BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle instrument for displaying a virtual image by reflecting a VFD display or a warning display by a half mirror.

[0002]

2. Description of the Related Art FIG. 2 shows an example of a conventional vehicle instrument using a virtual image display. VFD on top of instrument housing 1
2 is provided, and the front surface of the VFD 2 is covered with a light control film 3 as a light control layer.

A VFD (display unit) is provided inside the housing 1.
The half mirror 4 is provided in a direction of about 45 degrees with respect to the two optical axes, and a warning display unit 5 including an LED, a bulb, and the like is provided on the back surface of the half mirror 4. Then, the light from the VFD 2 is reflected by the half mirror 4 and is emitted to the driver side through the front glass 6 provided on the front surface of the housing 1. Warning display section 5
Is transmitted to the driver side through the half mirror 4 and the front glass 6. That is, the driver views the display of the VFD 2 as the virtual image 2a.

[0004]

However, in the conventional virtual image display vehicle instrument configured as described above, the display of the blue-green pigment appears on a black background, and the display layout and the character Even if the typeface was changed, it did not look very different and had a uniform image.

The present invention has been made to solve the above problems, and has as its object to provide an instrument for a vehicle capable of creating a new display form different from the conventional one.

[0006]

In order to achieve the above object, the present invention provides a vehicle instrument having a display section and a half mirror for reflecting light from the display section. a transparent colored layer which is provided, said Hafumi
And an illumination light source for illuminating the half mirror from the rear side .

[0007]

According to the above arrangement, the half mirror is moved from the back.
Light of the illumination light source for illuminating is colored in any color transmitted through the transparent colored layer, it is possible to color the background. Therefore, the image of the display portion reflected by the half mirror is displayed with the background colored as a background, and a new display form can be formed. Moreover, a transparent coloring layer
Is provided on the back of the half mirror, so it is transparently colored.
Light may be scattered between the layer and the half mirror,
And the inside surfaces of the half mirror facing each other get dirty
Nothing to do. Therefore, light transmittance is improved.
And can maintain the initial transmittance
There is an advantage that you can.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a vehicle instrument according to an embodiment of the present invention;

FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, portions corresponding to those of the conventional example shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.
A VFD (display unit) 2 and a warning display unit 5 are provided on the upper part of the housing 1 of the instrument.

A light control film 7, a color film (transparent colored layer) 8, and a diffusion plate 9 are sequentially laminated on the back surface of the half mirror 4 provided in the housing 1. Furthermore, the housing 1 outside the half mirror 4
A CCT 11 as an illumination light source is provided in 0, and a reflection plate 12 that reflects light emitted from the CCT 11 toward the half mirror 4 is attached in the housing 10. Further, the front glass 6 is made of smoked glass, and has an antireflection treatment 13 on its inner surface.

Next, the operation of this embodiment will be described. VFD2
Light emitted from the warning display unit 5 is reflected by the half mirror 4 and travels toward the driver. At this time, the light control film 3 has an effect of preventing light emitted from the VFD 2 and the warning display unit 5 from illuminating the surroundings. On the other hand, the light emitted from the CCT 11 is made uniform by the diffusion plate 9, is colored to an arbitrary color by the color film 8 constituting the transparent coloring layer, and the direction is regulated by the light control film 7 constituting the light control layer. And CC
The light emitted from T11 passes through the half mirror 4 and
D2 and light emitted from the warning display unit 5 overlap with each other and travel toward the driver.

The light control film 7 provided on the half mirror 4 is provided so that light emitted from the CCT 11 is emitted only toward the front and does not illuminate surrounding components. Further, the anti-reflection treatment 13 applied to the inner surface of the front glass 6 includes the VFD 2, the warning display unit 5, and the CCT.
This is for preventing the light emitted from 11T from being reflected on the front glass 6 and causing an unnecessary image to be displayed. The front glass 6 is made of smoked glass so that internal components are not visible from the outside, and the VFD 2 and the warning display 5
And only the necessary bright light-emitting portion emitted from the CCT 11 is made visible.

According to this embodiment, the background of the virtual image display from the VFD 2 and the warning display unit 5 can be colored, and a new display mode different from the conventional one can be formed. Moreover, the light control film 7 and the color film
The film 8 and the diffusion plate 9 are stacked on the back of the half mirror 4.
Half mirror 4, light control
Film 7, color film 8, and diffusion plate 9 respectively.
The light is scattered between these half mirrors 4
Control film 7, color film 8, and diffusion plate
The inside of 9 facing each other gets dirty
There is no. Therefore, it is possible to improve the light transmittance.
In both cases, the advantage is that the initial transmittance can be maintained.
There is a point.

In the above embodiment, the case where the color film 8 is provided to color the background has been described. However, the light control film 7 may be colored by printing or the like. The background light source may be, for example, an EL or a bulb other than the CCT11. Further, the antireflection treatment of the inner surface of the front glass 6 may be omitted.

[0015]

As it has been described above devised], according to the vehicle instrument of the present invention, an illumination light source for illuminating the half mirror from the back
Of the light is colored in any color transmitted through the transparent colored layer, it is possible to color the background. Therefore, the image of the display portion reflected by the half mirror is displayed with the background colored as a background, and a new display form can be formed. Moreover, the transparent coloring layer
Since it is provided on the back, a transparent coloring layer and a half mirror
Light is scattered between the transparent colored layer and half mirror
Or the inner surfaces of the two facing each other get dirty
Absent. Therefore, it is possible to improve the light transmittance.
First, the advantage that the initial transmittance can be maintained
There is.
