Abstract

The invention relates to a GOA circuit, a display panel and a display device. The circuit comprises a pull-up module, a pull-up control module, a pull-down maintenance module, a power storage module, a first pull-down module and a second pull-down module, specifically, the first end of the pull-up module is connected with the first end of the pull-up control module, the first end of the pull-down maintenance module and the first end of the power storage module; the second end is connected with the second end of the power storage module and the first end of the first pull-down module, and the third end is connected with the second end of the pull-down maintaining module; the third end of the pull-down maintaining module is connected with the second end of the first pull-down module, the third end is connected with the first end of the second pull-down module, and the fourth end is connected with the second end of the second pull-down module; the third end of the second pull-down module is connected with the first end of the pull-up control module. According to the GOA circuit, wide pulse output can be achieved, meanwhile, the number of TFTs can be reduced, and edge narrowing of display equipment can be achieved.

Description

technical field [0001] The present application relates to the technical field of display driving, in particular to a GOA circuit, a display panel and a display device. Background technique [0002] With the continuous development of display technology, the performance of the display panel is also gradually improved, such as the refresh rate, resolution, lifespan and other performances of the display panel are constantly rising. Among them, the GOA (Gate on Array, grid array) technology in the display panel has great advantages over the COF Gate technology (Chip on film Gate, film-on-chip packaging gate) in terms of cost and functionality, so it is widely used. application. [0003] Among them, the GOA technology required by medium-sized OLED (Organic Light-Emitting Diode, organic light-emitting diode) products uses a wide pulse module, which needs to output a high-voltage signal of tens of microseconds, because the wide pulse module is relatively Complicated, the number of...
