## Abstract

An integrated display and input device includes a first pixel array operative to provide a visually sensible output, a second pixel array operative to sense at least a position of an object with respect to the first pixel array, and circuitry receiving an output from the second pixel array and providing a non-imagewise input to utilization circuitry.

## Claims

### Claim 1

A device comprising:
a display panel having a pixel array that configured to display digital content and emit light toward an object in proximity to the device;
a cover layer positioned proximate to the display panel, the cover layer including a mask having one or more apertures;
a position sensing array positioned proximate to the cover layer and having a plurality of photodiode detector elements, the position sensing array is configured to receive light that propagates through the one or more apertures of the mask and generates an output signal based on at least a portion of light reflected by the object; and
processing circuitry configured to:
receive the output signal from the position sensing array;
calculate a position and an angular orientation of the object relative to the device based on the output signal from the position sensing array;
determine at least one of the position or the angular orientation of the object corresponds to a portion of the digital content;
execute an input function corresponding to the portion of the digital content.

### Claim 2 (depends on 1)

The device of claim 1, wherein the cover layer includes one or more light diffusing layers.

### Claim 3 (depends on 2)
