ABSTRACT:
A display device has a plurality of pixels, each having 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 a substrate. Each pixel has a first capacitive device having a first capacitor plate on a second area of the substrate, the first capacitor plate conductively coupled to the thin film component, a second capacitor plate and a first insulating layer between the first capacitor plate and the second capacitor plate. On top of the first capacitive device is a second capacitive device sharing the second capacitor plate, the second capacitive device including a third capacitor plate sharing the second conductive layer, and a second insulating layer between the second capacitor plate and the third capacitor plate.
