Meanwhile, a compensation circuit is used to drive two pixels(P1, P2), and two adjacent pixels(P1, P2) share a plurality of signal lines, thus reducing the number of signal lines for the pixel circuits in a display apparatus, decreasing the pixel pitch, and increasing the pixel density.

    Abstract: There is disclosed a shift register, a gate integrated driving circuit and a display screen. In the shift register, a connection point between the source of the first thin film transistor (T1) and the drain of the second thin film transistor (T2) is set as the first pulling-up node (PU1), a connection point between the capacitor (C1) and the gate of the third thin film transistor (T3) is set as the second pulling-up node (PU2), and the leakage-proof module is added between the first pulling-up node (PU1) and the second pulling-up node (PU2). The leakage-proof module is configured to, under the control of the display control signal terminal (CTI): conduct the path between the first pulling-up node (PU1) and the second pulling-up node (PU2) during the display period in a frame, so that the shift register can output a normal gate-on signal; and disconnect the path between the first pulling-up node (PU1) and the second pulling-up node (PU2) during the touch period in the frame, which is equivalent to connecting a resistor having a large resistance in a discharging path of the capacitor (C1) in series, so that the discharging of the capacitor (C1) can be slowed greatly, and a leakage speed of the capacitor (C1) is decreased effectively, which avoids a problem of abnormal displaying occurs possibly in an application of a touch screen with a high reporting rate.
