PICO PROJECTOR UNIT

摘要

PURPOSE: A pico projector unit is provided to improve the efficiency of lights by providing position coordination between an area being projected by a fold mirror and a DMD panel. CONSTITUTION: A pico projector unit comprises a light equalizing unit. The light equalizing unit is formed in between a light source and a fold mirror(151). The light equalizing unit uniformly transmits lights transmitted from the light source to a rear part and forms lights having a square shaped optical profile. The light equalizing unit forms a plurality of square shaped micro lens cell arrays in order to transmit the lights to the fold mirror. The light equalizing unit corrects the gradient of the lights having the square shaped optical profile being transmitted to a DMD panel(171) by the fold mirror.
