Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited by the following embodiments. In addition, the dimensional relationship (length, width, etc.) in each drawing does not reflect the actual dimensional relationship.

FIG. 1 is a schematic diagram showing a schematic configuration of a vehicle display device 10 according to the present embodiment, and reference numeral E in the drawing indicates the eyes of a passenger. As shown in FIG. 1 , the vehicle display device 10 includes a front windshield 20 , a camera 30 , and a projector (projection mechanism) 40 . The windshield glass 20 has a display area 20a for displaying information. The camera 30 is installed in the front part of the vehicle interior 3, specifically, in a position in front of the driver's seat (near the steering wheel 5) where the frontal portrait of the passenger in the driver's seat can be captured. The projector 40 is installed in front of the driver's seat (near the steering wheel 5 ) at a position where the image can be projected on the display area 20a. However, as another embodiment, the projector 40 may be installed in the rear or the top of the vehicle interior 3 .

In the present embodiment, the front windshield 20 includes a light-adjusting material layer 23, and substantially the entire area of the front windshield 20 is set as the display area 20a, which can be switched between a transparent state and a mirror state. However, as another embodiment, only a part of the area of the front windshield 20 may be set as the display area 20a. Hereinafter, the structure of the front windshield 20 will be described in detail.

2A , 2B and 2C are schematic views showing the structure of the front windshield 20 , in each of the drawings, the left side of the drawing is the vehicle exterior 2 , and the right side of the drawing is the vehicle interior 3 . As shown in FIGS. 2A to 2C , the front windshield 20 includes an outer glass 21 , an inner glass 22 , a light-adjusting material layer 23 , and a display formed on the back surface of the light-adjusting material layer 23 (the side facing the vehicle interior 3 ) Material layer 24 . These materials are laminated in the order from the second side outside the vehicle compartment to the third side inside the vehicle compartment in the order of the outer glass 21 , the light adjustment material layer 23 (and the display material layer 24 ), and the inner glass 22 to constitute the front windshield 20 . In addition, in the present embodiment, colorless and transparent glass is used for both the outer glass 21 and the inner glass 22 .

The light-adjusting material layer 23 is composed of a known light-adjusting mirror film, and can be switched between a transparent state and a mirror state by controlling the polarity of the voltage applied thereto. In the mirror state, the dimming material layer 23 can not only reflect infrared light, but also reflect external light such as visible light. In the present embodiment, the light-adjusting material layer 23 is spread over the entire front windshield glass 20 , so the entire front windshield glass 20 can be switched between a transparent state and a mirror state. Here, by controlling the polarity of the voltage applied to the light-adjusting material layer 23 by a switch control device (not shown), the light-adjusting material layer 23 is brought into a transparent state or a mirror state. In FIGS. 2A , 2B and 2C , those with slashes on the dimming material layer 23 indicate that the dimming material layer 23 is in a mirror state ( FIGS. 2A and 2B ), and those without slashes on the dimming material layer 23 indicate dimming The material layer 23 is in a transparent state (FIG. 2C).

The display material layer 24 formed on the back surface of the light-adjusting material layer 23 is made of, for example, a reflective film or the like, and the image projected by the projector 40 can be displayed on the display material layer 24 . In this embodiment, the display material layer 24 spreads over the entire front windshield glass 20 , and thus, the entire front windshield glass 20 can be the display area 20a. In FIGS. 2A , 2B and 2C , dots on the display material layer 24 indicate a state in which an image is projected on the display material layer 24 ( FIGS. 2B and 2C ), and those without dots on the display material layer 24 indicate the display material layer 24 The state with no image projection on it (Fig. 2A).

Based on the above structure, for example, when the vehicle is parked, the front windshield 20 can prevent the outside light EL (indicated by the arrow in the figure) from entering the vehicle interior 3 by making the light-adjusting material layer 23 into a mirror state as shown in FIG. 2A . It can prevent the temperature of the vehicle interior 3 from rising during parking. In this case, if there is no information to be displayed or the like, there may be no display on the display material layer 24 as shown in FIG. 2A .

If the passenger needs to perform operations such as dressing, as shown in FIG. 2B , after making the light-adjusting material layer 23 into a mirror state, the projector 40 can project his own image captured by the camera 30 on the display material layer 24 , Therefore, the front windshield 20 can function as a vanity mirror while preventing the outside light EL from entering the vehicle interior 3 .

