Can be transparently displayed.

  The light source unit 40 is formed by arranging a plurality of light emitting elements 41 on a light source circuit board 42 in a straight line with an arrangement pitch PT0. Each light emitting element 41 employs a light emitting diode as a point light source, and each light emitting element 41 emits light when connected to a power source. In particular, in the present embodiment, each light emitting element 41 is a multicolor light emitting diode, but may be a single color light emitting diode. In any case, each light emitting element 41 in the lit state is preferably controlled so as to emit light with substantially the same color and substantially the same luminance.

  Such a light source unit 40 is arranged to face the outer edge portion 32a on the upper side of the vehicle among the outer edge portions 32 of the translucent display panel 30. The outer edge portion 32 a forms a planar facing surface 30 a that faces the light emitting element 41 of the light source portion 40. The light source light emitted from each light emitting element 41 enters the inside of the translucent display panel 30 through the opposing surface 30a at the outer edge portion 32a. Thus, the light source unit 40 can provide light source light.

  The light source light introduced into the interior of the translucent display panel 30 travels in the interior with the direction from the vehicle upper side to the vehicle lower side as the main traveling direction.

  The translucent display plate 30 has a reflective display portion 33. As shown in FIGS. 3 to 5, the reflective display unit 33 is an element formed to be recessed from the back plate surface 31 b, and includes a plurality of reflective elements 35 having a fine size with a recessed depth of about 5 to 20 μm. ing. The reflective display unit 33 forms a symbol 34 that can be viewed macroscopically by appropriately arranging a plurality of reflective elements 35. In particular, in the present embodiment, the design 34 is formed by two-dimensionally arranging the plurality of reflecting elements 35 along the back plate surface 31b. Each reflective element 35 has a reflective surface that reflects light source light introduced into the translucent display panel 30 to the viewer side, so that the design 34 is brilliantly displayed.

  Specifically, in the present embodiment, as the design 34, a frame design 34 a formed in an annular frame shape so as to border the periphery of the pointer display unit 22 over the entire circumference, and a display surface 25 b of the image display unit 25. A frame pattern 34b formed in a rectangular ring shape is provided so as to border the entire circumference.

  The plurality of reflective elements 35 include a composite reflective element 36. In particular, in the present embodiment, all the reflective elements 35 constituting the reflective display unit 33 are composite reflective elements 36.

  Each composite reflective element 36 is formed to be recessed in a triangular pyramid shape from the back plate surface 31b to the front plate surface 31a side. In particular, as shown in FIG. 3, each composite reflective element 36 has an isosceles triangular shape on a plan view along the thickness direction TD perpendicular to the back plate surface 31b. Each composite reflective element 36 has a composite reflective surface 37 composed of two inclined surfaces 37 a and 37 b and an element back surface 38.

  The two inclined surfaces 37a and 37b are respectively arranged at positions corresponding to the equilateral sides in the isosceles triangular shape on the plan view. The two inclined surfaces 37a and 37b are two surfaces facing the outer edge portion 32a on the vehicle upper side where the light source light is introduced, among the surfaces formed by the triangular pyramid-shaped composite reflecting element 36, and the outer contours are formed in a triangular planar shape. Each is formed.

  Each composite reflective element 36 includes a straight connection side 36b that connects two inclined surfaces 37a and 37b along a cross section that bisects the apex angle (or base) of the isosceles triangle on the plan view. Have. The connection side 36b is inclined so as to be further away from the outer edge portion 32a on the vehicle upper side where the light source light is introduced as it goes from the back plate surface 31b side to the front plate surface 31a side, and particularly shown in FIG. Thus, for example, an inclination angle of 45 degrees is formed with respect to the thickness direction TD. Similarly to the connection side 36b, the inclined surfaces 37a and 37b are further separated from the outer edge portion 32a on the upper side of the vehicle where the light source light is introduced from the back plate surface 31b side to the front plate surface 31a side. Inclined. Each inclined surface 37a, 37b also forms an inclination angle of, for example, 45 degrees with respect to the plate thickness direction TD on a cross section parallel to the cross section that bisects the apex angle.

