Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted image display device mounted on a vehicle.

[0002]

2. Description of the Related Art In recent years, in vehicles, especially passenger cars, along with a television broadcast receiving function, a navigation function for informing location guidance information such as the current location thereof, and a traffic information service function for receiving road information such as road congestion status. Etc. are being added, that is, intelligence and computerization are being promoted. In order to realize the intelligence and informatization of this passenger car, the vehicle is equipped with an image display device for displaying an image by each of the above-mentioned functions.

As this vehicle-mounted video display device, a video signal supply means for supplying a video signal having a function such as a navigation function, an information service function, and a television broadcast receiving function, and one end thereof is electrically connected to the video signal supply means. ,
Some include a connection means for deriving a video signal from the video signal supply means, and a liquid crystal display panel connected to the other end of the connection means for displaying a video corresponding to the video signal.

The in-vehicle image display device is classified into two types, a dashboard accommodating type and an arm mounting type, depending on the mounting structure of the liquid crystal display panel.

Next, the dashboard accommodating type and the arm mounting type will be described with reference to the drawings. FIG. 9 is a perspective view for explaining a conventional dashboard accommodating vehicle-mounted image display device, and FIG. 10 is a perspective view for explaining a conventional arm-mounted vehicle-mounted image display device.

In the vehicle-mounted video display device of the dashboard accommodating type, as shown in FIG. 9, the liquid crystal display panel 1 is accommodated in the dashboard 2 so that it can be pulled out to the outside, and the liquid crystal display panel 1 is pulled out to the outside. Sometimes the screen of the liquid crystal display panel 1 is oriented in a direction visible to the driver.

On the other hand, in the arm-mounted video display device for vehicle, as shown in FIG. 10, the arm member 4 having the platform 3 at the tip is mounted in the vehicle, and the cloud of the arm member 4 is mounted. Fix the liquid crystal display panel 1 on the platform 3 and mount the platform 3
The orientation of the screen of the liquid crystal display panel 1 is adjusted to a predetermined direction by.

However, in the former vehicle-mounted image display device,
Since the liquid crystal display panel 1 is oriented in a direction that can be confirmed by the driver in the driver's seat, other passengers, for example, passengers in the passenger seat and passengers in the rear seat can fully view the screen of the liquid crystal display panel 1. It is difficult to do so, and other passengers cannot view the image displayed on the liquid crystal display panel 1 without disturbing the driving operation of the driver. Further, in a situation where the driver cannot fully check the image displayed on the liquid crystal display panel 1, other passengers cannot provide the driver with information obtained from the image while watching this image.

On the other hand, in the latter vehicle-mounted image display device, the orientation of the screen of the liquid crystal display panel 1 is adjusted by the platform 3 of the arm member 4, so that the screen of the liquid crystal display panel 1 is directed toward other passengers. Therefore, other passengers can watch the image displayed on the liquid crystal display panel 1 without hindering the driving operation of the driver. However, since the liquid crystal display panel 1 is fixed to the platform 3 of the arm member 4, the space inside the vehicle is reduced by the liquid crystal display panel 1,
The accommodation capacity is inferior to that of the former vehicle-mounted image display device.

[0010]

As described above, in the conventional accommodation type in-vehicle image display device, an image displayed on the liquid crystal display panel by another passenger without disturbing the driving operation of the driver is displayed. You cannot watch it. On the other hand, in the conventional arm-mounted in-vehicle image display device,
Although other passengers can view the image displayed on the liquid crystal display panel without hindering the driver's driving operation, the accommodation property is inferior to the accommodation property of the former vehicle-mounted image display device.

In order to solve the above-mentioned problems, the present invention provides an in-vehicle image display device which is excellent in accommodation and allows other passengers to view an image without disturbing the driving operation of the driver. The purpose is to

[0012]
