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 having a front and comprising:
- a housing;
- at least one infrared component in the housing;
- and
- a pixelated display layer in optical communication with the at least one infrared component, the display layer comprising an array of pixels and having at least one transmissive region that is substantially transparent to infrared light at a wavelength of interest and that is spatially coordinated with the at least one infrared component to transmit said infrared light between a medium at the front and the at least one infrared component through the at least one transmissive region.

A method for fabricating an electronic device having a front, the method comprising:
- forming a first layered structure of the device, the first layered structure defining a display pixel and including:
- a first layer dimensioned to define an optically-active portion of the display pixel;
- and
- a second layer dimensioned to define a non-optically-active portion of the display pixel, wherein said non-optically-active portion is configured to not emit light in operation of the display;
- constructing a functional layer of the device by disposing an array of infrared components behind the first layered structure, as seen from the front,
- creating a second layered structure carrying electronic connection circuitry electrically connected to at least one of the first layered structure and said functional layer;
- disposing said functional layer and said first layered structure in and within the bounds of a housing shell such that a chosen infrared component of said array of infrared components is positioned behind the non-optically-active portion, as seen from the front.
