Abstract
Embodiments are directed to electronic devices that include a behind-display imaging device and at least one birefringent layer positioned between the behind-display imaging device and a cover layer of the electronic device. In some instances, the birefringent layer(s) may be configured to obscure the presence of light-transmitting regions of the display in an imaging region of the display. Additionally or alternatively, the birefringent layer(s) may help to reduce image artifacts in images captured by the imaging device.
Claims20
An electronic device comprising:
- a cover layer;
- a display;
- an imaging device positioned to collect light through an imaging region of the display;
- and
- a layer stack positioned between the imaging device and the cover layer, wherein the layer stack comprises:
- a set of birefringent layers;
- a retarder layer;
- and
- a polarizing layer.
An electronic device comprising:
- a cover layer;
- a display;
- and
- a plurality of stacked birefringent layers positioned between the display and the cover layer, wherein:
- the plurality of stacked birefringent layers is configured to split incoming rays of light into ordinary rays and extraordinary rays having an overall angle-dependent ray displacement;
- the plurality of stacked birefringent layer comprises:
- a first birefringent layer having a first optical axis;
- and
- a second birefringent layer having a second optical axis with a different orientation that the first optical axis.
An electronic device comprising:
- a cover layer;
- a display comprising an imaging region and a peripheral region at least partially surrounding the imaging region;
- an imaging device positioned to collect light through an imaging region;
- and
- a set of birefringent layers, wherein:
- the set of birefringent layers is positioned between the display and the cover layer within the imaging region;
- and
- the set of birefringent layers is not positioned between the display and the cover layer within the peripheral region.
