Abstract:
A pixel circuit includes a light emitting element, a driving switching element, a storage capacitor, a data voltage applying switching element and a first leakage compensation switching element. The driving switching element is configured to apply a driving current to the light emitting element. The storage capacitor is connected to a control electrode of the driving switching element. The data voltage applying switching element is configured to apply a data voltage to the storage capacitor. The first leakage compensation switching element is disposed between the storage capacitor and the data voltage applying switching element.