  Further, the two inclined surfaces 37a and 37b are set so that their directions are different from each other on the basis of the outer edge portion. Specifically, the two inclined surfaces 37a and 37b are directed obliquely to each other in a shape along the isosceles triangle-like equilateral slope on the plan view. The inclined surface 37a on the left side of the vehicle is slightly facing the left side of the vehicle, and the inclined surface 37b on the right side of the vehicle is slightly facing the right side of the vehicle. Specifically, in the present embodiment, the triangular pyramid-shaped composite reflective element 36 includes a concave bottom portion 36a having the deepest dent depth, and particularly on a vertical section perpendicular to the section that bisects the apex angle. As shown in FIG. 5, the two inclined surfaces 37a and 37b are inclined in opposite directions to each other at an inclination angle of, for example, 10 degrees with respect to the back plate surface 31b.

  The element back surface 38 is disposed at a position corresponding to the base in the isosceles triangle shape on the plan view, and is formed facing the side opposite to the outer edge portion 32a on the vehicle upper side where the light source light is introduced. The element back surface 38 is formed in a planar shape having a triangular outer contour. The element back surface 38 is inclined so as to approach the outer edge portion 32a on the vehicle upper side where the light source light is introduced as it goes from the back plate surface 31b side to the front plate surface 31a side. It has an inclination angle of degrees.

  As shown in FIG. 3, when the light source light is incident on each composite reflective element 36 from the upper side of the vehicle toward the lower side of the vehicle, the composite reflective surface composed of the two inclined surfaces 37a and 37b that are inclined as described above. 37, the light source light is reflected to the viewing side. In this way, each reflective element 35 is shined and visually recognized by the occupant located on the viewing side.

  In the present embodiment, the composite reflection elements 36 are spaced apart from each other by arrangement pitches PT1 and PT2 set in the arrangement directions D1 and D2, respectively, via the flat portions 39 formed flat on the back plate surface 31b. One by one is arranged in isolation. The arrangement direction D1 extends from the vehicle upper side to the vehicle lower side, which is the main traveling direction of the light source light, and the arrangement direction D2 is a direction substantially perpendicular to the arrangement direction D1.

  The plurality of composite reflective elements 36 are arranged in a so-called zigzag pattern in which the positions of the concave bottom portions 36a are shifted by half the array pitches PT1 and PT2 for each row. Here, the arrangement pitches PT1 and PT2 of the composite reflection element 36 are set to an extremely small value with respect to the arrangement pitch PT0 of the light emitting elements 41 of the light source unit 40.

  The reflection display unit 33 in which the plurality of composite reflection elements 36 are arranged has a surface area where the composite reflection elements 36 in the design 34 are arranged by reflecting the light source light from each composite reflection surface 37 as described above. It can be displayed in a light source shape.

  In particular, in the present embodiment, uneven illumination is generated in the light source unit 40 by arranging the light emitting elements 41 in the form of point light sources. The planar opposing surface 30a introduces the light source light into the translucent display panel 30 without changing the illumination unevenness of the light source light as much as possible at the outer edge portion 32a. When each composite reflection element 36 reflects the light source light from such a light source section 40, the reflection display section 33 arranges a light source image by a plurality of point light source-like light emitting elements 41, and the composite reflection elements 36 in the pattern 34 are arranged. The image is displayed in a printed area.

  Such copying of the light source image will be described in more detail with reference to FIGS. In the present embodiment, since the composite reflective element 36 reflects the light source light by the composite reflective surface 37 formed by two inclined surfaces 37a and 37b, the angle at which the viewer visually recognizes the design 34 of the reflective display unit 33. Changes the appearance of the light source image.

  Specifically, as shown in FIG. 6 or 9, when the viewer visually recognizes the pattern 34 so that the viewer looks down slightly from the upper side of the vehicle, a plurality of light source images extending linearly correspond to the arrangement pitch PT0 of the light emitting elements 41. Reflected at intervals, striped luminance unevenness is generated in the pattern 34 of the reflective display unit 33.

  As shown in FIG. 7 or 10, when the viewer visually recognizes the pattern 34 from the front along the plate thickness direction PT, the light source image extending in a straight line is reflected twice as compared with the above case, and the reflection display unit The 33 patterns 34 are caused to have complex striped luminance unevenness.

