Abstract
An improved head up display utilizes a prism to direct the image of a display CRT upward to a semi-transparent combiner element, permitting a substantially smaller vertical profile of the overall structure. An image is presented to a viewer that appears to be at infinity and is indistinguishable from the exterior scene as viewed from that vantage point. In alternative embodiments, the display unit can utilize more than one prism with one or more combiner elements to increase the vertical height of the viewed image of the CRT while dramatically reducing the vertical space required for the display unit in an instrument panel.
