Abstract
An electronic device having a display with an infrared component (such as a camera, a light source) behind the display. The layer of the display is transparent to infrared light at which the infrared component operates. Infrared sensing functions, when implemented by the component, may be accomplished by transmission of infrared light through the layer of the display, thereby removing the conventional need for cut-outs or holes in the display plane and maximizing the display area.
Claims19
An electronic device-comprising:
- a housing;
- at least one infrared component in the housing, wherein the at least one infrared component comprises a dilute nitride semiconductor material;
- and
- a pixelated display layer in optical communication with the at least one infrared component, the pixelated display layer comprising an array of pixels and having at least one transmissive region, the at least one transmissive region including a material of the pixelated display layer that is substantially transparent to infrared light,
- wherein the at least one transmissive region is spatially coordinated with the at least one infrared component such that the at least one infrared component detects or emits the infrared light through the material of the pixelated display layer at the at least one transmissive region, the infrared light having a wavelength between 1100 nm and 1600 nm.

A method for fabricating an electronic device, the method comprising:
- providing a transparent protection layer of the electronic device;
- forming a first layered structure of the electronic device, the first layered structure defining a display pixel and including:
- an optically-active portion of the display pixel;
- and
- a non-optically-active portion of the display pixel, wherein the non-optically-active portion is configured to not emit light when the display pixel is operating,
- wherein the non-optically-active portion includes a material of the first layered structure that is substantially transparent to infrared light;
- constructing a functional layer of the electronic device by disposing an array of infrared components, the first layered structure located between the array of infrared components and the transparent protection layer, wherein the array of infrared components comprises a dilute nitride semiconductor material and detects or emits infrared light having a wavelength between 1100 nm and 1600 nm through the material of the pixelated display layer at the non-optically-active portion;
- creating a second layered structure carrying electronic connection circuitry electrically connected to at least one of the first layered structure and the functional layer;
- disposing the functional layer and the first layered structure in and within bounds of a housing shell such that the non-optically-active portion is positioned between at least one of the array of infrared components and the transparent protection layer.
