Working principle of LED display
The computer (or a workstation on the network) controls the display of the electronic display. It can run a program written according to the user’s needs, and extract the relevant display data on the local hard disk of the computer or on the network server. Of course, the display effect of the LED screen can also be artificially generated. The pixels on the screen and the pixels on the corresponding area of the screen controller display correspond one-to-one and map directly.
Controlling the computer through the electronic display screen can manually or automatically adjust the brightness, contrast, chromaticity, etc. of the display screen, select the grayscale correction data suitable for the current environment, and control the computer to transmit the information to be displayed to the video signal processor and control unit for video. Information processing.
Video signal processing control system The video processing controller is a set of multimedia video cards specially used on the LED display screen. It is used for image processing of display data. It includes: grayscale adjustment, brightness adjustment, image noise reduction, motion compensation, color coordinates Space transformation, chromaticity adjustment function, mosaic removal, etc.
The video controller can pass the processed display information to the communication module for long distance transmission to the display screen.
The communication system connects the control computer and the display screen through 25 pairs of super five twisted pairs, which effectively ensures that the content displayed on the computer display is transmitted to the display screen for display.
Summary: This article mainly talks about the principle of LED display. Through the understanding of this article, you can understand the LED display more clearly.
