What is ice backlighting on TVs? LED TVs – high-quality equipment at an affordable price

In recent years, televisions of this type have established themselves as a high-quality and reliable option. In this article we will look at what an LED TV is. Let's look at what LED means in detail. Despite the high cost, TV devices with such backlighting are popular.

What is a modern LED TV? This is a standard TV with an LCD screen, the matrix of which is illuminated by special LEDs. It would be worth calling LCD (LCD) TVs with LED backlighting. But the management of the South Korean brand Samsung calls such TVs “LED TV” for marketing purposes. This name has taken root in society. Let us remember that this company was the first to present televisions of this type.

In reality, LCD devices cannot be called real LED models. LEDs do not act as a real image unit - a pixel. LED-backlit TVs are a more modernized and improved version of LCD. Previously, CCFL cold cathode fluorescent lamps were used as a light source.

By replacing the CCFL backlight with LED, the developers eliminated several significant disadvantages of LCD devices:

they became thinner;
the amount of energy consumed has decreased;
Harmful chemicals are excluded from the composition.

The key feature of LED technology is that this device contains LED backlighting. In budget models it is located on the sides of the device (Edge LED). In flagships, the backlight is located at the back (Direct LED).

The first option uses exclusively white LED elements, and the second uses blue, green and red, known as RGB LED backlighting. In the backlight, the color elements are located behind the LCD panel. Diodes of different shades are turned on, which is affected by the incoming image color. Thanks to this, high resolution and image quality are achieved. Previously, such a picture was not available in conventional TV devices.

Let's consider what ICE means depending on the type of backlight and its placement.

Types of LED TVs

To understand the characteristic features of LED TV, it is necessary to dwell in detail on the types of backlighting. Today there are two classifications.

By color of light sources:

White LED (single-color system). Or white LEDs.

It is a cheap option, but more preferable compared to fluorescent lamps. Devices of this type consume a minimum of electricity. LEDs do not contain mercury. If we consider color transmission and coverage depth, LED TVs with this backlight are practically no different from LED LCDs.

RGB (multi-color system).

In this case, the color palette is much wider. This increases the quality of color reproduction. It should be noted that the price of an LED TV with this backlight technology is much higher. These devices need a powerful GPU. Among the disadvantages is the consumption of electricity in large quantities. If you have extra money, you can consider this type of TV device. All that remains is to choose the right TV.

QD Vision (mixed version).

The basis is blue LEDs with a special film with quantum dots (green and red).

This technology produces clear, confined and tuned optical waves. The color palette becomes wider, the colors become more intense. And this technology, unlike RGB, is considered energy efficient. Bravia TV panels are the first clear example of the use of a mixed lighting method by the Triluminos Sony manufacturer. As for the backlight placement technology, there are two options.

Along the edge of the LCD matrix (Edge LED). This is a one-color system, located on one side in most cases from the bottom. The manufacturer can also place it on parallel sides or along the entire perimeter.

The side lighting is affected by the size of the diagonal. Among the disadvantages of this method, it should be noted “lights” in the corners of the screen and a low level of contrast. At the same time, using such a scheme, the manufacturer creates panels a couple of millimeters thick.

Direct LED.

Principle: uniform distribution of diodes over the entire area. The price of such models is significantly higher. The advantage is that in this case it is possible to use local black dimming technology. The manufacturer can use white and colored LEDs. This will improve the picture quality.

Pros and cons of LED TVs

First, let's look at the advantages of LED TVs.

Small body thickness. By using LEDs it is possible to create ultra-thin TVs.
The image is contrasty and clear. Due to the reduced pixel response time, it was possible to achieve the most realistic image possible, even if there is dynamic movement on the screen. The viewing angle competes with plasma TV.
Energy efficiency. Almost a key advantage for buyers. The device consumes 40% less electricity than its predecessors.
Extensive model row, both in terms of functionality and design.
Lifetime. Due to the use of reliable and fade-resistant LEDs, the LED screen has a long service life.
Environmentally friendly product. No mercury. Moreover, LED TV safety documentation complies with all strict global principles.

