As early as the CES 2013 exhibition, Sharp launched an 8K resolution TV, which uses four-color technology, which is based on the three primary colors of red, green, and blue, and then adds a yellow element to make the picture color more tension. . However, Sharp did not disclose when this 85-inch 8K TV will be available, and the price is unknown.

8K TV is just to solve the larger and larger TV size and unable to expand the viewing distance indefinitely. Generally speaking, the best distance to watch TV is to see every corner of the picture clearly without turning your head. For a 50-inch LCD TV, the best viewing distance for HD-level TVs is about 4 meters, and upgrading to FHD resolution can shorten the distance to 1.5 meters.

In 2019, the market maturity of UHD TVs called "4K" has entered a milestone stage. The "Chinese Color TV Consumption and Trend Forecast Report for the Second Half of the Year from January to June 2019" released by the China Electronics Chamber of Commerce shows Monthly China's color TV consumption was 22 million units, of which 4K ultra-high-definition TV consumption accounted for 70%, and 4K TV has entered the stage of full popularization. At the same time, "more promising display technology-8K resolution" has also arrived, it is considered to be the next generation of display technology to replace 4K resolution.

8K TV debuts, 4K resolution TV gives way to most markets

In fact, as an advanced version of 4K TV, 8K TV has officially entered the market, and quickly entered the growth stage. The Strategy Analytics report predicts that by 2025, there will be more than 50 million households worldwide with 8K-level TV sets. By then, global sales of 8K TVs will soar to 30 million sets per year. The aforementioned "Report" also pointed out that China's 8K color TV consumption in 2019 is expected to reach 60,000 units. In the data released by Futuresource Consulting, it is also confirmed that by 2023, the sales of 8K TVs will grow at a compound annual growth rate of 130% from 200,000 units in 2019.

According to the "Ultra-HD Video Industry Development Action Plan (2019-2022)" jointly released by the Ministry of Industry and Information Technology, the State Administration of Radio and Television and the Central Radio and Television Station, China has established the overall technology of "4K first, 8K in consideration" The line is to basically improve the domestic 4K industrial ecosystem in 2020, and breakthroughs have also been made in the research and development and industrialization of 8K key technology products. Technically, the commercialization of the fifth generation wireless communication network (5G) has also greatly solved the problem of bandwidth constraints.

Under the favorable conditions, 8K TVs will undoubtedly become the best choice for high-end TVs for elite users.

Why do you need a higher resolution TV

Why do you need a higher resolution TV?

In order to solve the problem that the public often confuses the professional abbreviations such as "FHD, UHD", the industry adopts the resolution as the main parameter to distinguish the generation method, and the horizontal pixel value of the TV panel 3840 or 7680 is extracted and rounded , And call it 4K TV, 8K TV.

For example, "8K TV" is a common name for a digital TV set that contains 7680 pixels in the horizontal direction and 4320 pixels in the vertical direction. Therefore, the pixel value provided by the 8K TV is four times the pixel value of the 4K TV, which means that under the same size screen conditions, the picture of the 8K TV is more delicate and clear than the 4K TV. It is also the highest display on the current civilian large screen. level.

In the history of TV resolution evolution, the technology that represents the next generation characterized by higher resolution usually experiences a short period of "obscurity and resistance" on the consumer side. Similar to the surprising acceptance of 4K TVs appearing on the market for the first time, for the top TV player products, the market is still filled with arguments such as "lack of 8K sources" and "why higher resolution TVs are needed". So why do users who are already using 4K TVs need to buy a "higher resolution" TV?

The most direct reason is that the application of higher resolution on TV is to balance the relationship between the realism of human vision and the limited distance between man and machine. People need to solve the problem that the image quality declines on larger screen TVs at a distance that cannot be extended infinitely. Illusion haunts.

