Has been proposed (see Patent Document 1).

In this conventional display device, a display design related to an image displayed on the liquid crystal panel is provided on the decorative ring.
JP 2006-201038 A

  In the above-described conventional display device, the decoration ring is transmitted and illuminated by the light from the liquid crystal panel, but it does not show the image formed on the liquid crystal panel through the decoration ring, so that the appearance of the image is not interesting. was there.

  Further, if only the image and light from the image are passed through the decorative ring, the appearance of the display device may be flat and have a monotonous appearance with little change.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a display device having a novel appearance by devising a configuration of the display device.

  In order to achieve the above object, the present invention employs the following technical means.

According to the first to sixth aspects of the present invention, there is provided a display for forming and displaying various information as an image on a screen, and a translucent material disposed on the display on the front side of the display. A display device that comprises a decorative member, and that visually displays a display design of a part of the image through the decorative member,
The decorative member is formed on the front side of the decorative member on the viewing side, and includes a reflective portion that reflects display light from the display design incident on the decorative member, and the reflective portion forms an image in the decorative member by the reflected display light. The reflected virtual image is configured to be viewed from the viewing side through the reflecting portion as a display design.

  In such an invention, the display design of a part of the image visually recognized through the decorative member is visually recognized in contrast to the image part displayed on the front surface of the display device other than the part of the image. Is provided with a reflection part on the front side of the viewing side, and reflects the display light from the display design incident on the decoration member at the reflection part, and forms an image in the decoration member by the reflected display light. Due to the scattered light of the virtual image, the display design is visually recognized from the viewing side through the reflecting portion.

  According to this, for the viewer who sees the display device, a part of the display design of the image visually recognized as a reflected virtual image through the reflective portion of the decorative member is displayed on the front surface of the display other than the reflected virtual image and the display design. The parallax with the displayed image part can be visually recognized with a stereoscopic effect.

  Therefore, when the display design of a part of the image viewed through the decorative member is viewed in contrast to the image part displayed on the front face of the display other than the part of the image, the parallax allows the viewer to Since it can be visually recognized, a display device with a novel appearance can be provided.

The decorative member is formed in an annular shape so as to be in contact with the outer peripheral edge of the image, as in the invention described in claims 2 to 3.
The reflecting portion includes a first reflecting surface that reflects display light from the display design incident on the decorative member, and a second reflecting surface that reflects and scatters the reflected light from the first reflecting surface,
The first reflecting surface is formed by inclining the viewing side front surface of the decorative member to the screen of the display, and the second reflecting surface is an inner peripheral surface or an outer peripheral surface of the decorative member formed in an annular shape. It is characterized by having a translucent layer.

  According to this, since the reflecting portion has the first reflecting surface formed by inclining the viewing-side front surface of the decorative member to the screen of the display device, the first reflecting surface is used to decorate the decorative member from the display direction rear side. It is possible to reliably reflect the display light that is incident on the member and proceeds to the front side in the display direction, that is, the front side on the viewing side. In addition, since the reflecting portion has the second reflecting surface that is an inner peripheral surface or outer peripheral surface of the decorative member formed in an annular shape and has a light-impermeable layer, the decorative member is formed on the first reflecting surface. The display light reflected inside can be reflected and scattered.

  Thus, design display light reflected by the first reflecting surface can be imaged on the second reflecting surface, and a viewer looking through the first reflecting surface can be connected to the second reflecting surface. The scattered light of the display light of the displayed design display can be visually recognized as a reflected virtual image.

  According to a third aspect of the present invention, in the first reflecting surface, the optical distance between the screen and the first reflecting surface is enlarged or reduced in the extending direction in which the outer peripheral edge of the image extends. It is preferable that they are arranged as described above.

In such an invention, the display design on the outer peripheral side of the image viewed by the viewer through the first reflecting surface of the decorative member is based on the reflected virtual image of the display design on the basis of the inner peripheral side of the image viewed by the viewer on the display screen. Will be displayed in three dimensions due to the parallax,
Since the first reflective surface is arranged so that the optical distance between the screen and the first reflective surface expands or contracts in the extending direction in which the outer peripheral edge of the image extends, the extension of the outer peripheral edge of the image. It is possible to cause a parallax change in which the parallax with the reflected virtual image of the display design is enlarged or reduced with reference to the inner peripheral side of the image in the current direction.

