(Embodiment 1)
[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 vehicle 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 employed. 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 needle 320 (an example of a pointer).

  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 (an example of a pointer).

  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. 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.

[screen structure]
FIG. 3 is a diagram illustrating an example of the configuration of the display device 100 according to the first embodiment. The display device 100 is partitioned so that the area is partitioned by the display board 400, has an oblong display board area 410 (an example of a meter panel) that is long in the horizontal direction, and is attached so that the display board area 410 is located on the dashboard of the vehicle It has been. Specifically, the display panel region 410 is attached to a lower portion of the hood HOD that protrudes so as to block outside light incident from the windshield.

  A display surface 210 of the display panel 200 is disposed at the center of the display panel region 410. The display surface 210 has a rectangular shape that is long in the horizontal direction. The ring body 600 is attached so that the center is located at the center of the display surface 210, for example.

  The display surface 210 displays a meter image SCI (an example of a first meter image) in the ring body 600. In the example of FIG. 3, a speedometer image indicating the traveling speed of the vehicle is employed as the meter image SCI. The ring body 600 includes a circular ring member 610 and a donut-shaped translucent ring 620 attached along the inner periphery of the ring member 610.

  The meter image SCI is displayed on the display surface 210 so as to be fitted in the translucent ring 620, and includes an index image 211 and a pointer image 212. The index image 211 is arranged radially at equal intervals and includes a plurality of scale lines indicating the traveling speed. In the example of FIG. 3, a scale line indicating the travel speed “0” is arranged at the bottom of the meter image SCI, and 15 scale lines indicating the travel speed “0” to the travel speed “280” in increments of 20 km / h. Are arranged so as to surround the center of the meter image SCI. The index image 211 includes 15 numerical images indicating the traveling speed corresponding to the 15 scale lines. The pointer image 212 has a needle-like shape extending in the radial direction of the meter image SCI with the center of the meter image SCI as a fulcrum. The pointer image 212 is rotated and displayed within a range of travel speed “0” to travel speed “280”. Hereinafter, in the meter image SCI, an area where the pointer image 212 is rotated and displayed is described as a “movable area”. Further, an area other than the movable area in the meter image SCI is described as a “margin area SCIA”. In the example of FIG. 3, in the meter image SCI, when the lowermost part is 0 degree and the angle is defined clockwise, a fan-shaped area from about 0 degree to about 270 degrees becomes a movable area, and about 270 degrees to about 360 degrees. The fan-shaped area up to is the blank area SCIA.

  Specifically, the pointer image 212 includes a circular image 212c provided on the fulcrum side, and extends from the circular image 212c in the radial direction of the meter image SCI.

  In the example of FIG. 3, the graduation line is included in the meter image SCI, but it may be arranged on the translucent ring 620. However, when the scale line is displayed as an image, it is easy to change the use for each destination.

  An analog meter 300 is disposed on the left side of the display surface 210, and an analog meter 500 is disposed on the right side of the display surface 210. The analog meter 300 is composed of a mechanical pointer type meter. The analog meter 300 corresponds to an example of a first pointer type meter.

  The analog meter 300 includes an arc-shaped ring 310 that defines the outer edge of the analog meter 300 and lacks the display surface 210 side. The analog meter 500 defines the outer edge of the analog meter 500 and the display surface 210 side is absent. A C-shaped ring 510 having a circular arc shape is provided. The C-shaped ring 310 and the C-shaped ring 510 have the same size and shape, and are arranged at an equal distance in the horizontal direction from the center of the ring member 610. The C-shaped ring 310 is disposed such that the upper end 311 and the lower end 312 face the ring member 610 side, and the C-shaped ring 510 is also disposed such that the upper end 511 and the lower end 512 face the ring member 610 side. Thereby, the analog meter 300 and the analog meter 500 are arranged symmetrically with respect to the ring member 610.

  Further, the C-shaped ring 310 is arranged such that the interpolation line L310 when the C-shaped ring 310 is circularly interpolated overlaps with the region on the left edge H2 side of the display surface 210. The interpolation line L510 when the ring 510 is circularly interpolated is arranged so as to overlap with the region on the right edge H4 side of the display surface 210. Therefore, the C-shaped rings 310 and 510 can be disposed closer to the display surface 210 than in the case where the C-shaped rings 310 and 510 are configured in a circular shape. Therefore, the analog meters 300 and 500 can be arranged without increasing the width in the left-right direction of the display board region 410.

  In the example of FIG. 3, the C-shaped ring 310 has the upper end 311 disposed in the display surface 210, the lower end 312 is in contact with the lower edge H <b> 1, and the C-shaped ring 510 has the upper end 511 disposed in the display surface 210. The lower end 312 is in contact with the lower edge H1. However, this is only an example, and the C-shaped ring 310 may be arranged such that the upper end 311 is in contact with or in front of the left edge H2, and the lower end 312 is arranged in the display surface 210. Further, the C-shaped ring 510 may be arranged such that the upper end 511 is in contact with or in front of the right edge H4 and the lower end 512 is arranged in the display surface 210.

