Abstract:
The present disclosure provides a pixel circuit, a pixel driving method and a display device. The pixel circuit includes a first initialization circuit and a compensation circuit; the first initialization circuit controls to provide a first initial voltage to the driving control node under the control of the first initial control signal; the compensation circuit controls the compensation node to be connected to the first node under the control of the compensation control signal; at least one of the first initialization circuit and the compensation circuit includes an oxide thin film transistor and a low temperature polysilicon thin film transistor connected in series.
