Abstract:
1. An OLED display and touch screen system, comprising: a) a substrate; b) an OLED display including an array of individually addressable OLEDs formed on the substrate; and c) a touch screen including an OLED light emitter formed on the substrate the OLED light emitter defining an optical cavity for reducing the angle of emission of light from the OLED light emitter and a light sensor formed on the substrate across the display from the OLED light emitter, and optics located around the display above the OLED light emitter and the light sensor for directing light emitted from the OLED light emitter across the display to the light sensor, wherein the OLED light emitter and the light sensor of the touch screen are integrated on the substrate with the individually addressable OLEDs of the OLED display.
