The main control unit in the display is the core part of the entire display device, which is responsible for processing the input signal and converting it into an image or video that can be displayed on the screen. The master control unit usually consists of a microprocessor (CPU) and graphics processing unit (GPU), etc., which work together to control the rendering of the image, resolution setting, color correction, and communication with other hardware.

In modern displays such as liquid crystal display (LCD), LED or OLED, the master control unit receives the signal from a computer, TV box, game console or other device, decodes it, and passes the image data to the driver circuit of the display panel, ensuring that the pixels are displayed in the correct order, brightness and color. The main control unit is also responsible for the refresh rate adjustment of the screen, brightness and contrast control, and the management of the input and output interfaces to ensure the smoothness and stability of the display effect.

With the progress of technology, the processing power of modern master control units is getting stronger and stronger, not only to support higher resolution (such as 4K, 8K), higher frame rate display, but also to process complex image and video data, making the display effect more fine and real. The master control unit plays a vital role in the proper operation of the display screen and is one of the core components to ensure image quality and user experience.
