Abstract: A head-up display (HUD) uses reduced reflectivity projection optics to reduce the harmful effects of intense solar radiation on HUD components. In a HUD generally having a display, a mirror, and a combiner, an image is projected from the display to the combiner via the mirror. The reflectance of the mirror is reduced to prevent high thermal stress on HUD components. The light source is brighter than a conventional backlight, and thus compensates for the reduction in the reflectance of the mirror. Reduced mirror reflectance translates into a reduced thermal load on the display, lens, case, electronics, or wherever the solar radiation is directed.
