One of the biggest features of the LED driver chip is to provide a constant current source. The constant current source can ensure the stable drive of the LED and eliminate the blinking phenomenon of the LED, which is the premise for the LED display to display high-quality pictures. In this regard, ETEK has developed a number of series of LED constant current drive circuits suitable for a variety of display effects, suitable for atmosphere lights, electric bicycle, small household appliances, white electricity and other display panels. Customers can select the appropriate display driver chip according to the actual application scenario.
