Pixel control of the pixel control rate refers to the minimum imaging unit display (pixels) is not working properly (uncontrolled) proportion. The pixel control has two modes: one blind spot, which is the blind spot, at the time that it does not need bright light, called the blind spot; the second is often the highlights of Wuhan led outdoor full color display, when the need does not shine Rather, it has been lit, called often highlights. In general, the composition of the pixels are 2R1G1B (2 颗 red, one green and one blue light, following the same token), 1R1G1B, 2R1G, 3R6G so on, and out of control is generally not the same pixels in the red, green, and blue light all out of control at the same time led full color display, but as long as a lamp out of control, we consider this pixel that is out of control. For simplicity, the pixels of each color (red, green, and blue) were out of control pixel statistics and calculations, take the highest value as we press LED display screen control rate. Identification of brightness level of the brightness level is to identify the human eye can distinguish between images from the black to the white brightness level. Mentioned some of the gray scale is high, it can reach 256 or even 1024. However, due to the sensitivity of the human eye to brightness limited Wuhan led full color display screen and can not completely identify these gradations. That may be a lot adjacent to the gray level of the human eye looks the same. And the eyes ability to distinguish different person. For display, the human eye to identify the level of naturally better, because after all, the image display posters. The human eye can distinguish the brightness level, the greater meaning of the display color space, showing rich colors of the greater potential. Identification of brightness level can use special software to test, generally more than 20 display can even be a good grade.
