

The most popular families of processors (chipsets with an integrated processor) for tablets: Intel Atom, Cortex, Apple, Nvidia Tegra, etc.

Built-in memory

The built-in memory of the tablet is implemented in the form flash memory. Maximum size today - 750 GB (Gigabytes).

Some tablet models support expandable internal memory, for example, various formats. Before purchasing a memory card, make sure that its format is supported by your tablet.

Working hours

This characteristic depends on several parameters: battery capacity, processor type, as well as the processes running on the tablet. For example, when listening to music, the operating time will be longer than when watching movies.

You should choose a tablet depending on its purpose; if you plan to take it with you on long trips and do not depend on sockets, then it is recommended to pay attention to tablets with a maximum operating time of 10-14 hours.

Equipment

WiFi- the tablet has a built-in Wi-Fi adapter, with which you can connect to wireless network Wi-Fi.

Bluetooth- the tablet has a built-in Bluetooth module, with which you can connect a device that supports Bluetooth technology. For example, headphones or a headset. And also transfer information to other devices with Bluetooth. Modern standard Bluetooth 3.0 - allows you to forward large files with high speed, and the newest Buetooth 4.0 - less energy-intensive.

Function cell phone - the ability to use the tablet as a mobile phone with support for a regular mini SIM card, micro SIM cards or nano SIM cards.

  • Dual SIM cards- some models support dual SIM cards.

3G support- the ability of the tablet to connect to cellular networks 3G (and its subsequent versions) to get faster Internet.

Strained glass- some models are equipped with special protective glass that is resistant to scratches and light damage. As a rule, this is Gorilla Glass from Corning. It should be remembered that such protection will not protect the tablet screen if it falls on a hard surface.

4G LTE support - last generation high-speed cellular networks.

Camera- presence of cameras in the tablet: rear and/or frontal. The rear camera is located on the back of the tablet and is usually used for taking pictures. Front - on the front, directly above the screen, used to provide video communication with interlocutors. By quality front-camera inferior to the rear. Built-in cameras may have a flash and autofocus function.

  • Video HD- by using latest models tablets can record high-resolution videos.

Dock station- The kit includes a docking station with which you can attach the tablet. Often a full QWERTY keyboard is built into the docking station, making the tablet much more convenient for entering text.

Tablets can also be equipped with devices such as compass, accelerometer, gyroscope, light sensor and etc.

Manufacturer

The tablet computer market has existed for several decades, although its rapid development began only with its release in April 2010 Apple of the Year iPad. What attracted consumers and manufacturers to the “new” type of mobile devices? First of all, mobility, small size and long time battery life— you will agree that these are precisely the parameters that were simply unavailable for a long time. However, if you look back, you can remember that ten years ago there was another class of devices that closely resembled modern tablets - handheld computers, or PDAs. Moreover, their popularity was quite high. However, we won’t delve into history - let’s better see what it has to offer us modern market tablet computers.

And it has a lot to offer: store shelves are literally replete with numerous products, as they say, for every taste and budget. There are a lot of manufacturers - starting from famous brands and ending with unfamiliar companies whose name does not evoke any associations among buyers. In general, the competition is in full swing: eminent manufacturers, under severe pressure from numerous factories from the Middle Kingdom, are forced to reduce prices, and the latter, in turn, come up with more and more new “features” so as not to be left out of technological progress.

So, let's see what such abundance can please us with. We decided to test six models of tablet computers made by leading manufacturers and tell readers about their advantages and disadvantages.

Samsung Galaxy Tab Pro 8.4(average cost 16,500 rub.)

Samsung has always been famous for its most serious approach to the design of its products. This time too, the designers did their best - the device turned out to be nice, elegant and attractive.

Slim body made of plastic, while the entire front panel is covered with glass covering the display. The build quality is excellent, the only thing that bothers me is the dirtiness of not only the glossy display, but also the rear surfaces.

There are two speakers, so the sound here is all right. Of course, you can’t call it ideal, but the volume is more than enough. Of course, there are also 2-megapixel video cameras. frontal and equipped with 8-megapixel autofocus. the main one, located on the back cover of the device.

Perhaps the most interesting thing about the new product is the display - with a diagonal of 8.4 inches, it supports a resolution of 2560x1600 pixels. The matrix is ​​made using Super Clear LCD technology, which provides excellent brightness and contrast, although there are certain complaints about the accuracy of color reproduction - the saturation is artificially increased, so the colors are too rich and completely natural. However, it looks good, moreover, even when working in bright sunlight, the screen remains readable.

The device is built on the basis of a 2.3 GHz quad-core Qualcomm processor Snapdragon 800, while the Adreno 330 GPU acts as a video accelerator. The RAM capacity is 2 GB, and 32 GB of ROM is intended for storing information. If this volume is not enough, you can use the slot for microSD cards. Navigation capabilities are provided GPS modules and GLONASS, and for wireless communication Dual-band Wi-Fi 802.11a/b/g/n/ac and Bluetooth 4.0 with A2DP respond.

