It solves the size problem through projecting a big enough screen. Pico projector can be carried by businessmen to process prompt presentation or be shared the video or audio with friends by new generations; more further, it can integrate various mobile electronic devices like cell phone, digital camera, NB, i-pod, video, PDA and palm game machine, etc. to achieve the goals of pleasure, sharing and working. Plus the concept of creative multiple screens and combinative projector, we can develop immense practical market and industrial value. Consumer groups include business users who need to present in a small space and young generation who love to share pictures and movies immediately. This thesis has mentioned few issues. First is about how to design a system driver equipment of laser optical engine (using laser diode as a light source and MEMS mirror to scan the light deviation.) Because MEMS mirror dose not scan the light deviation by sequence but by Lissajous, the major consideration is the cooperation of projector point calculation and hardware. Second is driver system design (driver of MEMS mirror and laser diode.) Others are going to reveal more in the thesis.
