Abstract

The invention discloses a display panel and a display device. A release control module is arranged, so when the potential of a signal at a release control signal end changes, that is, when the displaypanel is changed from a light-on state to a light-off state, turn-on control signals are output to respective conduction control modules. The conduction control modules and charge release modules arearranged on pixel units, so when the conduction control modules receive the turn-on control signals, driving electrodes and the charge release modules can be conducted so as to output charges on thedriving electrodes to the charge release modules through which the charges on the driving electrodes are released. When the display panel is in the light-on state, the potential of the signal at the release control signal end does not change, so that the release control modules do not output the turn-on control signals. Thus, when the display panel enters the light-off state, the charges left on the driving electrodes in the pixel units are released, and the splash screen problem when the display panel is lit due to DC bias can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] At present, during the use of electronic display products such as mobile phones and tablet computers, it is necessary to light up and turn off the display panel. When the display panel is turned on to display an image picture, it is generally realized by charging the pixels in the display panel. However, when the display panel enters the off-screen state, the switching transistors in the pixels that control the charging are in the off state, thus resulting in the remaining part of the charges used for display in the pixels. Since the residual charge exists for a long time, it will cause a DC bias. When the display panel is turned on again, due to the effect of the DC bias, the display will have a flickering problem.
