Abstract

A display device for a vehicle includes: a dial plate having an indicator portion corresponding to vehicle information on a viewing side; an image display panel disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side. A region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate.

First claim

What is claimed is:

1. A display device to be mounted on a vehicle, comprising:
a dial plate having an indicator portion corresponding to vehicle information on a viewing side;
an image display panel that is disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and
a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side, wherein
a region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate,
the reflective portion includes a plurality of reflective elements that reflect the light from the light source to the viewing side, and are arrayed along an extending direction of the light transmissive display plate to configure a pattern,
the reflective portion is one of a plurality of reflective portions to configure the patterns different from each other in the same light transmissive display plate,
in the same reflective portion, each of the reflective elements has a reflection surface facing in the same direction as each other, and the reflection surface of each of the reflective elements faces in different directions between the different reflective portions,
the light source includes a plurality of light emitting portions disposed along an outer edge portion of the light transmissive display plate, and
each of the light emitting portions corresponds to each of the reflective portions, individually, and is disposed at a position of the outer edge portion, which faces the reflection surface of the corresponding reflective portion to emit the light toward the facing reflection surface.

2. The display device according to claim 1 , wherein
the pattern includes an outer peripheral pattern that is linearly formed in a region of the light transmissive display plate, which corresponds to an outer peripheral portion of the indicator portion to border the indicator portion,
an end portion of the outer peripheral pattern extends to a region of the light transmissive display plate, which faces the image display panel, and
the image display panel displays an extended image linearly provided to further extend the end portion of the outer peripheral pattern as the image.

3. A display device to be mounted on a vehicle, comprising:
a dial plate having an indicator portion corresponding to vehicle information on a viewing side;
an image display panel that is disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and
a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side, wherein
a region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate,
the reflective portion includes a plurality of reflective elements that reflect the light from the light source to the viewing side, and are arrayed along an extending direction of the light transmissive display plate to configure a pattern,
the pattern includes a contour pattern representing an exterior contour of a display object, and
the image display panel displays, as the image, an internal image representing an internal state of the display object by superimposing the internal image on the contour pattern.

4. A display device to be mounted on a vehicle, comprising:
an image display panel that luminescently displays an image on a viewing side; and
a light transmissive display plate that includes a reflective portion which is disposed on the viewing side of the image display panel and reflects a light from a light source to the viewing side, wherein
the reflective portion includes a plurality of reflective elements that reflect the light from the light source to the viewing side, and are arrayed along an extending direction of the light transmissive display plate to configure a pattern,
the pattern includes a contour pattern representing an exterior contour of a display object, and
the image display panel displays an internal image representing an internal state of the display object as the image by superimposing the internal image of the display object on the contour pattern.

5. A display device to be mounted on a vehicle, comprising:
a dial plate that displays an indicator portion corresponding to vehicle information on a viewing side;
an image display panel that luminescently displays an image on the viewing side;
a light transmissive display plate that includes a reflective portion which is disposed on the viewing side of the dial plate and the image display panel to reflect a light from a light source to the viewing side; and
a light source controller configured to control the light source on or off, wherein
the reflective portion includes a plurality of reflective elements that reflect the light from the light source to the viewing side, and are arrayed along an extending direction of the light transmissive display plate to configure a pattern,
the pattern includes an outer peripheral pattern that is linearly formed in a region of the light transmissive display plate, which corresponds to an outer peripheral portion of the indicator portion to border the indicator portion,
the light source controller controls the light source on or off to switch the outer peripheral pattern to be in a display state or a non-display state,
an end portion of the outer peripheral pattern extends to a region of the light transmissive display plate, which faces the image display panel,
the image display panel displays an extended image linearly provided to further extend the end portion of the outer peripheral pattern as the image,
the extended image is in a display state on the image display panel when the light source is turned on, and
at least a part of the extended image is in a non-display state on the image display panel when the light source is turned off.

6. The display device according to claim 5 , wherein the light source includes a color light source capable of changing a color of the pattern.

7. The display device according to claim 5 , wherein
the reflective portion is one of a plurality of reflective portions to configure the patterns different from each other in the same light transmissive display plate,
in the same reflective portion, each of the reflective elements has a reflection surface facing in the same direction as each other, and the reflection surface of each of the reflective elements faces in different directions between the different reflective portions,
the light source includes a plurality of light emitting portions disposed along an outer edge portion of the light transmissive display plate, and
each of the light emitting portions corresponds to each of the reflective portions, individually, and is disposed at a position of the outer edge portion, which faces the reflection surface of the corresponding reflective portion to emit the light toward the facing reflection surface.

8. The display device according to claim 5 , wherein
the pattern includes a contour pattern representing an exterior contour of a display object, and
the image display panel displays, as the image, an internal image representing an internal state of the display object by superimposing the internal image on the contour pattern.

9. The display device according to claim 5 , wherein
the reflective portion has a gradation region in which a display luminance of the pattern is changed int
