Abstract

PURPOSE:To develop a magnified remote display device for a vehicle to extend a display area of a magnified display virtual image and improve the visibility of the magnified display virtual image. CONSTITUTION:The total display area of a magnified display virtual image 6 seen from a visual point through a display opening 5 is extended to single eye display areas D1, D2 made on both left and right sides of a both eye display area A. Consequently, as a display area of the magnified display virtual image can be extended, the visibility of display virtual image is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
For example, the present invention relates to an enlarged distant display device for a vehicle that displays vehicle speed, engine speed, and other information.

[0002]

2. Description of the Related Art As a conventional enlarged distance display device for a vehicle of this type, there is, for example, a structure as shown in FIG. That is, this device is, for example, a self-luminous display 1 for displaying information such as display scales such as vehicle speed and engine rotation, water temperature display, fuel amount display, and a half for reflecting and diverting the display information by this display 1. It has a mirror 2 and a concave mirror 3 for enlarging and displaying the reflection image reflected by the half mirror in the direction of the driver's eye point P. The display by the display is reflected by the half mirror 2 and then by the concave mirror 3. The display virtual image 4 enlarged by the concave mirror is visually confirmed by the driver.

In this way, the display position of the display virtual image 4 which is enlarged and displayed is, for example, about 300 mm far (front of the driver) from the display position of the vehicle instrument (the position substantially equivalent to the installation of the half mirror 2). Therefore, while driving the vehicle,
Move the line of sight from the front of the vehicle to the display virtual image 4,
The visual recognition speed at the time of visually recognizing the display virtual image can be shortened, thereby improving the visibility of the display and the safety of driving.

The size of the display virtual image 4 is set as shown in FIG.
As shown by, when viewing the display virtual image 4 seen through the display opening 5 provided in the instrument panel in the front direction from the display opening 5 with both eyes P1 and P2 of the driver, The size of the display virtual image 4 is set so that the edges of the display virtual image 4 are not hidden by the edges of the display opening 5, that is, visible in the binocular display area A that can be viewed by both eyes at the same time. Is.

[0005]

However, in such a conventional vehicular magnified far display device, as the distance between the display opening 5 and the display virtual image 4 increases, as shown in FIG.
, The non-display area B1 or B2 seen by one eye P1 or P2 gradually expands, so that the display virtual image 4 area is smaller than the display opening 5 area due to the occurrence of the one-eye display area, and the display virtual image There was a problem that the display quality of 4 was impaired.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and the size of a display virtual image seen through a display aperture is set to a monocular display region rather than a binocular display region. To increase the virtual image display and the accompanying visual quality.

Further, in the present invention, the display form of the virtual image display is such that main display information such as vehicle speed, engine speed, water temperature, fuel amount, etc. is displayed within the binocular display area, and other display information such as air conditioner, audio, gradient Auxiliary display information such as display is displayed in a non-display area that occurs in both left and right directions than the binocular display area, and in particular, the virtual image display, which is the main display information, can be enlarged to improve the visibility of the main display information. It is to greatly improve.

[0008]

The present invention will be described in detail below with reference to the embodiment shown in FIG.

Similar to the above description, P1 and P2 indicate eye points of both eyes of the driver, and 5 indicates a display opening formed in the instrument panel. Reference numeral 6 is an enlarged display virtual image in which the display by the self-luminous display described in the conventional example is reflected and enlarged by a half mirror and a concave mirror. The entire display area C (display size) of the enlarged display virtual image 6 is When a person views the magnified display virtual image 6 through the display opening 5, the magnified display virtual image 6 is displayed on both monocular display areas D1, D.
The size of the display or the magnifying power of the concave mirror is set so as to reach within 2.

That is, although the size of the display virtual image in the related art is set so as to be within the binocular display area A,
In the present embodiment, the enlarged display is performed so as to extend to both the one-eye display areas D1 and D2.

In the present embodiment, the magnified display virtual image 6 covering both of the one-eye display areas is displayed in the center of the binocular display area A, for example, vehicle speed, engine speed, water temperature, fuel amount, etc. Display information of high importance when driving,
Further, in the one-eye display areas D1 and D2 which are generated in the left-right direction from the binocular display area A, a display device is set so as to display display information such as an air conditioner, an audio, and a gradation that are less important. It is what

As described above, in the enlarged distant display device according to this embodiment, the entire display area C including the binocular display area A and the monocular display areas D1 and D2 formed on both sides of the area A is enlarged. Since the size of the magnified display virtual image 6 is set so that the display virtual image 6 is displayed, the non-display areas B1 and B2 formed on the left and right side edges of the display virtual image in the conventional display device are eliminated. Since it is eliminated and becomes a display area, the enlarged display virtual image 6 can be made even larger to give a wide feeling, and thus the visibility can be improved.

Further, the binocular display area A of the enlarged display virtual image 6
Display information of high importance is displayed on the left and right sides of the binocular display area A.
Is designed to display less important information, it is possible to increase the size of the particularly important display, which improves the visibility of the highly important display and improves driving safety. The nature is also enhanced.

[0014]

As described above, according to the present invention, the display device is arranged in front of the concave mirror, and the display image by the display device is made into the enlarged display virtual image behind the concave mirror, and the enlarged display virtual image is displayed from the display opening. In a magnified far display device for a vehicle which is seen through and is viewed in the binocular display area A, an entire display area C of a magnified display virtual image 6 viewed through the display opening from a viewpoint is provided on both left and right sides of the binocular display area A. Since it is the vehicle enlarged distant display device in which the generated one-eye display regions D1 and D2 are widened, the display area of the enlarged display virtual image 6 can be enlarged according to this, and the conventional non-display region is eliminated. By doing so, the visibility of the display can be improved.

Further, according to the present invention, the enlarged display virtual image 6
Display information of high importance in the binocular display area A of
Further, by displaying the less important information in the one-eye display areas D1 and D2 formed on both the left and right sides of the binocular display area A, the display information having the higher importance can be displayed further enlarged. The visibility of highly important displays is further improved and driving safety is enhanced.
