Abstract

The invention provides a pixel circuit, a driving method and a display panel. The pixel circuit comprises a sharing unit and N control light-emitting units, wherein an input end of each control light-emitting unit is electrically connected with an output end of the sharing unit; an output end of each control light-emitting unit is electrically connected with a corresponding light-emitting element, and a control end of each control light-emitting unit is electrically connected with a corresponding control signal line; the sharing unit is used for driving each light-emitting element, which is correspondingly and electrically connected with the output end of the corresponding control light-emitting unit, to emit light through the corresponding control light-emitting unit; and N is a positive integer greater than or equal to 2. The pixel circuit, the driving method and the display panel can achieve the effects of solving the uneven display problem caused by transistor threshold value drift, being compatible with process capability, and increasing a resolution ratio of the organic light emitting display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of organic light emitting display technologies, and in particular, to a pixel circuit, a driving method, and a display panel. Background technique [0002] Compared with traditional liquid crystal display panels, organic light-emitting display panels have the characteristics of fast response, high contrast, and wide viewing angles. The organic light-emitting display panel can emit light because the driving transistor generates a driving current in a saturated state. However, due to the aging of the device and other reasons, the threshold voltage of the driving transistor will drift, causing the driving current to change, thereby causing the luminance of the organic light-emitting display panel to change and affecting the display uniformity. [0003] In order to solve the problem that the threshold voltage drift of the driving transistor leads to the uneven display of the machine light-emitting d...
