Choosing a TV for your home. LED TV

Facebook

In 2016, the development of television technology brought LED-backlit TVs to the peak of popularity; they are called “ice TVs.” Also today in stores you will find television receivers with OLED-based screens.

LED TVs are television receivers in which the screen is built on a liquid crystal matrix (LCD) backlit by LEDs.

The liquid crystal matrix is abbreviated in English as “LCD” (liquid crystal display). And previously this is what devices with such screens were called - LCD TV s. But for the liquid crystal screen to work, it needs a backlight, and for the first few years a CCFL fluorescent lamp was used for backlighting. Then light-emitting diodes (LEDs) began to be used to operate the backlight. And now TVs with liquid crystal displays are called “LED TVs”, which is the same as “LCD TVs”. The differences in these names are only in the form of backlighting; all other parameters and operating principles remain the same.

As of 2014, all companies stopped producing LCD TVs backlit by a fluorescent lamp. Models are available with liquid crystal screens and LED backlighting. And today such television receivers constitute the most widespread and affordable segment of televisions. Plasma models are already leaving the market, there are only a few companies left that continue production plasma TVs and these are just a few new models in 2014, and these are not flagship models. But devices with OLED screens (screens based on light-emitting diodes) are precisely flagship models, and their price does not yet allow these TVs to become mass-produced.

Differences between LED and conventional LCD

When using lamps to backlight the matrices, it was impossible to adjust the backlight of individual areas of the screen. This led to the contrast LCD screens was not high enough to compete with plasma or even picture tubes still alive at that time. Therefore, we came to the decision to use LEDs to illuminate the matrix. At the same time, it became possible to adjust the backlight in individual areas by adjusting the brightness of individual LEDs.

This is where we get advantages of LED backlight Compared to a conventional fluorescent lamp:

improved screen brightness,
contrast,
color rendering,
and energy consumption has decreased by up to 40%.

Due to the small size of the LEDs and the overall thickness of the LED TV body, it is smaller than others.

Differences in backlighting between CCFL and LED

LED lighting methods

There are two types of LED backlight: side and back. Side (Edge) lighting, in which LEDs are located around the perimeter of the TV body. Backlight (Direct) illumination, in which the LEDs are located evenly behind the matrix. top scores The image quality is provided by Direct backlighting with the ability to locally dim groups of LEDs. Edge backlighting is cheaper, so it is more used in TV production

How the backlight works

The main problem of LCD screens was contrast, or rather its low value. Contrast is the ratio of the brightness in the brightest area of the screen to the brightness in the darkest area. Screen manufacturers have tried to adjust the backlight brightness in different areas to increase contrast. That's why it appeared local dimming technology, which allows you to control groups of several LEDs at once. The local dimming system has several disadvantages. Firstly, poor color uniformity (bright and dark spots are noticeable) in areas where the backlight is brightly turned on and off. Secondly, colored halos appear at contrasting transitions. Thirdly, image details disappear in dark areas. But the increase in contrast and black level compensates for these shortcomings.

If we rank different technologies according to the indicator quality of the resulting picture, then you get the following result:

LED backlight using the Direct method;
LED lighting using the Edge method;
CCFL lamp backlight.

Today's LED TV models have screen resolutions from HD Ready to Full HD, and this year there are also models with 4K Ultra HD resolution. LED models can also have functions such as 3D, Smart TV, a wide variety of connectors and other parameters. So every buyer among the models of LED TVs will be able to choose a suitable purchase for himself.

Today, the variety of television equipment is very high. All of them differ in the principle of image formation, the technology of its illumination, as well as the presence of additional technological delights. Despite this, the choice in favor of one type of TV or another is becoming easier to make, as pass-through types such as plasma and projection are becoming a thing of the past. LCD TV began to occupy a dominant position in the market, although just a few years ago the debate over which was better - LCD or plasma, was very heated, but with the development of liquid crystal technology, the operating principle of which is based on polarization luminous flux, the controversy faded away, and plasma models faded into oblivion, giving way to LCD TVs.
LED or LCD?

Choose a good option

Often, when we go to a store, we choose a device primarily by size and price. But there are many other factors that also need to be taken into account.

So let's figure out which option to choose - led or lcd, what possibilities are hidden behind the abbreviation, led TVs - what does this actually mean, why have they become so popular lately.

The essence of this question is to find out which TV is better, but this approach to comparison is fundamentally wrong, since LED denotes the matrix backlight technology, and LCD is, in fact, the matrix itself, inside which the image is formed. A similar, erroneous attempt to compare is that an inexperienced buyer is trying to understand what is better - LCD or ice.

