Abstract
A micromirror based virtual image head-up Display (HUD) system for automobile is presented. This auto-HUD includes a micromirror laser vector scanning display module, a projection screen, a reflective mirror and a transparent reflector for generating the virtual image. The display module integrates a micromirror driven by four repulsive-force actuators, a laser, the driving and control circuits and a double concave lens. The prototype of the micromirror HUD is fabricated and installed in a car model. Its performance is tested. The micromirror HUD is superior over the conventional HUD in terms of viewing angle, cost and size.
