SHIFT REGISTER, GATE INTEGRATED DRIVE CIRCUIT, AND DISPLAY SCREEN

摘要

Disclosed are a shift register, a gate integrated drive circuit, and a display screen. In the shift register, a connection point between a source of a first thin film transistor (T1) and a drain of a second thin film transistor (T2) is set as a first pull-up node (PU1), a connection point between a capacitor (C1) and a gate of a third thin film transistor (T3) is set as a second pull-up node (PU2), and an electric leakage prevention module is added between the first pull-up node (PU1) and the second pull-up node (PU2). By means of the module under the control of a display control signal end, the first pull-up node (PU1) and the second pull-up node (PU2) are connected in a display time period of a frame so that a gate-on signal can be normally output by the shift register; the first pull-up node (PU1) and the second pull-up node (PU2) are disconnected in a touch control time period of the frame, which is equivalent to that a resistor with large resistance is connected to a discharge path of the capacitor (C1) in series, and therefore the discharge time of the capacitor can be greatly shortened, the electric leakage speed of the capacitor is effectively decreased, and the problem that normal display may not be achieved when the capacitor is applied to a touch screen with high report rate is solved.