Partially understanding the difference will help to understand the terminology. The abbreviation LCD comes from the English Liquid-Crystal Display, which means “liquid crystal display”, and LED (light emitting diode) is translated as “light emitting diode”. Therefore, it is inappropriate to compare a screen and a light bulb, especially since the concepts of lcd and led are related, do not contradict each other and coexist perfectly in most modern models. Moreover, LCD matrices with backlighting other than LED are becoming increasingly rare.

Such a false comparison in the minds of ordinary people did not arise by chance - it is the result of the planting of a marketing idea. It was she who promoted LED as a fundamentally different type of technology, leaving behind the scenes that, in fact, it is only a fundamentally different type of backlight, which replaced the fluorescent backlight in the same LCD TV.

Undeniable advantages allow ice lighting to differ from fluorescent lighting, otherwise it would not have become so widespread. After all, LED TV backlights have not only supplanted fluorescent ones, they have practically driven them out of the market, not least because LEDs are cheaper to produce.

Another undeniable plus in receiving the title “best” is environmental friendliness: LED TVs, or rather LEDs, do not contain mercury, which they cannot boast of fluorescent lamps.

A very strong argument in favor of purchasing LED equipment is the presence of much higher performance characteristics compared to models with the old type of backlighting. One of the differences is that LEDs burn longer and do not dim during operation. As a result, such a TV works without loss of image quality. And the service life of the device is a significant factor in the choice.

Important nuances when choosing a TV

Separately, you need to dwell on how to choose a LED TV. Despite the seeming obviousness and simplicity of choosing the type of device, you need to understand that LEDs are different, and in order to choose the right one, it doesn’t hurt to understand what qualitative differences characterize such TVs and how they are expressed.

The main factors that you should pay attention to when choosing an LCD TV are:

The principle of screen illumination with LEDs

This is directly related to how the technology is implemented. It is impossible not to mention how LCD TVs differ from fundamentally different technology - OLED (organic light-emitting diodes).

The difference between models with OLED displays is that the LEDs here do not illuminate the matrix with white light, thereby illuminating the image, but rather form the image themselves. The matrix of such a display consists of many LEDs, each of which emits the desired color of a certain intensity. This fundamentally affects not only the quality of the picture, which is a level higher here, but also the cost, which in turn hinders the mass distribution of this technology. In addition, OLED displays have much more short term service, approximately 2–3 years, which is also a limiting factor for its spread. At the same time, the service life of LED TVs is about seven years.

On this moment OLED technology is distinctive feature premium segment of TVs, and here each buyer, based on his budget, decides which one to get - LED or OLED.

Illumination Uniformity

Depends on the number of LEDs.
Of course, you won’t be able to count them, but before purchasing you should pay attention to the degree of uniformity of the screen’s glow. It is advisable to check this not on a beautiful high-resolution picture, but on solid colors - then it will be easier to see highlights. However, on TV from famous brands, even in budget segment, this practically never happens; it is mainly the manufacturers of Chinese brands who are guilty of this.

On high-definition televisions price segment so-called carpet lighting is used, which is characterized by the fact that the LEDs are located immediately behind the display, and are evenly and fairly densely distributed over its entire area. In addition to uniformity, this method also allows you to control the brightness of the glow in a particular area on the screen. In practice, this allows you to reduce the intensity of the glow in those areas of the screen where you want to achieve deeper blacks. It must be said that this is a very uncommon technology, and not all brands implement this approach well. The most commonly used schemes are those in which LEDs are placed in two garlands, one each at the top and bottom of the display, or in several such garlands, symmetrically distributed directly behind the screen.

Glow brightness

This determines how well the screen will be visible when daylight. Many people probably know what it’s like to watch a movie or a program when the entire picture is illuminated by the sun. Therefore, it is worth paying attention to this point if you plan to use the TV in brightly lit rooms, or if it will be located opposite a window. In any case, the brightness, if it is excessive, can be reduced.
Guided by these points, you will already know exactly how to choose the right LED TV.

SMART TV

It is also worth mentioning such a concept as smart, with which the era of smart television began.

It does not relate to quality and does not affect the picture, however, a buyer who makes a choice of an LED TV inevitably encounters this term when he comes to the store to make a purchase, and therefore it is better to be aware of whether it is necessary to spend money on the purchase smart device, or you can do without it. In fact, a smart TV contains an additional module that is used to access the Internet and only acts as a monitor.

A smart TV is distinguished by the ability to access the Internet, provided that an Internet cable is connected to it. The result is a kind of symbiosis between TV and computer.

In general, when buying a TV, you need to understand that watching television channels at home and watching a promotional video in a store are not the same thing. A TV can produce the best quality only if you watch TV channels in high resolution or HD content.

