Abstract
A pixel circuit, a light-emitting control circuit, a driving method of a pixel circuit, a display panel, and a display device are provided. The pixel circuit includes an enabling module, a light-emitting control module, a first reset module, and a light-emitting element connected in series between a power voltage terminal and a common voltage terminal. The first reset module is electrically connected to a first terminal of the light-emitting element. The enabling module is configured to generate driving current, and the light-emitting control module is configured to transmit the driving current to the light-emitting element. The first reset module is configured to reset the first terminal of the light-emitting element. A control terminal of the light-emitting control module is configured to receive a first light-emitting control signal, and a control terminal of the first reset module is configured to receive a second light-emitting control signal.
