In the first half of 2020, the domestic market performance of 8K TV is almost four times that of the same period in 2019. However, the absolute number is only 15000 units – but the 8K that will appear at the exhibition and press conference is actually “laboratory pet”, far from becoming a real marketing concept. < / P > < p > in this regard, people in the industry use this sentence to describe 8K: high price in high price, higher end in large screen, luxury in luxury! Indeed, at present, the sales of 65 inch and above large screen TVs are still “the minority in the market”; 8K is “the very few of these few”. Even, laser TV, OLED TV and other new categories, but also “lack of sufficient 8K” layout. On the other hand, 8K products are really expensive. Even the cheap 8K products launched by Changhong and others are more than two or three times the price of 4K TVs of the same size. What’s more, these cheap 8K TVs, which represent 55 inches, don’t work well – they’re too small for high-resolution clarity. Of course, another factor hindering the choice of 8K TV is the “cliche” content problem: the lack of 8K content in the market. Although many 8K TVs claim to be able to convert 4K content to 8K, or even 2K content to 8K image quality, firstly, the difference between the 8K image quality processed by this technology and the 8K original shot is bound to be huge; secondly, even if the 8K content processed by the same technology, the effect of real-time TV conversion is obviously better than the “technology” which takes tens of hours and is generated by professional programs and equipment Conversion “8K” is even worse. Therefore, the conversion of 8K image quality, especially the real-time TV conversion technology, is only a supplement of 8K content. This can not really solve the problem of 8K content fatigue. < / P > < p > at present, the 8K TV sets sold in the market are mainly based on liquid crystal display technology. However, from the perspective of productization, the same size LCD panel changes from 4K to 8K standard, and the effective area of opening ratio performance will be reduced by 40%. The pixel structure of LCD is essentially a frame filled with liquid crystal materials. Under the current material and box forming process, the thickness of this frame can hardly be further reduced for large-size panels. This determines that the area of liquid crystal material that can be used to transmit light on the screen will decrease a lot after the pixel density increases. < / P > < p > the available light transmission area is reduced by 40%, which means that the backlight power is increased by 60%. Therefore, the new version of TV energy efficiency standard has prepared “one version” for 8K TV. The similar principle structure is also suitable for OLED TV products. OLED panel is made by evaporation plating process or ink-jet printing process. Large size and high density will significantly increase the product cost, reduce the yield and reduce the luminous capacity of the unit panel. As a result, not all OLED TVs, which are regarded as high-end, adopt the 8K standard. In fact, the main sales of OLED TVs are still 4K products. < / P > < p > in addition to LCD and OLED TVs, laser TV is another 8K option. In theory, the large size advantage of laser TV is also best suited for 8K applications. Because only large-scale images can really play the advantage of 8K high-resolution resolution. However, 8K laser TV is still far away: due to the projection technology-based laser display, light valve products will also appear technical difficulties or price increases with the increase of resolution. < / P > < p > for projection display such as laser TV, jitter displacement pixel technology can be used to realize 8K application, which has the advantages of the lowest cost and limited technical difficulty, but the effect will also be reduced; another projection 8K technology is “native 8K light valve”, which needs to break through the high pixel density, high opening rate technology and high thermal protection capability, or adopt a larger light valve substrate Either technology means “a huge change in cost.”. < / P > < p > however, under the background that the scale of 8K TV is very limited and the scale of laser TV itself is also very limited, no matter which scheme of laser TV light valve realizes 8K display, it will face a lot of market bottleneck and pressure. < / P > < p > the hot 8K TV technology route also includes micro LED technology. As an active light-emitting display technology, its display effect is excellent. However, as a sub-pixel structure, single LED crystal makes the manufacturing process, efficiency and yield of the display panel relatively high, and has a great relationship with pixel density. 8K micro LED TV often means higher cost and lower technology maturity. < / P > < p > therefore, it is still unknown which display technology should be entrusted to realize the beautiful vision of 8K TV. A variety of technologies are competing. From a good point of view, “a hundred flowers bloom”, and from a bad point of view, it is “lack of a display technology that really has a huge advantage on 8K”. < / P > < p > can you get the shocking effect of 8K display when you buy 8K TV? Many consumers will think “it’s certain.”. But the opposite is true. < / P > < p > first of all, the shock effect of 8K must depend on “bigger screen”. At a certain distance, the human eye’s resolution is limited. For example, the 2.5-3.5-meter “living room sofa TV” distance for conventional TV viewing exceeds the limit resolution of the human eye for a 40 / 50 inch 8K. Just because of this principle, 32 inch TV does not even have the power to achieve 2K popularity. < p > < p > < p > “not too far viewing distance, enough screen image” two requirements are met at the same time, 8K can present an ideal shock picture. In general, however, the viewing distance is proportional to the size of the screen. If the viewing distance should not be too far, it is equivalent to achieving “lower screen output brightness” without damaging the effects of color and contrast, which is a contradictory “technical index” option. < / P > < p > secondly, 8K appreciation means that consumers need a bigger house no matter what the viewing distance and screen image are; at the same time, the higher price of 8K content and the higher price of display products also mean the increase of “cost” – that is, 8K is a “high consumption” product no matter how you look at it. This will inevitably become an obstacle for many consumers to enter the 8K. < / P > < p > in fact, at present, many large home screens, including projection and LCD TV, still watch 2K content, and even the products themselves are 2K products. Consumers’ tolerance for clarity will be higher when the resolution is closer to the limit. 2K home theater products still occupy the mainstream 100 + inch screen market, which is the embodiment of this rule. It is just different from the high-end TV industry to meet the needs of the next generation. < / P > < p > “the market is optimistic about the value of 8K technology. However, this does not mean that the market thinks that 8K will be popularized in the home. 8K can be a special application for engineering and commercial display, a luxury in home TV, or a rental and sharing application market! ” Industry experts pointed out that the 8K display era will not be a complete replacement of the previous HD era, but more likely to be a differentiated structural market and a technical standard equipped on demand. gather and watch!
