What is the role of the driver IC in the LED display

　　As we all know, LED display is a display unit composed of light-emitting diodes and driver chips, and it is a large size flat display that is spliced together. The LED display driver IC is a key component. The performance of driver chip plays an important role in the display quality of LED display screen.

　　The special driver chip for LED display refers to the driver chip specially designed for LED display according to LED luminous characteristics. The maturity of LED display driving IC technology has brought a qualitative leap for the display effect of LED display. With its characteristics of high output current, constant current, etc., LED display can be used in various occasions with high current and high image quality, which directly promotes the development of the form of LED display content and its application field towards a more diversified direction.

　　Function of driving IC: receiving display data (from information sources such as receiving card, sending card or video processor) in accordance with the protocol, internally producing PWM and current time changes, and outputting PWM current related to brightness and grayscale refresh to light LED. The peripheral IC composed of driving IC, logic IC and MOS switch jointly acts on the display function of led display screen and determines its display effect.
