However, this TV is priced at 16 million yen, or about 970,000 yuan. The high selling price makes it difficult for Sharp 8K TVs to enter the consumer market. What's worse, there are only a few 8K video resources on the Internet.
In other words, if you are a local tyrant, you have spent nearly 1 million yuan and bought a sharp 8K TV. After returning home, you find that no 8K video can be played!
As the world's first hardware manufacturer to develop 8K TVs, Sharp's technical strength naturally goes without saying. In order to solve the embarrassing situation that no 8K video is available for playback, Sharp has also developed a new technology called "Quattron PRO". This magical technology can achieve 8K picture quality through special pixel algorithms. 
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. 
Simply put, when you use Sharp 8K TV to watch 4K video, the system will add 4K video to 8K video according to the interpolation algorithm.
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. 
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.
Decryption: How Sharp Changed 4K TVs to 8k in One Second
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 impressive.