Now for the cons:

Since local dimming technology is used to improve picture quality (LEDs are controlled by groups consisting of several diodes), TV models have the following disadvantages: presence of dark and bright spots in places where the backlight is activated and deactivated, there are colored halos at the transitions of contrasts. In dark areas, picture details may disappear. Viewing angles may also be limited.
Increased demands on signal qualityx. A low-resolution transmission on a TV will not look the best, showing all the disadvantages of the device.
An LED screen is considered an expensive pleasure. In most cases, these TV models are 40% more expensive than conventional LCDs.

Now you know the advantages and disadvantages of LED devices.

How to choose an LED TV

Choosing equipment, and especially an LED TV, is a pleasant chore. In order not to make a mistake when choosing the optimal device for yourself, you need to know what criteria you should pay attention to. Next, we will look at the nuances that you should keep in mind. This will allow the buyer not to get confused when choosing the right TV model.

LED TV backlight

Let's take a quick look at the pros and cons of Direct LED or Edge LED.

Positive aspects of Edge LED:

ultra-thin panel;
excellent contrast level;
high brightness.

Flaws:

there are problems with the uniform distribution of backlight in certain models;
There may be highlights around the edges.

Pros of Direct LED:

high contrast and brightness;
uniform illumination;
no glare around the edges.

Flaws:

panel thickness;
high energy consumption.

Screen resolution

You also need to consider screen resolution. Mostly models in the middle class are presented with Full HD resolution. If the diagonal is small, then HD Ready may be present.

Experts recommend choosing a TV with maximum resolution. Since there has been progress in the quality of television broadcasting. For example, the abandonment of analog TV in favor of digital TV is already in full swing.

Thickness and weight

If you plan to mount the TV on a plasterboard partition, it is better to give preference to light and thin TVs. If the TV will be placed on a stand or cabinet, these parameters do not matter. It is important that the stand matches the size of the device. For the first option, Edge LED is suitable.

Frame frequency

The frame rate of the TV signal in European countries is 50 Hz. This indicator is not enough to convey a dynamic scene. The picture will be choppy and blurry.

TV device manufacturers have added intermediate frames to solve this problem. As a result, a frequency of 100 Hz was obtained with the addition of 1 card between the previous and the next, 3 frames - 200 Hz. The task of the TV is to complete the intermediate frames. This technology was first used by the Samsung and Sony brands.

To increase the frame rate, scanning backlight was added. Modern models combine two technologies for maximum frame rates. If you intend to purchase a TV with 3D, then you need to opt for a high-frequency model.

To avoid making a mistake in your purchase, you need to ask the store consultant to turn on a dynamic scene. Look carefully at the image, the movements should be smooth and the contours clear.

Screen coating

Which screen coating should you choose – matte or glossy? The second option is characterized by a contrasting and bright image. Among the disadvantages are the glare that appears from the sun's rays. This is explained by the fact that the surface is slightly mirrored, so your eyes may get a little tired. The matte finish does not have such clarity, but there is no glare.

Consider the viewing angle. The larger it is, the less the picture is distorted when viewed from the side. Choose a TV with a viewing angle of at least 170 degrees.

Connectors

When choosing an LED TV, you should take into account the number of connectors on the rear panel. Today there is a lot of additional equipment that effectively interacts with the TV: DVD players, speaker systems, media players, receivers. To connect these devices, you will need the appropriate connectors. It is important that there are several HDMI interfaces, audio and video outputs, and USB connectors.

3D

Do you need 3D images? If you consider yourself to be a lover of modern technology, then a TV with a surround image will interest you. All 3D devices use 1 of 2 existing 3D imaging techniques: active or passive. Active technology uses glasses with an active shutter, which closes the eyes one at a time.

