Abstract

The application discloses a display panel and a display device. It includes a pixel circuit, the first reset module includes a first double-gate transistor, and the first intermediate node of the first double-gate transistor is electrically connected to the light emission control signal line through a first capacitor; the compensation module includes a second double-gate transistor, and the second double-gate transistor The gate of the transistor is electrically connected to the second scanning signal line, and the second intermediate node of the second double-gate transistor is electrically connected to the light emission control signal line through the second capacitance; wherein, the first double-gate transistor includes a first parasitic capacitance, and the second The double-gate transistor includes a second parasitic capacitance, the first capacitance corresponds to the first parasitic capacitance, the second capacitance corresponds to the second parasitic capacitance, and the capacitance of at least one of the first capacitance and the second capacitance is greater than or equal to its corresponding parasitic capacitance of capacitance. According to the embodiment of the present application, it is possible to solve the problem that the display panel tends to flicker in the low frequency mode.

Description

technical field [0001] The present application relates to the field of display technology, 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, such as using a driving method with a higher refresh rate to drive and display dynamic images (such as sports events or game scenes) to ensure the smoothness of the display screen; A lower driving mode is used to drive and display slow-motion images or static images to reduce power consumption. In low frequency mode, the display panel is more prone to flickering problems. Contents of the invention [0003] The application provides a display panel and a display device to solve the problem that the display panel tends to flicker in low frequency mode. [0004] In the first aspect, the embodiment of the present application provides a display panel, including a pixel circuit, and the ...
