We have built a mini‐projector with LED light sources that is sufficiently small for portable applications. The projector has a three panel architecture with transmissive LCD micro‐displays in order to combine a high lumen output with a low cost price. The volume of the light engine is 110 cc. The projector can deliver up to 15 lumen to the screen at a LED power of 9 W. In the high efficiency mode the output is 8.5 lumen at 3.8 W.
