On the one hand, the current user is no longer satisfied with the image effects in 4K, for example, more camera technology has reached 8K resolution; on the other hand, the 8K price is too expensive, the video source is too small, even if you buy it back, you should not enjoy it. Some visual experience.
But for the pursuit of new technologies, tireless manufacturers still decisively regard 8K or even higher resolution as their unchanging goal.
Last year, Sharp officially released the 8K TV LV-85001, which has a resolution of 76,804,320 pixels, which is 16 times that of 1080P. The effect is extremely alarming, but the price is as high as 16 million yen (approximately RMB 970,000 yuan) and it is difficult to reach the consumer market. universal. Based on this situation, Sharp has developed a "4K Next" standard, which is equipped with a 4K panel and uses a special pixel algorithm to achieve 8K image quality.
In short, this new technology that allows 4K TVs to change to 8K TVs is to achieve 8K image quality through special pixel algorithms, while Sharp calls its own new technology called “Quattron PROâ€.
Quattron PRO promotes traditional three-color RGB pixels to four-color RGBY (ie, red, green, and blue) for better color performance. At the same time, two sub-pixels are added in each pixel, the brightness of the image is doubled, and there are more actual display pixels (66 million), which is naturally more clear than the conventional 4K 42 million pixels.
It is worth mentioning that although 4K achieves 8K image quality through the algorithm, the price is not cheap, because Sharp has an LC-80XU30 TV that supports the "Quattron PRO" technology, and the price still reaches 110,000.
summary:
Although people in the industry have been discussing the issue that the human eye is basically unable to appreciate the resolution above 4K level, but before the advance history of 1080p to 4K, many people argued that 4K ultra high definition television is a kind of “stupid†idea. At that time, many people in the industry had also proved through scientific perspective that the human eye could not discern the difference between Ultra HD and 1080p HD. Similarly, today's 4K to 8K, whether it is controversy or not, it is the development of screen technology beyond humanity. The next step in identifying the limits of the naked eye.
