The invention discloses a display panel and a display device. The display panel comprises a pixel circuit and a light-emitting element. The pixel circuit comprises a driving module, a compensation module, a first reset module and a leakage current offset module. The driving module is used for providing driving current for the light-emitting element and comprises a driving transistor; the compensation module is used for compensating the threshold voltage of the driving transistor; the first reset module is used for providing a reset signal for the grid electrode of the driving transistor; the leakage current counteracting module is used for changing the grid potential of the driving transistor towards a first direction, leakage current of the compensation module and the first reset module enables the grid potential of the driving transistor to change towards a second direction, and the first direction is opposite to the second direction. According to the embodiment of the invention, the problem that the display panel is easy to flicker in a low-frequency mode can be solved.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, variable frequency drive technology is gradually applied to display panels. For example, a drive method with a high refresh frequency is used to drive the display of dynamic pictures (such as sports events or game scenes) to ensure the fluency of the display picture; the refresh rate is adopted. A lower driving method is used to drive the slow-motion image or static image to reduce power consumption. However, in low frequency mode, the display panel is more prone to flickering problems. SUMMARY OF THE INVENTION [0003] The present application provides a display panel and a display device to solve the problem that the display panel is prone to flicker in a low frequency mode. [0004] In a first aspect, an embodiment of the present application provid...
