Laser diode technology is being developed that could someday allow you to project video downloaded to your mobile phone onto a wall or screen.
An essential element of portable video projectors is the laser diode, which projects the video image at sufficient brightness onto a screen or other flat surface. Glass and ceramics specialist Corning is developing a green laser diode that will take up only about one cubic centimetre of space and work in projectors that will put out 10 to 20 lumens of brightness -- equivalent to what an LCD monitor gives off -- to project an image that measures 9 to 12 inches (23cm to 30.5cm) diagonally.