  Thereby, the parallax between the reflected virtual image of the display design seen through the decorative member and the image portion seen on the screen of the display other than the display design is emphasized to the viewer by the parallax change occurring in the extending direction of the outer peripheral edge of the image. You can show it. From the above, it is possible to further improve the novel appearance and allow the viewer to visually recognize it.

  The decorative member is formed in a shape related to the shape of the image as in the inventions according to claims 4 to 5, and the image on the display is a pointer instrument that indicates a physical quantity by a rotation angle position of the pointer. The display design is a scale of a pointer instrument.

  According to this, when the viewer looks at the scale indicated by the pointer, the parallax with the reflected virtual image of the scale that can be seen through the decorative member is based on the pointer that can be seen on the screen of the display unit, and the display is flat and monotonous. Therefore, it is three-dimensional, interesting and easy to read. Therefore, the texture of the display device applied to the vehicle instrument can be improved.

  Further, the scale is preferably displayed in a counterclockwise region from the vicinity of the rotation angle position of the pointer as in the invention described in claim 5.

In such an invention, the image of the pointer instrument is formed, for example, information related to vehicle travel,
Since the area where the scale is displayed is changed in conjunction with the rotation of the pointer, the change in the information related to the vehicle traveling indicated by the rotating pointer is changed in the area where the pointer is rotated and the scale is displayed. It is possible to emphasize and recognize the viewer by both of the fluctuation.

  In particular, the display device preferably includes a liquid crystal panel having a pixel region for displaying an image and a light source for irradiating the liquid crystal panel by light emission.

  According to this, since the display has a liquid crystal panel having a pixel region for displaying an image and a light source for illuminating the liquid crystal panel by light emission, the degree of freedom in selecting information display displayed on the screen is high. Therefore, a novel display image and appearance can be given to the viewer.

  Next, the transparent ring 5 which is a feature of the present invention will be described with reference to FIGS. The transparent ring 5 is a light guide that is disposed so as to be in contact with the outer peripheral edge of the meter image 21 and repeatedly reflects and emits light when light enters the inside.

  In addition, the transparent ring 5 includes an annular surface 52 arranged on the scale 21b corresponding to the outer peripheral image portion in the meter image 21, and an image 21a of the first display design corresponding to the inner peripheral image portion. An opening window 51 that exposes 21c and 21d to the inside and a viewing-side front surface 53 that is disposed on the front side in the display direction of the transparent ring 5 are provided.

  The annular surface 52 is an incident surface formed so that display light from the scale 21 b or the like on the screen 11 enters, and is formed in a planar shape along the meter image 21 on the screen 11.

  The viewing-side front surface 53 is a reflective surface (hereinafter referred to as a first reflective surface) that reflects the display light that is incident on the annular surface 52 and travels forward in the display direction within the transparent ring 5, as shown in FIGS. 3 and 4. In addition, it is inclined with respect to the screen 11 at a predetermined angle (approximately 45 ° in the present embodiment).

  The inner peripheral surface 54 of the annular transparent ring 5 is a light-impermeable layer 55 such as a light-impermeable resin layer or a light-impermeable colored layer that has been subjected to a light-impermeable coloring process by painting. The light traveling toward the inner peripheral surface 54 is reflected by the opaque layer 55. In this embodiment, the inner peripheral surface 54 of the transparent ring 5 forms a second reflecting surface that reflects and scatters the display light reflected by the viewing-side front surface 53.

  As shown in FIG. 4, such an inner peripheral surface 54 has its display light reflected on the viewing-side front surface 53, and does not transmit reflected light traveling to the inner peripheral surface 54 to the outside of the transparent ring 5. A reflected virtual image R of the scale 52 by the reflected light is formed on the inner peripheral surface 54 by being reflected and scattered by the opaque layer 55.

  Thereby, when the driver looks at the meter image 21, the scale 52 is visually recognized as a reflected virtual image R through the viewing side front surface 53 of the transparent ring 5, and the inner peripheral side image portions 21a, 21c, 21d such as the pointer 21d are displayed on the screen. 11 is visually recognized as an image formed as it is. In other words, when the driver compares the scale 12b with the other inner peripheral image portions 21a, 21c, 21d in the meter image 21, the scale is based on the inner peripheral image portions 21a, 21c, 21d. The parallax by the reflected virtual image R of 21b can give the driver a three-dimensional effect and make it visible.

