Compact front-projection devices, which can take images from a phone handset, gaming console or digital camera and project them onto a wall, screen or even a ceiling, now constitute a small but exciting market for LED light sources.

The devices, commonly known as "pocket" projectors, typically weigh less than 1 pound and can be operated from a DC battery supply. However, the size and weight of the battery are such that consumers will need fairly large pockets to carry the whole system, and fairly deep pockets to afford price tags in the EUR 700-1000 bracket.

All pocket projectors currently on the market use LED light sources, and are based on digital light processing (DLP) technology developed by Texas Instruments. Consumer electronics giants such as Samsung, Mitsubishi and Toshiba, along with several other suppliers, already offer pocket projection systems.
