Sharp Pushes 4K Four-Color TV Technology: Picture Sharpness Will Be Close to 8K

It is understood that Sharp 4K four-color technology is based on the 4K panel to upgrade the four-color sub-pixels, it uses four-color filter, based on the red, green and blue colors added to the yellow, to achieve a broader color gamut, Can be more vivid vivid images.

According to a long-term study by Sharp, the definition of the LCD panel is not determined by the number of pixels, but by the number of luminance information. Sharp 4K four-color technology used this formally. The human eye has high visual sensitivity to green or yellow and other colors. According to this physiological characteristic of the human eye, the traditional three-primary panel has only one pixel of green information in one pixel. That is a sharpness. The four-color technology adds yellow to the traditional three primary colors and realizes two brightness information of green and yellow in one pixel, and the resolution is increased by 2 times. As a result, 4K four-color technology has 4 brightness information in 1 pixel, which is 4 times better than 4K TV.

Through the above research results, it can be found that after the four-color technology is mounted on the 4K panel, the screen can be made clearer, and the brightness of the image can be improved by a multiple of the number of luminance information, and finally the clearness of the screen is comparable to the sharpness of 8K (7680×4320), reaching the human eye. The highest pixel value that can be resolved.

The new TV launched by Sharp includes multiple categories, including the new flagship TV with 4K panel, Android smart system and 4K four-color technology, and 40-inch to 65-inch universal 4K smart TV. It will be displayed at the 2015 China Household Appliances Expo (AWE2015).
