Abstract:
A pixel circuit for controlling driving current for a light-emitting element is disclosed. The pixel circuit includes a driving transistor configured to supply driving current to the light-emitting element, a first switching transistor configured to transmit a data signal corresponding to the driving current, a storage capacitor configured to receive the signal from the first switching transistor and store a voltage to be applied to a gate of the driving transistor, a second switching transistor configured to correct the voltage to be stored to the storage capacitor, and a first capacitor including an electrode connected with a drain of the driving transistor and an electrode to be supplied with a predetermined potential.
