Abstract: A device includes a display stack and an optical receiver. The display stack includes a set of opaque elements defining a translucent aperture. The translucent aperture extends through the display stack. The optical receiver is spaced apart from and behind a back surface of the display stack. At least one micro-optic element is formed on the back surface of the display stack, between the display stack and the optical receiver. The at least one micro-optic element includes a micro-optic element having a focal point located within the translucent aperture. The optical receiver is configured to receive light through the translucent aperture and the at least one micro-optic element.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. A pixel removal region on the display may at least partially overlap with the sensor. The pixel removal region may include a plurality of non-pixel regions each of which is devoid of thin-film transistors. The plurality of non-pixel regions is configured to increase the transmittance of light through the display to the sensor. In addition to removing thin-film transistors in the pixel removal region, additional layers in the display stack-up may be removed. In particular, a cathode layer, polyimide layer, and/or substrate in the display stack-up may be patterned to have an opening in the pixel removal region. A polarizer may be bleached in the pixel removal region for additional transmittance gains. The cathode layer may be removed using laser ablation with a spot laser or blanket illumination.

Abstract: An electronic device may include an optical image sensor, a pin hole array mask layer above the optical image sensor, and a display layer above the pin hole array mask layer and including spaced apart display pixels. The electronic device may also include a transparent cover layer above the display layer defining a finger placement surface configured to receive a finger adjacent thereto, and an optically transparent light source layer between the transparent cover layer and the display layer. The optically transparent light source layer may include an optically transparent light source.