Thus, knowing how LCD differs from OLED and smart, you can consciously approach the choice of a TV with the required technical characteristics.

LED TV is a TV with a liquid crystal screen that uses LEDs to backlight it. For example, other LCD TVs that came out earlier used a cold cathode to backlight the screen. It is believed that LED TVs have the best image quality, unlike previous models TVs, namely: color quality, contrast, color depth, brightness and other parameters.

The image quality is affected by a new technology called local dimming. This technology is responsible for local dimming of the screen, which increases the picture quality several times. Unfortunately, this technology has some disadvantages, for example: poor color uniformity in the image, color halos may appear in contrast transitions, and some details may disappear in dark areas of the image.

Types of LED TVs

It is worth noting that LED TVs are divided into two subtypes based on the way the LEDs are arranged, these are: Direct and Edge. Direct implies the placement of LEDs evenly, behind the screen, and when using Edge technology, in turn, the LEDs will be located along the entire perimeter of the screen, together with the diffusion panel.

Each of these technologies has its own advantages and disadvantages. For example, Direct allows you to get a more uniform backlight, but this will increase the thickness of the screen itself, and therefore the TV, and in addition, energy consumption will increase. This is due to the fact that when using this method the number of LEDs is increasing. Thin or ultra-thin TVs are created using Edge technology, which is the complete opposite.

As mentioned above, the cost of LED TVs is decreasing today. This is due to the advent of televisions with improved IPS technology. Such TVs have better color reproduction than LED TVs, high levels of brightness and contrast, high image clarity and many other advantages.

As a result, when choosing a TV based on the type of backlight, a person may make a mistake, since it does not always have a decisive influence on the image quality. The type of graphics processor, as well as image processing technology, plays a big role in this.

Every person, when choosing a TV for himself, learns about latest achievements science, gets acquainted with new technologies and terms. One of modern technologies in the field of television is LED. In reality, an LED TV is an ordinary liquid crystal LCD TV. This means that the image in it is formed using a matrix consisting of pixels.

If in older devices the backlight was a fluorescent lamp, then in LED models the backlight is a matrix consisting of a set of LEDs (Light Emitting Diode).

Light Emitting Diode is translated as “light emitting diode”. The scope of their application is extensive: these are car headlights, traffic lights, lamps, spotlights, street and home lamps. In a TV, light from LEDs is directed onto the LCD screen, illuminating the image.

Of course, it would be more logical to call these models LCD TVs with LED backlighting. However Samsung company, which is a pioneer in this field, called these models "LED TV". The term became popular and began to denote a class of new televisions. The LEDs in these TV receivers do not form a picture as a real unit (pixel). Therefore, LED TVs cannot be considered full-fledged LED models.

How LED lighting works

To understand the operating principles and features of this device, you need to become familiar with the types of backlighting on a TV. Currently, several lighting systems have been developed. They differ from each other in their location and color.

Color of glow sources

Single color system (White led) more energy efficient than fluorescent lamps, but is still considered a budget option. LEDs do not contain mercury, like lamps, but in terms of color rendering and coverage depth, LED TVs with this backlight are practically no different from LCDs.

Multi-color system (RGB) compares favorably with the previous version. TVs with this backlight have a wide color palette. Accordingly, very good color rendition. Unfortunately, this effect comes at a higher price. To operate such models you need a modern, powerful GPU. These TVs consume more electricity and have a more bulky body, comparatively speaking, of course. The cost of these TVs limits demand, so leading companies are gradually abandoning RGB backlighting and are looking towards analog household appliances.

Mixed backlight option (QD VIsion) uses only blue LEDs and special films. The film is a collection of quantum dots that have red and green colors. This allows you to have a tuned spectrum of optical waves, limited in range. Due to this, the color palette expands, and the brightness and intensity improves. Unlike the RGB system, this technology is more energy efficient.

The answer to the question of which backlight option to use is ambiguous. There are still various controversial opinions and discussions on this matter. Toshiba believes that white backlighting, based on all its characteristics, is preferable to RGB.

Accommodation options

There are two options for placing the backlight:

General advantages of LED TVs

These devices are an undoubted step forward in the development of television. They enjoy deserved popularity in everyday life. There are several main advantages:

Manufacturers are constantly working to improve these panels. The new technology is called OLED TV. In these TVs, the backlight is organized using organic light-emitting diodes. They are even more characteristic slim body and improved color rendering.

Speaking about LED technologies, we should not forget that in the manufacture of LED TVs they do not use, as before, harmful substances - mercury and aerosols.

