|Title:||CIRCUIT AND METHOD FOR GENERATING LIGHT-EMITTING CONTROL SIGNAL, AND PIXEL CIRCUIT DRIVING METHOD|
A circuit and a method for generating a light-emitting control signal of an AMOLED pixel circuit provided with an in-cell type touch sensor, and a pixel circuit driving method. The circuit comprises a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, and a first capacitor Cg. Controlled by a control signal transmitted by a first control line GO, a first clock signal CK, a second clock signal CB, a first level voltage VGH, a second level voltage VGL and a control signal transmitted by a second control line VGL_1, the circuit outputs an expected light-emitting control signal through a light-emitting control line EM. The light-emitting control signal can shut down the OLED in a pixel circuit during the touch sensing period, thereby reducing the influence of the capacitance between the anode and the cathode of the OLED on the capacitance of ground.
