Patent ID: 7427833

Claim:
A display device comprising a plurality of pixels carried on a substrate, each pixel comprising: a current-driven display element coupled between a first conductive layer and a second conductive layer, the second conductive layer being coupled to a current supply via a switchable device having a thin film component on a first area of the substrate and the second conductive layer not extending over the thin film component; a first capacitive device comprising: a first capacitor plate in contact with a second area of the substrate, the first capacitor plate being conductively coupled to the thin film component; a second capacitor plate overlaying the first capacitor plate; and a first insulating layer between the first capacitor plate and the second capacitor plate and disposed in the switchable device for insulating the thin film component; each pixel further comprising: a second capacitive device sharing the second capacitor plate of the first capacitive device, the second capacitive device further comprising a third capacitor plate overlaying the second capacitor plate, the third capacitor plate comprising at least a part of the second conductive layer, and a second insulating layer between the second capacitor plate and the third capacitor plate.
