  • Electroluminescent composition without initial drop of efficiency
    Publication number: 20070164256
    Abstract: The invention relates to an electroluminescent composition comprising an electroluminescent material containing an aryl vinylene and an additive for suppressing a drop in the initial efficiency of light emission observed when the electroluminescent material is used as such in an electroluminescent device. The invention further relates to an electroluminescent composition comprising an electroluminescent material containing an aryl vinylene and an additive, wherein the additive comprises an oligo ring structure with at least four carbonyl groups and to an electroluminescent device comprising the composition according to the invention.

  • Display device
    Publication number: 20050280766
    Abstract: The invention relates to a display device for displaying an image comprising a plurality of display pixels (2), a controller (3) for generating a driving signal (8) for driving the pixels (2), and sensors (9; 11; 14), wherein the sensors (9; 11; 14) are able to monitor operating conditions of the pixels (2), and the controller (3) is adapted to receive data related to the operating conditions from the sensors (9; 11; 14) to determine a brightness change of the pixels (2) caused by the operating conditions and to generate the driving signal (8) in dependence on the brightness change.

  • Active plate for a display device having a conductive layer with increased conductivity
    Patent number: 6885425
    Abstract: A method of increasing the conductivity of a transparent conductive layer, in which a photoresist layer which patterns the transparent layer is given tapered edges and is partially etched. The partial etching exposing the edge regions of the underlying transparent conductor layer, which are the selectively plated. This method has a single patterning stage of the transparent layer, but uses partial etching of a tapered resist layer in order to expose a small edge region of the transparent layer for coating with a conductive layer (which can be opaque).
