Abstract
Official abstract text for this publication.
A pixel circuit has a first capacitor having a first terminal connected with a gate of a 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; a third switch supplying an initialization voltage to a drain of the driving transistor and a fourth switch supplying current to the drain of the transistor for emitting light from the current light emitting device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display apparatus having a plurality of arrayed pixel circuits, each of the pixel circuits comprising: a current light emitting device; a driving transistor supplying current to the current light emitting device; a first capacitor having a first terminal connected to 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…
