The grayscale of LED display is one of the important parameters of LED display. The grayscale of LED display is the color scale or grayscale of LED, which refers to the brightness of LED display. The grayscale level of LED display refers to the brightness level that can be distinguished from the darkest to the brightest in the same level of brightness of LED display.
The grayscale level of LED display determines the color of LED display. Generally speaking, the higher the grayscale, the richer the color displayed, the more delicate the picture, and the easier it is to show rich details.
The grayscale of LED display has grayscale, 8 levels, 16 levels, 32 levels, 64 levels, 128 levels, 256 levels, 1024 levels, etc. Domestic LED display mainly adopts 8-bit processing system, and international brand LED display mainly adopts 10-bit processing system.
1. 8-bit processing system, that is, 256 (2 to the 8th power) grayscale, simply understand that there are 256 brightness changes from black to white.
2. 10-bit processing system, that is, 1024 (2 to the 10th power) grayscale levels, which means that there are 1024 brightness changes from black to white.
3. 12-bit processing system, that is, 4096 (2 to the 12th power) grayscale levels, which means that there are 4096 brightness changes from black to white.
4. 14-bit processing system, that is, 16384 (2 to the 14th power) grayscale levels, which means that there are 16384 brightness changes from black to white.
Although grayscale is the determining factor for the number of colors, it does not mean that the larger the better, because the resolution of the human eye is limited. Moreover, the increase in the number of system processing bits will involve changes in various aspects of the system video processing, storage, transmission, scanning, etc., and the cost will increase dramatically, but the cost performance will decrease. Generally speaking, civilian or commercial products can use 8-bit systems, and broadcast products can use 10-bit systems.
