Title:
SHIFT REGISTER, GOA CIRCUIT, DISPLAY DEVICE, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/176791
Kind Code:
A1
Abstract:
A shift register, a GOA circuit, a display device, and a driving method. The shift register comprises: at least one input module (1) used for charging a pull-up (PU) node under the control of an inputted input signal; at least one output module (2) used for outputting corresponding clock signals by means of corresponding signal output ends (OUT1, OUT2) under the control of the potential of the PU node; a first reset module (3) used for pulling down the potentials of the corresponding signal output ends (OUT1, OUT2) to a reference potential under the control of the potential of a pull-down (PD) node; a first noise reduction module (4) used for performing noise reduction on the PU node by means of a signal inputted by a reference potential terminal (VGL) under the control of the potential of the PD node; a second noise reduction module (5) used for performing noise reduction on the PD node by means of the signal inputted by the reference potential terminal (VGL) under the control of the signals outputted by the signal output ends (OUT1, OUT2) and the potential of the PU node; and a second reset module (6) used for controlling the potential of the PD node under the control of a signal inputted by a reset clock signal input end (CK4).
