Abstract

An OLED display and touch screen system, including: a) a substrate; b) an OLED display area including an array of individually addressable OLEDs formed on the substrate; and c) a touch screen including at least one OLED light emitter formed on the substrate and a plurality of light sensors formed on the substrate across the display area from the light emitter, each of the light sensors having an elongated surface area with a first relatively short dimension and a second relatively long dimension and being positioned adjacent to an edge of the display area, with the relatively long dimension positioned substantially perpendicular to the adjacent edge of the display area, and optics located around the display area above the light emitter and the light sensors for directing light emitted from the light emitter across the display area to the surface area of the light sensors. The system is advantageous in that it enables a thin, light, easily manufacturable display having an integrated optical touch screen having reduced weight, size, and cost, a greater reliability and improved sensitivity and resolution.
