Japanese Patent Laid-Open No. 2006-114423

  However, in Patent Document 1, first, since the dial and the liquid crystal display panel are arranged in the same plane and side by side, there is no relative depth between them. Secondly, since the distance between the reflective portion of the transparent display panel and the liquid crystal display panel is uniquely determined by the position of the dial, the relative depth between the transparent display panel and the liquid crystal display panel is determined in combination. The grant between is relatively limited.

  As described above, since the depth is connected to the stereoscopic effect of the display, conventionally, the relative stereoscopic effect is poor between the display of the dial and the reflection portion and the display of the liquid crystal display panel. There is a problem that various variable displays unique to the section cannot be effectively connected to a stereoscopic effect.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to improve the relative stereoscopic effect between the display of the dial plate and the reflection portion and the liquid crystal display panel. It is to provide a display device.

Reflecting portions (54a, 54b, 254a, 254b, 354a, 354b, 454, 554) that reflect light from the light source (70, 270, 370, 470, 570) arranged on the viewing side of the dial to the viewing side A light transmissive display board (50, 250, 350, 450, 550) provided with
The area of the dial faced to the image display panel is set to be light transmissive so that the image of the image display panel can pass through the area.

  Since the present invention is provided with such a configuration, the image display panel is not arranged side by side in the same plane with respect to the dial, but is arranged on the back side of the dial. The depth of the image display panel with respect to the dial plate and the light transmissive display plate is increased as compared with the side-by-side state. The image on the image display panel can reach the direction of the light transmissive display plate through the light transmissive region of the dial. As described above, an increase in the depth of the image display panel improves the relative three-dimensional effect in the combination of the display by the reflection part of the dial and the light-transmitting display plate and the display of the image display panel. We can expect special effect.

  Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. In addition, the overlapping description may be abbreviate | omitted by attaching | subjecting the same code | symbol to the corresponding component in each embodiment. When only a part of the configuration is described in each embodiment, the configuration of the other embodiment described above can be applied to the other part of the configuration. In addition, not only combinations of configurations explicitly described in the description of each embodiment, but also the configurations of a plurality of embodiments can be partially combined even if they are not explicitly specified unless there is a problem with the combination. .

(First embodiment)
As shown in FIG. 1, the vehicular display device 100 according to the first embodiment of the present invention is mounted on a vehicle and installed on an instrument panel facing a seat on which an occupant who views the device 100 is seated. The vehicle display device 100 can display vehicle information toward the viewing side where the occupant is located. A vehicle on which the vehicle display device 100 is mounted is, for example, a hybrid vehicle including both an engine and an electric motor as driving means.

  As shown in FIGS. 2 and 3, such a vehicle display device 100 includes a case unit 10, a dial plate 20, a pointer 30, an image display panel 40, an image control unit 82, a light transmissive display plate 50, and a display plate The light source 70 for light and the light source control part 83 are provided. The case portion 10 includes a rear case 12 and a wind plate 14 having light shielding properties, and a light transmitting plate 16 that is disposed on the most visible side in the apparatus 100 and has light transmittance. The translucent plate 16 is formed in a plate shape with a light translucent resin such as a colored acrylic resin. The translucent plate 16 is set to a transmittance of about 30% by smoke-like coloring, but may be set to an arbitrary value of 30% or more.

  The dial plate 20 is arranged on the back side of the translucent plate 16 and the light transmissive display plate 50. The back side is the side opposite to the viewing side. The dial plate 20 is formed in a flat plate shape, for example, by partially printing light semi-transparent or light-shielding on the surface on the viewing side of a base material made of a synthetic resin having optical transparency. In addition, it may replace with printing and the coating may be given.

  Such a dial 20 has the indicator part 22 corresponding to vehicle information on the viewing side. The indicator portion 22 is surrounded by light-shielding printing on the dial plate 20 and is subjected to semi-transparent printing, thereby forming an outline of an indicator such as a character or a scale. The indicator portion 22 of the dial plate 20 only needs to include characters, scales, or marks corresponding to the vehicle information, and even if the name is “dial plate”, the characters need not necessarily be included. .

  The indicator portion 22 is illuminated from the back side by the indicator light emitting element 28 mounted on the main circuit board 80 on the back side of the dial 20.

  In addition, in the indicator portion 22 of the present embodiment, in accordance with a pointer 30 to be described later, characters and scales representing the engine speed in the left region of the dial plate 20, characters and scales representing the remaining fuel amount in the upper right region, right Characters and scales representing the engine cooling water temperature are arranged in the lower region.

  A total of three pointers 30 are provided, one corresponding to the left area of the dial plate 20, one corresponding to the upper right area, and one corresponding to the lower right area. Each pointer 30 integrally includes a connecting portion 32 and an instruction portion 34. The connecting portion 32 is disposed through a through hole formed in the dial plate 20 and is connected to the rotating shaft of the stepping motor 36 held on the main circuit board 80. The instruction unit 34 is disposed between the dial plate 20 and the light-transmitting display plate 50 and has a needle shape. The indication part 34 of each pointer 30 is rotated in accordance with the output of the stepping motor 36, and indicates each indicator part 22 arranged in a partial annular form in the left and right areas of the dial 20, respectively. The vehicle information is displayed.

  In the present embodiment, the pointer 30 corresponding to the left region displays the engine speed as the vehicle information. The pointer 30 corresponding to the upper right area displays the remaining amount of fuel as vehicle information. The pointer 30 corresponding to the lower right region displays the coolant temperature of the engine coolant as vehicle information.

