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.
Claims20
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 array of pixels comprises a first array of pixels and a second array of pixels, the first array of pixels and the second array of pixels having different sizes of non-optically-active areas,
- 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 plurality of display pixels, the plurality of display pixels comprising first display pixels and second display pixels,
- wherein each display pixel comprises a non-optically-active area configured to not emit light when the display pixel is operating and includes a material of the first layered structure that is substantially transparent to infrared light having a wavelength between 1100 nm and 1600 nm,
- wherein the first display pixels and second display pixels have different sizes of non-optically-active areas;
- constructing a functional layer of the electronic device by disposing at least one infrared component, the first layered structure located between the at least one infrared component and the transparent protection layer,
- wherein the at least one infrared component comprises a dilute nitride semiconductor material and detects or emits the infrared light through a material of the first layered structure at the non-optically-active areas;
- creating a second layered structure carrying electronic connection circuitry electrically connected to at least one of the first layered structure or the functional layer;
- disposing the first layered structure and the functional layer in and within bounds of a housing shell such that the non-optically-active areas are positioned between the at least one infrared component and the transparent protection layer.
