Abstract

The invention discloses a shift register unit, a driving method, a grid driving circuit and a display device, belonging to the field of display technology. The shift register unit includes: a clock control module, an output control module and an output module; the shift register unit can output clock signals of different frequencies or different duty ratios to the output control module and the output module respectively through the clock control module , so that the output module can output driving signals of different frequencies or different duty ratios to the pixel units through the output terminal, so as to adjust the charging time of the shift register unit for each row of pixel units, thus enriching the gate driving circuit for display The drive mode of the device improves the flexibility of the drive. The invention is used to display 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 charging time for each row of pixel units is determined by the frequency of the clock signal. [0004] Since the frequency and duty cycle of the clock signal outp...