  The image display panel 40 is disposed between the main circuit board 80 and the dial plate 20 so as to face the back side of the dial plate 20. A gap is provided between the dial 20 and the image display panel 40. In the present embodiment, the image display panel 40 is disposed corresponding to the central region of the dial 20. For this reason, the image display panel 40 is arranged so as to be sandwiched between displays by the left and right hands 30.

  The image display panel 40 of the present embodiment employs a liquid crystal panel using thin film transistors, which is an active matrix type liquid crystal panel formed from a plurality of liquid crystal pixels arranged in a two-dimensional direction. The image display panel 40 illuminates and displays an image by emitting display light to the viewing side from a rectangular display surface 40a facing the viewing side by illuminating the backlight 42 from the back side. Yes.

  The image control unit 82 is particularly shown in FIG. 2, but is mounted on, for example, the main circuit board 80, and has at least one processor, a memory, and an input / output interface. The processor can control an image on the image display panel 40 via an input / output interface by executing a computer program stored in a memory, for example.

  Here, in the central region of the dial plate 20 facing the image display panel 40, the light-transmitting base material of the dial plate 20 is exposed because printing is not performed. Accordingly, the central area of the dial 20 is set as a transmissive area 24 having light transparency so that display light of the image on the image display panel 40 can be transmitted. The transmissive region 24 is arranged in a size slightly smaller than the display surface 40a. Such a transmissive region 24 is surrounded by a light-shielding region 26 having a light-shielding property by black printing, so that its outline is formed in a rectangular shape.

  The light transmissive display board 50 is formed in a flat plate shape by using a synthetic resin having light permeability, for example. The light-transmitting display plate 50 is disposed on the viewing side with respect to the dial plate 20 and the pointer 30 and is provided substantially parallel to the dial plate 20. For this reason, the installation direction ED of the light-transmitting display board 50 is along the installation direction of the display surface 20a and the installation direction of the dial plate 20, and the thickness direction TD of the light-transmitting display board 50 is the display direction. Along the direction perpendicular to the surface 20 a and the thickness direction of the dial 20. In addition, the plate | board thickness direction TD of this embodiment substantially corresponds to the perpendicular | vertical direction with respect to the surface with the largest area of the transparent display board 50. FIG. The light-transmitting display board 50 has a substantially rectangular shape so as to cover the entire face of the dial 20 from the viewing side.

  As shown in FIG. 2, the display panel light source 70 includes two light emitting portions 72 a and 72 b that are spaced apart from each other on the left and right. The light emitting portions 72 a and 72 b are arranged along the outer edge portion 52. More specifically, each of the light emitting portions 72 a and 72 b is formed by arranging a plurality of light emitting elements 73 a and 73 b that emit light source light along the outer edge portion 52 of the light transmissive display panel 50. Each light emitting element 73a, 73b is a light emitting diode mounted on the light source circuit board 81, and emits light when connected to a power source. In particular, in the present embodiment, the light emitting elements 73a and 73b are multicolor light emitting diodes. Accordingly, the display panel light source 70 of the present embodiment includes a color light source.

  More specifically, each light emitting element 73 a in the light emitting portion 72 a faces the side surface of the outer edge portion 52 on one lower side of the outer edge portion 52 of the light transmissive display panel 50. Similarly, each light emitting element 73b in the light emitting portion 72b is opposed to the side surface of the outer edge portion 52 on one lower side of the outer edge portion 52 of the light transmissive display panel 50. By emitting light source light toward the side surface where each light emitting element 73a, 73b opposes, the light source light advances from the lower side to the upper side inside the light transmissive display panel 50. The light source light of each of the light emitting elements 73a and 73b incident on the inner side of the light transmissive display board 50 through the outer edge portion 52 illuminates an illumination range in which a part of each of the light source elements 73a and 73b is shifted in the installation direction ED. . The display panel light source 70 is preferably arranged so as not to be seen by the passengers, but is shown by a solid line in part of the front view for the sake of explanation.

  The light source controller 83 is mounted on the main circuit board 80, for example, and has at least one processor, a memory, and an input / output interface. The processor can control the light source 70 for the display board via the input / output interface by executing a computer program stored in a memory, for example. Specifically, the light source control unit 83 can switch on and off the light emitting elements 73a and 73b of the display panel light source 70. Further, the light source control unit 83 can change the light emission color of each light emitting element 73a, 73b to various colors. In particular, in the present embodiment, the light source control unit 83 switches on and off and changes the emission color for each of the light emitting units 72a and 72b.

  As shown in FIGS. 1 to 4, the light transmissive display board 50 has reflection portions 54 a and 54 b in partial areas. In particular, in the present embodiment, two reflecting portions 54a and 54b are arranged corresponding to the left and right light emitting portions 72a and 72b. 1 and 2, the areas displayed by the reflecting portions 54a and 54b are indicated by hatching (the same applies to the corresponding drawings hereinafter).

  More specifically, as shown in FIGS. 4 and 5, each reflecting portion 54 a, 54 b has a plurality of reflecting elements 56 arranged along the side-by-side direction ED of the light transmissive display board 50. Each reflective element 56 is set to a fine size, and is formed in a recessed hole shape that is recessed from the back side of the light-transmitting display panel 50 into the display panel 50. Each reflective element 56 has a reflective surface 57a and an inclined back surface 57b.

  The reflective surface 57a is disposed in the reflective element 56 so as to face the light emitting portion 72a or 72b. The reflection surface 57a is formed in a curved surface shape. The reflective surface 57a is extended in an inclined direction inclined with respect to the thickness direction TD of the light transmissive display panel 50. The inclination direction is preferably set in a range of, for example, 39 to 45 degrees with respect to the plate thickness direction TD.

