SHIFT REGISTER AND DRIVE METHOD THEREFOR, GATE DRIVE CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/118136
Kind Code:
A1
Abstract:
A shift register and a drive method therefor, a gate drive circuit, and a display device. The shift register comprises a control signal generating module, a first low-level pulse generating module, a second low-level pulse generating module, and a high-level pulse generating module. The control signal generating module is connected to a first clock end (CK1), a second clock end (CK2), a first voltage end (VGH), a second voltage end (VGL), and a first input end (STVG), and generates a first control signal and a second control signal. The first low-level pulse generating module receives the first control signal and the second control signal, and generates a first low-level pulse signal. The second low-level pulse generating module receives the first control signal and the second control signal, and generates a second low-level pulse signal. The high-level pulse generating module is connected with the first clock end (CK1), the first voltage end (VGH), the second voltage end (VGL), and a second input end (STVE), receives the first control signal, and generates a high-level pulse signal. The shift register reduces the number of circuit elements is reduced.
