Information display device

1. An information display device that displays information in a vehicle, comprising:

a first information display device that displays image information of a virtual image using reflection from a windshield of the vehicle;

a second information display device that scans the windshield with laser light using a MEMS element to obtain a real image; and

a third information display device using an instrument panel of the vehicle,

a sensor that views movement of a viewpoint of a viewer,

wherein the first information display device includes a virtual image optical system that reflects light emitted from an image display device which displays the image information to the windshield to display a virtual image in front of the vehicle,

wherein the second information display device includes a real image optical system that performs scanning with laser light using a scanning-type mirror element and displays a real image on the windshield,

wherein the third information display device includes a direct-view-type image display device as the instrument panel,

wherein an image display position of the first information display device is in the vicinity of a center of the windshield and an image display position of the second information display device is a lower part of the windshield, and

wherein display positions, display time, and display content of images displayed by the first to third information display devices are changed on the basis of information of the movement of the viewpoint of the viewer by the sensor.

2. The information display device according to claim 1 ,

wherein centers of the image display positions displayed by the first to third information display devices are arranged in the vicinity of a straight line including a central axis of rotation of a steering wheel of the vehicle.

3. The information display device according to claim 1 ,

wherein, in the display of an image based on the virtual image by the first information display device, the virtual image is displayed so as to be superimposed on a real view which is located far from the windshield on which the real image is displayed by the second information display device.

4. The information display device according to claim 1 ,

wherein an image based on the virtual image of the first information display device is displayed so as to be superimposed on a part or all of an image based on the real image of the second information display device.

5. The information display device according to claim 1 ,

wherein a horizontal display dimension on the windshield in the display of an image based on the virtual image by the first information display device which is seen by a viewer through the windshield is less than a horizontal display dimension in the display of the real image by the second information display device.

6. The information display device according to claim 1 , An information display device that displays information in a vehicle, comprising:

a first information display device that displays image information of a virtual image using reflection from a windshield of the vehicle;

a second information display device that scans the windshield with laser light using a MEMS element to obtain a real image; and

a third information display device using an instrument panel of the vehicle,

wherein the first information display device includes a virtual image optical system that reflects light emitted from an image display device which displays the image information to the windshield to display a virtual image in front of the vehicle,

wherein the second information display device includes a real image optical system that performs scanning with laser light using a scanning-type mirror element and displays a real image on the windshield,

wherein the third information display device includes a direct-view-type image display device as the instrument panel,

wherein an image display position of the first information display device is in the vicinity of a center of the windshield and an image display position of the second information display device is a lower part of the windshield, and

wherein an image display range of the second information display device is changed according to an output of a sensor that senses a speed of the vehicle and is displayed on the windshield.

7. The information display device according to claim 6 ,

wherein centers of the image display positions displayed by the first to third information display devices are arranged in the vicinity of a straight line including a central axis of rotation of a steering wheel of the vehicle.

8. The information display device according to claim 6 ,

wherein, in the display of an image based on the virtual image by the first information display device, the virtual image is displayed so as to be superimposed on a real view which is located far from the windshield on which the real image is displayed by the second information display device.

9. The information display device according to claim 6 ,

wherein an image based on the virtual image of the first information display device is displayed so as to be superimposed on a part or all of an image based on the real image of the second information display device.

10. The information display device according to claim 6 ,

wherein a horizontal display dimension on the windshield in the display of an image based on the virtual image by the first information display device which is seen by a viewer through the windshield is less than a horizontal display dimension in the display of the real image by the second information display device.
