Display apparatus
Abstract:
The display apparatus has a plurality of arrayed pixel circuits. Each of the pixel circuits has a current light emitting device; a driving transistor supplying current to the current light emitting device; a first capacitor having a first terminal connected with a gate of the driving transistor; a second capacitor connected between a second terminal of the first capacitor and a source of the driving transistor; a first switch applying a reference voltage to a node at which the first capacitor and the second capacitor are connected; a second switch supplying an image signal voltage to the gate of the driving transistor, and a third switch supplying an initialization voltage to the source of the driving transistor.