  The inclined back surface 57b is provided facing away from the reflecting surface 57a, and is thus arranged back to back with the reflecting surface 57a. The inclined back surface 57b is formed in a planar shape inclined by, for example, 25 degrees with respect to the plate thickness direction TD. That is, the inclined back surface 57b is set to have an inclination angle smaller than the inclination of the reflecting surface 57a.

  In each reflection part 54a, 54b, each reflection element 56 is spaced apart from each other through a flat part 58 formed flat along the extending direction ED of the light-transmitting display panel 50. ing. In particular, in the present embodiment, the density of the reflecting elements 56 in the reflecting portions 54a and 54b is substantially the same at each location, and the shape of the reflecting element 56 is also substantially the same at each location.

  When the light source light reaches such a reflection part 54a from the light emission part 72a of the light source 70 for display panel, the light source light is reflected to the viewing side by the reflection surface 57a of each reflection element 56 facing the light emission part 72a. Become. Similarly, when the light source light reaches the reflecting portion 54b from the light emitting portion 72b of the display panel light source 70, the light source light is reflected to the viewing side by the reflecting surface 57a of each reflecting element 56 facing the light emitting portion 72b. Become. Therefore, as shown in FIGS. 1 and 2, when the light emitting unit 72 a corresponding to the one reflecting unit 54 a is turned on, the symbol 60 a configured by the reflecting elements 56 arranged in the reflecting unit 54 a is lit and displayed. . Similarly, when the light emitting unit 72b corresponding to the one reflecting unit 54b is turned on, the symbol 60b configured by the reflecting elements 56 arranged in the reflecting unit 54b is illuminated and displayed.

  The symbols 60a and 60b of the present embodiment are outer peripheral symbols 61a and 61b arranged symmetrically with respect to the left and right regions, respectively. The outer peripheral symbol 61a constituted by the reflecting portion 54a is formed in a line shape so as to border the indicator portion 22 in a region corresponding to the outer peripheral portion of the left indicator portion 22 in the light-transmitting display board 50. For example, it has an arc shape. Both end portions 62a and 63a of the outer peripheral design 61a extend to a region of the light transmissive display panel 50 that faces the image display panel 40. The outer peripheral pattern 61b configured by the reflecting portion 54b is formed in a line shape so as to border the indicator portion 22 in a region corresponding to the outer peripheral portion of the left indicator portion 22 in the light-transmitting display board 50. For example, it has an arc shape. Both end portions 62b and 63b of the outer peripheral design 61b extend to a region facing the image display panel 40 in the light transmissive display panel 50.

  Each of the outer peripheral symbols 61a and 61b can be displayed by changing the color individually by including a color light source as well as switching between display and non-display as the corresponding light emitting units 72a and 72b are turned on and off. It has become. As shown in FIG. 6, the outer peripheral symbols 61 a and 61 b are almost not seen from the viewing side due to the setting of the size and density of the reflecting element 56 when the corresponding light emitting portions 72 a and 72 b are not displayed. Not visible.

  The lighting and extinguishing of the light emitting units 72a and 72b and the color change are controlled in cooperation with an image displayed on the image display panel 40. The display type of the image can be selected and set according to the preference by the occupant, for example, using a changeover switch provided on the vehicle, and is temporarily changed depending on the mode of the vehicle and the situation of the periphery monitoring by the vehicle periphery monitoring device. There are also display types.

  The display type A shown in FIG. 1 is a display type in which the speed of the vehicle as vehicle information is digitally displayed in the image using the character image ILT. When the eco mode is not selected in the vehicle, the outer peripheral symbols 61a and 61b are also displayed in white by the light emitting portions 72a and 72b emitting white light. On the other hand, when the eco mode is selected, the color is changed so that each of the light emitting units 72a and 72b emits green light, for example, and the outer peripheral symbols 61a and 61b are also displayed in green. The eco mode is a mode in which vehicle control is performed to suppress the engine speed to a low level, for example.

  In the display type B shown in FIG. 7, in the image, the speed of the vehicle as the vehicle information is digitally displayed by the character image ILT, and the current value of the electric motor as the other vehicle information is displayed on the scale image ISC by the pointer image IPO. It is a display type that displays analog when instructed. When the eco mode is not selected in the vehicle, the outer peripheral symbols 61a and 61b are also displayed in white by the light emitting portions 72a and 72b emitting white light. On the other hand, when the eco mode is selected, the color is changed so that each of the light emitting units 72a and 72b emits green light, for example, and the outer peripheral symbols 61a and 61b are also displayed in green.

  The display type C shown in FIGS. 8 and 9 is a display type in which the gear position is displayed on the left side of the display surface 40a and the vehicle speed is displayed on the right side as a character image ILT, and various information is displayed in the center of the display surface 40a. .

  In the display type C, when the idle stop mode is not selected in the vehicle, the light emitting portions 72a and 72b emit white light as shown in FIG. Is displayed. At this time, the image display panel 40 further extends the lower ends 62a and 62b of the outer peripheral symbols 61a and 61b, and is an extension provided linearly so as to connect the lower ends 62a and 62b. The image IE1 is displayed. In addition, the image display panel 40 further extends the upper end portions 63a and 63b of the outer peripheral symbols 61a and 61b, and extends the image IE2 provided in a linear shape so as to connect the upper end portions 63a and 63b. Is displayed.

  On the other hand, as shown in FIG. 9, when the idle stop mode is selected in the vehicle, the left light emitting portion 72a is turned off, the left outer peripheral symbol 61a is hidden, and the right light emitting portion 72b is white. By turning on, the right outer peripheral symbol 61b is displayed in white. Accordingly, the extended image IE1 is not displayed, and the extended image IE2 remains displayed. Note that the idle stop mode of the vehicle is a mode in which vehicle control is performed so that the engine is automatically stopped temporarily when the vehicle is stopped waiting for a signal, for example.

