This paper describes a compact and power-efficient video projector that can be readily integrated into mobile devices such as cell phones. Using state-of-the-art RGB lasers, micro-display panels, and advanced imaging techniques, this 6 cubic centimeter microprojector module can project video graphics array (VGA) resolution color video images that are similar in size and brightness to a notebook computer screen, while consuming only 1.5 watts of electrical power. The microprojector could be ubiquitously deployed as a preferred display device to connect, inform, and entertain the over 3.3 billion cell phone users worldwide.
