Abstract
An OLED display and touch screen system includes a substrate; an OLED display including an array of individually addressable OLEDs formed on the substrate; and a touch screen including an OLED laser light emitter formed on the substrate, a light sensor formed on the substrate across the display from the light emitter, and optics located around the display above the light emitter and the light sensor for directing light emitted from the OLED laser light emitter across the display to the light sensor.
Claims21
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 laser light emitter formed on the substrate, a light sensor formed on the substrate across the display from the light emitter, and optics located around the display above the light emitter and the light sensor for directing light emitted from the OLED laser light emitter across the display to the light sensor, wherein the OLED laser light emitter includes an OLED that emits incoherent light and an organic laser positioned to be optically pumped by the OLED that emits incoherent light.