8K TV is just to solve the larger and larger TV size and unable to expand the viewing distance indefinitely. Generally speaking, the best distance to watch TV is to see every corner of the picture clearly without turning the head. For a 50-inch LCD TV, the best viewing distance for HD-level TVs is about 4 meters, and upgrading to FHD resolution can shorten the distance to 1.5 meters.

With the launch of the global high-generation LCD panel production line, small-sized screens have gradually withdrawn from the mainstream supply market. For example, the economical cutting specifications of the 10.5 generation line are 65-85-inch panel products, and larger 4K TVs are needed in small living rooms. Re-plan and solve the embarrassing sight problem. For 8K TVs with a resolution that exceeds four times the resolution of 4K, 98-inch large-screen TVs will not experience visual discomfort at the original man-machine distance. Instead, they will benefit from the new generation of audio and video technology in the living room scene. With the upgrade of comprehensive parameters, the movie watching experience is comparable to the IMAX theater.

Real 8K TV is not just about resolution

Not all TVs with a resolution of 7680 × 4320 are called 8K TVs. To measure whether a TV is a true 8K TV, it is not only a simple picture that reaches 30 million pixels per frame, 8K in the true sense TVs also need to have at least 8K arithmetic processing, 12bit color depth, AI sound effects, HDMI2.1 and other standards, and 8K resolution combined into a "five arts true 8K TV."

8K lets your eyes see the real world

Quantum dot 8K processor: AI intelligent image enhancement

Faced with the high-end user group, 8K TV has been launched on the market, and it still cannot fully solve the status quo of video content. The continued lack of 8K content will inhibit the growth of consumer demand. Samsung TV creatively developed a quantum dot 8K processor chip. The 8K AI Upscaling quantum dot 8K processor can effectively reduce image noise, supplement the restoration of distorted picture details, improve picture quality and sound effects, and allow viewers to enjoy any video content at a resolution close to 8K .

The AI ​​chip relies on machine learning to optimize for different scenes, scans the content below 8K frame by frame, reconstructs the image edges by erasing edge aliasing, reducing noise, and further enriching the picture, improving the picture quality and enhancing the picture details. Whether the content is from HDMI, USB transmission or streaming media, set-top boxes, or even mobile content, this patented technology can get rid of the limitations of the original resource resolution, rely on machine learning to select the best image texture, reduce the picture Noise, reconstruct the edges of the image, quickly optimize the content of SD, HD, FHD, 4K and other resolutions to close to 8K level to obtain extremely realistic pictures. The super processing power of AI and 8K combined makes the problem of temporary shortage of 8K resources Perfect solution. The quantum dot 8K processor chip has been applied to the new QLED 8K TV launched by Samsung in 2019.

12bit color depth: display 68.7 billion colors

The next-generation improved ultra-high-definition Blu-ray Ultra HD Blu-ray standard (BT.2020) has been determined, and one of the important indicators is that the video reaches the 12bit color depth standard, which puts strict requirements on the TV ’s 68.7 billion color display capabilities . Compared with the 8-bit color depth, there are only 16.77 million colors of ordinary blue light standard, and the improvement of color richness is self-evident.

HDMI2.1 all-around high-speed channel

To achieve a 12-bit color depth at 8K resolution, it is very difficult and challenging for any TV manufacturer. Not only does it have strict requirements for the HDR standard, but it also needs to abandon the old field transmission standard. The specification adopts the transmission interface of HDMI2.1 version. The HDMI2.1 standard officially released in 2017 increased the transmission bandwidth from 18G to 48G, thereby supporting a color depth of up to 16bit at 8K 60Hz, and also supports enhanced audio return channel (eARC), variable refresh rate (VRR), fast Media switching (QMS), fast frame transmission (QFT), and automatic low-latency mode, so the HDMI2.1 interface is standard in the 8K era.

In the dazzling battle of 8K TV in the first year, when buying 8K TV, in addition to paying attention to the resolution parameters, consumers also need to realize that a TV with "high strength and five arts" is the real 8K TV.
