Product Details

With the development of technology, the connection and use of LCD screens and related devices such as computers have become a necessity. For the convenience of application in various occasions, the application of LCD screens is divided into synchronous and asynchronous, data synchronous and asynchronous, hence the name meaning: data synchronous refers to the real-time communication between the control device and the LCD screen, while asynchronous refers to the independent operation of the control system and the full-color LED LCD screen. Based on the commonly used data synchronization display method, the following will introduce the data synchronization display. 1、 The overall design of the system hardware is divided into three parts. Firstly, the VGA monochrome digital video signal, pixel clock, row data synchronization, and frame synchronization are extracted in real-time from the independent graphics card through the display information extraction circuit. After processing, they are transmitted through the output medium; The second part is the CRT video signal to signal conversion circuit, which selects, stores, reads, and distributes the image signal transmitted from the transmission medium, and converts it into a display signal corresponding to the LED dot matrix screen; The third part is the LED driver board, which receives the converted LED display signal and assigns it to the corresponding pixel points of the LED dot matrix screen to drive the LED display.
