Abstract

The invention provides a shift register unit, a signal generation unit circuit, a driving method and a display device. The shift register unit comprises a first node control circuit, a second node control circuit and an output circuit. The first node control circuit is used for controlling the potential of a first node. A second node control circuit controls the potential of the second node; and the output circuit is used for controlling and maintaining the potential of the first node and the potential of the second node, controlling the output end to be communicated with the second clock signal end under the control of the potential of the first node, and controlling the output end to be communicated with the second voltage end under the control of the potential of the second node. According to the invention, multi-pulse signals can be output, and the pulse number and the pulse width can be adjusted so as to correspond to threshold voltage compensation time required by different internal compensation circuits.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit, a signal generating unit circuit, a driving method and a display device. Background technique [0002] In the display field, gate drive circuits are used to replace gate drive signals to reduce costs. Since the complexity of the gate drive circuit determines the frame of the display panel and the yield rate of the display panel, a simple gate drive circuit is very important. However, for the pixel compensation circuit inside the display panel, it usually takes a lot of line time to compensate the threshold voltage shift, so a circuit capable of outputting multi-pulse signals is required, and the number of control pulses and pulse widths need to be adjustable, but for traditional gate It is very complicated for the driving circuit to realize this waveform. Contents of the invention [0003] The main purpose of the present invention is to provide...
