HEAD-UP DISPLAY SYSTEM

摘要

The present invention relates to a head-up display system which includes an element thereof. The element is attached to, for example, an automobile windshield so as to project light rays carrying images of display information onto the element from a luminous source in a car. The element includes first and second reflection layers. The first layer is directly attached to the windshield and has a relatively uniform reflectance throughout visible light spectrum. The second layer is directly formed on the first layer and has a selective reflection against incident visible light of wavelengths in the range from about 500 nm to about 600 nm. Thus, the light rays from the luminous source are displayed on the first and second layers in different colors.
