Title:
GATE DRIVING UNIT, GATE DRIVING METHOD, GATE DRIVING CIRCUIT AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/089067
Kind Code:
A1
Abstract:
A gate driving unit, a gate driving method, a gate driving circuit, and a display apparatus. The gate driving unit comprises a first clock signal terminal, a second clock signal terminal, a third clock signal terminal, a fourth clock signal terminal, a first output node control circuit (11), a second output node control circuit (12), a first control node control circuit (13), and an output circuit (14). The gate driving unit can provide a gate driving signal required by an N-type transistor for a low temperature polycrystalline oxide (LTPO) pixel circuit, and can reduce the number of transistors used to help achieve a narrow bezel.
