Abstract
A display panel and a display device are provided. One pixel circuit of the display panel includes a driving transistor, a second transistor, a third transistor, a reset module, and a first light-emission controlling module. The second transistor is connected between a data line and a source of the driving transistor, the third transistor is connected between a voltage adjusting signal line and the source of the driving transistor, the reset module is connected between a reset voltage input terminal and a gate of the driving transistor, and the first light-emission controlling module is connected between a first power supply terminal and the source of the driving transistor. An operation process of the display panel includes a light emitting phase, a data writing phase, a reset and adjustment phase, and a reset phase.