  In the analog meter 300, an indicator portion 313 is disposed along the inner periphery of the C-shaped ring 310. The indicator unit 313 includes a plurality of scale lines arranged radially along the inner periphery of the C-shaped ring 310. In FIG. 3, since the tachometer indicating the engine speed is used as the analog meter 300, the index unit 313 has 10 scale lines indicating the engine speed from 0000 rpm to 9000 rpm in increments of 1000 rpm. The rings 310 are arranged at almost equal intervals over almost the entire inner periphery of the ring 310. In the example of FIG. 3, the minimum scale line indicating the minimum value of the rotational speed is disposed on the lower end 312 side, and the maximum scale line indicating the maximum value of the rotational speed is disposed on the upper end 311 side.

  The indicator needle 320 is formed of a needle-like member that has the center of the analog meter 300 as a fulcrum O3 and extends linearly in the radial direction of the C-shaped ring 310. The indicator needle 320 is rotated within a range from a scale line having a numerical value “0” to a scale line having a numerical value “9”. In the analog meter 300, when the lowermost part 314 is set to 0 degree and the angle is defined in the clockwise direction, the indicating needle 320 has a movable range from about −30 degrees to about 210 degrees. Note that the angle range of the indicator needle 320 is not limited to these values.

  The analog meter 500 is composed of two pointer-type meters arranged above and below sharing the C-shaped ring 510. The two pointer-type meters are both composed of a mechanical meter, one pointer-type meter corresponds to an example of a second pointer-type meter, and the other pointer-type meter corresponds to an example of a third pointer-type meter. In the example of FIG. 3, a water thermometer is adopted for the upper pointer-type meter, and a fuel gauge is adopted for the lower pointer-type meter. However, this is an example, and a water temperature gauge may be adopted as the lower pointer-type meter, and a fuel gauge may be adopted as the upper pointer-type meter.

  In the analog meter 500, a fuel gauge indicator 513 a and a water temperature indicator 513 b are arranged along the inner periphery of the C-shaped ring 510. The indicator portion 513a includes a plurality of scale lines arranged radially at equal intervals along the inner periphery of the lower half of the C-shaped ring 510. The indicator portion 513b includes a plurality of scale lines arranged at equal intervals along the inner circumference of the upper half of the C-shaped ring 510. The indicator portion 513b has a scale line indicating the lowest temperature disposed slightly above the middle of the C-shaped ring 510 in the vertical direction, and a scale line indicating the highest temperature is disposed on the upper end 511 side. The indicator portion 513a has a scale line indicating that the fuel is full at a position slightly below the middle of the C-shaped ring 510 in the vertical direction, and a scale line indicating that the fuel is empty has a lower end 512. Arranged on the side.

  The indicator needle 520 is formed of a needle-like member that extends linearly in the radial direction of the C-shaped ring 510 with the fulcrum O52 being slightly below the center of the analog meter 500. The indicator needle 520 is rotated within a range of a scale line indicating that the fuel is full from a scale line indicating that the fuel is empty.

  The indicator needle 530 is formed of a needle-like member that extends linearly in the radial direction of the C-shaped ring 510 with the fulcrum O53 being slightly above the center of the analog meter 300. The indicator needle 530 is rotated within a range from the scale line indicating the minimum temperature to the scale line indicating the maximum temperature.

  The fulcrum O53 and the fulcrum O52 are arranged side by side in the vertical direction. Further, when the lowermost part 514 of the analog meter 500 is set to 0 degree and the angle is defined in the counterclockwise direction, the indicating needle 530 sets the range from about 90 degrees to about 195 degrees of the analog meter 500 as a movable range, The needle 520 has a range of about −30 degrees to about 90 degrees of the analog meter 500 as a movable range. Therefore, in the analog meter 500, a fan-shaped range from about 195 degrees to about 330 degrees becomes the blank area 500A. Note that the blank area 500A is not limited to the range defined by these angles, and if the movable range of the indicating needles 520 and 530 is defined by different angles, the margin area 500A varies depending on the movable range.

  The ring body 600 has a larger diameter than the C-shaped rings 310 and 510, and the lowermost part 610a is located below the lower edge H1 of the display surface 210. Therefore, a sufficient area of ring body 600 can be secured, and the visibility of meter image SCI displayed inside ring body 600 can be improved.

  Furthermore, the lowermost parts 314 and 514 of the C-shaped rings 310 and 510 are located at the same height as the lowermost part 610a of the ring body 600 located below the lower edge H1. Thereby, the lower ends of the analog meters 300 and 500 and the ring body 600 are aligned, and the aesthetics of the entire display device 100 can be improved.

  In the analog meter 300, a first indicator group G1 including a plurality of indicators IN1 disposed so as to surround the fulcrum O3 of the indicator needle 320 is disposed. Specifically, the indicator IN1 is arranged clockwise around the fulcrum O3 in the region between the indicator portion 313 and the fulcrum O3 within the movable range of the indicator needle 320 and outside the display surface 210. The indicator IN1 is a lighting indicator. For this reason, the first indicator group G1 can include an indicator that is required to display with a lighting-type indicator instead of a graphic display according to regulations. Note that the lighting-type indicator refers to a physical indicator that is turned on one by one using a light emitting element.
