This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling lighting of a display based on ambient light conditions. In one aspect, a display device can include a display and an auxiliary light source configured to provide supplemental light to the display. The display device further can include a sensor system configured to measure a diffuse illuminance of ambient light from a wide range of directions and configured to measure a directed illuminance of the ambient light from a relatively narrow range of directions. The display device further can include a controller configured to adjust the auxiliary light source to provide an amount of supplemental light to the display. The amount of supplemental light can be based at least in part on the measured directed illuminance and the measured diffuse illuminance of the ambient light. |
