Abstract

Presented here is a system to record high-resolution infrared images without the need to include additional stand-alone sensors into the mobile device. According to one embodiment, an organic light emitting diode (OLED) display is modified to emit IR and near-IR light in a large field. The modified display allows for depth sensing and infrared imaging without a stand-alone emitter. Additionally, an IR shutter filter can be applied to the existing front facing red, green, blue (RGB) camera that would only be in place when the display is in IR emission mode. The combination of these two technologies allows a facial recognition system using existing hardware, and not require additional sensors or emitters to achieve face recognition.
