Abstract: A virtual image display system for displaying a relatively large virtual image to a user derived from a relatively small image source. A lens group is provided for amplifying an image provided by the image source. A plurality of reflecting elements are provided for magnifying the image provided by the lens group and for displaying the relatively large virtual image. Several embodiments are provided that include on-axis and off-axis reflecting versions, and a holographic virtual image version. Conventional lenses and reflecting optics are used to provide the on- and off-axis versions of the system, while a holographic reflecting element is used to provide a holographic virtual image. A window element may also be employed to minimize ambient reflection viewed by the user and eliminates ambient reflection to reduce the user's eye fatigue. The display system improves a user's viewing comfort by positioning the image at a distance matching the visual requirements of the user's eye.

Abstract: A display device having a plurality of information symbols for each light source such as an LED chip. The upper surface of each LED chip is divided into several light-emitting areas by a patterned array of electrically isolated, spaced electrodes. The LED chips are mounted to a substrate and can be selectively activated by a beam lead tape, which is also mounted to the substrate. A cover for the display forms thin, reflective light channels, each of which extends laterally from a light-emitting area to one or more optical openings in the cover. The optical openings form the information symbols. The lateral channels direct emissions from the LED chip to the openings via multiple reflection and optical dispersion to uniformly illuminate the openings.
