Abstract
A small device for projecting images from a video generating device such as a computer, television receiver, or similar device onto a screen or other surface is described in this invention. The device is the size of the pen, and converts video instructions using a processing unit and memory into light signals that are projected. In the one embodiment, the device uses pulsed laser light from red, green, and blue lasers that are combined into a single light pulse that is transmitted through a rotating disk containing numerous lenses that transmit each light pulse to a specific location on the screen.
