Abstract

The invention discloses a square wave angle cutting circuit and a display panel. The square wave angle cutting circuit comprises a first power supply signal access end; a second power supply signal access end; the driving module is respectively connected with the first power supply signal access end, the first node, the output node, the first control signal access end and the second control signal access end; the control module is respectively connected with the first node and the second power supply signal access end; wherein the control module is used for controlling the output node to output a chamfering signal based on the current between the control module and the second power supply signal access end. According to the invention, the control module controls the output node to output the chamfering signal based on the current between the control module and the second power signal access end, so that the voltage output by the output node has a slowly-decreasing gradient, and the problem that the voltage drop value of the driving voltage of the display panel is large is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a square wave clipping circuit and a display panel. Background technique [0002] With the development of display technology, the display panel adopts the gate driving circuit to complete the function of progressive scanning, which reduces the production cost of the display panel and also meets the requirements of the narrow frame of the display panel. However, the square wave drive signal output by the gate drive circuit has a process of high and low level switching. When the gate scan signal changes from high level to low level, the square wave drive signal output by the gate drive circuit will also change from high level to high level. The drive voltage of the display panel also drops sharply from a high level to a low level instantaneously. Bad phenomena such as flicker and afterimage seriously affect the quality of the picture displayed on the display panel....