Glasses with liquid crystal lenses also interact with the TV device, using Bluetooth or an infrared port. This option is considered expensive, but at the same time it has its drawbacks. There is slight flicker. Add to this the additional cost of purchasing batteries.

The passive option divides the picture into two different polarizations. Due to different lenses, one eye will see the image from one polarization, the other from another. There is no need to purchase batteries. The main disadvantage is the halved image resolution. To choose a TV with 3D wisely, you need to look at two technologies in the store at once. Tilt your head, change your focus, move away from the TV. This is the only way to choose the best option for yourself.

Smart TV

Is it worth overpaying for smart TV features? A very interesting question. On the one hand, this is a really convenient option for viewing photos, videos and movies. You can access the Internet using Wi-Fi or use the LAN connector. Depending on the manufacturer, there are special widgets and browsers. This makes using the TV much easier. Smart TV reads data from an external USB drive. The device may not support all formats, much depends on the company.

Now you know what an LED TV is. What are the advantages and disadvantages of this type of TV. Moreover, you know what points to consider when choosing it.

When choosing the right TV model, many consumers are faced with new terms and modern technologies. For example, not everyone knows what a TV with LED technology is and what principle its operation is based on. Despite this, today this type of flat devices is most popular among buyers, so they are considered a completely familiar attribute in the home. Before you do it, you should still figure out what the abbreviation LED means, how such TVs differ, and what advantages they have over other types of TV.

If translated literally, then LED – light emitting diode. However, it is advisable to believe that it cannot serve as a complete definition. In fact, a modern LED TV is a representative of the long-known liquid crystal panels. The main component is an LCD matrix with many luminous dots - pixels. But if the usual LCD devices used fluorescent lamps as backlight, then the devices in question use LEDs, that is, TVs with such backlighting are more advanced options LCD-models.

Samsung developers were the first to use this technology. As a marketing ploy, the new TVs were given the name LED TV, which is still used today.

LEDs here act as light sources, and are not the actual unit of the image being formed. Therefore, it would be more correct to call such panels LCD TV with modern LED backlighting.

Types of LED backlight

In order to understand what the fundamental feature of such equipment is, you need to understand the types of TV backlighting. Today, several systems are used; they differ in color and arrangement.

By color of light sources

White led or single color system(white LEDs). It is considered a budget solution, but still outperforms fluorescent lamps. LEDs are energy efficient and do not contain mercury. As for color rendering and coverage depth, LED TVs with this type of backlight are not much different from LCDs; the difference is more significant in the next option.
RGB or multi-color system. Their color palette is much wider. Due to this, color rendition improves. But it is worth noting that models with a similar backlight option are more expensive, which is not commensurate with the achieved effect. Such models require a powerful graphics processor, and they consume more electricity. Since such HDTVs are not affordable for every group of consumers, leading companies decide to abandon RGB backlighting and continue to search for analog technology.
QD Vision or mixed backlight option. It is based on pure blue LEDs and a special film with quantum dots, which have green and red colors. This technology makes it possible to emit a strictly limited and tuned spectrum of optical waves. Due to this, the color palette and intensity of colors expands, at the same time, the technology, unlike RGB LEDs, is more energy efficient. A striking example of a mixed backlight option is the line of Bravia TV panels, the leading manufacturer of Triluminos Sony.

In fact, the question of using the first and second backlight options continues to find many controversial opinions. For example, the famous digital technology developer Toshiba claims that white TV backlighting is much more effective than RGB. So why spend a ton of money when you can save millions?

According to the lighting placement option

There are 2 options here.

