Abstract: An electroluminescent device in accordance with the present invention includes a plurality of pixel electrodes disposed on a dielectric layer and coupled to control circuitry. An electroluminescent stack and a transparent electrode are included wherein the electroluminescent stack is disposed between the transparent electrode and the plurality of pixel electrodes. A plurality of guides are disposed between each of the pixel electrodes for guiding light from the electroluminescent stack when the pixel electrodes are activated by the control circuitry and reducing internal reflections of light within the electroluminescent stack. Another device and method include a dielectric layer disposed between the pixel electrodes for absorbing light and reducing a threshold voltage of the stack.

Abstract: An electroluminescent device in accordance with the present invention includes a first conductive layer having a portion thereof for connecting to a gate of a blocking transistor formed on a substrate. A dielectric layer is formed on the first conductive layer, the dielectric layer having a dielectric constant of at least six. A second conductive layer is formed on the dielectric layer such that the first and second conductive layers have portions which form electrodes of a hold capacitor and the dielectric layer provides a capacitor dielectric between the electrodes such that the dielectric layer continuously covers the device. A pixel electrode is associated with and coupled to the blocking transistor.