The 4800 mAh battery allows you to last up to eight hours without recharging in video viewing mode. Naturally, games are more power-hungry - when used, the battery life is reduced to three and a half hours.

Asus MeMO Pad FHD 10 (me302c)(average cost 11,500 rub.)

The design of this tablet can be called classic - a rectangular body with rounded edges, not burdened by unnecessary controls, a structured back cover that gives the device a touch of elegance and a large 10-inch display framed by a black insert.

The material is plastic, although, by and large, the workmanship is quite high, the product looks monolithic. There is a front 1.2 megapixel. camera and even a pair of speakers located at the back, so there are no problems with sound in movies and games - of course, this is not home cinema, but not a soap box either.

The screen with a resolution of 1920x1200 pixels is made using IPS technology. One of its features is a special coating, which, according to the manufacturer, protects the display from scratches and mechanical damage. The viewing angles are great, the brightness margin is also good, so using the tablet indoors does not cause any discomfort. But direct sunlight is clearly contraindicated for it - glare appears and even maximum brightness does not save from a sharp decrease in the readability of the display. For settings color range A special utility is provided so that the user can select the color rendition based on his own perception.

The model is based on Intel platforms Atom Z2560, based on a dual-core processor with clock frequency 1.6 GHz, complemented by the PowerVR SGX 544MP video adapter with low power consumption. The amount of RAM is 2 GB, while 16 GB are allocated for data storage. All this coupled with powerful processor provides good performance, allowing you to comfortably use any modern gaming applications.

Battery operation also does not cause any complaints. The 6760 mAh battery lasts for six hours of video playback or four hours of intense gaming - the result is quite good.

LG G Pad 8.3(average cost 12,000 rub.)

This model is produced by a company that pays close attention to appearance of their products, so it is quite natural that both the design and the materials used in production do not cause any complaints.

The body is made of aluminum and plastic, which gives the appearance of this device solidity and elegance. Interestingly, the use of metal in no way affected the weight of the device: its weight does not exceed 338 g - this is even less than that of many “plastic” competitors.

The display is an 8.3-inch matrix with a resolution of 1920x1200 pixels, made using IPS technology. Viewing angles are beyond praise, brightness and contrast are also excellent. Naturally, with such a high resolution, the picture looks simply magnificent - its clarity is due to high density pixels Perhaps the only drawback is that in bright sunlight the screen becomes completely blind and it becomes impossible to see anything on it.

Directly above the screen there is a front-facing 1.3-megapixel camera used for video communication. Naturally, there is a second one, 5-megapixel, designed for the needs of photo and video shooting. Unlike the front one, it is equipped with autofocus.

The main component of the hardware is a quad-core 1.7 GHz processor Qualcomm Snapdragon 600, supplemented by 2 GB of RAM and 16 GB of ROM. The configuration is really not bad - its performance is enough for comfortable use of gaming applications, and the interface does not slow down at all.

The capacity of the built-in battery is 4600 mAh. Accordingly, the battery life is not particularly high - with the wireless interfaces films can be watched for five hours, whereas maximum performance reduces this figure to just over three.

Apple iPad Air(average cost 32,000 rub.)

Of course, Apple is a generally recognized world leader in the production of all kinds of mobile devices, which is very difficult for other manufacturers to compete with. This time, too, it offered consumers an interesting device that stands out for its exquisite design and excellent workmanship.

The model is based on the dual-core 1.4-GHz Apple A7 processor, which became the first 64-bit processor based on the ARM architecture (for mobile devices, of course). A nice addition 1 GB of RAM and 128 GB of ROM serve - the performance is excellent, both the interface and applications simply “fly”.

Main material from which it is made iPad Air- aluminum. The design is recognizable, it has not changed since the 2nd generation model. The only thing that makes the new model stand out is that it has become thinner and smaller - this has happened due to a significant reduction in the frames framing the device’s screen.

There are still two cameras, and the front one now has a resolution of 1.2 megapixels, while the main iSight has not undergone any changes.

iPad Air is equipped with a Retina display with a resolution of 2048x1536 pixels. As protective coating a glass plate with a mirror-smooth surface protrudes, equipped with an oleophobic coating that prevents fingerprints. The main indicators are in perfect order - brightness, contrast, and viewing angles do not cause any complaints. The only thing I didn’t like was working in bright light sunlight— the screen noticeably glares and the image on it becomes difficult to see.

As for battery life, everything is fine here too. A capacious 11,560 mAh battery allows you not to get close to electrical outlet from two to seven days. This is an excellent indicator, although the battery charge time is quite long.

Apple iPad mini 2 Retina(average cost 20,000 rub.)

