Abstract
Disclosed are circuits and user interfaces of a mobile communication device that include a light source and a shutter that are driven by at least one common voltage line. Also disclosed are circuits and user interfaces of a mobile communication device that include a sensor and a shutter that are driven by at least one common voltage line. Further disclosed are circuits and user interfaces that include a light source, a sensor and a shutter that are driven by at least one common voltage line. The shutter may be divided into a plurality of segments so that one segment may be in optical alignment with a light source and another segment may be in optical alignment with a sensor. A shutter may be part of the same circuit as a light source and/or a sensor without needing its own circuit and driver.
