Abstract: Segmented displays are provided on an automobile windshield by stacked or linearly arrayed holograms containing separate display segments selectively illuminatable by different wavelengths of light to provide a variable display. Each hologram is edge illuminated by a wavelength which differs from the wavelength used to illuminate adjacent holograms to provide, for example, a seven segment or bar graph display. A second embodiment provides a single hologram containing a seven segment digit with light beams selectively directed on the digits to display desired numerals.