  Further, the viewing-side front surface 53 is not merely inclined with respect to the screen 11, but the extending direction of the scale 21b (the circumference of the scale 21b extending in an annular shape in FIG. 2). The optical distance between the viewing-side front surface 53 and the screen 11 is increased or reduced toward the direction). Specifically, the viewing-side front surface 53 is formed so that the optical distance between the viewing-side front surface 53 and the screen 11 increases clockwise in the extending direction of the scale 21b. In other words, the viewing-side front surface 53 is inclined spirally with respect to the screen 11.

  From the above, the driver sees the scale 21b as the reflected virtual image R through the viewing-side front surface 53 of the transparent ring 5 in contrast to the inner peripheral image portions 21a, 21c, and 21d seen on the screen 11. Since the optical distance between the viewing-side front surface 53 and the screen 11 is increased in the clockwise extending direction in which 21b extends, the scale 21b of the reflected virtual image R and the inner peripheral image portions 21a, 21c, and 21d. The parallax change in which the parallax with the angle increases in the clockwise extending direction can be generated.

  As a result, the parallax between the reflected virtual image R of the scale 21b seen by the driver and the inner peripheral image portions 21a, 21c, and 21d seen on the screen 11 is enlarged in the clockwise extending direction to change the parallax. By doing so, the driver can be emphasized.

  In the viewing side front surface 53, the region where the optical distance between the viewing side front surface 53 and the screen 11 is enlarged or reduced is not limited to that formed in a part of the viewing side front surface 53 as shown in FIG. It may be formed on the entire front surface 53.

  In an example of a part of the viewing side front surface 53 shown in FIG. 2, the viewing side front surface 53 includes a first region surface 53 a that occupies a region exceeding the extension range of the scale 21 b formed on the viewing side front surface 53, and a scale. 21b includes a second region surface 53b occupied by a region that is not continuously formed. In the first area surface 53a, the optical distance between the surface 53a and the screen 11 is increased in the clockwise extending direction, and in the second area surface 53b, the surface 53b and the screen 11 are enlarged. And the optical distance between the two is substantially constant.

  Further, the outer peripheral surface 56 of the transparent ring 5 is formed of a light-transmitting resin 57 or a light-transmitting member 57 having a light-transmitting colored layer subjected to a light-transmitting coloring process by painting. . Thereby, since the light from the screen 11 incident from the annular surface 52 is emitted only from the viewing-side front surface 53, the viewing-side front surface 53 can be emphasized and illuminated as the illumination unit 21e of the meter image 21. it can.

  Here, the viewing side front surface 53 corresponds to the first reflecting surface described in the claims, and the inner peripheral surface 54 corresponds to the second reflecting surface described in the claims. Further, the viewing side front surface 53 and the inner peripheral surface 54 correspond to the reflecting portion described in the claims. The liquid crystal panel 10 and the backlight 30 constitute the liquid crystal display 2 and correspond to the display described in the claims.

In the present embodiment described above, the transparent ring 5 made of a translucent material is disposed on the liquid crystal panel 10 on the screen 11 side of the liquid crystal panel 10, and the scale 21 b that is a part of the meter image 21 passes through the transparent ring 5. In the display device 100 visually recognized from the driver side,
The transparent ring 5 is formed on the viewing-side front surface 52 of the transparent ring 5 and includes reflecting portions 53 and 54 that reflect the display light from the scale 21b incident on the transparent ring 5. The reflected virtual image R formed in the transparent ring 5 by the reflected display light is configured to be visually recognized by the driver through the reflecting portions 53 and 54 as the scale 21b.

  According to such a configuration, the transparent ring 5 is provided with the reflecting portions 53 and 54 on the viewing-side front surface 53 side, and scattering of the reflected virtual image R formed in the transparent ring 5 at the reflecting portions 53 and 54. The scale 21b, which is the first display design, is visually recognized from the viewing side through the reflecting portions 53 and 54 by light.

  According to this, the scale 21b visually recognized as the reflected virtual image R for the driver viewing the display device 100 is displayed on the reflected virtual image R and the screen 11 which is the second display design other than the scale 21b. The parallax with the peripheral image portions 21a, 21c, and 21d can be visually recognized with a stereoscopic effect.