I remember that at one time Apple management stubbornly insisted that the diagonal of a tablet computer screen could not be less than 10 inches. However, in 2012, marketers nevertheless insisted on their own, which resulted in the release of a smaller version of the tablet, which quickly won the sympathy of consumers. This time we got the next reincarnation, which received a new display and more powerful filling.

In principle, the appearance of this device resembles a cross between a classic iPad and iPhone. Nevertheless, the device turned out to be not only interesting and attractive, but also quite unique. The main material used in its manufacture is aluminum. The usual frame framing the display has been reduced to a minimum, and the body itself has become a little more austere and angular.

The display diagonal of the model is 7.9 inches with an aspect ratio of 4:3 and a resolution of 2048x1536 pixels. Available protective glass and an oleophobic coating, so it is not afraid of fingerprints. The color rendering quality is good, brightness and contrast also do not cause negative emotions, so the only drawback is the inability to work in bright sunlight.

The sensitivity of the touch sensor is quite good, and the viewing angles are simply excellent, both horizontally and vertically.

The heart of the device is a 64-bit 1.3 GHz Apple processor A7, complemented by 1 GB of RAM. Interestingly, the configuration is exactly the same as the iPad Air, and accordingly, the system performance is the same as that of the older model.

The tablet uses a built-in battery with a capacity of 4500 mAh as a battery. Testing has shown that it is enough for five and a half hours of video playback - in principle, the result is not a record, but quite good.

Amazon Kindle Fire HDX 8.9(average cost 13,500 rub.)

Following the release of several e-book models that quickly gained worldwide popularity, the famous American online store decided to present to users its new vision of a modern tablet computer.

The strict rectangular body is made in dark colors, which gives the device a certain solidity. The front panel is a single glossy surface(by the way, it’s quite easily soiled), while all other elements have a practical soft-touch coating. The material is plastic, although the quality of its processing does not raise any complaints.

There are two speakers, their volume is quite enough, although sophisticated music lovers are unlikely to like the quality. There are two cameras - 1.3-megapixel front and 8-megapixel rear. There is autofocus and LED flash.

The screen is not bad at all. It is based on an 8.9-inch IPS matrix with a resolution of 2560x1600 pixels, respectively, the viewing angles are simply excellent. Brightness and contrast are also excellent, although the display fades noticeably in bright sunlight. The sensor is capacitive, there is also a Gorilla Glass coating that protects against scratches and damage, so in this regard everything is in perfect order.

The hardware is built on the basis of a quad-core Qualcomm Snapdragon 800 processor, complemented by an Adreno 330 video accelerator. RAM is 2 GB, but the ROM is represented only by built-in 16 GB of memory; there is no possibility of expansion using cards.

The model runs the Kindle Fire Mojito 3.0 operating system, based on Android 4.2 OS. It has its own set of standard applications (Launcher, Appstore, Calendar, Contacts, Email, Gallery, Silk Browser, Swype Keyboard) and is optimized for working with Amazon services.

The built-in 3700 mAh battery lasts for six hours of video viewing or three and a half hours of intense gaming - a good result, but not ideal.

To sum up our review, we can say that, compared to other sectors of the computer market, tablets are developing very quickly. Power is growing, display quality is improving, and new technologies are emerging.

As for our preferences, the "Best Buy" badge this time goes to Asus tablet MeMO Pad FHD 10 (me302c), which is due to its good characteristics at a more than attractive price. "Editor's Choice" rightfully goes to Apple models iPad Air - despite the high price, this device has a very interesting design, excellent performance and thoughtful functionality.

Hello, readers of the IT lessons site!

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

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

Question from Yanina:

Good afternoon
I have 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 it have? best picture scanned e-books?
Thank you!

We learned what a tablet is back in . Today, as you already understand, 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 for the human eye. A little more about this in this article.

A little about the PDF format

PDF format created for electronic versions of 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... It’s 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 (you can select text);
  • Unrecognized (in the form of a picture, text cannot be selected).

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

Tablet screen diagonal

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

Everyone's vision is different, so before purchasing check whether the text is clearly visible to you, whether your eyes will strain, whether you will have to enlarge 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 the 7-7.7 inch options. If the option is a backpack bag, then pay attention to 8-10 inches.

Tablet screen resolution

On 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 small, then you will see the image divided into dots (called “pixelation”).

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

Moreover, for the same diagonal there can be different resolutions. Let me give you a couple of examples.

Example:

Tablets with resolution 800×480 may have a diagonal 4 to 9 inches. On a four-inch device, reading books in PDF will be difficult (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 from 7 to 13.3 inches.
Those. tablets from 7 to 9 inches can differ in the number of points by almost three times. But for reading scanned books a high resolution will be redundant.

conclusions

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.

