Title: SHIFT REGISTER UNIT AND GATE SCAN CIRCUIT
Abstract:
Provided are a shift register unit and a gate scan circuit (GOA). In the shift register unit, when a first scan pulse input terminal (INPUT) is at a first level, a voltage of a first node (N1) is pulled up by a first DC voltage terminal (CN) to realize forward scanning; when a second scan pulse input terminal (RESET) is at the first level, the voltage of the first node (N1) is pulled up by a second DC voltage terminal (CNB) to realize reverse scanning, such that the shift register can support bidirectional scanning of a gate line. In addition, each stage of the shift register unit further has two scan pulse output terminals (OUTPUT1, OUTPUT2). In a subsequent period when the first scan pulse output terminal (OUTPUT1) outputs a gate driving signal to the Nth pixel unit, the second scan pulse output terminal (OUTPUT2) can output a gate voltage to the (N+1)th row of pixel units, such that shift registers at a same stage control two rows of pixels to be turned on.
