Abstract

The invention provides a GOA drive circuit, a display panel and a display device. The GOA drive circuit comprises multiple stages of cascaded GOA circuits, wherein each stage of GOA circuit comprises a GOA circuit unit and a signal splitting circuit which are connected, the signal splitting circuit is connected with two adjacent scanning lines in the display panel, the GOA circuit units work according to original GOA circuit units, an output line scanning signal is used as an input signal of a next-stage GOA circuit unit and a reset signal of a previous-stage GOA circuit unit, and meanwhile, the signal splitting circuit splits the line scanning signal output by the current stage and outputs a first sub-line scanning signal and a second sub-line scanning signal. Thus, scanning driving of two lines of pixel units is realized, the number of devices of the GOA circuit units is reduced, the frame of the display panel is saved, and edge narrowing of the display panel is achieved.

Description

technical field [0001] The present application belongs to the technical field of display panels, and in particular relates to a GOA driving circuit, 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. In the display panel, the GOA (Gate On Array, array substrate row drive) technology refers to the gate drive circuit (Gatedriver IC) is directly fabricated on the array (Array) substrate, and the gate is implemented row by row by outputting row scanning signals. scanning. GOA technology is one of the main technologies to realize the narrow frame of the display panel. On this basis, in order to further narrow the frame of the panel, the number of signals or devices of the GOA circuit is usually reduced. Usually, a GOA circuit unit receives a Clock signal and outputs a cycle of the Clock signal as the scanning signal ...
