Abstract
A display device and a panel drive circuit thereof, and a method for charge bleed-off are disclosed, relating to the field of display technologies. The panel drive circuit includes a panel control circuit and a display drive circuit. In the case that a display panel is turned off, the panel control circuit transmits at least one of a display drive signal and a charge bleed-off signal sequentially to the display drive circuit before a potential of a power supply signal drops to less than a potential threshold, such that the display drive circuit sequentially performs at least one of controlling the display panel to display a second picture that is monochrome and bleeding off charges in advance.
