We often hear that what is the grayscale and brightness of the LED display, so how much do you know about the grayscale and brightness of the LED display?
The gray scale of the LED display screen is the so-called color scale or gray scale, which refers to the degree of brightness. For digital display technology, grayscale is the decisive factor for the number of colors displayed. Generally speaking, the higher the gray scale, the richer the color displayed on the screen, the more delicate the picture, and the easier it is to express rich details.
The gray level of the LED display mainly depends on the number of A/D conversion bits of the system. Of course, the system's video processing chip, memory, and transmission system must provide support for the corresponding number of bits. At present, the domestic LED display mainly adopts an 8-bit processing system, that is, 256 (28) gray levels. The simple understanding is that there are 256 brightness changes from black to white. It can be constituted by using the three primary colors of RGB, which is commonly referred to as 16 mega colors. International brand display screens mainly use a 10-bit processing system, that is, 1024 gray levels, and the three primary colors of RGB can constitute 1.07 billion colors.
Although the gray scale is the decisive factor in determining the number of colors, it does not mean that the larger the limit, the better. Because firstly the resolution of the human eye is limited, and the increase in the number of system processing bits will involve changes in the system's video processing, storage, transmission, scanning and other links, resulting in a sharp increase in cost and a decrease in cost performance. Generally speaking, civil or commercial-grade products can use 8-bit systems, and broadcast-grade products can use 10-bit systems.
