Abstract

The invention discloses a square wave chamfering circuit and a drive method thereof and a display panel. The circuit comprises an input module, an output module , a chamfering control module, a chamfering module and a capacitor module, square wave signals input into the signal input end can form signals in chamfering wave shapes when output to the signal output end through the coordination of the five modules, thus the output signals are changed from rectangular sudden change to slope slow descent, accordingly the adverse influences brought by electrical level sudden change when the square wave signals are changed from a high electrical level to a low electrical level can be reduced, and in this way, when the square wave chamfering circuit is applied to the display panel, the quality of displayed pictures can be improved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a square-wave angle-cutting circuit, a driving method thereof, and a display panel. Background technique

[0002] Display panels in the prior art generally display in a progressive scanning manner, that is, within a frame time, when pixels in the Nth row are turned on, other rows are turned off. When a row is turned on, the data signal charges all the pixels in the row. After the charging is completed, the next row is turned on and the row is turned off, and the row maintains the data signal until the scanning of one frame is completed.

[0003] With the development of display technology, display panels use gate drive circuits instead of gate drive chips to complete the progressive scan function, that is, by combining switching transistors and capacitors to form a gate drive circuit to complete the progressive scan function, reducing the The production cost of the display panel...
