Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a display device for a vehicle, and more particularly, to a display device having a strong evoking power for a driver.

[0002]

[Prior Art]

 A display device that irradiates a display light from a display device to a reflecting member such as a windshield to form a display image corresponding to the display light as a virtual image in the distance in the field of view in front of the driver is, for example, Japanese Utility Model Laid-Open No. 3-34938. It is disclosed in the official gazette, and in addition to digitally displaying the running speed, time, etc., various vehicle information is also displayed in a pattern according to the item, for example, Japanese Utility Model Publication No. 2-103834 (see FIG. 3). ), Which is not directly related to the present invention, but with respect to the design, see Japanese Utility Model Laid-Open No. 3-52787.

[0003]

[Problems to be solved by the device]

 In such a display device, a fluorescent display tube, a liquid crystal display device with a backlight, an electroluminescent device, or the like is generally used as a display, but in all of them, the irradiation surface of the display light beam is flat, and moreover, pattern display is performed. Since the displayed image is also a two-dimensional image, the displayed image does not have a three-dimensional effect and tends to lack the attractiveness of design.

[0004]

[Means for Solving the Problems]

 The present invention has been conceived in view of such a conventional problem, and a display device having a display device in which a plurality of light emitting bodies that irradiate a display light beam individually or continuously is arranged in parallel is provided in a vehicle. The light emitting body is arranged on the dashboard so that the irradiation surface of the display light in the display has a stepwise difference with respect to the upper surface of the dashboard, and receives the display light from the display device. A reflecting member for forming a display image according to the displayed light rays is provided in the front field of view of the driver.

[0005]

[Action]

 Since the irradiation surface of the display light of the display device has a stepwise difference, the formed display image looks slanted and can give a stereoscopic effect.

[0006]

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings.

Reference numeral 1 is a display device provided on a dashboard 3 of a vehicle 2 and has a display device 4 in which five light emitting diodes (LEDs) 4a to 4e, which are a plurality of light emitting bodies, are arranged in parallel. There is. The LEDs 4a to 4e of the display device 4 are individually controlled by a drive circuit (not shown) and irradiate the display light beams La to Le individually or continuously. With respect to the irradiation surfaces of La to Le, the LEDs 4a to 4e are arranged with a difference such that the LED 4a is located at the top of the dashboard 3 and gradually descends stepwise with respect to the top surface of the dashboard 3. There is.

Reference numeral 5 denotes a windshield of the vehicle 2, and a display light L (at least one of La to Le) emitted from the display 4 is driven in front of the driver 6 on the inner surface of the windshield 5. A semi-transparent reflecting member 7 for reflecting the light to the driver 6 side is provided, and the driver 6 can display a display image 8 corresponding to the display light ray L 2 formed in the visual field in front of the driver 6 within the range of the reflecting member 7. Can be seen overlaid on landscape 9.

In the above-described embodiment, since the surfaces of the LEDs 4a to 4e forming the display 4 have stepwise differences, the display rays La to Le emitted from the LEDs 4a to 4e are reflected by the reflecting member. By being reflected to the driver 6 side by 5, the respective display images 8a to 8e imaged in front of the driver 6 are imaged at positions corresponding to the optical path lengths of the display light beams La to Le, Therefore, the display image 8a is closest to the driver 6, and the display image 8e appears to be positioned farthest in a stepwise manner. As described above, since the irradiation surfaces of the display light beam L of the display device 4 have a difference, it becomes possible to give a stereoscopic effect to the display image 8.

As means for further enhancing the stereoscopic effect, as shown in FIG. 2, the shapes of the LEDs 4a to 4e are set so that the display image 8a seen in the foreground is large (wide) and sequentially small (narrow). It is effective to increase the perspective.

Similarly, the display images 8a and 8b seen in the foreground are reddish which are sensuously forward colors, the display images 8c and 8d at the center are orange or yellowish which are an intermediate color, and the display image seen at the innermost side. It is also effective to set the emission colors of the LEDs 4a to 4e so that 8e becomes a receding blue or greenish color. As an application example of this, the LEDs 4a to 4e can be set so that all the emission colors are different.

[Effect of the device]

 According to the present invention, a display device having a display device in which a plurality of light-emitting bodies that individually or continuously emit display light beams is arranged in parallel is provided on a dashboard of a vehicle, and the irradiation surface of the display light beam on the display device is the dashboard. The light emitters are arranged so as to have a stepwise difference with respect to the upper surface of the board, and a display image corresponding to the display light beam is received in the front visual field of the driver by receiving the display light beam from the display device. A reflective member for forming an image is provided. Due to the difference in the irradiation surface of the display light rays of the display, the formed display image can be seen as tilted to give a three-dimensional effect, which is unprecedented. The design can be displayed. In particular, it is possible to perform the display so that the display image approaches the driver as compared to the conventional one that displays a pattern which is a planar image, and it is possible to perform a display with a strong evoking power to the driver. This is effective for displaying to the driver the caution information of the vehicle during traveling such as an over-speed warning, an inter-vehicle distance decrease warning, or an exhaust temperature rise warning.
