Abstract

The invention provides a pixel circuit, a driving method, a display substrate, a manufacturing method and a display device. The pixel circuit comprises a light-emitting element, a driving circuit, a compensation control circuit and a one-way conduction circuit. The first end of the compensation control circuit is electrically connected with the first end of the driving circuit, and the second end of the compensation control circuit is electrically connected with the first end of the one-way conduction circuit; the second end of the one-way conduction circuit is electrically connected with the control end of the driving circuit, and the one-way conduction circuit is used for controlling the second end of the compensation control circuit to be communicated with the control end of the driving circuit when the difference value between the potential of the second end of the compensation control circuit and the potential of the control end of the driving circuit is larger than or equal to the conduction voltage and controlling the second end of the compensation control circuit and the control end of the driving circuit to be disconnected when the difference value between the potential of the second end of the compensation control circuit and the potential of the control end of the driving circuit is smaller than the conduction voltage. The potential of the control end of the driving circuit can be stabilized in the light emitting stage.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a driving method, a display substrate, a manufacturing method and a display device. Background technique [0002] When the existing pixel circuit is in operation, when displaying in low grayscale, since the potential of the control terminal of the driving circuit is higher than that of the first terminal of the driving circuit, the leakage current of the transistor in the compensation control circuit flows from the control terminal of the driving circuit to the driving circuit The first terminal of the drive circuit lowers the potential of the control terminal of the drive circuit; since the potential of the control terminal of the drive circuit controls the drive current generated by the drive circuit, the light emission of the light-emitting element will be unstable, resulting in poor display. Contents of the invention [0003] The main purpose of th...
