Automotive head-up display

An automotive head-up display, also known as an automotive heads-up display or auto-HUD, is a transparent display that presents data in an automobile without requiring a driver to look away from his usual viewpoint. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. At this time, there are three different approaches to OEM HUDs in automobiles. The first is to treat the back of the windshield in such a way that an image projected onto it will reflect to the driver. The second is to have a small combiner that is separate from the windshield. Combiners can be retracted. The third is to laminate a transparent display in between layers of the windshield glass.
