ABSTRACT:
An improved hologram display panel for a vehicle is provided. Sensors can monitor the operating characteristics of the vehicle and virtual images of indicators can be realized by the illumination of holographic images that are contained in substantially transparent hologram members laminated to the surface of the windshield. The holographic images are virtual image displays that can appear offset from the windshield to accommodate the vision of the driver. A hologram barrier means may be provided to prevent activation of the hologram display by ambient light.
