Abstract

A vehicular display device includes a display unit that displays visible information and a light projection unit that guides light including the visible information displayed on the display unit to a predetermined projection surface, and displaying the visible information as a virtual image. The vehicular display device includes a guide display unit and a guide display control unit. The guide display unit indicates a relationship between at least positions of a first display region in which the virtual image is displayed by projection of the light projection unit and a second display region in which detailed information is displayed. The detailed information has an association with a content of particular information that is displayed on the display unit under a predetermined condition. The guide display control unit controls the guide display unit into a display state when the particular information is displayed on the display unit.

Claims

1. A vehicular display device, including a display unit that displays visible information and a light projection unit that guides light including the visible information displayed on the display unit to a predetermined projection surface, and displaying the visible information as a virtual image, the vehicular display device comprising:

a guide display unit that indicates a relationship between at least positions of a first display region in which the virtual image is displayed by projection of the light projection unit and a second display region in which detailed information is displayed, the detailed information having an association with a content of particular information that is displayed on the display unit under a predetermined condition; and

a guide display control unit that controls the guide display unit into a display state when the particular information is displayed on the display unit.

2. The vehicular display device according to claim 1,

wherein the guide display unit comprises at least one light emitting element for guidance that can be lighted up and turned off by the guide display control unit.

3. The vehicular display device according to claim 2,

wherein the guide display unit comprises a plurality of light emitting elements for guidance that can be lighted up and turned off by the guide display control unit, and

wherein the guide display control unit individually lights up and turns off the plurality of light emitting elements for guidance and displays a flowing state of a direction from the first display region towards the second display region.

4. A vehicular display system comprising:

a first vehicular display device, including a display unit that displays first visible information and a light projection unit that guides light including the first visible information displayed on the display unit to a predetermined projection surface, and displaying the first visible information as a virtual image;

a second vehicular display device displaying more information than the first vehicular display device, as second visible information;

a guide display unit, provided to at least one of a place on the first vehicular display device, a place on the second vehicular display device and a space between the places, and indicating a relationship between at least positions of a first display region in which the virtual image is displayed by projection of the light projection unit of the first vehicular display device and a second display region on the second vehicular display device in which detailed information is displayed, the detailed information having an association with a content of particular information that is displayed in the first display region under a predetermined condition; and

a guide display control unit that controls the guide display unit to a display state when the particular information is displayed on the display unit of the first vehicular display device.

5. The vehicular display system according to claim 4,

wherein the guide display unit comprises a first guide display unit including at least one light emitting element for guidance that is arranged on the first vehicular display device and a second guide display unit including at least one light emitting element for guidance that is arranged on the second vehicular display device, and

wherein the guide display control unit, individually lights up and turns off the light emitting element for guidance of the first guide display unit and the light emitting element for guidance of the second guide display unit, and displays a flowing state of a direction from the first display region towards the second display region.

6. A vehicular display device displaying detailed information on a vehicle as first visible information, the vehicular display device comprising:

a guide display unit that is arranged between a first display region in which the first visible information is displayed and a second display region in which information is displayed as second visible information of a virtual image, and that indicates a relationship between at least positions of the first display region and the second display region, the information displayed in the second display region having an association with the detailed information and more restricted than the detailed information; and

a guide display control unit that controls the guide display unit into a display state when predetermined particular information is displayed in the second display region.

7. The vehicular display device according to claim 6,

wherein the guide display unit includes a plurality of light emitting elements for guidance that can be lighted up and turned off by the guide display control unit, and

wherein the guide display control unit, individually lights up and turns off the plurality of light emitting elements for guidance, and displays a flowing state of a direction from the first display region towards the second display region.

8. The vehicular display device according to claim 6,

further comprising a light reflection plate that is arranged at a position displaced from a windshield of the vehicle towards a vehicle interior,

wherein the detailed information is projected onto the light reflection plate so as to be displayed as a first virtual image, and at the same time, a display state of the guide display unit is projected onto the light reflection plate so as to be displayed as a second virtual image at a position displaced from the first virtual image.
