Title:
SHIFT REGISTER UNIT, GATE DRIVING CIRCUIT, DISPLAY DEVICE, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/157865
Kind Code:
A1
Abstract:
A shift register unit (10), a gate driving circuit (20), a display device (I), and a driving method (1300, 1400). The shift register unit (10) comprises a blanking input circuit (100), a display input circuit (200), an output circuit (300), and a compensation selection circuit (400). The blanking input circuit (100) is configured to input a blanking input signal to a control node (H), and input the blanking signal to a first node (Q) in a blanking period of one frame; The blanking input circuit (100) is configured to input a blanking input signal to a control node (H), and input the blanking signal to a first node (Q) in a blanking period of one frame; the output circuit (300) is configured to output, under the control of the level of the first node (Q), a composite output signal to an output terminal (OUTPUT); and the compensation selection circuit (400) is electrically connected to the output terminal (OUTPUT), and is configured to charge, in response to the compensation selection control signal, a control node (H) by using the composite output signal. The gate driving circuit (20) configured by the shift register unit (10) can perform random compensation on sub-pixel units of a display panel, avoiding display defects caused by long-time progressive sequential compensation.
