Abstract

The invention discloses a GOA circuit and a display panel. The GOA circuit comprises multiple stages of GOA units, the Nth stage of GOA unit only comprises a pull-up control module, a pull-up output module, a pull-down module and a pull-down maintaining module, and the structure is simple. Moreover, the pull-down maintenance module is connected with a clock signal, and the potential of the pull-up node can be pulled down under the control of the clock signal, thereby reducing the number of transistors in the GOA unit. According to the GOA circuit, the working time of the pull-down maintaining module can be shortened, the working life of the pull-down maintaining module is prolonged, and the working stability of the GOA circuit is further improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a GOA circuit and a display panel. Background technique [0002] The gate driver on array (GOA) technology of the array substrate is to integrate the gate driver circuit on the array substrate of the display panel to realize the driving method of progressive scanning. The driving technology can save the gate driver, has the advantages of reducing the production cost and realizing the design of the narrow frame of the panel, and is used for a variety of displays. The GOA circuit usually includes a pull-down maintaining module, and the pull-down maintaining module is always in a working state during the pull-down period, which affects its working life and thus affects the working stability of the GOA circuit. SUMMARY OF THE INVENTION [0003] The present application provides a GOA circuit and a display panel to solve the technical problem that in the existing GOA...