  As shown in FIGS. 10 and 11, when the auto cruise mode is set as the display type D in the vehicle, the gear position is displayed on the left side of the display surface 40a and the vehicle speed is displayed on the right side in the character image ILT. In addition, the state of the road such as whether or not a vehicle is present ahead is displayed at the center of the display surface 40a. In this display, the image display panel 40 displays an extended image IEA that is linearly provided so as to further extend the lower end portion 62a of the end portions 62a and 63a of the outer peripheral design 61a. Similarly, the image display panel 40 displays an extended image IEB that is linearly provided so as to further extend the lower end portion 62b of the end portions 62b and 63b of the outer peripheral symbol 61b. Each extended image IEA, IEB is extended from the occupant by linearly extending from the corresponding end portions 62a, 62b toward the center of the display surface 40a, with the vehicle image ICA in the display of the road condition sandwiched between the left and right sides. It can be recognized as an image representing a roadway outer line (for example, white line).

  These extended images IEA, IEB and outer peripheral symbols 61a, 61b are displayed in white as shown in FIG. 10 when the periphery monitoring device has not detected an obstacle in the vicinity. On the other hand, when the periphery monitoring device detects an obstacle on the side outside the vehicle, only the extended image and the outer peripheral pattern on the side where the obstacle is detected on the left and right sides are colored amber (orange) as shown in FIG.

For example, in FIG. 11, since an obstacle is detected on the right side outside the vehicle, only the right extended image IEB and the outer peripheral symbol 61b are changed to amber (orange). In FIG. 11, the color-changed portion is expressed by dot hatching.

  As shown in FIG. 12, as the display type E, when the vehicle continues to travel on the highway for a long time, the gear position is displayed on the left side of the display surface 40a and the speed of the vehicle is displayed on the right side. At the same time, an image prompting a break is displayed in the center of the display surface 40a. At this time, the image display panel 40 further extends the lower ends 62a and 62b of the outer peripheral symbols 61a and 61b, and is an extension provided linearly so as to connect the lower ends 62a and 62b. The image IE1 is displayed. In addition, the image display panel 40 further extends the upper end portions 63a and 63b of the outer peripheral symbols 61a and 61b, and extends the image IE2 provided in a linear shape so as to connect the upper end portions 63a and 63b. Is displayed. For this reason, the image prompting the break is visually recognized as being surrounded by the extended images IE1 and IE2 and the outer peripheral symbols 61a and 61b. These extended images IE1 and IE2 and the outer peripheral symbols 61a and 61b are displayed in amber (orange) for alerting, respectively.

  As described above, the vehicle display device 100 performs display in which the image of the image display panel 40 and the symbols 60 a and 60 b formed by the reflective element 56 are linked.

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

  When the vehicular display device 100 includes the configuration as in the first embodiment, the image display panel 40 is not arranged in a line in the same plane with respect to the dial plate 20, but on the back side of the dial plate 20. Therefore, the depth of the image display panel 40 with respect to the dial plate 20 and the light-transmissive display plate 50 is increased as compared with the side-by-side state. Then, the image on the image display panel 40 can reach the direction of the light transmissive display plate 50 through the transmissive region 24 of the dial plate 20. As described above, the depth perception of the image display panel 40 is increased, so that in the combination of the display by the reflecting portions 54 a and 54 b of the dial plate 20 and the light transmissive display plate 50 and the display of the image display panel 40, the relative A special effect of improving the three-dimensional effect can be expected.

  Further, according to the first embodiment, the plurality of reflective elements 56 are arranged in the side-by-side direction ED of the light transmissive display board 50 to constitute the symbols 60a and 60b. Since the symbols 60a and 60b are displayed as if they protrude from the image display panel 40 to the viewing side, the stereoscopic effect becomes more special.

  Further, according to the first embodiment, the image display panel 40 has the extended images IEA, IEB, IE1, which are linearly provided so as to further extend the ends of the linear outer peripheral symbols 61a, 61b. IE2 is displayed. The extension images IEA, IEB, IE1, and IE2 appear to be continuous with the outer peripheral symbols 61a and 61b, so that the three-dimensional effect is generated and the index portion 22, the reflection portions 54a and 54b, and the image display panel 40 are connected. A sense of unity is obtained in between.

  Further, according to the first embodiment, since the light source 70 includes a color light source that can change the colors of the symbols 60a and 60b, it is possible to produce various appearances according to the situation while producing a stereoscopic effect.

(Second Embodiment)
As shown in FIGS. 13-15, 2nd Embodiment of this invention is a modification of 1st Embodiment. The second embodiment will be described with a focus on differences from the first embodiment.

  In the second embodiment, as shown in FIGS. 13 and 14, as the indicator portion 222, characters and scales representing the engine speed are displayed in the left region of the dial 220, and characters and scales representing the vehicle speed are displayed in the right region. Has been placed. Accordingly, two pointers 30 are provided in total, one corresponding to the left area of the dial 220 and one corresponding to the right area.

  Similar to the first embodiment, the image display panel 40 faces the back side of the dial plate 220 and is arranged corresponding to the central region of the dial plate 220. The central area of the dial plate 220 is set as the transmission area 24 so that the display light of the image on the image display panel 40 is transmitted.

