Rcently, Capella Microsystems introduced CM36262 Optical-Lid-Sensor Chip for targeting use in tablet computers, notebooks, and smartphones. It contains a patent-pending optical-lid sensor, an ambient-light sensor, and a proximity sensor. Users can easily power down touch screen products via the lid sensor. The screen brightness can be adjusted through the ambient-light sensor, thus to extend battery life. In addition, the proximity sensor turns off dialing when a user holds a smartphone in the listening position next to an ear.

The CM36262 optically senses the presence of a lid or a fabric cover on touchscreen products, replacing the standard method of using magnets or mechanical switches. The optical method is less expensive and more reliable; it enables users to power down a tablet computer using a fabric or a leather cover without aligning an embedded magnet over a pickup sensor. Prices begin at 79 cents (1000) in an optical-land-grid package that measures 2.35×1.8×1 mm.
