Shifting register, drive method thereof, gate drive device and display device

Abstract

The invention provides a shifting register. The shifting register comprises an input module, a holding module, a selection output module, a first output module, a second output module and a third output module, wherein the input module is configured to be used for controlling voltages of a first node and a second node; the holding module is configured to be used for holding the voltages of the first node and the second node as well as output voltages of the first and second output modules; the selection output module is configured to be used for selecting the first output module and / or the second output module for output of scanning signals and controlling the voltages of a third node and / or a fourth node according to the voltage of the second node; the first output module is configured to be used for outputting a first output signal from the first output end according to the voltages of the first node and the third node; the second output module is configured to be used for outputting a second output signal from the second output end according to the voltages of the first node and the fourth node; the third output module is configured to be used for outputting a third output signal from the third output end according to a second clock signal and the voltage of the second node.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register suitable for folding displays, a driving method thereof, a gate driving device, an array substrate and a display device. Background technique [0002] As display technology develops, foldable displays are becoming more and more popular. In the prior art, the structure of the drive circuit used to drive the foldable display is, for example, as figure 1 structure shown. It uses multiple cascaded traditional shift registers to synchronously send the same scanning signal to the left and right display areas, and controls the opening and closing of the left and right display areas through the control circuit arranged between the shift register and the left and right display areas. closure. Such as figure 1 As shown, the display of the left display area is controlled by control signals S1 and S2, and the display of the right display area is controlled by co...
