Abstract:
An actuating mechanism for rotating a micro-mirror, comprising:a substrate formed thereon a first recess region; a shaft secured to said micro-mirror for rotating said micro-mirror therewith in said first recess region; a first actuator mounted on said substrate beside said first recess region for providing a first actuating force; a first linking rod device including a first linking rod and a first fulcrum positioned between a first and a second portions of said first linking rod, said first portion being flexibly connected to said shaft, and said second portion being coupled to said first actuator; a second actuator mounted on said substrate beside said first recess region opposite to said first actuator for providing a second actuating force; and a second linking rod device including a second linking rod and a second fulcrum positioned at one end of said second linking rod, said second linking rod including a third portion flexibly connected to said shaft, and a fourth portion coupled to said second actuator; wherein said second and fourth portions are moved in response to said first and second actuating forces to lever said first and third portions via said first and second fulcrums, respectively, thereby rotating said shaft.
