Example Embodiment

[0048] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. According to the function in the circuit, the transistors used in the embodiments of the present invention are mainly switching transistors. Since the source and drain of the switching transistor used here are symmetrical, the source and drain are interchangeable. In the embodiment of the present invention, the source is referred to as the first electrode and the drain is referred to as the second electrode. According to the form in the figure, it is stipulated that the middle end of the transistor is the gate, the signal input end is the source, and the signal out...

Abstract

The present invention discloses a shifting register unit and a drive method thereof, a gate drive circuit and a display device, belonging to the technical field of display. An input control circuit ofthe shifting register unit is connected with a first input signal end, a second input signal end and a first control node, the first input signals end is connected with a first output end of an upper-level shifting register unit, and the second input signal end is connected with a second output end of the upper-level shifting register unit. The shifting register unit can control a first control node potential under the control of the first output end and the second output end of the upper-level shifting register unit, signals output by the first output end of the upper-level shifting registerunit is first clock signals, signals output by the second output end are second clock signals, so the timing sequence of the first clock signals and the second clock signals of the upper-level shifting register unit are flexibly regulated to control the first control node of the shifting register unit, and the work flexibility is high.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] With the development of display technology, in order to ensure the normal operation of the display device, the pixel circuit may include a switching transistor, a driving transistor and a detection module. Wherein, the detection module can be used to detect the voltage of the light emitting device, and compensate the threshold voltage Vth of the driving transistor according to the detected voltage. Correspondingly, two gate lines need to be set to control the operation of the switching transistor and the detection module respectively. [0003] In the related art, each shift register unit may include an input circuit, an output circuit and a pull-down circuit. Since the pixel circuit needs to be provided with two gate lines, each shift register unit needs to be pr...
