Abstract
An OLED display with a photosensor includes a substrate; a display area comprising an array of addressable OLEDs formed on the substrate; and an elongated photosensor formed on the substrate and located along an edge of the display area and responsive to ambient illumination to generate a feedback signal in response thereto, the elongated photosensor having a first conductive electrode that extends the length of the photosensor and a second conductive electrode.
