US Patent:

20170255813, Sep 7, 2017
Filed:

Sep 30, 2016
Appl. No.:

15/282434
Inventors:

- Redmond WA, US
Yan Cheng - Bellevue WA, US
International Classification:

G06K 9/00
F21V 8/00
G02B 5/32
G03H 1/02
Abstract:

An electronic device includes an image sensing display. The display includes a cover glass and is configured as a waveguide. A volume holographic grating in the display diffracts incident light from an object positioned outside the display. The diffracted incident light has an angle of incidence relative to the volume holographic grating that satisfies the Bragg condition. The volume holographic grating diffracts the incident light through the waveguide at a predetermined angle and with a predetermined waveguide exit distance to focus at the image sensor. An image sensor is positioned at an output of the waveguide to capture the diffracted incident light propagated through the waveguide. Image processing circuitry is coupled to the image sensor to recognize a fingerprint image captured by the image sensor through the waveguide.
