Abstract

The present application is applicable to the field of display technology, and provides a driving circuit and a driving device of a display panel. The driving circuit provided by the embodiment of the present application includes a stretching module, a control module, a bootstrap module, and an output module. The control module is electrically connected to the stretching module, the bootstrap module, and the output module respectively, and the bootstrap module is electrically connected to the output module. The generated widening signal can make the bootstrap module have enough time to charge, and ensure that the output module can reach or exceed the preset potential when receiving the bootstrap signal, so as to avoid voltage instability when outputting the gate drive signal and avoid gate drive signal The phenomenon of stopping the output in advance to improve the stability of the output gate driving signal, thereby improving the display brightness and the stability of the display effect of the display panel while improving the refresh rate and resolution of the display panel.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a driving circuit and a driving device of a display panel. Background technique [0002] With the continuous development of display technology, display panels are widely used in various fields such as entertainment, education, and security. GDL (Gate Driver Less, Array Substrate Row Drive) technology refers to the gate driver IC is directly fabricated on the array (Array) substrate to realize the driving method of progressively scanning the gate. GDL technology can simplify the manufacturing process of the display panel, save the chip bonding (Bonding) process in the direction of the horizontal scanning line, and reduce the production cost. At the same time, it can improve the integration of the display panel and make the display panel lighter and thinner. [0003] At present, users have higher and higher requirements for the refresh rate and resolution of...
