  • DISPLAY DRIVER AND CONTROL METHOD THEREOF
    Publication number: 20240096289
    Abstract: The disclosure provides a control method of a display driver. The control method includes receiving address information and defining an IC address according to the address information. The IC address includes n bits representing k zones, and n and k are positive integers. The control method further includes receiving the IC address, a black frame data signal and a pulse-width modulation (PWM) signal, and turning on or off the plurality of LEDs in the corresponding zone according to toggle of bit in the black frame data signal. Each bit in the black frame data signal indicates that a plurality of LEDs in a zone among the k zones are turned on or off.
