Open the outer casing of the LCD display and you will find several boards. One of the larger, more compact boards is the main board of the LCD, usually called the “drive board”. The function of the driver board is to process and control the signal sent from the external host, and then send it to the LCD panel to display the image. Figure 1 shows the physical diagram of the motherboard of a liquid crystal display. The more important integrated circuits on the driver board are the master chip (Sealer chip) and the microcontroller (MCU). The input interface of the driver board is connected to the main control chip of the computer motherboard graphics card through a connection line, and the output interface is connected to the liquid crystal panel through one or two signal transmission cables.
