Entering your destination while driving can be rather dangerous. Some navigation systems can, therefore, only be operated when the vehicle is standing still. One method for drivers to receive additional information without taking their eyes off the road is to reflect additional display elements onto the windshield.

Blaupunkt ( is offering such a “heads-up display” in which three multicolored bundles of laser light (red, green and blue) can be written line by line from top to bottom on a projection surface by means of a deflection unit similar to the system in an electron beam picture tube. The horizontal and vertical deflection is carried out by a two-axle scanner mirror which is produced micro-mechanically on a silicon chip, and whose surface is smaller than 0.5 square centimeters.
