1. A system comprising:
a display panel comprising an adjustable light source;
a light sensor disposed within a sensing distance of the display panel on an opposite surface from the adjustable light source and facing inward toward the adjustable light source, the sensing distance being a distance suitable for the light sensor to sense light of the display panel,
wherein the display panel includes a first side and a second side opposite to the first side, wherein the adjustable light source is disposed on the first side of the display panel and the light sensor is disposed on the second side of the display panel such that the display panel separates the adjustable light source from the light sensor; and
a controller to measure an intensity of light from the light sensor and to control an intensity of the adjustable light source, based, at least in part, on the intensity of the light.