Along the perimeter of the LCD matrix(Edge LED). This is a one-color system (White led), which can be located on one side (most often from the bottom), on parallel sides (on the sides) or along the entire perimeter. The method of organizing side lighting depends on the size of the screen diagonal. The disadvantages of such backlighting include “flares” at the edges of the TV screen and an insufficient level of contrast (compared to the second type). But this technology makes it possible to create panels only a few millimeters thick.
Directly behind the LCD matrix(Direct LED). It is based on the uniform distribution of diodes over the entire area. In terms of price, it is more expensive than edge lighting. The main advantage of such a system is the ability to use local black dimming technology. Both white and color LEDs can be used here; they significantly improve image quality.

If you already own such a TV and have problems with the image, you may find information about

Advantages of LED TVs

These panels have significant advantages, which is why they are popular among consumers. Of the main advantages, the following factors should be noted.

Case thickness. It is through the use of LEDs that the production of ultra-thin models has become possible. This TV can be easily mounted on the wall using a bracket;
Contrast and image clarity. LED TV is the main competitor of other types of TVs, as it has excellent image reproduction quality and adjustable contrast levels. Remembering when problems with the perception of moving objects were observed, it can be noted that with modern ice screens such problems will not arise.
Energy efficiency. Energy savings are perhaps the main point that attracts many buyers. Compared to its predecessors, the LED device consumes 40% less resources.
Wide range of models not only in functionality, but also in appearance. Such a panel will decorate absolutely any interior without any problems. Leading manufacturers have a huge number of models, implying both classic solutions and interesting shapes and colors.
Durability. Thanks to the use of fade-resistant LEDs, TVs have a longer service life.

But the improvement of such television panels does not end there. Already appearing on store shelves todayOLEDTV, the illumination of which is based on organic light-emitting diodes. They have an even thinner body, light weight (relative to their diagonal), a wide viewing angle, the absence of flare and glare, and excellent color rendition. However, this does not mean that other lower class models will lose demand. Innovative technologies of this format are not cheap, and the financial capabilities of most consumers will not allow having such a widescreen panel at home. Therefore, the demand for simple models of modern LED TVs is unlikely to fall in the near future. Detailed comparative characteristics of both types are given in the article

The modern TV market is very diverse and choosing the right model using the “like it or not like it” method is simply impossible. Many TVs are made using different technologies, and each has its own advantages and disadvantages. Therefore, today we will try to understand the basic parameters of the device so that you can determine for yourself which TV is better - plasma or LCD or LED, exactly for your needs.

What is what?

The principle of operation of the most common televisions (CRTs) is known to every person who has not skipped physics classes. This technique works as follows:

Inside the cathode ray tube, electrons knock photons out of the phosphor.
As a result of this action, each point on the screen acquires its own color.
Multi-colored dots make up an image, which is drawn line by line.

Important! The entire process is carried out at a speed of 25 frames per second.

Of course, the operation of conventional tube TVs caused certain problems for the consumer, namely:

The image flickers, and this negatively affects vision.
Electromagnetic radiation also does not add health.
The large dimensions of the device, due to the size of the tube, do not add comfort, especially in a small apartment.

Important! Conventional tube TVs are also inferior to modern analogues in terms of technical characteristics, such as contrast, image brightness, viewing angle. Therefore, few people welcome such devices; the question most often arises:Which TV is better - plasma or LCD or LED?

Modern television devices are mainly divided into two types:

Plasma.
Liquid crystal. Which, in turn, differ in the type of backlight and are divided into:
- LCD CCFL.

Let's look at the advantages and disadvantages of television technologies to figure out which TV is better - LCD or plasma. It should be noted that all TV market leaders are releasing devices with these new technologies. In our separate review you will find.

Plasma TVs

The technology of plasma devices is based on a matrix that is filled with gas (neon or xenon). Between two glasses placed next to each other, a small space is filled with gas, and an electrical grid of wires runs inside.

Important! The electrodes, receiving voltage, ionize the gas and turn it into plasma, causing the fluorescent elements to glow. Thousands of such elements of different colors reproduce the image.

