Optical engine and image projecting apparatus having the same
First Claim
1. An optical engine, comprising:
- a base frame;
a video device assembly to generate a video signal;
a driving substrate detachably coupled to the video device assembly to drive the video device assembly, and adapted to be coupled to the base frame such that the video device assembly is disposed therebetween;
a first coupling unit adapted to couple the driving substrate and the video device assembly to the base frame such that a position of the video device assembly with respect to the base frame is adjustable; and
a second coupling unit adapted to couple the video device assembly to the base frame when the position of the video device assembly has been adjusted.

Abstract
An optical engine is provided that includes a base frame, a video device assembly for generating a video signal, and a driving substrate detachably coupled to the video device assembly for driving the video device assembly. The driving substrate is coupled to the base frame such that the video device assembly is disposed therebetween. A first coupling unit couples the driving substrate and the video device assembly to the base frame such that a position of the video device assembly with respect to the base frame is adjustable. A second coupling unit couples the video device assembly to the base frame to secure the adjusted position of the video device assembly to the base frame. The optical engine, and an image projecting apparatus having the same, allow the driving substrate to be replaced without adjusting a position of the video device assembly.
