<p>This disclosure provides systems, methods and apparatus for adjusting an output color gamut of a display. The display includes a processor, a planar light guide, and light sensors disposed outside a periphery of the planar light guide. The planar light guide includes a first light-turning arrangement that redirects a portion of light received from the display toward one or more of the light sensors. Each light sensor is configured to output, to the processor, a signal representative of a characteristic of the redirected light. The first light-turning arrangement includes a first light turning element that turns ambient light toward a first light sensor, and a second light turning element that turns light received from the display toward a second, different, light sensor. The processor is configured to adjust an output color gamut of the display, responsive to respective outputs from the first light sensor and the second light sensor.</p> |