  The light transmissive display board 250 of 2nd Embodiment has the two reflection parts 254a and 254b so that different pattern 260a, 260b may be comprised. The reflection portion 254a is provided at a location facing the upper region of the image display panel 40 in the light transmissive display panel 250. The reflection part 254b is provided in the location which opposes the area | region below the image display panel 40 among the translucent display boards 250. FIG.

  The display panel light source 270 of the second embodiment includes two light emitting units 272a and 272b. The light emitting unit 272a corresponds to the reflecting unit 254a. In the light emitting portion 272 a, each light emitting element 273 a is opposed to the side surface of the outer edge portion 252 on one side of the outer edge portion 252 of the light transmissive display panel 250. Each light emitting element 273a emits light source light toward the side surface, so that the light source light travels from the upper side to the lower side in the light transmissive display panel 250.

  The reflection surface 257a of each reflection element 256a in the reflection part 254a faces the upper side which is the same direction. That is, the light emitting portion 272a is disposed at a position facing the reflecting surface 257a of the corresponding reflecting portion 254a in the outer edge portion 252. When the light source light reaches the reflecting part 254a from the light emitting part 272a, the light source light is reflected to the viewing side by the reflecting surface 257a of each reflecting element 256a facing the light emitting part 272a. Therefore, when the light emitting unit 272a is turned on, the symbols 260a are lit and displayed by the reflecting elements 256a arranged in the reflecting unit 254a.

  The light emitting unit 272b corresponds to the reflecting unit 254b. In the light emitting portion 272 b, each light emitting element 273 b faces the side surface of the outer edge portion 252 on one side on the left side of the outer edge portion 252 of the light-transmitting display panel 250. Each light emitting element emits light source light toward the side surface so that the light source light travels from the left side to the right side in the light-transmitting display panel 250.

  The reflecting surface 257b of each reflecting element 256b in the reflecting portion 254b faces the left side which is the same direction. That is, the light emitting part 272b is arranged at a position facing the reflecting surface 257b of the corresponding reflecting part 254b in the outer edge part 252. Thus, the reflecting surface 257a of the reflecting portion 254a and the reflecting surface 257b of the reflecting portion 254b are oriented in directions different from each other by 90 degrees as shown in FIG.

  When the light source light reaches the reflecting portion 254b from the light emitting portion 272b, the light source light is reflected to the viewing side by the reflecting surface 257b of each reflecting element 256b facing the light emitting portion 272b. Therefore, when the light emitting unit 272b is turned on, the symbols 260b are lit and displayed by the reflecting elements 256b arranged in the reflecting unit 254b.

  With the arrangement of the light emitting units 272a and 272b and the reflecting units 254a and 254b, the light from the light emitting unit 272a can reach the reflecting unit 254b. Are facing different directions, not facing the light emitting portion 272a. Therefore, even when the light emitting unit 272a is turned on, the display of the symbol 260b by the reflecting unit 254b is suppressed.

  Here, the pattern 260a configured by the reflection unit 254a includes a contour pattern 261a in which an appearance contour is expressed among the display objects. In particular, the display object of the present embodiment is a vehicle, and the contour pattern 261a represents the outer contour of the vehicle.

  The symbol 260b configured by the reflecting portion 254b represents a vehicle, but this is a vehicle overhead symbol 261b obtained by looking down at the vehicle from the rear and from above.

  FIG. 13 shows a state in which the light emitting unit 272a is turned on and the light emitting unit 272b is turned off. In this state, the outline symbol 261a is displayed, but the vehicle overhead view symbol 261b is not displayed. Correspondingly, the image display panel 40 displays the internal image IIS in which the internal state is expressed among the display objects so as to be superimposed on the contour symbol 261a. In particular, in the present embodiment, since the display object is a vehicle, the internal image IIS represents the internal state of the vehicle. For example, the internal image IIS displays the engine and storage battery at a position that matches the contour pattern 261a, and the control of the vehicle hybrid system is now controlled by a moving image in which energy flows between the engine, the electric motor, and the storage battery. Is displayed.

  FIG. 14 shows a state in which the light emitting unit 272a is turned off and the light emitting unit 272b is turned on. In this state, the outline symbol 261a is not displayed, but the vehicle overhead view symbol 261b is displayed. Correspondingly, the image display panel 40 displays a navigation image INV in which surrounding roads and streets are expressed. When the navigation image INV displays, for example, an arrow that turns to the right, it is possible to navigate the occupant to the destination.

  According to the second embodiment described above, the reflecting surfaces 257a and 257b face the same direction in the same reflecting portion 254a or 254b, and face different directions between different reflecting portions 254a and 254b. Corresponding to each of the reflecting portions 254a and 254b, the light emitting portions 272a and 272b emit light toward the reflecting surfaces 257a and 257b facing each other. In this way, it is possible to display a plurality of different symbols 260a and 260b on the same light-transmissive display panel 250 by individually turning on or off the light emitting units 272a and 272b.

  In addition, according to the second embodiment, the image display panel 40 superimposes the internal image IIS representing the internal state of the display object as an image on the outline design 261a representing the appearance outline of the display object. To display. According to such superposition display, the contour symbol 261a is displayed as if it protrudes to the viewing side, so that the vehicle occupant can accurately recognize the display object by the appearance contour. And since an internal state is separately displayed on the back side, the vehicle occupant can avoid being confused with the appearance outline and can accurately recognize the internal state. In this way, a display with high visibility utilizing a three-dimensional effect can be realized.

(Third embodiment)
As shown in FIGS. 16 and 17, the third embodiment of the present invention is a modification of the first embodiment. The third embodiment will be described with a focus on differences from the first embodiment.

