1. A system comprising:
- a dual-mode display operable in an opaque mode when displaying opaque portions of a display image, the dual-mode display operable in a transparent mode when not displaying the display image, the dual-mode display comprising a substantially transparent cathode layer, a plurality of organic light emitting diodes, and a substantially transparent anode layer;
a selectively addressable region associated with the dual-mode display, the selectively addressable region disposed above a camera, the selectively addressable region operable to be transparent when remainder of the dual-mode display is in the opaque mode, and when the selectively addressable region is transparent, the selectively addressable region to allow light to enter the camera, and to allow light to exit the camera;
a first set of electrodes to activate and to deactivate the dual-mode display except the selectively addressable region;
a second set of electrodes to activate and to deactivate the selectively addressable region; and
a display controller to send a first signal and a second signal to the selectively addressable region, the first signal to turn the selectively addressable region transparent, and the second signal to turn the selectively addressable region opaque.

Abstract
The technology disclosed here integrates a light sensor with a dual-mode display, thus increasing the size of the dual-mode display. The light sensor can be a camera, an ambient sensor, a proximity sensor, etc. The light sensor is placed beneath the dual-mode display and can detect incoming light while the dual-mode display is displaying a display image. The dual-mode display and the light sensor can operate at the same time. For example, a camera placed beneath the dual-mode display can record an image of the environment, while at the same time the dual-mode display is showing the display image. Further, multiple light sensors can be placed at various locations beneath the dual-mode display.

17. A method comprising:
-
configuring a dual-mode display to become opaque when displaying opaque portions of a display image, the dual-mode display to become substantially transparent when not displaying the display image; placing a light sensor beneath a selectively addressable region associated with the dual-mode display, the light sensor to activate and deactivate, and when the light sensor activates the light sensor to detect a property of incoming light, said placing comprising establishing a correspondence between the light sensor and the selectively addressable region, said establishing the correspondence comprising; configuring a first set of electrodes to activate and to deactivate the dual-mode display except the selectively addressable region; configuring a second set of electrodes to activate and to deactivate the selectively addressable region; and configuring the selectively addressable region to not to display the display image when the light sensor activates while at least a portion of the dual-mode display is displaying opaque portions of the display image, such that the inactive selectively addressable region tends to be unnoticeable to a user. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
