Abstract

The invention discloses a display panel, a driving method thereof, and a display device; when the display panel normally displays, each shift register unit inputs a scanning signal to a corresponding grid line in sequence in time sharing, thus realizing line-by-line scanning of the display panel; a reset register unit outputs a signal to a self-reset signal end, thus stopping outputting; in a power off moment, each shift register unit respectively inputs a scanning signal to the corresponding grid line, thus fully opening all pixels of the display panel; the reset register unit simultaneously inputs a control signal to a control end of a switch unit, so the switch unit is conducted, thus conducting each data line with a common electrode, and instantly discharging charges of all pixels to the common electrode, i.e., the display panel can realize inner self-discharging at the power off moment, thus ensuring complete discharging of the pixels, and effectively improving adverse phenomenon like display panel shutdown mura and power on screen scintillations.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] As we all know, flat-panel displays have many advantages that other displays cannot match, such as low power consumption, small size, light weight, and ultra-thin screen. [0003] However, the existing flat-panel displays generally have the problem of slow or even incomplete discharge after shutdown, that is, the pixels of the flat-panel display cannot be completely discharged at the moment of shutdown, which will cause after-images when the flat-panel display is turned off, and the screen will appear again when the flat-panel display is turned on. Flickering and other defects. [0004] Therefore, how to improve the adverse phenomena of power-off afterimage and power-on screen flickering in the display device is a technical problem to be solved urgently by those skilled in the ...
