OLED TVs - what it is, features and specifications

Today you can buy an LCD TV with a resolution of 4K, support for all the latest standards and excellent design is cheaper than 70 thousand rubles. However, OLED models offer significantly better contrast ratios. However, for most users, this technology is still prohibitively expensive. The price of an OLED TV, on average, is 70 thousand rubles more than an LCD model of the same size.

For this reason, the new technology is not very profitable when you need a large screen size. For example, a 4K projector is capable of giving a 120 ”image for half the price of an 77-inch OLED TV. The lack of projectors is that they need free space, as well as the ability to control the level of illumination in the viewing area, so they are not the best option for living rooms. Owners of rooms with a large number of windows without curtains will also have to confine themselves to LCD screens instead of OLED, since on bright sunny days, glare makes viewing difficult.

OLED TVs: what is it?

Models of this type are equipped with a screen made of organic LEDs. The main advantage of such displays is that the pixels themselves emit light, and do not use the backlight. This means that TVs can be much thinner because they don't need an extra layer of fluorescent or LED light sources to create images.

But not only the thickness of the model allows us to understand that this is an OLED TV. The ability of the device to control individual pixels is a more significant achievement. Since each pixel can be completely turned off, such TVs are capable of displaying truly deep black on the screen. They also have an almost instant response time.



The key difference between LCD and LED displays is how they create the image. LCD screens operate by passing light through a layer of liquid crystals. Since LCD pixels cannot close completely, they always let in a bit of light, even when the image should be black. Some LCD TVs produce darker colors than others, due to local dimming and other technologies,but they never provide zero brightness. The fact that this is an OLED TV is indicated by the presence of pixels emitting its own light. Therefore, when the section of the image should be black, it will be black absolutely.

The difference with almost black seems small, but in real life it makes a huge difference. The depth of the black, which is capable of playing TV, makes the rest of the image brighter, more alive, and allows you to better distinguish the elements of the image. Even when playing HDR content, for which absolute brightness is most important, OLED looks better than LCD displays, since the bright areas on a perfectly black background look much brighter.


Viewing angles

You can understand that this is an OLED-TV, and not an LCD display, by looking at the screen from a large angle. Most liquid crystal models suffer from significant changes in color and brightness even with a deviation of 20 ° from the center. The image on the OLED-display looks almost the same, no matter what angle you look at it. If the viewer is alone and always centered, he will not see the difference, but for a large group of people looking from different angles, OLED will look better.

Motion transmission

LCD televisions may suffer from image blur, as they need time to go from one color to another. OLED pixels change almost instantly. Thus, when watching sports or other programs with a rapidly changing action, the images will be clearer and more detailed. However, OLED technology is still not ideal for transmitting motion, because it uses the sample and hold method, but it works better than an LCD display.

OLED displays are brighter than plasma displays, but they are still not able to compete with LCD screens in overall brightness in lit rooms. In a room with a large number of open windows through which direct sunlight passes, LED pixels may not be the best option. For example, the current Sony OLED TVs display a 1000-nit display, but their full-screen white brightness is only 135–150 nit. The Sony X900F LCD screen can produce more than 500 nit, regardless of the displayed content, which makes it much easier to reduce glare and direct light in the room.


Although the risk of OLED screen burnout is low, it can still be damaged by displaying static content on it for a long time.This effect has no negative effect on liquid crystal displays. If you leave the TV set turned on at the same station with the logo for several hours a day or play the same game with static elements every day, then it is likely that the screen (for example, Sony's OLED TV) will burn out over time. Although the manufacturer has provided upgrade mechanisms to prevent this, they are not perfect. For most, this is not a problem, but there will always be exceptions, and, ultimately, the effect may be permanent. According to independent studies, in the worst-case scenarios, burnout occurs after viewing content with static screen elements for 20 hours.

Theoretically, the lifetime of an OLED TV is shorter than that of a liquid crystal. But in reality, when viewed for several hours a day, a model with any technology is likely to become technologically obsolete even before the image becomes too dark. LG predicts the duration of its panels to 100 thousand hours, which corresponds to 10 hours.viewing per day for 30 years.

This is one of the best examples of the implementation of screen technology on organic light-emitting diodes, proving that the 2017 model was not a phenomenon of one season. The line of high-tech products of the South Korean company in 2018 was headed by the 8th model of LG Signature OLED TV W. The TV managed to fill in the lost. As in its predecessor, an extraordinary approach to providing sound and images is used here. The screen and sound panel are separated - they are connected by a flat cable that connects to the port at the back.

The TV is only 2.57 mm thick and is attached to the wall with the supplied bracket and several carefully positioned magnets. As a result, the device looks like a frame for a photo.

The price of the LG Signature OLED TV W TV of the 8th model with a diagonal of 65 ”is 550 thousand rubles.


Special features

In terms of functionality, the 65 ”LG Signature OLED W8 has a lot in common with the 2017 model.

The soundbar is a hub for all ports. It contains 4 HDMI HDR inputs, compatible with 4K, 3 USB and digital optical connectors. Also included are TV tuners (cable, satellite and terrestrial) and a Bluetooth module.

The attractive LG WebOS operating system has largely remained the same. Some changes have been made to the text of the interface, the content store of the 65 ”LG Signature OLED TV has become more accurate, and a new search function has appeared on the main screen. All major services are included, including Netflix, Amazon, YouTube, Hulu and Google Play Movies.

As usual, the use of the launch bar and various menus is controlled by the Magic Remote motion detection system. At first glance, the interface seems attractive and intuitive, as before.

One of the additions to the LG Signature OLED TV in 2018 was the artificial intelligence of the ThinQ AI. It was created to make LG products even smarter, and allows you to use a more natural range of voice guidance. For example, you can now change the channel, find programs, or check the weather using a series of commands initiated by the microphone button on the remote control.

The appearance of the LG Alpha 9 graphics processor was great news. It became available for the entire W8 line. According to LG, A9 improves image quality on several fronts: reduces visual noise (at 4 levels), increases sharpness, improves depth and color reproduction.4K resolution is supported by a refresh rate of 120 fps and enhanced support for HDR content, including Dolby Vision, HDR10, Advanced HDR from Technicolor and HLG.

The TV provides high quality images and gives the user more control than, for example, Sony OLED TV. LG has integrated efficient calibration tools for Dolby Vision, SDR and HDR modes, but ISF Expert or Technicolor settings are very accurate. This is the best option for 4K and HDR formats, although 1080p and SDR on it also look good. Ultra-high definition video seems sharp and alive. Wide range of colors allows you to display colors that are not available to other models.

Watching OLED TV

According to LG, the filling of the sound bar on the LG Signature OLED TV has not changed. Its balance still leans towards mid and high frequencies, but it provides a good level of detail and clarity.

It seems to the listener that the sound radiates from the screen itself, and not from the speakers beneath it. Dolby Atmos creates a variety of sound effects and reverb, which further immerses the viewer in what is happening.


The factor of the novelty of thin, like wallpaper, LG models is still not lost. The fact that OLED TV is the future of visual display devices is obvious.And although so far some panels of this type have problems with uniformity at a 5% brightness level (vertical stripes are observed), it is often noticeable only on test patterns, and not when displaying real content. The main deterrent to the growing popularity of LG OLED TVs is price.