Some LED-TV models use “local dimming” technology. It is designed for local dimming. The basic idea is to control groups of LEDs. Each group contains several elements. True, with this approach, bright spots sometimes appear in certain areas of the screen in those areas where the backlight is turned on at full power. And where the backlight is not used, dark spots may appear.

Screen resolution. Determined by the number of pixels that form the image in width and height. The higher this parameter, the clearer the image and the more different details you can see on the screen.

LED-TVs mainly have Full HD (1980×1920 pixels) and H.D. Ready (1366×768 pixels) resolution. These are the most popular formats video in currently. Some premium models have 4K UHD resolution (3840x2160 pixels).

Almost all 4K UHD TVs support HDR. This is an extended format dynamic range, which allows you to depict a picture as close to reality as possible.

Screen coating. There are matte and glossy. At matte finish the image is softer. Viewing angle is limited. When hit sunlight no glare. If the coating is glossy, then the picture on the screen is very bright and contrasting. Visibility becomes poorer in bright sunlight.

Functional connectors. Usually there are standard ones: HDMI output, Ethernet output and USB connector for watching video from a flash drive or hard media. IN latest models there is a D-sub video port. It involves connecting a computer to a TV.

Sweep frequency. An indicator of how many frames of a film are shown per second. It is measured in Hertz and can reach values up to 960 Hz. For 3D TVs, the frequency can be even higher. The recommended range of values so that the image does not blur and pictures do not overlap one another is 100−200 Hz.

Additional features

DVB-T. Standard digital television. Allows, in addition to analog cable and terrestrial television, connect satellite.

Volumetric 3D image. Using this option, you can view 3D images with active or passive 3D. It is necessary to take care of special glasses.

Smart TV. Allows you to connect and use the Internet. Connection occurs via WiFi module. Connection via network cable is possible. Some TVs allow you to build in an additional router. With Smart T.V. you can play videos from the Internet, play, listen to music, and search for information.

LED devices have become popular. After all, LED TV - what does it mean? This is high quality, convenient and comfortable to use. The advantage of LCD TV is LED lights, available for all LED models. But for design features, additional features sometimes you have to pay extra. What should you pay attention to when choosing an LED TV model?

First of all, you need to decide which diagonal is best to choose. Available in stores huge selection different models from 19 to 58 inches. Sometimes it’s not very common to calculate in inches and you have to select the size in centimeters, that is, from 48 to 147 cm. Right choice diagonal depends on the size of the room where the TV will be installed.

There is an approximate table of the ratio of diagonal and distance to comfortable viewing.

These data are approximate and allow adjustments within half a meter.

14−17 inches - from 1.5 to 2 m.
21−25 inches - from 2 to 3 m.
26−32 inches - from 3 to 4 m.
34−37 inches - from 4 to 5 m.
42−55 inches - from 5 to 7 m.
61−80 inches - from 7 to 10 m.

So, when choosing a TV, you need to think about its location in the room in advance and select optimal model, based on the layout.

After choosing the TV diagonal, you need to consider the resolution. Here the criterion is the larger the better. Full HD will provide complete comfort and satisfaction from your TV.

The quality of the picture is assessed subjectively. If possible, colors should be natural, without overexposed areas or spots. The image during fast movement should not be jerky, but smooth. The black color must be free of impurities, as black as possible. You should check the transmission of halftones to see if the details are different. The color of the human body: hands, face should be pleasant, without yellow or red spots.

Manufacturers need to be well-known. In addition to the guarantee, this also includes service, as well as the availability of various additional parts and accessories in stores and service centers.

And of course you need to think about additional functions. Do you need Internet access or how important is it to connect your laptop to a large screen?

What is the difference between an LCD and an LED TV?

LED technologies are gradually replacing liquid crystal technologies, since the former are more efficient and economical. This is a serious energy saving and best picture on the screen. Although the differences between these LCD and LED approaches lie only in the way the screen itself is illuminated.

Everything is moving forward. Modern films are produced for latest technologies. Therefore, in order to fully immerse yourself in the atmosphere of the new film, it is better to watch it on LED-TV.

Today, devices with LED backlighting - The best decision in terms of image quality and equipment cost. Modern solutions in televisions of this type allow them to compete with expensive plasmas(PDP), confidently displacing the latter from the market.

True OLED TVs are very promising. In these panels, LEDs are truly the imaging unit. But these models are still expensive and only pay for themselves with very large screen sizes.

Attention, TODAY only!

If in the evenings you want to enjoy watching your favorite films, series and TV shows, then you just need to purchase good LED TV. Currently, equipment manufacturers offer great amount such devices at different prices. Find out what an LED TV is. These TV panels have a huge number of advantages and will delight their owners with high-quality, bright images.

