Abstract
An electronic device may include an optical image sensor and a pin hole array mask layer above the optical image sensor. The electronic device may also include a display layer above the pin hole array mask layer that includes spaced apart display pixels, and a transparent cover layer above the display layer defining a finger placement surface capable of receiving a finger adjacent thereto.

An electronic device comprising:
- an optical image sensor;
- a pin hole array mask layer above the optical image sensor;
- a display layer above the pin hole array mask layer comprising a plurality of spaced apart light emitting diodes (LEDs);
- and
- a transparent cover layer above the display layer defining a finger placement surface capable of receiving a finger adjacent thereto;
- the plurality of spaced apart LEDs providing illumination for the optical image sensor, and being aligned with the pin hole array mask layer so that light reflected from the finger adjacent the finger placement surface passes through the pin hole array mask layer and between the plurality of spaced apart LEDs to the optical image sensor.

A method of using an electronic device comprising:
- using a plurality of spaced apart light emitting diodes (LEDs) of a display layer to direct light into a finger when adjacent a transparent cover layer defining finger placement surface capable of receiving the finger adjacent thereto;
- and
- using an optical image sensor to sense reflected light from the finger adjacent the finger placement surface, the reflected light being sensed through a pin hole array mask layer above the optical image sensor, the display layer being above the pin hole array mask layer, the display layer comprising the plurality of spaced apart LEDs, and the transparent cover layer above the display layer;
- the plurality of spaced apart LEDs providing illumination for the optical image sensor, and being aligned with the pin hole array mask layer so that light reflected from the finger adjacent the finger placement surface passes through the pin hole array mask layer and between the plurality of spaced apart LEDs to the optical image sensor.
