Problems solved by technology

As mentioned above, since the scan pulse itself is also used as the driving signal of the next-stage shift register unit, such chamfering will reduce the driving ability of the scan pulse to the next-stage shift register unit.

Abstract

The invention provides a shift register unit, a gate drive circuit and a drive method thereof and a display device. The shift register unit is provided with two output modules which output corresponding scanning pulses through different scanning pulse output ends so that the other scanning pulse can still be used to drive the next shift register unit even one of the scanning pulses is set as the scanning pulse with a cutting angle, and thus the driving capacity for the next shift register unit is not reduced. Besides, two input modules are arranged so that the process of scanning pulse outputting of the two output modules is not mutually influenced, the influence of one of the scanning pulses with the cutting angle on the other scanning pulse can be further avoided, and thus the influence on the driving capacity for the next shift register unit can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a gate drive circuit and a drive method thereof, and a display device. Background technique [0002] GOA (Gate Driver On Array, the gate driver circuit is integrated on the array substrate) is an important means to realize the narrowing of the display device. Generally, the gate drive circuit integrated on the array substrate is composed of multi-stage shift register units, and each stage of shift register units sequentially outputs scan pulses to the On the corresponding gate line, each thin film transistor connected to each gate line is turned on, so as to realize the driving process of the corresponding pixel unit; and the scan pulse output by the shift register unit of this stage will also be output to the next stage In the shift register unit, the driving of the next stage shift register unit is realized. [0003] On the other hand, the TFT gate dro...
