Abstract

Certain aspects of the technology disclosed herein integrate a camera with an electronic display. An electronic display includes several layers, such as a cover layer, a color filter layer, a display layer including light emitting diodes or organic light emitting diodes, a thin film transistor layer, etc. In one embodiment, the layers include a substantially transparent region disposed above the camera. The substantially transparent region allows light from outside to reach the camera, enabling the camera to record an image. In another embodiment, the color filter layer does not include a substantially transparent region, and the camera records the light from the outside colored by the color filter layer. According to another embodiment, while none of the layers include a substantially transparent region, the layers are all substantially transparent, and the camera disposed beneath the layers records light reaching the camera from outside.
