Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a shift register unit, a shift register, an array substrate and a display device. Background technique [0002] The application of the organic light emitting diode panel (Active Matrix Organic Light Emitting Diode, referred to as: AMOLED) becomes more and more important. The pixel display device of AMOLED is an organic light-emitting diode (Organic Light-Emitting Diode, hereinafter referred to as OLED). OLED has the advantages of high brightness, wide viewing angle, and fast response, and is widely used in high-performance display panels. AMOLED can emit light through a switch The progressive scanning of the tube drives the thin film transistor to generate a driving current in a saturated state, and the driving current drives the OLED to emit light. The array substrate row driving scanning circuit (Gate On Array, GOA for short) integrates the row driving scanning ...
