[overall structure]
FIG. 1 is a schematic exploded perspective view of a vehicle display device (hereinafter referred to as a display device 100). The display device 100 will be described with reference to FIG.

  The display device 100 includes a display panel 200 and analog meters 300 and 500. The display panel 200 includes a display surface 210. The display panel 200 displays an image on the display surface 210. The display panel 200 may be a liquid crystal display that drives liquid crystal and displays an image. Alternatively, the display panel 200 may be a plasma display using plasma emission. Further alternatively, the display panel 200 may be an organic EL display using an organic EL (electroluminescence) element. The principle of this embodiment is not limited to a specific type of display panel 200.

  The image may include information regarding a vehicle on which the display device 100 is mounted. As the information regarding the vehicle, for example, at least one of vehicle state information indicating the state of the vehicle, traveling information regarding the traveling state of the vehicle, and environmental information regarding the environment in which the vehicle travels can be employed. As the state information, for example, information indicating the remaining amount of fuel, the temperature of the radiator, the lighting state of the headlight, and the like can be adopted. As the travel information, for example, the travel speed of the vehicle, the engine speed, and the like can be adopted. As the environmental information, for example, legal speed determined for the road on which the vehicle is traveling, information on the outside temperature and weather can be adopted.

  Similar to analog meters mounted on known vehicles, analog meters 300 and 500 provide information on the vehicle on which display device 100 is mounted (for example, vehicle speed, engine speed, water temperature, and fuel remaining amount). , May be given to the driver.

  The analog meter 300 is disposed on the left side of the display panel 200 and includes a C-shaped ring 310 and an indicator hand 320.

  The indicator needle 320 rotates within a region surrounded by the C-shaped ring 310. In the region surrounded by the C-shaped ring 310, an index (for example, a scale line or a number) representing a physical quantity related to the running state of the vehicle on which the display device 100 is mounted is displayed. The presentation of the indicator may depend on various techniques used for analog meters mounted on known vehicles.

  Analog meter 500 is arranged on the right side of display panel 200, and similarly to analog meter 300, information indicating the traveling state of the vehicle on which display device 100 is mounted (for example, the speed of the vehicle, the number of revolutions of the engine, the water temperature and the fuel). The remaining information of the analog meter 300 is given to the driver.

  Analog meter 500 includes a C-shaped ring 510 and indicator hands 520 and 530.

  The indicator needles 520 and 530 rotate in the area surrounded by the C-shaped ring 510, respectively. In the region surrounded by the C-shaped ring 510, the display plate 400 may be drawn with an index (for example, a scale line or a number) representing a physical quantity related to the running state of the vehicle on which the display device 100 is mounted.

  The display device 100 further includes a display plate 400. The display board 400 is disposed between the display panel 200 and the analog meters 300 and 500. The display panel 400 includes a flat first surface 411 and a flat second surface 412. The first surface 411 faces the display panel 200. The analog meters 300 and 500 are attached to the second surface 412 opposite to the first surface 411.

  The display panel 400 is provided with a display area 421 that substantially matches the display surface 210 of the display panel 200 in size and shape, and a surrounding area 422 that is an area outside the display area 421.

  For example, the display area 421 may have a higher optical transmittance than the surrounding area 422. Video light emitted from the display surface 210 of the display panel 200 propagates from the first surface 411 to the second surface 412. Thereafter, the image light is emitted from the display area 421 of the second surface 412.

  The display device 100 further includes a ring body 600. The ring body 600 includes a ring member 610 and a translucent ring 620. The translucent ring 620 is disposed in the ring member 610. Since the display panel 200 displays a meter image in the ring body 600, the translucent ring 620 overlaps the meter image. The driver can see the meter image through the translucent ring 620. The translucent ring 620 cooperates with the ring member 610 to contribute to providing a three-dimensional visual impression to the driver.

  The display device 100 further includes a drive unit 700, a meter vessel 810, and a protective plate 820. The indicator hand 320 of the analog meter 300 and the indicator hands 520 and 530 of the analog meter 500 are mechanically connected to the drive unit 700 through the display board 400.

  The drive unit 700 rotates the indicator hands 320, 520, and 530. For the connection between the drive unit 700 and the indicator hands 320, 520, and 530, various techniques used in known vehicles may be used. Therefore, the principle of the present embodiment is not limited to a specific connection technique between the drive unit 700 and the indicator needles 320, 520, and 530.

  The driving unit 700 may include a circuit (not shown) that generates an image signal for driving the display panel 200. The image signal is output from the drive unit 700 to the display panel 200. The display panel 200 may display a meter image according to the image signal.

  The drive unit 700 may include a drive motor (not shown) that drives the indicator hands 320, 520, and 530. The driving unit 700 can include various electric circuits, driving devices, and optical devices for operating the display device 100. The principle of this embodiment is not limited to a specific structure of the drive unit 700.

  The meter vessel 810 is a cylinder that defines a space in which the display panel 200, the ring body 600, the analog meter 300, the analog meter 500, the display board 400, and the drive unit 700 are accommodated. The protection plate 820 closes the opening of the meter vessel 810. The display panel 200, the ring body 600, the analog meters 300 and 500, and the display plate 400 are disposed between the drive unit 700 and the protection plate 820 in the meter vessel 810.

  The protection plate 820 is transparent as a whole. Accordingly, the image light generated by the display panel 200 can reach the protection plate 820 through the display plate 400 and then can enter the eyes of the driver. The protective plate 820 may be subjected to an optical process for suppressing reflection. In this case, the driver can satisfactorily visually recognize the image displayed on the display panel 200 without being hindered by the reflection on the protective plate 820.

  FIG. 2 is a schematic side view of the display device 100.

  As shown in FIG. 2, the display panel 200 may be in close contact with the first surface 411. Alternatively, a slight gap may be formed between the display panel 200 and the first surface 411. Since the display panel 200 is very close to the first surface 411, the driver displays that the image displayed on the display panel 200 is displayed in the display area 421 of the second surface 412 from which the video light is emitted. It becomes easier to perceive.

  Since the driver visually recognizes that the analog meters 300 and 500 are attached to the second surface 412 on which the image is displayed, the display device 100 is visually connected between the analog meters 300 and 500 and the display panel 200. Integrity can be maintained.