What are LED TVs

An LED TV is a device that is a TV receiver with a liquid crystal screen. The matrix is equipped with a special backlight from a set of LEDs. Explanation of the abbreviation LED - “Light Emitting Diode”. From a technical point of view, it would be more correct to call such devices liquid crystal with LED backlighting. However, Samsung was the first to launch such a device on the market under the name “LED TV”. Other manufacturers adopted it, so it became common.

LED backlight

Nowadays different types of such devices are produced. They differ in the type of LEDs used and the order of their location in relation to the screen. By lamp color:

Single color (White LED). A budget option. It does not have the disadvantages of fluorescent backlighting and creates an image with a similar color gamut, but not as contrasty.
Multi-colored (basic RGB LED color triad). Color palette expanded due to LED brightness control. The number of semitones has been increased. To support this technology you need a powerful GPU. The model will cost more and consume more energy.
Mixed. Blue LED backlight and special film with green and red quantum dots. This technology reduces the device's power consumption.

We found out what LED backlighting is on a TV. In addition to the color of the lamps, it differs in their location. There are two options:

Directly behind the LCD matrix. Direct backlight type Full or Direct LED. These models are cheaper than Edge, but not as thin. WITH high level contrast. They have white and multi-colored LEDs.
Along the perimeter of the LCD matrix. Edge LED backlight type. LEDs can be located on one (bottom), two (side) or four sides of the screen. Thanks to this, manufacturers produce models less than 1 cm thick in these LED devices white. Budget models made using this technology have a drawback. They show highlights along the edges of the screen. In addition, they have a low contrast level.

Characteristics

There is a huge variety of models on the market from different manufacturers. They differ in price depending on the parameters they have. To make it easier to choose a model based on your budget when purchasing, learn to at least understand key characteristics features of an LED TV:

Permission. There are several options: Full HD, HD Ready, Ultra HD. The latter is considered the best.
Smart function. Thanks to this option, you can access the Internet directly from the device. There are models with and without a built-in router.
Sweep frequency. Shows how many times the image is updated per unit of time.
3D image function. If you plan to watch films in this format, then choose from two display technology options: active and passive. Compare both options in the store and determine which is more comfortable for your eyes.
Matte or glossy screen. The first one does not have such a large viewing angle, but the second one has glare.

Advantages

An LED TV is nothing more than an LCD screen, but improved. LCDs used to use CCFL cold cathode fluorescent lamps as the light source. They were replaced with LED lighting. This freed liquid crystal devices from their characteristic disadvantages. Thanks to LED technology, TVs have become thinner (especially Edge models). They are environmentally cleaner and more energy efficient, do not contain mercury, and do not require specialized disposal. Advantages:

more contrast image compared to other technologies;
maximum screen viewing angles;
rich and natural colors;
consumption of a relatively small amount of energy;
display signals high definition;
thin body.

How to choose an LED TV

Buying equipment for your home is a very important moment that needs to be approached with the utmost seriousness. It is important to go to stores with a good reputation that guarantee the quality of their products. You can either buy an LED TV or order it from an online store with delivery from Moscow or St. Petersburg to your home by mail. It is profitable to buy equipment before the holidays; during such periods, stores often have sales and promotions and offer excellent discounts. Tips for choosing an LED TV:

Screen diagonal. This is one of the most important indicators. Many people think that bigger screen- all the better. Optimal size should be calculated as follows: divide the estimated distance from the viewing location to the LED TV by three. The diagonal should be equal to the number you get.
Screen resolution. The best for today, but also the most expensive, will be an LED TV Ultra format HD.
Image quality. This option should be selected based on personal preferences. In stores, as a rule, there are a lot of working TVs broadcasting the same file. Compare which one you like better.
Screen covering. Glossy is more contrasty and brighter. However, it is not suitable for a room with a lot of sun, it will glare. Matte makes the image less clear, but is not shiny at all.
Format. The most popular at the moment is 16:9. Suitable for both digital and satellite television. The second 4:3 format option is suitable for cable channels.
Manufacturer. Buy only products from companies that have been on the market for a long time and have proven themselves well. Pay attention to reviews online.
Settings. The more options you can adjust, the better. On some budget models It is impossible to even change the brightness of the image.
Additional functions. Modern LED TVs come equipped with many options that are not critically necessary: voice control, wi-fi, built-in router. Assess your budget and decide which bells and whistles you need.
A set of functional connectors. It is better to purchase a TV that has HDMI and USB ports for connecting other devices. Check whether the connectors are conveniently located and whether access to them will be difficult.
