Electronic devices having displays with openings
An electronic device may have a display. The display may have an active region in which display pixels are used to display images. The display may have one or more openings and may be mounted in a housing associated with the electronic device. An electronic component may be mounted in alignment with the openings in the display. The electronic component may include a camera, a light sensor, a light-based proximity sensor, status indicator lights, a light-based touch sensor array, a secondary display that has display pixels that may be viewed through the openings, antenna structures, a speaker, a microphone, or other acoustic, electromagnetic, or light-based component. One or more openings in the display may form a window through which a user of the device may view an external object. Display pixels in the window region may be used in forming a heads-up display.
1. An electronic device, comprising:
a housing;
a display mounted in the housing, wherein the display has an active area, an inactive area, an array of pixels in the active area, and a region in the active area; and
a light sensor located behind the display, wherein the light sensor detects light through the region in the active area.
2. The electronic device defined in claim 1 wherein the pixels comprise organic light-emitting diode pixels.
3. The electronic device defined in claim 2 wherein the region is interposed between a pair of the organic light-emitting diode pixels.
4. The electronic device defined in claim 1 wherein the display comprises a polymer substrate on which the array of pixels is located.
5. The electronic device defined in claim 4 wherein the polymer substrate comprises first and second opposing surfaces and wherein the region comprises an opening that passes from the first surface to the second surface.
6. The electronic device defined in claim 5 wherein display comprises a layer of thin-film transistor circuitry, a layer of organic emissive material, and a layer of sealant.
