3M today based its CES unveilings around an update to its MPro pocket projector hardware. The MM200 is a new variant built to be integrated into other devices rather than operating separately. While it can be used in a dedicated projector, the new liquid crystal on silicon (LCoS) unit can be built into a cellphone, camera or other handheld and generates a 640x480 image at up to 50 feet away. Using LEDs helps keep power consumption down to one watt.

The technology firm is eager to stress that the display techniques of MM200 should translate to shipping products sometime in 2009, though outside firms using the projector haven't been named; at present, the power use is significantly more than for typical cellphones.
