Abstract
An organic electroluminescent display with integrated touch screen, includes: a transparent substrate having two faces; a transistor switching matrix and a light emitting layer forming an active matrix electroluminescent display located on one face of the substrate for emitting light through the substrate; touch sensitive elements of a touch screen located on the other face of the substrate; components of a touch screen controller located on the one face of the substrate; and an electrical connector for connecting the components of the touch screen controller on the one face of the substrate to the touch screen elements on the other face of the substrate.
