Abstract

The invention provides a pixel circuit, a driving method and a display device. The pixel circuit comprises a driving circuit, a first initialization circuit and a reset circuit. The first initialization circuit writes a first initial voltage into the first end of the driving circuit under the control of an initialization control signal; the reset circuit controls a reset voltage end to write a reset voltage into the second end of the driving circuit or the first end of the driving circuit under the control of a second scanning signal; the drive circuit is used for controlling the first end of the drive circuit to be communicated with the second end of the drive circuit under the control of the potential of the control end of the drive circuit.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a pixel circuit, a driving method and a display device. Background technique [0002] When the related display panel is in operation, the magnetic hysteresis of the driving transistor in the driving circuit included in the pixel circuit will cause the characteristic response of the driving transistor to be sluggish, thereby affecting the display. Contents of the invention [0003] In one aspect, an embodiment of the present disclosure provides a pixel circuit, including a driving circuit, a first initialization circuit and a reset circuit; [0004] The first initialization circuit is electrically connected to the initialization control line, the first terminal of the driving circuit, and the first initial voltage terminal, and is used to control the initialization control signal provided by the initialization control line. A first initial voltage provided by an i...
