The driver chip in the display is the key component responsible for controlling and driving each pixel or display unit on the display panel. Its main function is to receive signals from the master control unit or graphics processing unit (GPU), and convert these signals into voltage or current, activate each pixel on demand, and thus control the image display on the screen.

In liquid crystal display (LCD), organic light-emitting diode display (OLED) and other technologies, the driver chip plays a crucial role. For LCD displays, the driver chip controls the arrangement of liquid crystal molecules, which in turn adjusts the light transmittance, affecting the brightness and contrast of the screen. In the OLED display, the driver chip directly controls the spontaneous light source of each pixel, accurately adjusting the brightness and color of each pixel, thus presenting a more vivid and delicate picture.

In addition, the driver chip is also responsible for the screen's refresh rate control and power management. It ensures that the screen works stably in different display modes, avoiding problems such as image tearing or delay. With the progress of display technology, the performance of the driver chip is also constantly improving, not only supporting higher resolution and refresh rate, but also improving the accuracy and stability of the display effect, becoming one of the core components in modern display technology.
