Abstract: A display panel, a driving method, and a display device are disclosed. The display panel includes a plurality of pixel units, a gate driver, a source driver, a plurality of feedback lines, and a control module. The display panel is provided with the plurality of feedback lines electrically connected to the gate driver and the control module, such that the control module can detect turn-on time of the pixel units respectively located in at least two pixel areas through the plurality of feedback lines and adjust time when the source driver outputs data signals according to the turn-on time. This solves an issue of uneven display brightness due to inconsistent pixel charging time in the prior art.

Abstract: The present application discloses a display device and electronic device. The display device is configured by sequentially configuring the corresponding first bias current, second bias current, and third bias in a start period, a sustain period, and an end period. The current value of the first bias current is greater than the current value of the second bias current, and/or the current value of the third bias current is greater than the current value of the second bias current, which improves the display quality and reduces display power consumption.
