Projector for portable electronic apparatus
First Claim
1. A projector for projecting an image to a projection plate, comprising:
- a first digital micro-mirror device, with a first micro-mirror disposed thereon;
a second digital micro-mirror device, comprising a plurality of second micro-mirrors disposed thereon; and
a projection light source, emitting a projection beam toward the first digital micro-mirror device;
wherein the first digital micro-mirror device reflects the projection beam from the projection light source to the second digital micro-mirror device, the first micro-mirror is rotated with respect to a vertical axis to adjust a horizontal position where the projection beam is projected on the second digital micro-mirror device, the second digital micro-mirror device reflects the projection beam from the first digital micro-mirror device to the projection plate, and the second micro-mirrors are rotated with respect to an horizontal axis to adjust a vertical position where the projection beam is projected on the projection plate.

Abstract
A projector. The projector comprises a projection light source, a first digital micro-mirror device, and a second digital micro-mirror device. The projection light source emits a projection beam toward the first digital micro-mirror device. The first digital micro-mirror device reflects the projection beam to the second digital micro-mirror device. A first micro-mirror on the first digital micro-mirror device is rotated in a horizontal direction to adjust the horizontal position of the projection beam. The second digital micro-mirror device reflects the projection beam from the first digital micro-mirror device to a projection plate. Second micro-mirrors on the second digital micro-mirror device are rotated in a vertical direction to adjust the vertical position of the projection beam.
