Features of TVs with a resolution of 8k. Televisions LG, Sharp with a resolution of 8k

If the fashion for certain functionalities of the modern TV arises and completely disappears, the clarity of the image is in the field of view of consumers constantly.

Devices with a high resolution blew up the market, which was disgusted by old receivers with a picture of poor quality, and now they are replaced by a technique with 4K precision. This is four times more than that of Full HD TVs.

Not really, it's true, it's clear why the resolution is given the main attention, because there are other image parameters that can have at least the same value as the number of pixels used. But the sales figures speak for themselves.

Generation 8K

Knowing this, you can be sure that a huge number of employees of developmental and research departments of all major television brands are busy developing receivers with even more screen pixels than the 3840x2160 for 4K.

What really came as a surprise was the sales of 8k-enabled devices, though oriented towards the super-elite segment of the market.

8K-TVs provide an incredible quality image, which is confirmed by the products of such manufacturers as LG, Samsung and Sharp. And in each case the picture is so good that it almost does not lend itself to description. Mainly due to the fact that even on huge demonstration screens of 80 inches and more than 33 million points simply do not allow to see any traces of the visible pixel structure of the image.

This means, in essence, that the viewer as though looks through a large window into the world that the retina of the eye perceives as real.

So why is there no certainty that the 8K time has already come? First, to take advantage of such a high resolution, you need a really big screen. Today's 4K is enough for any display up to 65 inches, maybe even 75 inches.

Secondly, video content in such a huge quality is almost impossible to get. Even four years after the appearance of 4K, the need to provide sufficient bandwidth continues to cause a headache in telecoms due to the huge amount of data that is required to view UHD video. It is easy to imagine what awaits the video industry when it encounters a truly colossal amount of data related to the use of 8K.

Olympiad in ultra-high definition

In Japan, NHK is working on the creation of 8K-broadcasting for the 2020 Olympic Games. Already in August at the Olympic Games in Rio will be shot 130 hours of video in ultra-high resolution and will broadcast the opening and closing ceremonies.

It is impossible to imagine such an experiment in any other place in such a short time. Therefore, most people will be able to watch only scaled 4K-video or HD-content. The calculations necessary for this will be a really difficult task even for the most powerful video processors.

CES 2016

Samsung and LG presented 8K-TVs at CES 2016, which was held in Las Vegas in early March. Sharp, however, has already started sales in Asia at a price of 16 thousand US dollars.

Sharp 8K-LED-TV Aquos LC-80XU930X was presented at the exhibition CES 2015. The device is manufactured using Quattron technology, which allows dividing the pixels into 4 parts. Thanks to this and achieved 8K-resolution. At the moment, however, the device is not yet capable of broadcasting full 8K content, but only images with ultra-high definition. In addition, the resolution increase works only when the viewers are very close to the screen.

Pseudo 8K

In terms of specification, 8K-TVs have LED backlight and anti-glare panel N-Black. Run on Android, equipped with Netflix and compatible with HDR-technology video transmission with an extended range of brightness, which allows you to increase the contrast and transfer more shades of color and detail in dark areas.

Receiver sales are currently going to Singapore, Malaysia and Japan with the prospect of expanding to all Asian countries in the near future. The price of the device is 16 000 US dollars.

Last September, 85-inch Sharp 8K-TV LV-85001 appeared. The LCD display consists of 7680 x 4320 pixels, and the device price was 133 thousand US dollars. This means that only rich and famous plus large enterprises will be able to acquire it, at least at first.

The TV Super Hi Vision 8K LV-85001 uses indium, gallium and zinc oxide (IGZO) technology, which, at low power consumption, emits radiation over a wide range of wavelengths.

98-inch from LG

Along with the 18-inch folding display and thin paper-like OLED devices, LG presented a 98-inch 8K-TV with a resolution of 7680 4320 UH9800, which boasts a new Super MHL interface, first demonstrated by Samsung in its own prototype 8K-TV At CES 2015. In addition, Sharp also presented earlier prototypes of ultra-high definition displays at CES in 2012 and 2014.

Although the final characteristics of the 98UH9800 are not yet known, its main functions in addition to the resolution and SuperMHL include:

• IPS LCD panel providing a wider viewing angle.
• HDR, improving the brightness and contrast of HDR-content.
• Color Prime Plus for a wider color gamut.
• WebOS 3.0, the latest version of the LG Smart TV platform, which provides easy navigation and quick access to streaming network broadcasting and media content.

Distinctive features of WebOS 3.0

In addition, it was possible to divide the screen into two different channels, or one channel and another source, for example, a Blu-ray disc player. You can also start the music player with the TV turned off and control the home appliances via the IoTV Internet application.

Magic Zoom increases any area of the screen without losing image quality, the "magic console" will allow you to control the prefix, and using the function "magic cellular communication", like Apple's AirPlay, you can broadcast applications from your smartphone to the TV screen.

SuperMHL

The key element of creating a user-friendly user interface was the integration of SuperMHL technology. It provides a single connection of the 8K signal source (for example, set-top boxes, disc players, media-timers) to the TV. The previous prototypes required four HDMI connections to provide enough bandwidth for transferring video and audio.

In addition, SuperMHL provides a video speed of ultra-high definition at 120 fps (HDMI 2.0 allows only 24 fps) at 48-bit color depth with wide coverage as per specification VT.2020, power supply up to 40W.

Speaking of audio, the standard, promoted by NHK, supports 22.2 audio channels. This is more than enough to support all existing surround formats, as well as those that will appear in the future. Nevertheless, it remains to be seen whether this potential will be realized at the consumer level.

The price for LG's 8K-TVs is still unknown, but the company promises to begin selling it by the end of 2016 and, most likely, by special order.

Perhaps, LG is risking, betting on 8K. But it should be borne in mind that doubts about the company's ability to support OLED technology were dispelled after the success of the latest generation of OLED TVs, also presented at CES 2016.

8K from Samsung

During the event Samsung also presented the world's first 8K-TV UN98S9 measuring 98 inches, equipped with 10-bit quantum dots and Ultra Black technology, which allow to achieve a clear image and minimize glare. The device features a lack of framing, curved design and Internet support of IoT stuff.

Quantum points

A quantum dot is an artificial nanocrystal with semiconductor properties that are used to improve the brightness and color reproduction of static images and video on LCD screens. When it receives photons from an external light source (blue LED), the light is emitted, whose wavelength and color, respectively, depend on the crystal size. Large nanocrystals emit red, and smaller ones - green light. In combination with the main blue, a full-color image is formed, the characteristics of which exceed the capabilities of modern displays.

Downsampling master copies

Although 8K-resolution has yet to go a long way to get into the mainstream, its use is now growing in the restoration of films and the creation of master copies in film studios that specialize in preserving classical films in digital format 8K for recording on Blu-ray discs , And other copies of ultra-high definition.

Despite the fact that the main high-definition formats currently used are 1080p and 4K, recording with a master copy of 8K provides the best quality. In addition, this means that there is no need to constantly increase the clarity of the master copy every time a new image format appears.

Too early?

There is an opinion that 8K-TVs will only harm the nascent 4K-TV market. In the end, nothing stops people from buying a new technology, as the consciousness that the next generation of TV receivers is just around the corner.

To be fair, it should be noted that the huge cost of the first commercially available ultra-high definition TVs means that buyers will have to purchase 4K. And the sale of 8K-devices seems even more crazy enterprise, as producers cut the branch on which they sit.
