Abstract: The present disclosure discloses a circuit and method for generating a light emission control signal for an AMOLED pixel circuit having in-cell touch sensors, as well as a pixel circuit driving method. The circuit comprises a first transistor, a second transistor, a third transistor, a fourth transistor and a first capacitor. Under control of a control signal transferred by a first control line, a first clock signal, a second clock signal, a voltage of a first level, a voltage of a second level and a control signal transferred by a second control line, the circuit outputs the desired light emission control signal via a light emission control line. The light emission control signal may turn off the OLED in the pixel circuit during a touch sense phase such that an influence of the capacitance between the anode and cathode of the OLED on the touch sensor-to-ground capacitance is reduced.
