Abstract

The invention provides a pixel circuit, a pixel driving method and a display device. The pixel circuit includes a light-emitting element, a driving circuit, a compensation control circuit, a data writing control circuit, and a lighting control circuit, wherein the data writing control circuit is configured to control writing of data voltages into the compensation during the data writing phase. a control circuit; the compensation control circuit is configured to control and compensate the potential of the control terminal of the driving circuit in the compensation phase, and control and adjust the potential of the control terminal of the driving circuit according to the data voltage control in the data writing phase; the The light emission control circuit is configured to control the connection state between the driving circuit and the light emitting element during the light emission phase. The present invention improves display unevenness.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a pixel driving method and a display device. Background technique [0002] In the existing pixel circuit, under the control of the light emission control signal, the power supply voltage ELVDD is input. Since the power supply voltage lines of the input power supply voltage ELVDD are arranged in a row, as the transmission between the pixel circuit and the power supply voltage lines As the distance becomes larger, the voltage value of the power supply voltage input to the far-end pixel circuit is smaller than the voltage value of the power supply voltage input to the near-end, while the luminous brightness of the light-emitting element in the existing pixel circuit is related to ELVDD, thus displaying in the light-emitting stage There will be uneven display at the near and far ends of the screen. Contents of the invention [0003] The main purpose of th...
