8K is coming! Do we really need her?

However, for the 8K standard, there are a lot of buzzwords. The core point of view is: 4K is still subject to the lack of content, how to have "4 times 4K" 8K survival basis? Way to go step by step, rice to stutter. This view has become mainstream. People are worried about how far the 8K of scarce content can go.

In the 8K era, how did the panel maker think?

On August 31, Sharp released the world's first consumer-grade 8K TV in Shanghai, Taiwan, Tokyo and Berlin. Sharp sharply disregarded AQUOS LCD-70SX970A, priced at 68,888 yuan.

September 7, 2017 International Winter Sports (Beijing) Expo, National Convention Center, BOE (BOE) shocked to launch a full range of 8K display product camps, including 27-inch, 65-inch, 75-inch, 98-inch and 110-inch 8K products .

One is Sharp, the father of LCD, and the other is the largest display panel manufacturer in the country. Both of them invariably add 8K frequency. Fully demonstrated the panel industry's confidence in 8K technology.

In fact, the 8K of the display panel, especially the 8K of the LCD product, is not a technical problem: it is to think of a 5.5-inch mobile phone screen that can achieve a 2K resolution and dozens of inches of TV screens. The resolution is not "water is good".

Insiders pointed out that 8K large-size display panels are highly mature in terms of technology and yield. However, currently, 8K products are produced only rarely, and they are experimental productions. This kind of low-volume manufacturing is the main reason for the high temporary cost. Never before, the cost difference between 8K and 4K is basically the same as the 4K and 2K cost difference. At present, the cost of large-size LCD panels, 2K and 1366*768 products is basically the same.

That is, on large-size display products, high resolution does not mean "higher cost." In fact, the 65-inch 4K is the same size as the 32-inch 2K pixel. Considering the process of cutting a small-sized module from a large-sized substrate, the technical difficulty is almost the same. The 80-inch 8K product is similar to the 40-inch 4K product. The technical specifications are similar, and there is no significant difference in technology and cost.

Therefore, 8K itself should not be regarded as "technical difficulties" and "cost problems" when the 8K is combined with the large-size color TV trend. The only problem is precisely in downstream applications.

Content restrictions 8K, broadcasting system how to plan

Taking the domestic color TV market as an example, 4K products already occupy half of the river. However, in the content industry, real 4K content is not even enough for Chengdu.

Why is content so slow? Because, the content involves more links in the industry chain. Including advances in camera technology, advances in storage technology, and advances in transmission technology. Compared with the current 2K products popularized by broadcasting systems, 4K is 4 times the amount of data, while 8K is 16 times the amount of data. A set of upstream content systems that can carry such large data flows has become a bottleneck that really restricts market development.

Moreover, from the standpoint of broadcasting and TV stations, the time for high-definition and full-HD broadcasting is not long: that is, the broadcasting system has a relatively new, up-to-middle-year 2K standard upstream content technology and equipment system. This system has just passed the cost depreciation period, which is currently a stable high-yield output period. At this time, coming up with a 4K or 8K standard requires a large exchange of blood for the radio and television system. There can be no resistance.

Therefore, at present, 4K or 8K, more shows that manufacturers are very keen - the analysis above, for the display business now has no technical suspense; and manufacturers always want to create more advanced standards The product. However, although the content industry is optimistic about new technical standards, there is no "specific benefits to drive equipment and technology upgrades." Instead, considering that the deployment time of 2K systems is not long, many units prefer to "conserve the old."

This situation has not existed in history: At the beginning of this century, the broadcasting and TV department experienced the “first decade” of the three standards of digitalization, high-definition, and full-HD. Of the three standards, high-definition has almost become a "direct skip phase." The reason is that soon after digitization, it was high-definition, and soon afterwards there was the concept of full-HD. This makes the radio and television system that "HD 720p" up and down without edges.

For 8K, the history of broadcasting and TV industry may repeat: the transition of 2K, 4K, and 8K standards is not carried out in sequence, but directly skips 4K. Because, 4K and 2K are too close to each other, followed by an 8K. This is also an embarrassing position.

In fact, there are two steps to the definition of the ultra-high-definition standard for broadcasting systems in the future: to achieve the 4K technology with low difficulty and then implement the 8K standard. As early as 1995 Japan NHK conducted 8K technology research. 8K radio and television imaging technology has also been applied experimentally in the Aichi Expo in 2005, the London 2012 Olympic Games and the 2016 Brazil Olympic Games. 8K technology also became an official international standard in 2012. Tokyo Olympics in 2020 is ready to fully implement the 8K live broadcast. In the 2022 Beijing Winter Olympics, 8K will also be a new broadcast standard.

On the contrary, from the perspective of broadcasting and television, 4K technology has not been paid much attention: because the first broadcasting system needs to maintain the leading position of new technologies; second, it needs to maintain a longer period between the two major technical changes. The time difference is to recover the cost of the last technology upgrade. The two decided that the color TV industry may not usher in the popularity of 4K, but when the time is ripe, it will jump directly to the 8K level.