  As shown in FIG. 16, the display panel light source 370 of the third embodiment includes two light emitting portions 372a and 372b spaced apart from each other, as in the first embodiment. However, in the third embodiment, in each light emitting portion 372a, 372b, each light emitting element 373a, 373b is opposed to the side surface of the outer edge portion 352 on one side on the upper side of the outer edge portion 352 of the light transmissive display plate 350. Yes. Each light emitting element 373a, 373b emits light source light toward the side surface, so that the light source light advances from the upper side to the lower side of the light-transmissive display panel 50.

  Two reflecting portions 354a and 354b are arranged corresponding to the left and right light emitting portions 372a and 372b, respectively. Each reflection part 354a, 354b has a gradation area GRD. As schematically shown in FIG. 17, in the gradation region GRD, at least one of the recess size of the reflective element 56 or the density of the reflective element 56 gradually changes depending on the location. Since the amount of the light source light from the light emitting units 372a and 372b reflected to the viewing side varies depending on the location, the display brightness of the symbols 60a and 60b by the reflective elements 56 changes in a gradation in the gradation region GRD. It becomes. In FIG. 16, gradation is schematically expressed by changing the thickness of the hatched area.

  According to the third embodiment described above, the reflecting portions 354a and 354b have the gradation region GRD in which the display luminance of the symbols 60a and 60b is changed to a gradation by gradually changing the shape or density of the reflecting element 56. Therefore, the stereoscopic effect can be emphasized.

(Fourth embodiment)
As shown in FIGS. 18-22, 4th Embodiment of this invention is a modification of 1st Embodiment. The fourth embodiment will be described with a focus on differences from the first embodiment.

  The display panel light source 470 of the fourth embodiment has a single light emitting section 472 as shown in FIGS. In the light emitting portion 472, each light emitting element 473 faces the side surface of the outer edge portion 452 on one lower side of the outer edge portion 452 of the light transmissive display panel 450.

  On the other hand, the light source control unit 483 of the fourth embodiment individually switches on and off for each light emitting element 473 of the light emitting unit 472.

  The reflective portion 454 of the fourth embodiment is provided including a portion of the light transmissive display plate 450 that faces the image display panel 40. In particular, the reflective portion 454 of the present embodiment is provided including a portion facing the lower side of the image display panel 40. More specifically, the reflecting portion 454 is provided at a location facing the lower side of the dial 20.

  In the fourth embodiment, the symbol 460 formed by each reflecting element 56 of the reflecting portion 454 is a ground symbol 461 representing the ground. Specifically, the ground pattern 461 has a plurality of horizontal lines extending parallel to the left and right, and vertical lines extending vertically and narrowing toward each other as they go upward. And the perspective of the ground is expressed by the horizontal line and the vertical line constituting the ground symbol 461 in a grid pattern.

  With respect to such a ground symbol 461, each light emitting element 473 is arranged along the outer edge portion 452, so that it is directed toward a part of the ground symbol 461 that is shifted in the direction in which the light emitting elements 473 are arranged. It comes to emit light. Thereby, it becomes possible to display only a part of the ground symbol 461 corresponding to the light emitting element 473 to be lit.

  The image display panel 40 of the fourth embodiment can display a moving object image IMV in which a moving object is expressed. In particular, in the present embodiment, since a vehicle is employed as the moving body, the moving body image IMV is a vehicle image representing the vehicle.

  Processing executed by the vehicle display device 400 (mainly the image control unit 482 and the light source control unit 483) of the fourth embodiment will be described based on the flowchart of FIG. At the start of the flowchart of FIG. 22, it is assumed that the image on the image display panel 40 is in a non-display state and the vehicle start switch 402 is in an off state. The start switch 402 is slightly different depending on the vehicle. For example, the start switch 402 corresponds to an ignition switch for starting the engine or a power switch for an electric vehicle.

  First, in step S410, it is determined whether or not the vehicle start switch 402 has been changed from an off state to an on state. If an affirmation judging is made at Step S410, it will move to Step S420. If a negative determination is made in step S410, the determination in step S410 is performed again after a predetermined time or according to a predetermined trigger.

  In step S420, as shown particularly in FIGS. 18 and 20, in the image control unit 482, the moving body image IMV fades in from the right side of the display surface 40a toward the center. In conjunction with the fade-in, the light source control unit 483 sequentially switches the light emitting element 473 to be lit from the left light emitting element 473 to the right adjacent light emitting element 473. That is, the light emitting element 473 to be lit is shifted in the direction opposite to the moving direction of the moving body image. In this way, it is possible to produce an effect as if the vehicle as a moving body is traveling. After the process of step S420, the process proceeds to step S430.

  In step S430, as shown particularly in FIGS. 19 and 21, when the moving body image IMV moves to the center of the display surface 40a, the image control unit 482 displays the moving body image while stopping at the center. Similarly to step S420, the light source control unit 483 sequentially switches the light emitting element 473 to be lit from the left light emitting element 473 to the right adjacent light emitting element 473. For example, the light source control unit 483 shifts the light emitting elements 473 that are sequentially turned on so that the three light emitting elements 473 that are continuously arranged are turned on between the light emitting elements 473 that are turned off. In this way, even if the moving body image IMV is stopped without moving, it is possible to produce an effect as if the vehicle as the moving body is traveling. A series of processing is complete | finished by step S430.

  According to the fourth embodiment described above, among the plurality of light emitting elements 473 that emit light toward a part shifted from each other, the light emitting element 473 to be lit is switched. By such switching, the symbol 460 is partially displayed, and the symbol 460 can be moved and the stereoscopic effect can be emphasized.

