Abstract: The present disclosure provides a method for a display driver system and a display driver system. The method comprises: the control circuit transmitting a global signal and a first signal for a LED driver circuit in each stage to a first-stage LED driver circuit, wherein the global signal includes an command for indicating an operation mode of the LED driver circuit in each stage; the LED driver circuit in each stage determining the operation mode corresponding to the command according to the global signal, identifying a corresponding first signal of the LED driver circuit in the stage, and operating according to the determined operation mode and the corresponding first signal; and the LED driver circuit in each stage except for last stage transmitting the global signal to the LED driver circuit in its next stage, and in response to a completion of operation according to the determined operation mode and the corresponding first signal, transmitting the first signal for the LED driver circuit in each of sequential stages to the LED driver circuit in its next stage.
