摘要:
Head-up displays on motor vehicles often have double images and interfering reflections on the windshield. To avoid these, arrangements of linear polarization filters or shutter foils are suggested, which have particularly high light transmission. Arrangements of filter plates on a combiner inside of the windshield are also advantageous.

The present invention relates to a display device having a transparent display field through which ambient light can pass from the side facing away from an observer to the side facing the observer. Characters and/or symbols can be presented against a light background on the display field. On the side facing the observer, the display field has a light-guide plate 9 of transparent material in which light-dispensing particles 19 are distributed and into which the light from a source of light 12 can be introduced.

An instrument arrangement for an automotive vehicle comprises front and rear housings, and an indicating portion arranged therebetween and having on surface on which luminophors are placed. Within the front housing are arranged a visible light source, and a black light source. The black light source is arranged to be more distant from the one surface of the indicating portion than the visible light source, thus reflecting light of the visible light source toward the indicating portion.

A phosphor indication device suitable for use as a meter of a vehicle including an indication section having a pattern and characters to be indicated which are printed with at least one ordinary paint and at least one paint containing a phosphor differing in color when it is exposed to light capable of exciting the phosphor to emit light in fluorescence from when it is exposed to ordinary light unable to excite the phosphor to emit light. The pattern and characters of the indication section may be illuminated by a light source capable of exciting the phosphor to emit light in fluorescence and at least one light source emitting ordinary light, so that the colors of the pattern and characters can be varied when they are illuminated by light capable of exciting the phosphor to emit light in fluorescence from when they are exposed to ordinary light to enable indication to be given in a characteristic fashion.

A light source is positioned to direct light downward from the cover of a conventional analog or electro-optical watch, indicator gauge, a meter panel directional gauge or ornamentation display of an image, logo or design or other similar articles. These articles are illuminated by the source for viewing in low light or in the dark by an illumination switch to activate said element. The light source is preferably an LED and it is small enough so that when it is off, it is virtually invisible.

The present invention comprises a method and apparatus for providing user selectable multi-color illumination to automotive instrument panel instruments. In one embodiment, an instrument panel or individual instrument is supplied with a plurality of differently colored illumination sources. The intensity of each color is individually controllable, allowing the user to select both intensity and hue of instrument illumination. In one embodiment, an instrument panel illumination system comprises three light sources that produce nominally white light and three associated diffusing filters, one red, one green, one blue. In another embodiment different colors of illumination are provided by light sources producing different colors of light, such as, for example, a plurality of high intensity red, green, and blue light emitting diodes ("LED's"). In one embodiment, a plurality of triplets of red, green and blue high intensity LED's are mounted above a white diffusing filter. In one embodiment, a plurality of colored light sources are mounted in an instrument housing behind the instrument's bezel.

A positioning and navigation system for land vehicles features a simple and memory-conserving route entry method. Routes on maps can be specified by the junctions traversed by the route, so that entering only the junctions in memory uses much less space than prior art digital route storage systems which stored the coordinates of each point along the route. A trip progress information display shows the route vividly by using color or brightness contrast with the rest of the map. Additional direction of travel indications can be given, for example on a Head Up Display reflected off the inside of the windshield within the operator's field of view or by acoustic signals or speech-synthesized announcements. This results in particularly easy-to-follow guide to the driver or operator. Head-up displays on motor vehicles often have double images and interfering reflections on the windshield. To avoid these, arrangements of linear polarization filters or shutter foils are suggested, which have particularly high light transmission. Arrangements of filter plates on a combiner inside of the windshield are also advantageous.

A monitor display unit having a hologram dry plate, formed by coating a glass base plate with sensitive material, and installed in an instrument panel of a vehicle. On the hologram dry plate are multiply recorded light interference fringes of three-dimensional images of the vehicle seen from the front and the rear of the vehicle. Two image reproduction lamps for illuminating reproduction light toward the hologram dry plate are provided on the right front and the left front of the hologram dry plate. When one image reproduction lamp is lighted, one three-dimensional image is reproduced on the hologram dry plate. Light emission diodes are provided rearward of the hologram dry plate so as to correspond to the positions of lamps on the three-dimensional image. The light emission of the light emission diodes is recognized through the hologram dry plate. A control circuit operates one of the image reproduction lamps to reproduce one three-dimensional image indicating the positions of the monitored lamps and to light the light emissions diodes corresponding to the monitored lamps on the three-dimensional image.

A figure defining system (39, 43, 46, 57) defines a first figure as a pointer (43) on a background plate (39) and a second figure as a character plate (46) with characters and divisions, a figure illuminating system (39a, 43a, 47, 49, 55a, 51, 53) includes a rear light transmitting plate (47) for illuminating the pointer (43) as a figure element of the first figure to be visible, the rear light transmitting plate extending along a first plane, a top light transmitting plate (49) for illuminating the characters and divisions as figure elements of the second figure to be visible, the second light transmitting plate extending along a second plane crossing the first plane, and a common light source (51) disposed in a corner chamber partially defined by an end face of the rear light transmitting plate and an end face of the top light transmitting plate, and a half mirror (41) arranged between the first and second planes for displaying a combination of an optical image of the first figure, as it is transmitted through the half mirror, and an optical image of the second figure, as it is reflected on the half mirror, to have images of the figure elements combined to be visible in a display field.
