Title:
SHIFT REGISTER UNIT, DRIVING CIRCUIT, DISPLAY APPARATUS, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/191511
Kind Code:
A1
Abstract:
A shift register unit (100), a driving circuit, a display apparatus, and a driving method. The shift register unit (100) comprises a first input circuit (110), a second input circuit (120), an output circuit (130), a first control circuit (140), and a second control circuit (150). The first input circuit (110) is electrically connected to a first node (N1), and is configured to transmit an input signal (IN) to the first node (N1) under the control of a first clock signal (CK1). The second input circuit (120) is electrically connected to the first node (N1) and a second node (N2), and is configured to control the level of the second node (N2) under the control of either the level of the first node (N1) or the first clock signal (CK1). The first control circuit (140) is electrically connected to the second node (N2) and a third node (N3), and is configured to control the level of the third node (N3) under the control of both the level of the second node (N2) and a second clock signal (CK2). The output circuit (130) is electrically connected to the third node (N3) and an output end (OUT), and is configured to output an output signal to the output end (OUT) under the control of the level of the third node (N3). The pulse width of the output signal of the shift register unit (100) is adjustable.
