Abstract
Light sensing devices are described that have a lens to focus light. In one or more implementations, the light sensing devices include a substrate having a photodetector formed thereon. The photodetector is capable of detecting light and providing a signal in response thereto. The devices also include a display screen that allows light to at least substantially pass through the display screen. An optical baffle extends above a surface of the substrate to display screen and is configured to at least substantially prevent transmission of optical crosstalk to the photodetector. The devices also include a lens disposed proximate to the display screen. The lens is configured to focus light incident upon the lens and to pass the focused light to the photodetector.
