Abstract
A pixel circuit, a driving method therefor, and a display device. The pixel circuit comprises: a current control circuit (), a duration control circuit (), and a light-emitting element (), wherein the current control circuit () is used for receiving a data signal (DI) and a first scan signal (gataA), and controlling the amplitude of a generated drive current according to the data signal (DI) and the first scan signal (gataA), and the duration control circuit () is used for receiving a mode control signal (DT), a pulse control signal (hf), a light-emitting control signal (em_b), and the drive current of the current control circuit (), and controlling, according to the amplitude of the mode control signal (DT), the length of time for providing the light-emitting element () with the drive current.
