LED display is currently one of the most widely used large-screen displays in the world. It has a high market share and covers indoor and outdoor large-screen applications. It is very important to understand the relevant knowledge of LED displays. If you are working in this industry , It should be more clearly understood, today we will talk about the gray level of the led display screen.
LED display
Gray scale 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 level, the richer the color displayed, the more delicate the picture, and the easier it is to express rich details.
The gray level mainly depends on the system's A/D conversion bits. 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 screen 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. The three primary colors of RGB can form 256×256×256=16777216 colors. That 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. The cost will increase sharply, and the price/performance ratio will decrease. Generally speaking, civil or commercial grade products can use 8-bit systems, and broadcast grade products can use 10-bit systems.
The above is the professional knowledge of the gray level of the led display. I hope it will be helpful to you in the process of learning the led display. If you need to know more about large-screen technical issues, or have related questions, please feel free to consult