  Moreover, according to 4th Embodiment, according to the mobile body image IMV which the image display panel 40 displays, the light emitting element 473 to light is switched to the adjacent light emitting element in order. In this way, the displayed part of the ground symbol 461 appears to move, so that the moving object image IMV can be seen as if it is moving. Therefore, the cooperation between the ground symbol 461 by the reflection unit 454 and the moving body image IMV by the image display panel 40 can create a sense of unity as well as a three-dimensional effect.

(Fifth embodiment)
As shown in FIGS. 23 and 24, the fifth embodiment of the present invention is a modification of the first embodiment. The fifth embodiment will be described with a focus on differences from the first embodiment.

  A vehicle equipped with the vehicle display device 500 of the fifth embodiment includes a moving obstacle detection unit 503 that detects a moving obstacle. The moving obstacle detection unit 503 includes at least one peripheral monitoring sensor such as a millimeter wave radar, sonar, lidar (LIDER: Light Detection and Ranging / Laser Imaging Detection and Ranging), for example, and a moving obstacle such as a pedestrian around the vehicle. An object can be detected.

  The display panel light source 570 of the fifth embodiment has one light emitting unit 572. In the light emitting portion 572, the light emitting elements 573 are arranged on one side on the upper side of the outer edge portion 552 of the light transmissive display panel 550 and face the side surface of the outer edge portion 552.

  On the other hand, the light source control unit 582 of the fifth embodiment individually switches on and off for each light emitting element 573 of the light emitting unit 572. In addition, the light source control unit 582 of the fifth embodiment can communicate with the moving obstacle detection unit 503 via, for example, the ECU of the vehicle.

  In the fifth embodiment, the symbol 60 constituted by each reflecting element 56 of the reflecting portion 554 becomes a moving obstacle motion symbol 561 expressed by arranging a plurality of moving obstacles in the direction in which the light emitting elements 573 are arranged. Yes. Specifically, the moving obstacle motion symbol 561 of the present embodiment is a symbol that represents a state where a pedestrian as a moving obstacle crosses a pedestrian crossing for each motion.

  With respect to such a moving obstacle motion symbol 561, the light emitting elements 573 are arranged along the outer edge portion 552, so that a part of the symbols 561 that are shifted from each other in the direction in which the light emitting elements 573 are arranged. Light is emitted toward the. Thereby, it becomes possible to display only one motion corresponding to the light emitting element 573 to be lit among the moving obstacle motion symbols 561.

  Processing executed by the vehicle display apparatus 500 (mainly the light source control unit 582) of the fifth embodiment will be described based on the flowchart of FIG.

  First, in step S510, the light source control unit 582 determines whether or not a pedestrian 504 moving left and right ahead of the vehicle is detected based on an input signal from the moving obstacle detection unit 503. If a positive determination is made in step S510, the process proceeds to step S520. If a negative determination is made in step S510, the determination in step S510 is performed again after a predetermined time or according to a predetermined trigger.

  In step S520, the light source control unit 582 sequentially switches the light emitting element 573 to be lit to the adjacent light emitting element 573 according to the moving direction of the pedestrian 504. If it does in this way, in the movement obstacle motion design 561, the motion of the pedestrian displayed will change sequentially, and the effect that a pedestrian walks like a flip book can be performed.

  Here, the light source control unit 582 may switch the light emitting elements 573 so that the luminance gradually changes, instead of instantaneously switching on and off. If it does so, the motion adjacent to the motion with the highest display brightness | luminance will be expressed like an afterimage, and the appearance improves.

  In addition, when the pedestrian 504 stops in the middle of the pedestrian crossing, the light source control unit 582 may temporarily stop switching the light emitting element 573 to be lit in conjunction with the temporary stop. After the process of step S520, the process proceeds to step S530.

  In step S530, the light source control unit 582 determines whether the detected pedestrian 504 has moved from the front outside the vehicle to another location. If an affirmation judging is made at Step S530, it will move to Step S540. If a negative determination is made in step S530, the display of the moving obstacle motion symbol 561 is continued, and the determination in step S510 is performed again after a predetermined time or according to a predetermined trigger.

  In step S540, the light source control unit 582 turns off all the light emitting elements 583 and ends the display of the moving obstacle motion symbol 561. A series of processes are complete | finished by step S540.

  According to the fifth embodiment described above, the light emitting element 573 to be lit is switched among the plurality of light emitting elements 573 that emit light toward a part shifted from each other. By such switching, the symbol 561 is partially displayed, the symbol 561 can be moved, and the three-dimensional effect can be emphasized.

  Further, according to the fifth embodiment, when the moving obstacle detection unit 503 detects the pedestrian 504 as the moving obstacle, the light emitting element 573 that is lit up to the adjacent light emitting element 573 according to the pedestrian 504. It switches in order. In this way, the expression of the pedestrian 504 expressed in the moving obstacle motion pattern 561 is displayed in order, and the presence of the pedestrian 504 can be accurately displayed to the vehicle occupant.

(Sixth embodiment)
As shown in FIGS. 25 to 31, the sixth embodiment of the present invention is a modification of the first embodiment. The fifth embodiment will be described with a focus on differences from the first embodiment.

  In the vehicular display device 600 according to the sixth embodiment, as shown in FIGS. 25 and 26, the light transmissive display plate 650 is formed in a curved plate shape using, for example, a light transmissive synthetic resin. Specifically, the viewing-side surface 651 of the light-transmitting display board 650 is formed in a curved shape with a central portion recessed toward the back side. In particular, the surface 651 on the viewing side of the present embodiment has a cylindrical surface curved in the left-right direction of the vehicle.

