    Abstract: Provided is a pixel circuit comprising two sub-pixel circuits(P1, P2) of the same structure. Each sub-pixel circuit(P1, P2) comprises five switch units(T1, T2, T3, T4, T5), a driving unit(DT), an energy storage unit(C) and an electroluminescent unit(L). The two sub-pixel circuits (P1, P2) are connected to the same operating voltage line(Vdd), the same data voltage line(Vdata), the same first scanning signal line(Scan[1]), and the same third scanning signal line(Scan[3]), and are connected to different second scanning signal lines(Scan[2]), so that in the pixel circuit, the operating current flowing through the electroluminescent unit(L) is not affected by the threshold voltage of the corresponding driving transistor, completely solving the problem of non-uniformity in the display brightness due to drifting of the threshold voltage of the driving transistor. 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. Also provided is a display apparatus using the pixel circuit.

    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.
