Abstract

The invention is suitable for the technical field of display, and provides a driving circuit of a display panel and a display device. The driving circuit of the display panel provided by the invention comprises a generation module, an output module and a switch control module, wherein the output module is electrically connected with the generation module and the switch control module; the output module is used for outputting a generation signal to the gate driver according to the switch control signal; the output module is further used for outputting a first clock signal and a second clock signal to the gate driver according to the switch control signal, the refresh rate of the display panel can be changed in real time, the power consumption of the high-refresh-rate display panel is reduced, meanwhile, the signals output by the output module can be continuous, and the power consumption is reduced. Therefore, the display effect of the display panel is improved, and the service life of the display panel is prolonged.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a driving circuit of a display panel and a display device. Background technique [0002] With the rapid development of display technology, display panels are widely used in various fields such as entertainment, education, and security, and users have gradually increased requirements for display effects of display panels. The refresh rate (Frames Per Second, FPS) is an important index to measure the display effect of the display panel. The refresh rate determines the number of frames transmitted per second. The higher the refresh rate, the shorter the time interval of each frame, which can improve The clarity and fluency of the display screen can effectively improve the display effect. [0003] At present, high-refresh-rate display panels have been widely promoted in mid-to-high-end markets, but high-refresh-rate display panels consume relatively high power...
