Abstract
An electronic device includes a cover glass having a display surface, a pixelated photoemitting element array, and a pixelated photodetecting element array. The pixelated photoemitting element array emits a light signal through the cover glass to the display surface. The pixelated photodetecting element array is positioned relative to the pixelated photoemitting element array and the cover glass to receive a reflected light signal. The reflected light signal includes a portion of the emitted light signal reflected by total internal reflection from a refractive boundary at the display surface. Operation of each pixel is switched between the one or more photodetecting elements and the one or more photoemitting elements by the pixel selector signal component received from the pixel selector signal bus. A sensing trigger is configured to trigger the imaging scan by the pixelated photoemitting element array and the pixelated photodetecting element array, responsive to detection of an initiating action.
