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 at least one light source laterally adjacent the optical image sensor and capable of directing light into a user's finger when adjacent the optical image sensor.
Claims18
An electronic device comprising:
- an optical image sensor;
- a mask layer having an array of pin holes and at least one light opening therein;
- a display layer comprising a plurality of spaced apart light emitting diodes (LEDs) configured to provide illumination to the optical image sensor for sensing an object when adjacent the optical image sensor, the mask layer being disposed between the optical image sensor and the display layer;
- and
- at least one light source adjacent the optical image sensor and below the mask layer aligned with the at least one light opening, and configured to direct light into the object when adjacent the optical image sensor and also provide illumination to the optical image sensor for sensing the object when adjacent the optical image sensor.
