Display panel and display device

A display device, comprising a display panel, wherein the display panel comprises:

• at least one light-emitting element;
• at least one pixel circuit coupled to the at least one light-emitting element, wherein one pixel circuit of the at least one pixel circuit comprises a driving transistor and a first transistor that are connected to each other in series;
• and
• at least one comparison module, wherein one of the at least one comparison module is coupled to a gate of the first transistor and is configured to compare a voltage value of a comparison signal and a voltage value of a reference signal to generate a control signal, and to provide the control signal to the gate of the first transistor,
• wherein an operating phase of one pixel circuit of the at least one pixel circuit comprises a light-emitting phase, wherein, during the light-emitting phase, the comparison signal is a constant voltage signal during the light-emitting phase, and a voltage of the reference signal changes over time during at least one period of the light-emitting phase.