  Therefore, when the scale 21b visually recognized through the transparent ring 5 is visually recognized in comparison with the inner peripheral image portions 21a, 21c, and 21d displayed on the screen 11, the stereoscopic effect is given to the driver by the parallax. Therefore, the display device 100 with a novel appearance can be provided.

  In the present embodiment described above, the reflecting portions 53 and 54 have a first reflecting surface and a second reflecting surface, and the first reflecting surface is the viewing side front surface 53, and the viewing side front surface. 53 is formed to be inclined to the screen 11. As the first reflecting surface, the viewing-side front surface 53 reliably reflects the display light incident on the transparent ring 5 from the back side in the display direction of the transparent ring 5 and traveling to the front side in the display direction, that is, the viewing-side front surface 53. be able to. In addition, the second reflecting surface is the inner peripheral surface 54 of the annular ring 5 formed in an annular shape, and the inner peripheral surface 54 includes the light-impermeable layer 55. The display light reflected inside can be reflected and scattered.

  As described above, the display light of the scale 21 b reflected by the viewing-side front surface 53 can be imaged on the inner circumferential surface 54 of the transparent ring 5, and the inner circumferential surface for the driver looking through the viewing-side front surface 53. The scattered light of the scale 21b formed on 54 can be visually recognized as a reflected virtual image.

  In the present embodiment described above, the viewing-side front surface 53 that is the first reflecting surface increases the optical distance between the viewing-side front surface 53 and the screen 11 in the clockwise extending direction of the scale 21b. Is formed.

  According to this, the driver sees the scale 21b as a reflected virtual image R through the viewing-side front surface 53 in contrast to the inner peripheral image portions 21a, 21c, and 21d seen on the screen 11. Since the optical distance between the viewing-side front surface 53 and the screen 11 is increased in the clockwise extending direction in which the scale 21b extends, the scale 21b of the reflected virtual image R and the inner peripheral image portions 21a, 21c, It is possible to cause a parallax change in which the parallax with 21d expands in the clockwise extending direction.

  As a result, the parallax between the reflected virtual image R of the scale 21b seen by the driver and the inner peripheral image portions 21a, 21c, and 21d seen on the screen 11 is enlarged in the clockwise extending direction to change the parallax. By doing so, the driver can be emphasized. As described above, the novel appearance can be further improved and the driver can visually recognize the appearance.

  In the present embodiment described above, the transparent ring 5 is formed in an annular shape, that is, in a shape related to the shape of the meter image 21. The meter image 21 has a first display design and a second display design, and is a pointer instrument that indicates a physical quantity by a rotation angle position of the pointer 21 d related to the first display design, and is visually recognized through the transparent ring 5. The second design is the scale 21b of the pointer instrument.

  According to this, when the driver looks at the scale 21b indicated by the pointer 21d, the parallax with the reflected virtual image R of the scale 21b seen through the transparent ring 5 is based on the pointer 21d seen on the screen 11 of the liquid crystal panel 10. Therefore, it is three-dimensional, interesting and easy to read without being flat and monotonous. Therefore, it is possible to improve the texture of the display device 100 applied to the vehicle instrument as in this embodiment.

  Further, in the present embodiment described above, the liquid crystal panel 10 having the pixel region 12 that displays an image such as the meter image 21 and the light source such as the backlight 30 that irradiates the liquid crystal panel 10 by light emission are provided.

  According to this, since the display device includes the liquid crystal panel 10 having the pixel region 12 for displaying an image and the light source that irradiates the liquid crystal panel 10 by light emission, selection of information display displayed on the screen 11 is performed. Since the degree of freedom is high, for example, the liquid crystal panel is driven and controlled so that the area where the scale which is the first display design is displayed is changed in conjunction with the rotation of the pointer related to the second display design. It is possible to give the driver a unique display image and appearance.

Displayed in the area.

  According to this, since the area in which the scale 21b is displayed is changed in conjunction with the rotation of the pointer 21d, the change in the vehicle speed information related to the vehicle traveling indicated by the rotating pointer 21d is changed. It can be emphasized and recognized by the driver by both the movement and the change of the area where the scale 21d is displayed.
