The function of the LCD drive board is to process and control the signal sent by the external host, and then send it to the liquid crystal surface to display the image. The more important integrated circuits on the driver board are the master chip (Sealer chip) and microcontroller (MCU). The input interface of the drive board is connected with the main control chip of the computer motherboard graphics card through the connecting line, and the output interface is connected with the liquid crystal panel through one or two signal transmission lines.

Simply say the drive board is equivalent to a component connecting the host and the display, the host input information through the drive board and then connect the display output through the drive board.
