The present invention discloses a display panel and a display device. The display panel comprises a plurality of common electrode blocks and a plurality of display regions. During a display period, one or more common electrode blocks corresponding to one of the display regions which is to be displayed during the display period are coupled to a common voltage; and during the display period, one or more of the common electrode blocks corresponding to the display regions which are not to be displayed during the display period are kept in a floating state.

Display panel, display device and driving method

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.
