ABSTRACT:
An apparatus includes a display panel capable of displaying content. The apparatus also includes a light sensor having an integrated circuit and a photo-sensitive device. The photo-sensitive device is capable of measuring an amount of ambient light. The integrated circuit is capable of performing one or more functions associated with the display of the content on the display panel. The apparatus further includes a controller capable of adjusting one or more characteristics of the display panel based on the amount of ambient light measured by the light sensor. The integrated circuit and the photo-sensitive device may be formed on one side of a semiconductor wafer, and the photo-sensitive device may be exposed to the ambient light through an opening in an opposing side of the semiconductor wafer.
