Document Type and Number:
WIPO Patent Application WO/2019/157842
Kind Code:
A1
Abstract:
A shift register unit (10), a gate driving circuit (20), a display device (1), and a driving method. The shift register unit (10) comprises a display sub-shift register (200) and a detection sub-shift register (100). The display sub-shift register (200) comprises a display output terminal (OUT2), and the display sub-shift register (200) is configured to output, during a display stage, a display output signal of the shift register unit (10) from the display output terminal (OUT2); and the detection sub-shift register (100) is connected to the display output terminal (OUT2) of the display sub-shift register (200) to receive the display output signal, and comprises a first random pulse signal terminal (OE1) to receive a first random pulse signal. The detection sub-shift register (100) is configured to include outputting a detection output signal of the shift register unit (10) when the display output signal is at the turn-on level and the first random pulse signal is at the turn-on level. The shift register unit (10) can eliminate scan lines appearing in a display process and solve the problem of luminance disparity in a display panel.
