Abstract
In some examples, a display includes a plurality of pixels and a plurality of light sensors. As one example, a respective light sensor may be associated with each pixel. The light sensor output can provide an accurate indication of a current optical state of each of the plurality of pixels. For instance, output from a light sensor proximate to a particular pixel may be used when determining a pixel control signal to be applied for updating the particular pixel to a next optical state. The light sensors may be located below, above, laterally adjacent to, or within one or more pixel elements of each pixel. Additionally, in some examples, one or more light sources may be provided to normalize the output from the light sensors to compensate for variations in ambient lighting and the like.
