Problems solved by technology

All these additional components add to the cost of the unit, and in a situation where competition is high and profit margins are low, these additional costs are undesirable
In some installations, the cost of adding a touchscreen to the display board can double the cost of the display board alone if it is added after original manufacture

Abstract

System, device, and method for receiving or sensing touch or light input to an emissive display such as to a OLED display using the same or different sensors as are used to sense and maintain a pixel luminance. Penlight and touch screen data input system and method for display. A sidelight illuminated display and touch panel input device. Method and device for reading display pixel emission and ambient luminance levels. Emissive display having sensing for luminance stabilization and user light or touch screen input. Method and device for emissive display using shielded or partially shielded sensors. Emissive pixel display device characterized in that photon sensors are disposed within pixels and operated to sense photons emitted by emitter within pixel and ambient photons emitted by sources outside pixel, sensed internally emitted photons being for luminance feedback control and sensed ambient photons being used to detect external light source or sources.

Description

technical field [0001] The present invention relates generally to systems, apparatus and methods for receiving or detecting contact and non-contact input to the surface of an emissive display device, and more particularly to systems, apparatus and methods for receiving or detecting touch input or light input to a flat-panel organic light emitting diode (OLED) display panel Systems, apparatus and methods wherein the same or a different sensor is used to detect and maintain pixel brightness. Background technique [0002] Many display applications, such as Personal Data Assistants (PDAs), Global Positioning Systems (GPS), and navigation systems incorporating GPS, airport entry check terminals, public computer kiosks, and various other systems and devices contain information added to A touch screen on the display panel, so the user can effectively see an icon or graphic of a data item or action and select a data item or action by pressing a finger or stylus onto that icon.
