Method and device for reading display pixel emission and ambient luminance levels
First Claim
1. A method for detecting an input to a display device having a first plurality of separately addressable picture element (pixel) locations arranged as a two-dimensional array, the method comprising:
- providing a photon sensing element proximate at least some of the first plurality of separately addressable pixel locations in the two-dimensions of the array;
detecting photons impinging on each of the sensing elements during predetermined detection time periods;
generating a sensed signal for each of the photon sensing elements corresponding to the number or energy of the detected photons; and
analyzing the sensed signals to identify at least one pixel location that has received an input.

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.
