Abstract
One example provides a method enacted on a display device comprising an organic light emitting diode (OLED) display panel and a light sensor positioned behind the OLED display panel with respect to a viewing surface of the OLED display panel. The method comprises receiving data samples from the light sensor and determining a temporal location for each of one or more non-emissive states of the OLED display panel. The method further comprises determining an ambient light characteristic using one or more data samples acquired during the one or more non-emissive states of the OLED display panel and adjusting an emission characteristic of the OLED display panel based at least in part on the ambient light characteristic determined.
