Problems solved by technology

[0002] Most of each transistor in the pixel circuit of the traditional technical solution needs to configure at least one wiring as its control signal line and / or input signal line, which requires a large number of signal lines, resulting in an increasing area occupied by each pixel. The bigger it is, it is not conducive to improving the display resolution

Abstract

The invention discloses a pixel circuit and a display panel, the pixel circuit comprises a second wiring, a first light-emitting control unit, a driving unit and a compensation unit, the control end of the first light-emitting control unit and the control end of the compensation unit share the second wiring, the number of the wiring of the pixel circuit can be reduced, and then the display resolution is improved; meanwhile, the control end of the driving unit is only provided with the compensation unit, so that the leakage path of the control end of the driving unit is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel circuit and a display panel. Background technique [0002] Most of each transistor in the pixel circuit of the traditional technical solution needs to configure at least one wiring as its control signal line and / or input signal line, which requires a large number of signal lines, resulting in an increasing area occupied by each pixel. The bigger it is, it is not conducive to improving the display resolution. [0003] It should be noted that the above introduction about the background technology is only for the purpose of clearly and completely understanding the technical solution of the present application. Therefore, it cannot be considered that the technical solutions mentioned above are known to those skilled in the art just because they appear in the background technology of the present application. Contents of the invention [0004] The present applica...
