Title:
SHIFT REGISTER UNIT, DRIVE METHOD, DRIVE CIRCUIT, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/082719
Kind Code:
A1
Abstract:
Provided are a shift register unit, drive method, drive circuit, and display apparatus. The shift register unit comprises a first node potential adjustment circuit (11), a first energy storage circuit (12), a second node control circuit (13), a second energy storage circuit (14), a third node control circuit (15), a first node control circuit (16), and an output circuit (17); under the control of the potential of the first node (N1), the first node potential adjustment circuit (11) changes the potential of the first node (N1) according to an adjusted clock signal (CK); the first energy storage circuit (12) is used for maintaining the potential of the first node (N1); the third node control circuit (15) controls the potential of a third partitioned node (N03) and the potential of a fourth node (N4); the second node control circuit (13) controls the potential of a second partitioned node (N02). The shift register can provide a gate drive signal and can also provide a light emission control signal, so as to provide a waveform for pixel-specific operation.
