Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] 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, and the transistors used in the embodiments of the present invention are mainly switching transistors according to their functions in circuits. 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 called the first pole, the drain is called the second pole, and the gate is called the third pole. According to the form in the accompanying drawings, it is stipulated that the middle terminal of the transistor is the gate, the signal inp...

Abstract

The invention discloses a shifting register unit, a driving method, a grid drive circuit and a display device, and belongs to the technical field of display. The shifting register unit comprises an output control module and an output module, and further comprises two clock control modules. Due to the two clock control modules, clock signals of different frequencies or different duty ratios can be output to the output control module and the output module, the output module can output drive signals of different frequencies or different duty ratios to a pixel unit through the output end, and then the charging time of each row of pixel units can be adjusted; accordingly, the driving modes of the grid drive circuit for the display device are enriched, the drive flexibility is improved, and the display device is used for displaying images.

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] When displaying an image, the display device needs to use a gate driver circuit (English: Gate Driver on Array; GOA for short) to drive the pixel unit. The gate driver circuit (also called a shift register) includes multiple cascaded shift registers. A register unit, wherein each shift register unit is used to drive a row of pixel units, and a plurality of shift register units realizes row-by-row scan driving of the pixel units of the display device to display images. [0003] In the related art, the gate driving circuit can scan each row of pixel units in the display device within one frame, wherein the scanning time for each row of pixel units is determined by the frequency of the clock signal. [0004] Since the frequency of the clock signal output by the clock...
