Abstract: An example operation of this disclosure monitors, measures, and/or determines a decay level of a light-pass region of a display and apply compensation to the light-pass region to compensate for the decay. The light-pass region of a display allows ambient light to be transmitted through the display in one direction while the display emits light in the opposite direction. For example, the light-pass region may have reduced or removed reflective layers that enables more light to pass through, or may have pixels of a different density, shape, or size than the rest of the pixels for enabling light passing through. Such structural differences often cause the light-pass region to deteriorate at a higher rate than normal pixels in the display, and darken the light-pass region over time. To address such problems, the present disclosure provides techniques to accurately brighten or otherwise restore the visual appearances of the darkened pixels.