Targeting 8K, "Strategic" Selection of Color TV Industry

From digital TV to HD, Full HD, Ultra HD 4K, and today's 8K, the number of display pixels is getting larger and the picture is getting clearer. Therefore, it was also questioned whether it is necessary to upgrade the clearer 8K today: the art of broadcasting and TV is not equal to the "scientific experiment microscope."

On this issue, the broadcasting and television industry's answer will be a great "industrial span." On the one hand, with the diversification of the media, especially the popularity of the mobile phone mobile media screen, the television screen of the Radio and Television Department has experienced a crisis of "self-worth recognition."

Do people still have the necessary and interest to watch TV? The answer to this question depends on how much differentiating effects color energy offers compared to the convenience of a mobile phone. The answer to the latter is undoubtedly the big screen + super clear. In other words, a video signal with a higher resolution than a mobile phone and relying on the bandwidth advantage of a wired network transmits a video signal with a higher information density, and is displayed on a more beautiful large screen. This is a basic application scenario that the color TV sets for its future survival.

For the 8K standard, its content is not only a resolution of 7,680 × 4,320 pixels, but also includes a 12-bit color depth, a wide color gamut of the Rec.2020 standard, a progressive scan of 120 frames per second, and 22.2 channels. Sound effects. These standards are designed to systematically maintain the advantages of color TV versus other personal and home "screens."

On the other hand, 8K resolution, and possibly higher levels of technology in the future, also means that the technology on the "screen" can move forward. The industry believes that the 3D stereoscopic display effect of color TVs in the future is still a proposition that cannot bypass the past. Although in the glasses type 3D TV, the market has basically failed. However, consumer acceptance of holographic and stereoscopic stereotypes has not changed - in fact, it is the non-convenient, uncomfortable and unsatisfactory effects of spectacles 3D that have caused the current market for 3D TVs to shrink.

Based on a higher resolution grating diffraction screen technology, it is possible to provide a naked eye holographic 3D effect. And the level of performance of the effect of this technology is directly related to the number of available resolutions. From this point of view, higher resolution is the basis for the upgrade of TV technology and display effects in the future. Among them, 8K may be just a staged goal.

Therefore, from a macro perspective, the broadcasting and TV industry needs 8K, or even higher resolution, and a display effect based on this. This not only means that the picture is clearer, but also means that the future of the broadcasting and TV industry will be more extensive.

The value of consumers, 8K also need price blessing

The world's first consumer-grade 8K TV Sharp despise the AQUOS LCD-70SX970A for a price of 68,888 yuan. Seeing this price, consumers are inevitably afraid. The 8K 70-inch is almost as much as 8 times the price of an ordinary 70-inch.

From the perspective of improving the effectiveness of the 8K, it is equivalent to four 4Ks, and there is no huge gap between the current price differences. Therefore, market participants believe that price will become the biggest obstacle to the spread of 8K products.

In fact, although the content is the biggest industry shortcoming that restricts the 8K display effect, the history of color TV has always been the pace of the whole machine's leading content: the digital age is, the sofa butler, and the whole sofa butler is also the same, today it has become highly popularized. 4K products are also highly advanced in the production of 4K content. That is, consumer TVs have the lead in terminal hardware - as long as the price is right, consumers must be more willing to choose new standards of products.

In this regard, the industry believes that "capacity" is still the biggest bottleneck in cost reduction. Because of the popularization of 8K, the large size above 65 inches is preferred. At present, the 8.5-generation line that is widely used in the color TV industry can only cut three 65-inch panels, and there are a large amount of leftovers, and the efficiency of glass substrates is only 60%. That is, there is no production line suitable for cutting large-size color TV panels, and there is no premise for the large-scale popularization of 8K. This is the reason why Hon Hai has closely linked the Guangzhou 10.5 line with the 8K concept.

At present, the 10.5-generation line of BOE Hefei has entered the equipment installation phase. The two lines of Hon Hai Guangzhou and Huaxing Shenzhen are under construction. Hon Hai USA and BOE Wuhan are planning. In 2018, with the commencement of production of the BOE Hefei project, 65-inch and 75-inch products can be manufactured economically, and 8K products will also enter the new stage of a continuous positive feedback cycle of “scale manufacturing—decline in product costs—market sales increase”.

Beginning in 2018, there will be a 10.5 line commissioned almost every year, and this trend will continue until at least 2022. This will become the basis for the popularity of "large size + 8K" color TV products. This industry process is also sufficient to support the use of 8K color TVs by some consumers in the 2020 Tokyo Olympic Games and the 2022 Beijing Winter Olympics.

In short, 8K color TV is no longer a "concept in dreams," but is a building that is being constructed step by step. We only need to wait for the arrival of the new 8K era.
