Abstract
An optical isolation system is disclosed for use in a display to reduce light that is transmitted from one or more light sources to a camera. The system can include a gasket arranged next to the camera, where the gasket includes an aperture that substantially surrounds a region that is adjacent to a lens of the camera. In some cases, the gasket can reduce optical crosstalk associated with visible light as well as infrared light. The gasket can include a material that is optical opaque to the wavelengths of the light being transmitted. In addition, some layers of the display can include optical disrupting regions formed in a thickness of the layer.

An optical isolation system for reducing an amount of light transmitted from a light source in a display to a light receiving portion of a light sensor positioned behind the display, the optical isolation system comprising:
- a gasket, the gasket defining an aperture, wherein:
- the gasket is disposed between the light source and the light receiving portion of the light sensor,
- the aperture defined by the gasket has a first area along a horizontal plane, the light receiving portion receives light through a lens opening that has a second area along the horizontal plane, and the first area is equal to or greater than second area,
- the lens opening of the light receiving portion is substantially aligned with the aperture,
- the gasket includes a material that is opaque to wavelengths emitted by the light source, and
- the material of the gasket resides outside of the lens opening of the light sensor.
An optical isolation system for reducing an amount of light transmitted from a first light source in a display to two cameras positioned behind the display, including a first camera and a second camera, the optical isolation system comprising:
- a gasket, the gasket defining an aperture, wherein:
- the gasket is disposed between the light source and the two light sensors,
- the aperture has a first zone with an area that is equal to or greater than an area of a second zone of the display that encompasses both a first field of view of the first camera and a second field of view of the second camera,
- the gasket includes a material that is opaque to wavelengths emitted by the first light source, and
- the first zone of the aperture defined by the gasket is substantially aligned with the second zone corresponding to the first field of view and the second field of view, such that the opaque material resides outside of the second zone.
An optical isolation system comprising:
- a light sensor;
- and
- a display including a light source and at least a first layer, wherein:
- the first layer includes a lower surface providing a rear surface of the display,
- the light sensor is positioned behind the rear surface of the display,
- the lower surface includes a first zone that is adjacent to a light receiving portion of the light sensor,
- the lower surface includes an optical disrupting region that extends around and is arranged outside of the first zone, such that the optical disrupting region resides outside the light receiving portion of the light sensor, and
- the optical disrupting region being coated with a material that is opaque to wavelengths emitted by the light source.