The advantages of a plasma panel are obvious:

The image does not flicker. Frames change smoothly without creating color waves.
High contrast and color depth.
High-quality color saturation.
Natural transmission of movements.
Wide viewing angle (160-170 degrees).
The resolution of the plasma device is identical to the resolution of the input channel.
Sleek, slim design.
Modern design.
Larger selection of models with diagonals up to 80”.
Lack of electric and magnetic fields. This is important: firstly, there is no threat to health, and secondly, much less dust settles on the screen.
All modern models are equipped with computer connectors. If desired, the user can use the TV as an additional display for a computer or laptop.

Long service life (about 20 years).

Disadvantages of the plasma model

To decide which TV is better - plasma or LCD or LED, it is not a bad idea to familiarize yourself with the disadvantages of such, at first glance, ideal TV models:

The panel is prone to fading. Of course, you need to try hard for this, since the panel is designed for 30-40 thousand hours of use, which is 9 years, 8 hours a day.
Pixelation is visible due to high temperatures.
High power consumption. For example, a 42” model can use up to 350 W.
Considerable weight. Some models of plasma TVs weigh up to 90 kg, and to mount them on the wall you will need a powerful bracket.

Important! To understandFor the price, you need to know the following:
if you choose a large display size, then plasma models will be cheaper, since making a large liquid crystal matrix is much more difficult than plasma;
If you choose relatively small devices, then LCD TVs are cheaper.

LCD TV: LED or LCD?

The operating principle of an LCD TV is as follows:

Between the two panels there is a layer of liquid crystals.
The crystalline conductive liquid changes when exposed to electric current.
When the electric field is applied, the liquid crystal transmits a certain part of the light flux through itself: at one voltage, the pixel glows red, at another, white, and at a third, yellow.

Important! The crystalline conductive liquid must be illuminated so that the viewer can see the image.

Namely, according to the illumination method, this type of device is divided into:

LCD CCFL - liquid crystal display, backlit by a cold cathode fluorescent lamp.
LED - diode backlight.

Important! You need to know the designation of TVs based on the device principle in order to understandWhich TV is better - plasma or LCD or LED:
LCD and LCD are synonyms, that is, Russian and English abbreviations, respectively.
But LED is practically the same LCD, but with a different type of backlight.

What is the difference between the two types of LCD TVs?

LED TV, thanks to the backlight design, has better image quality. In LCD TVs, one lamp illuminates the entire screen, while in LED TVs there are a large number of LEDs, which makes it possible to create local dimming in one area of the display and simultaneously increase the brightness in another.
LED devices significantly reduce energy consumption. This type of lighting allows you to save up to 40% of electricity.
LED TVs do not use mercury. This advantage allows them to be safely disposed of.
LED TVs use diodes of different colors, which improves color reproduction.

LCD TVs eliminate the loss of image details and this is why they benefit from budget LED models, which, due to complex system diode control, incorrect color display may occur.

Advantages of LCD TVs

Let's note the main advantages of LCD TVs so that you can understand which TVs are better - LCD or plasma or LED:

Correct image geometry thanks to the flat surface of the LCD panel.
Clear picture reproduction.
Economical.
Low noise level.
Relatively low cost.

Important! Long service life is one of the undeniable advantages of this type of equipment. LCD TVs will last twice as long as plasma TVs, as they have a lifespan of 75,000 hours versus 30,000 hours.

Disadvantages of residential complexes:

Smaller viewing angle.
The contrast is lower than that of plasma. Black color is not saturated enough.
There is a danger of pixel burn-in.
LCD TVs are significantly smaller in size than LED or plasma models.

Advantages of LED

Models using LED technology in their characteristics are something between LCD and plasma:

The picture quality is much higher than that of LCD TVs.
They consume less electricity than plasma models.

Important! However, the price of modern models of LED devices is very high and not everyone can afford it.

Let's note the positive aspects of LED:

High image contrast.
High quality color rendering.
Wide viewing angle (average 160 degrees).
Economical.
Environmental friendliness.
The screen is very light, which is convenient for wall mounting.
Compactness. The average thickness of a TV is 3 cm.
Some models connect directly to the Internet and can replace a PC.

