Abstract
Disclosed is a pixel circuit. A pulse width signal generator provides a pulse width signal to a control terminal of a light-emitting control switch on a drive current path of a drive current generator. A multiple lighting controller adjusts the pulse width signal provided by the pulse width signal generator according to a multiple emission control signal to allow a light-emitting element to perform multi-emission.
Claims15
A pixel circuit, comprising:
- a light-emitting element, coupled to a power supply voltage;
- a drive current generator, coupled to the light-emitting element and providing a drive current through a drive current path to drive the light-emitting element;
- a pulse width signal generator, providing a pulse width signal to a control terminal of a light-emitting control switch on the drive current path;
- and
- a multiple lighting controller, coupled between the control terminal of the light-emitting control switch and the drive current generator, and adjusting the pulse width signal according to a multiple emission control signal to allow the light-emitting element to perform multi-emission.
