Problems solved by technology

Here, when the required information and the gaze information are different, the effectiveness of the vehicle information decreases
[0008] Therefore, if the virtual image display in the display screen area is linked with the real image display in the instrument part, it will be difficult for the user to notice the timing of the linkage in the future.
As a result, the necessary information is not noticed by the user, which may reduce the reportability of the vehicle information provided by the linkage.

no. 1 approach

[0041] Such as figure 1 As shown, the display device 1 for a vehicle is mounted in front of a driver's seat in a vehicle 2 . The vehicle display device 1 displays vehicle information related to the vehicle 2 so that a user sitting in the driver's seat can visually recognize it. The vehicle display device 1 has a first display unit 10 , a second display unit 20 , a light emitting unit 30 , and a control unit 40 . In addition, in the following description, upward, downward, and sideways refer to upward, downward, and lateral sides in the vehicle 2 on a horizontal plane, respectively.

[0042] Such as Figure 1~4 As shown, the first display unit 10 is housed in a hood 4 formed on the instrument panel 3 in front of the driver's seat in the vehicle 2 . The first display unit 10 has a display panel 12 made of, for example, a liquid crystal panel or an organic EL panel. In the display panel 12 , a substantially rectangular first display portion 122 is formed on the inside of the ...

no. 2 approach

[0107] The second embodiment is a modified example of the first embodiment. In the guidance operation mode Md of the second embodiment, the control unit 40 controls each of the adjacent light sources 340 and each of the separated light sources 360, such as Figure 20 In the figure (a), (b), (c), (d), (e), (f), (g) shown in order, each light emitting area 2346, 2366 is changed.

[0108] Specifically, in each adjacent light guide body 342 , the size of the adjacent light emitting region 2346 gradually increases and then gradually decreases in the guiding direction Dd from the first display portion 122 side to the second display portion 222 side. At this time, especially in each adjacent light guide body 342, the size of the adjacent light emitting region 2346 is changed from the adjacent position Pa Figure 20 The lower end of (a) to Figure 20 The upper end of (c) temporarily increases. And in each subsequent adjacent light guide body 342, corresponding to the expansion of t...

Abstract

The invention relates to an on-vehicle display device. The on-vehicle display device is provided with: a first display unit (10) that displays a real image of first information (124) on a first display part (122); a second display unit (20) that, by projecting an optical image onto a second display part (222) that is arranged above the first display part and that transmits outside images, displaysa virtual image of second information (224) on the second display part; an optical unit (30) that is arranged so as to be laterally adjacent to the first display part and that forms light-emitting regions (346, 366); and a control unit (40) that, during a linking period during which the virtual-image display of the second information is being linked to the real-image display of the first information, causes the light-emitting regions to change in a guidance direction (Dd) that goes from the first display part toward the second display part.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2015-138055 filed on July 9, 2015, and uses the content thereof here. technical field [0002] The present disclosure relates to a vehicle display device that displays vehicle information related to a vehicle. Background technique [0003] Conventionally, a display device for a vehicle that displays vehicle information on a first display unit and a second display unit is known. [0004] Specifically, in the vehicle display device disclosed in Patent Document 1, generally, a display screen area serving as a second display unit through which an external image is transmitted is disposed above an instrument unit that displays vehicle information in a real image. By projecting the optical image onto the display screen area, the virtual image displays vehicle information. [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-218671 [0006] In the display device for a vehicle disclosed in Pat...
