Paper Abstract
A high brightness Head-Up Display (HUD) module was demonstrated with a fast, dual-axis MEMS mirror that displays
vector images and text, utilizing its ~8kHz bandwidth on both axes. Two methodologies were evaluated: in one, the
mirror steers a laser at wide angles of <48° on transparent multi-color fluorescent emissive film and displays content
directly on the windshield, and in the other the mirror displays content on reflective multi-color emissive phosphor plates
reflected off the windshield to create a virtual image for the driver. The display module is compact, consisting of a
single laser diode, off-the-shelf lenses and a MEMS mirror in combination with a MEMS controller to enable precise
movement of the mirror’s X- and Y-axis. The MEMS controller offers both USB and wireless streaming capability and
we utilize a library of functions on a host computer for creating content and controlling the mirror. Integration with
smart phone applications is demonstrated, utilizing the mobile device both for content generation based on various
messages or data, and for content streaming to the MEMS controller via Bluetooth interface. The display unit is highly
resistant to vibrations and shock, and requires only ~1.5W to operate, even with content readable in sunlit outdoor
conditions. The low power requirement is in part due to a vector graphics approach, allowing the efficient use of laser
power, and also due to the use of a single, relatively high efficiency laser and simple optics.
