Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0039] In a first aspect, the present invention provides a shift register unit, see figure 1 , the shift register unit consists of:

[0040] The input unit 110, the output unit 120, the reset unit 130, the first control unit 140 and the second control unit 150, and have a first node N1, a second node N2, a third node N3, a shift signal output terminal OUTPUT and several input; among them,

[0041] The input unit 110 is connected to the first input terminal S1, the second input terminal S2 and the second node N2, and is adapted to set the level of the second node N2 to set as the level input by the second input terminal S2;

[0042] The first control uni...

Abstract

The invention provides a shift register unit and its driving method, gate drive circuit and display device. The shift register unit includes: an input unit, an output unit, a reset unit, a first control unit and a second control unit. And it has a first node, a second node, a third node, a shift signal output terminal and several input terminals. The width of the shift pulse output by the shift register unit can be adjusted by the shift pulse input into the shift register unit, and the output shift pulse signal has the same width as the input shift pulse signal. The width of the pulse signal output by each stage shift register unit in the gate drive circuit obtained by cascading such a shift register unit can be adjusted according to the width of the start signal input to the first stage shift register unit. It is suitable for driving a display device that requires a large shift pulse width.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method thereof, and a gate driving circuit. Background technique [0002] With the continuous development of display technology, high resolution and narrow borders have become the development trend of display devices, and the application of GOA (Gate Driver IC on Array, gate driver IC on array substrate) in display devices is to achieve narrow One of the important methods of border and high resolution. [0003] Existing GOA generally includes multiple cascaded shift register units. In a general shift register unit, a clock signal is connected to the input end of the output unit, and the width of a high-level shift pulse output by the output unit is consistent with the width of a high-level pulse in the clock signal. In this way, when the width of the shift pulse required by the display device is relatively large, the gate drive circuit obtained...