The tablet computer market today is not expanding as actively as the smartphone segment. Firstly, such devices are rarely changed annually, and secondly, the niche for selling them is narrowly focused. From this, the rating of tablets with good screen becomes even more interesting, because when choosing a gadget for several years you really want to get quality option. In order to save you from the agony of choice, we selected based on user reviews best models 2017, among which you will definitely find a solution to suit your individual preferences.

Xiaomi MiPad 2 16GB

The Xiaomi MiPad 2 tablet, which created a real sensation among many users, was honored to open our rating. Devices of this class do not deserve such special attention very often. This success is explained by the fact that this inexpensive, but good tablet, in terms of characteristics it surpasses many of its competitors of a higher price segment. There is a high-quality 7.9″ IPS matrix with a resolution of 2048x1536 pixels, an Intel Atom processor operating at 2.2 GHz, and even powerful battery 6190 mAh, which sometimes even larger models cannot boast of. If you are looking budget tablet, characterized by compactness, good performance, pleasant design and good quality manufacturing, then MiPad 2 from Xiaomi should definitely interest you. The only drawback of this model is the somewhat outdated Android version 5.1, but this is a rather subjective disadvantage, so it will not be critical for all users.

Do you want to choose a tablet with a good, bright 8-inch display at a reasonable price and without any frills? In this case it is still current model Galaxy Tab Samsung's S2 may be perfect for you! This is a very popular tablet with 4G, offering a very convenient 4:3 screen format (resolution 2048x1536 pixels), high-quality body materials, a capacious 4000 mAh battery and good hardware. According to reviews of the tablet on the forums, it copes well with any task, and even modern games run on it without any problems. As for autonomy, in video playback mode this model will work on a single charge for approximately 14 hours. The manufacturer managed to achieve this result not only through excellent optimization, but also thanks to the use of the processor own development Exynos 5433. It contains 4 Cortex-A57 and A53 cores, operating at frequencies of 1.9 and 1.3 GHz, respectively.

If you are looking for the most best tablet in terms of weight and dimensions, then be sure to pay attention to this model. The name of the Phab line itself suggests that this is a phablet, and therefore it can be used both as a smartphone and as a convenient tablet. At the same time, the device is quite compact, which is ensured by minimal frames on the sides, although it is unlikely to be carried in trouser pockets. In terms of price-quality ratio, the tablet is good choice, because for its price the gadget offers a 6.4-inch display with Quad HD resolution, 16 and 8 MP camera resolutions allow you to create excellent shots when shooting, an 8-core processor from Qualcomm, as well as 4 GB of RAM and 64 GB of internal storage, respectively .

If you don’t yet know which tablet to choose with a good screen and battery, Phab 2 Pro will be an excellent choice for you.

Huawei MediaPad M3 8.4 32GB LTE

Just 5 years ago it was difficult to even imagine that a quality product could be included in the rating Chinese tablet has a good screen. However, Huawei has been proving its importance in the mobile device market for many years now, which it again managed to do with the MediaPad M3. Excellent 8.4″ IPS screen with a resolution of 2560x1600, a self-developed Kirin 950 processor, which is one of the best on the market, Android 6.0 “on board” and the presence of two slots for SIM cards. The amount of RAM here is also very impressive, amounting to as much as 4 gigabytes. The built-in storage can be 32 or 64 GB, but it can be easily expanded using micro cards SD up to 128 GB (replaces one of the SIMs). It is noteworthy that in the online store this tablet can be purchased for around 24,000 rubles, which makes it a very interesting option for purchase.

ASUS ZenPad 10 Z500KL 32GB

The ZenPad 10 Z500KL from Asus is one of the high-quality devices on the market demonstrated by the manufacturer this year. Despite this, the company is not trying to reinvent the wheel by adding expensive but completely unnecessary features to its 10-inch tablet.

When choosing specific model Tablet computer is worth paying 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 execution technology.

Tablet screen sizes.

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

The first one has a screen size of 5-6 inches diagonally. Tablet computers belonging to this group are primarily distinguished by their compact size and slightly larger standard smartphones. Graphic picture displayed on such a screen is different high definition, but small in size. The undoubted advantage of this group is the long battery life of the devices, since the smaller the screen, the less electricity consumption will be.

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

The third group is devices with a screen size of 9-10 inches. The dimensions of such a tablet may seem too large at first glance. 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, and surf the Internet.

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

Types of matrices and manufacturing technologies.

The most common one is 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 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 capable of transmitting the widest range of colors and low level energy consumption.

Most new development modern tablet manufacturers are technology Super Clear LCD. The main difference between screens using this technology- maintaining high image quality and contrast, regardless of lighting brightness and viewing angles. Simply put, you can work comfortably with these tablets in bright sunlight 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 have a resolution of 1024x768 pixels, eight-inch screens have 1280x800 pixels, and so on.

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