Abstract
Abstract An improved, relatively thin panel display includes a housing member supporting a hologram containing a holographic image of predetermined indicia that can be appropriately illuminated to appear to the observer as being positioned at a location offset from the actual location of the hologram panel display member. The hologram member can be illuminated by either back lighting, front lighting, or side lighting with the use of either transmission or reflective holographic images. One embodiment of the invention can be combined with a steering wheel with the virtual image of the indicia being located at a sufficient depth to enable the eyes of the viewer to focus comfortably on the panel indicia information.
