Originally they had quite low resolution, but that has increased over time. All of the really small units use an LED light source with two common types. The white LED and LCD panel type, and the RGB source and DLP module. The DLP module (Digital Light Processor) is an array of tiny etched mirrors on a chip that can be deflected by a charge underneath so that they either reflect light through or away from the output lens. They create the RGB image by alternately illuminating a red, green and blue LED while displaying the appropriate image.<br>
