Millet TV Team: CESI certified Millet TV 2 Why is the real 4K screen

Millet TV 2 has been officially released, the product of a prominent feature is the use of the world's top LCD 4K screen, and 4K is the future of television technology mainstream trend. The Millet TV 2 uses the LG and huaxing photoelectric high-quality 4K screen, the sharpness is 4 times times of the previous generation 1080p. But do you know why the Millet TV 2 is RGB true 4K screen? Now we are in the spirit of scientific knowledge, together to understand the Millet TV 2 and 4K screen of those knowledge. 1. The Millet TV 2 generation LG screen Millet TV 2 generation uses LG's OC model is LC490EQJ-SGK1, this display screen's pixel size is 0.27963*0.27963mm, the display area size 1073.78*604.00mm, the physical resolution is 3840*rgb* 2160. To be more certain, we actually took the millet TV with a magnifying glass. 2-pixel array display photos shown in the following figure, Pixels are rgbrgbrgb arranged. Rather than the so-called pseudo 4KRGBW mode. Also welcomed the broad masses of users in the product after the listing check. 2.RGB and RGBW RGB color mode is a color standard in industry, is through the red (R), Green (G), Blue (B) three color channels and their superposition to get a variety of colors, RGB is the representative of red, green, blue three channels of color, This standard contains almost all the colors that human vision can perceive, and is one of the most widely used color systems. An RGB color value specifies the relative brightness of red, green, and blue primaries to produce a specific color for display. Use the RGB function to calculate a long integer representing a color using the following formula: 65536 *blue + 256 * green+red of which, blue is the color component, and green represents the red component. In each component, the smaller the number, the lower the brightness, the greater the value, the higher the brightness. RGBW in the original RGB three primary colors on the basis of the pixel, and then add a white sub-pixel, forming a RGBW four-color pixel. The purpose is to improve the efficient use of LCD for energy, in RGB color filter to add a white area through the region can improve the LCD on the backlight utilization, increase LCD display brightness, reduce LCD power consumption. One of the biggest problems with this pattern is that the purity and saturation of monochrome are reduced.