  As shown in FIG. 8 or 11, when the viewer visually recognizes the pattern 34 so as to look up slightly from the lower side of the vehicle, the number of light source images extending linearly returns to the initial case, and the arrangement pitch PT0 of the light emitting elements 41 is reached. Reflection is performed at an appropriate interval, and striped luminance unevenness is generated in the reflective display unit 33.

  If the viewer is, for example, a driver, the symbol 34 is visually recognized as shining with the movement of the eye position accompanying the driving operation of the vehicle.

  The design 34 of the reflective display unit 33 that shines brightly is displayed together with the display by the main body display unit 20 arranged to face the back plate surface 31b of the translucent display panel 30. Therefore, the main body display unit 20 also functions as a superimposed display unit that performs superimposed display superimposed on the display of the symbol 34 toward the viewer side.

  On the other hand, when the light source unit 40 is turned off and the light source light is not introduced into the translucent display plate 30, the composite reflective elements 36 are formed with a fine size and the flat part 39, so that they are hardly visible. It is like that.

(Function and effect)
The operational effects of the present embodiment described above will be described again below.

  According to the present embodiment, the two inclined surfaces 37a and 37b provided on the composite reflection surface 37 of the composite reflection element 36 are outer edges into which light source light is introduced from the back plate surface 31b side toward the front plate surface 31a side. Although they have a common point of being inclined so as to be separated from the portion 32a, their directions are different from each other. In such reflection of the light source light to the viewing side by the composite reflecting element 36, when the viewer shakes the line of sight, the method of changing the brightness differs between the two inclined surfaces 37a and 37b. The pattern 34 of the reflective display part 33 including it shines and is visually recognized. In this way, the display of the design 34 to which a glittering feeling is imparted is realized by the reflective display section 33, so that it is possible to provide the vehicular display device 100 with improved appearance.

  In addition, according to the present embodiment, the two inclined surfaces 37a and 37b are two surfaces facing the outer edge portion 32a side where the light source light is incident, among the surfaces formed by the triangular pyramid-shaped composite reflective element 36. In this way, it is possible to easily realize a configuration in which the two inclined surfaces 37a and 37b whose directions are different from each other reflect the light source light to the viewing side, and the appearance is improved.

  Further, according to the present embodiment, the image by the light emitting element 41 as a plurality of point light source-like light sources is displayed by being imprinted on the area in the design 34 where the composite reflecting element 36 is arranged. That is, the image by the light emitting element 41 is reflected by the two inclined surfaces 37a and 37b and visually recognized. Here, when the viewer shakes his / her line of sight, the manner in which the luminance of the image is changed by the light source differs between the two inclined surfaces 37a and 37b, so that the glittering feeling of the pattern 34 can be emphasized significantly. Therefore, an extremely novel display that could not exist before is realized, and the appearance is further improved.

  In addition, according to the present embodiment, since the plurality of composite reflective elements 36 are spaced apart via the flat portion 39, the positional relationship and area ratio between the composite reflective element 36 and the flat portion 39 are appropriately set. Thus, the brightness and appearance of the symbol 34 can be adjusted, and the range of expression of the symbol 34 can be expanded. Further, by making the size of the composite reflective element 36 fine and making the area of the flat portion 39 a certain ratio or more, the composite reflective element 36 is almost invisible to the viewer when the light source unit 40 is turned off. be able to. As a result, the appearance is improved.

  Further, according to the present embodiment, the composite reflective elements 36 are arranged in a zigzag pattern with their positions shifted by half the array pitch for each column. In this way, since a relatively gentle impression can be given to the symbol 34, the appearance is improved.

  Moreover, according to this embodiment, the main body display part 20 which functions as a superimposed display part which is arrange | positioned facing the backplate surface 31b and performs the superimposed display superimposed on the reflective display part 33 toward a visual recognition side is further provided. The main body display unit 20 and the reflective display unit 33 in which a glittering feeling is produced are superimposed to realize a display having both a sense of unity and a stereoscopic effect. Therefore, it is possible to provide the vehicular display device 100 that is further improved in appearance.

Also good. The composite reflective element 36 may have an additional reflective surface in addition to the composite reflective surface 37.

  As a fourth modification, the inclination angles of the two inclined surfaces 37a and 37b can be set as appropriate as long as the function of reflecting the light source light to the viewing side is maintained. Further, the inclined surfaces 37a and 37b do not have to be completely flat, and may be formed in a slightly curved surface.
