A pixel circuit and a display panel are provided. The pixel circuit includes a driving transistor, a light-emitting circuit, and a controlling circuit. The light-emitting circuit is coupled between the driving transistor and a light-emitting element. The controlling circuit is coupled to the light-emitting circuit and is coupled to the driving transistor at a first node. The controlling circuit sets a first voltage at the first node based on reference voltages according to controlling signals. During a light-emitting period, the light-emitting circuit generates an offset voltage on a first terminal of the light-emitting element according to a light-emitting signal, such that the controlling circuit sets the first voltage based on the offset voltage according to the controlling signals. Further, the driving transistor generates a driving current to the light-emitting element according to the first voltage, so that brightness of the light-emitting element at a high temperature is compensated.
