## Abstract

Systems and methods for through-display imaging. A display includes an imaging aperture defined through an opaque backing. An optical imaging array is aligned with the aperture. Above the aperture, the display is arranged and/or configured for increased optical transmittance. For example, a region of the display above, or adjacent to, the imaging aperture can be formed with a lower pixel density than other regions of the display, thereby increasing inter-pixel distance (e.g., pitch) and increasing an area through which light can traverse the display to reach the optical imaging array.

## Claims

### Claim 1

A mobile device comprising:
a display having a plurality of light emitting pixels distributed over a display area, the display area having,
a first pixel region having a first pixel density, the first pixel density associated with a first number of the light emitting pixels per unit area; and
a second pixel region that is separate from the first pixel region and has a second pixel density, the second pixel density associated with a second number of the light emitting pixels per the unit area; wherein,
the first number of light emitting pixels is different than the second number of light emitting pixels.