Important! The only reason why LED TVs have not replaced plasma and LCD is the high price. The disadvantages of the device include the fact that few of them have models with a diagonal of less than 40”. Therefore, if you want to buy a small TV, you will have to choose from plasma or LCD models.

Which is better: LCD or plasma TV?

The advantages of a plasma panel are quite obvious: the image does not flicker, nothing in the design threatens the health of TV viewers, there is more brightness and contrast, and the viewing angle is 160 degrees. The disadvantages include high energy consumption.

If you choose equipment based on performance characteristics, then analyze all the advantages and disadvantages of the two types of devices.

Advantages of Plasma in comparison with LCD:

High contrast and color depth.
Excellent color saturation.
Large screen surface.
More natural transmission of movements.

Advantages of the residential complex:

The screen does not burn out.
Wider viewing angle.
The operating resource is at least twice as large as that of Plasma. After the resource expires, you can only change the light source (lamp), and not the entire screen.
Low power consumption.

Important! The disadvantages of LCD TVs compared to Plasma include:
Color contrast suppresses midtones.
The natural transfer of movements is complicated by the problem of the “ghost frame” trail.

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, devices with such screens were called LCD TVs. 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 to produce 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) belong precisely to flagship models, and their price does not yet allow these TVs to be transferred to the mass category.

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 fact that the contrast of LCD screens was not high enough to compete with plasma or even picture tubes that were 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 backlighting 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. The best results in image quality are achieved 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 lighting 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 there are such a variety of TV models on the shelves that the consumer is simply lost and does not know what to choose. Before your eyes are dozens of screens of different sizes and thicknesses with incomprehensible words on explanatory signs. For example, if the sign indicates that the TV type is LED, what does this mean?

You know that the screens of some modern televisions are a liquid crystal matrix. If the matrix is illuminated from the inside with special LEDs, then it is an LED TV.

What is LED TV backlighting?

Edge LED

If you disassemble the TV, then behind the liquid crystal matrix along the perimeter of the body you can see many diodes that look like small light bulbs - this means that the TV has side lighting. The diffuser makes the screen illuminate evenly, but the backlight cannot be adjusted.

Matrix backlight (LED Backlight)

It is carried out by groups of diodes of three colors located over the entire surface of the panel. This method of illumination allows you to adjust it in individual areas, which allows you to achieve better color rendition.

What does LED TV mean for the consumer?

It is believed that this type of TV has a number of advantages over a conventional LCD TV.

How are LED TVs different?

TVs of this type have a more contrasting image;
the colors are very rich and natural;
LED TVs consume less energy;
The LED TV body is thinner;
The TV is capable of displaying a high-definition signal;
Screen viewing angles are maximum.

TVs are equipped with a number of connectors for connecting various devices and are even able to connect to the Internet.

Characteristics of LED TVs

permission. The resolution of LED TVs can be: Full HD and HD Ready. Full HD – the highest resolution;
sweep frequency. The scanning frequency can be up to 960 Hz. Higher scan rates will be required for 3D TVs;
matte or glossy screen. The glossy finish of the screen may cause glare. On matte, the viewing angle is not so great;
. If you are going to watch 3D movies, then choose between two display technologies and two types of glasses: active and passive. Determine by viewing which type is more suitable for you, is not irritating, and is comfortable for the eyes.
smart function. The smart function will be useful to you if you are going to go online. Choose a model with or without a built-in router.

So, you have made your decision and decided to purchase an LED TV. Where do we start choosing?

How to wipe LED TV?

In addition to all sorts of special liquids and wipes, which are available in abundance on store shelves, the TV is wiped with microfiber cloths. First slightly damp and immediately dry.

Using our tips, you will be able to choose the LED TV that best suits your needs and can save on features you don’t need.
