Microvision's system uses a set of three lasers—red, green and blue—and a single, millimeter-wide silicon mirror that tilts on two axes. The lasers put out light at different intensities, and the three colors are mixed to produce the final pixel color. As the lasers shine light on the mirror, it rapidly scans horizontally and vertically, painting the image onto the windshield one pixel at a time. This happens so fast that the image looks static. Evans says that the lasers' pure, saturated colors result in more vivid images with a higher contrast ratio, so they are visible in daylight. Illuminating one pixel at a time also saves energy. And the use of a single mirror rather than an array makes the device smaller, simpler, and cheaper.
