Abstract
Various embodiments concern sensors and other components that can be disposed beneath a variable transparency layer of a mobile device. By modifying how much voltage is applied to the variable transparency layer, a component, such as a camera, can be readily hidden when not in use. More specifically, the variable transparency layer may be substantially opaque when the camera is not in use and at least partially transparent when the camera is in use and ready to capture an image. The opacity level of the variable transparency layer can be modified by a voltage source that is electrically coupled to the variable transparency layer. The various levels of opacity could also enable the variable transparency layer to act as an electronic aperture for the camera.

21. An electronic device comprising:
-
a display, a portion of said display comprising a first variable transparency region defining a variably light transmissive aperture through said display, wherein the first variable transparency region is operable from transparent to opaque in response to a signal applied thereto; and a sensor disposed directly beneath the first variable transparency region; wherein light is received by the sensor through said display said when said first variable transparency region is operated to be transparent; and wherein said first variable transparency region is opaque when said first variable transparency segment is operated to be opaque. - View Dependent Claims (22, 23, 24, 25, 27)