Further, if information needs to be displayed during driving, as shown in FIG. 2C , when the light-adjusting material layer 23 is in a transparent state, the projector 40 can project information (text images, etc.) on, for example, the front windshield 20 . On the display material layer 24 in the edge area, in this way, passengers can see the scenery outside the car through the transparent dimming material layer 23, and simultaneously see the information displayed on the display material layer 24 (such as vehicle speed etc.) ).

Furthermore, during driving, the projector 40 may project the scene behind the vehicle 1 captured by another camera (not shown) on the upper portion of the front windshield 20 (corresponding to the function of a conventional rearview mirror).

As shown in FIG. 1 , the camera 30 is installed on the steering column 6 that supports the steering wheel 5, and as shown by the broken line arrow, takes pictures from the front of the passenger in the driver's seat through the opening 5a of the steering wheel 5 (see FIG. 3 ). the passenger. In addition, the camera 30 transmits the captured video as image information to the projector 40 at any time (see arrow 31 in FIG. 1 ).

FIG. 3 is a schematic diagram showing a use state of the vehicle display device 10 . As shown in FIG. 3 , the projector 40 is installed in the dashboard 4 . The projector 40 is connected to the camera 30 in a wired or wireless manner, so as to receive image information sent by the camera 30 . When the display area 20a (the entire front windshield 20 in this embodiment) is switched to the mirror state, the projector 40 projects the image captured by the camera 30 on the display area 20a from the window portion 4a of the instrument panel 4 (see Arrow 41 in Figure 1).

In addition, the projector 40 includes a trimming unit (not shown) that trims the image captured by the camera 30 . The trimming performed by the trimming unit includes, for example: (1) inverting and correcting the image of the passenger captured by the camera 30 to make it the same as the image reflected by the mirror; (2) adjusting the vertical and horizontal dimensions of the projected image The size ratio is adjusted and corrected to suppress the distortion of the projected image; (3) The passenger's projected image is enlarged and adjusted so that the passenger can see his head portrait more clearly.

Further, for example, the dashboard 4 is provided with a switch control device (not shown) for controlling state switching of the display area 20a, switching of the camera 30, projection operation of the projector 40, and the like. The passenger on the driver's seat can switch the display area 20a between the transparent state and the mirror state by operating the buttons on the switch control device, etc.; the camera 30 can start shooting or stop shooting; the projector 40 can start or stop projecting. , and can adjust the size of the projected image.

FIG. 4 is a schematic diagram for explaining the use state of the vanity mirrors 109 and 110 of the related art. As shown in FIG. The mirror surface of the vanity mirror 109 is small, so the range of the mirror image of the passenger that can be reflected is small, and the passengers often cannot get effective assistance when they perform operations such as dressing in the vehicle interior 103 .

In addition, as shown in FIG. 4 , a vanity mirror 110 is also attached to the interior roof panel 107 . Compared to the vanity mirror 109 mounted on the sun visor 108, the vanity mirror 110 is closer to the passenger and is located above the passenger's head. Therefore, as shown by the hollow arrows in FIG. 4 , when using the vanity mirror 110 , the passenger needs to look up, and thus cannot see his frontal head portrait in the vanity mirror 110 .

On the other hand, as shown in FIG. 3 , the vehicle display device 10 of the present embodiment can project the image of the passenger captured by the camera 30 on a very large display area 20a, and the image of the passenger is projected directly in front of the passenger. On the front windshield 20, the passenger can see the front face of himself displayed in the front in a natural riding posture.

Here, since the projector 40 projects the passenger image on the display area 20a of the inclined front windshield 20 (as indicated by the mark A in FIG. 1 ), the mark in FIG. 3 will be displayed on the display area 20a In the projected image shown in A, the trimming unit of the projector 40 adjusts and corrects the aspect ratio of the passenger image captured by the camera 30. Therefore, in the field of view of the passenger indicated by the mark B in FIG. Aspect ratio undistorted image indicated by mark B in FIG. 3 . Therefore, according to the vehicle display device 10 of the present embodiment, the passenger can see an enlarged and undistorted image of himself displayed ahead.

In this way, according to the vehicle display device 10 of the present embodiment, since the range to be photographed for the passenger is greatly increased, it is possible to obtain effective assistance when dressing or the like in the vehicle interior 3, and in particular, the passenger can You can see your own frontal head in the riding posture, and you do not have to look up like the vanity mirror 110 installed on the roof panel of the car, so the convenience of use is greatly improved.