  External light such as sunlight or light from a light source in the vehicle may enter the light transmissive display board 650 from the viewing side, and the external light is reflected on the light transmissive display board 650. Sometimes. Here, the difference in the light reflection direction between the case where the light-transmitting display plate has a flat plate shape and the case of a curved plate shape will be described with reference to FIG. FIG. 27 shows a cross section of the vehicle display device 600 in the left-right direction. In FIG. 27, a range indicated by an ellipse is referred to as an iris ELP. The Eye Lips ELP shows an eye range that statistically represents the distribution of the position of the eyes of the driver as a passenger as an ellipse (for details, see JIS D0021: 1998).

  In the case of a flat light-transmitting display panel (see the broken line in FIG. 27), a case where predetermined external light Ai is incident on the outer peripheral portion in the right region of the light-transmitting display panel is considered. The incident angle of the external light Ai with respect to the flat light-transmitting display panel is α, and the locus of the reflected light Ar circumscribes the right-eye eye ELP ELP. The reflected light Cr of the external light Ci that is incident at an incident angle γ that is slightly larger than the incident angle α of the external light Ai passes through the left side of the reflected light Ar, and therefore passes through the iris ELP. That is, external light incident on the right region at an incident angle larger than the incident angle α is highly likely to be visually recognized by a driver as an occupant.

  On the other hand, in the case of the light transmitting display plate 650 having a curved plate shape (see the solid line in FIG. 27), when the external light Bi having the same locus as the external light Ai, the outer peripheral portion in the right region of the light transmitting display plate 650 is incident. think of. In this case, since the viewing-side surface 651 is inclined so that the viewing-side surface 651 is slightly directed toward the center portion in the right region due to the curvature of the viewing-side surface 651, the external light Ai with respect to the light transmitting display plate 650 having a curved plate shape. The incident angle is β, and the incident angle β is considerably larger than the incident angles α and γ. For this reason, the trajectory of the reflected light Br passes further to the left than the left eye's eyelips ELP. Furthermore, even if incident light of external light having the same trajectory as the external light Ci is incident, the reflected light passes further to the left of the reflected light Br. This is lower than that of a flat light-transmitting display panel.

  In addition, the light transmissive display board 650 of the sixth embodiment is provided with a through hole corresponding to the pointer 630. Since the connecting portion 632 of the pointer 630 passes through the through hole of the light transmissive display plate 650, the indication portion 634 of the pointer 630 is closer to the viewing side than the light transmissive display plate 650, as shown in FIGS. Is arranged.

  The dial plate 620 of the sixth embodiment is formed in a curved plate shape that has substantially the same curved shape as the light-transmitting display plate 650. The dial plate 620 and the light-transmitting display plate 650 are arranged close to each other with a small gap.

  The dial 620 is formed with an index portion 622 similar to that of the first embodiment. As shown in FIG. 25, in this embodiment, a scale and letters are arranged in the left region of the dial plate 620 as an index 622a representing a situation corresponding to the current value of the electric motor of the vehicle. A scale and characters are arranged as an index 622b for displaying the voltage value of the power battery of the electric motor of the vehicle in the right region of the dial 620.

  The symbol 660 of the sixth embodiment has another indicator portion 659 provided in a region facing the indicator portion 622 in the left and right regions. The separate indicator unit 659 is similar to the indicator unit 622 in that the information is displayed when instructed by the instruction unit 634 of the pointer 630, but displays different information from the information displayed by the indicator unit 622. It has become.

  As shown in FIGS. 25 and 28, the different indicator section 659 of the present embodiment has an indicator symbol 661a in a region facing the indicator 622a, and has an indicator symbol 661b in a region facing the indicator 622b. The index symbol 661a has a scale and characters representing the speed of the vehicle. The index symbol 661b has a scale and characters representing the engine speed of the vehicle.

  The light source control unit 683 of the sixth embodiment can control the indicator illumination light source 627 together with the display panel light source 670. The indicator illumination light source 627 includes a plurality of indicator illumination light emitting elements 628 similar to those of the first embodiment. Specifically, the light source control unit 683 switches between turning on and off each light emitting element 673 of the display panel light source 670 and switching between turning on and off each light emitting element 628 of the indicator illumination light source 627.

  Similar to the first embodiment, the symbol 660 is in a display state when each light emitting element 673 is lit, and can be visually recognized from the viewing side. However, the pattern 660 is not displayed when each light emitting element 673 is turned off, and is hardly visible from the viewing side.

  In addition, the indicator portion 622 of the dial 620 is in a display state when each light emitting element 628 is lit, and can be visually recognized from the viewing side. However, when each light emitting element 628 is turned off, the indicator portion 622 is in a non-display state, and is hardly visible from the viewing side.

  The light source control unit 683 turns on one of the light emitting elements 673 of the display panel light source 670 and the light emitting element 628 of the indicator illumination light source 627 and turns off the other. As a result, only one of the another indicator portion 659 of the light-transmitting display board 650 and the indicator portion 622 of the dial plate 620 is in the display state.

Is stopped and is in a non-display state (see FIG. 31).

  According to the sixth embodiment described above, the light transmissive display board 650 is formed in a curved plate shape. In this way, a part of the light transmissive display board 650 protrudes toward the viewing side with respect to the other areas, so that a stereoscopic effect can be generated in the light transmissive display board 650.

  Further, according to the sixth embodiment, the viewing-side surface 651 of the light-transmitting display plate 650 is formed in a curved shape with a central portion recessed toward the back side. If it does in this way, a three-dimensional effect will arise between the center part and outer peripheral part of the translucent display board 650. FIG. At the same time, since it is possible to suppress the reflected light when external light is reflected by the surface 651 from being visually recognized by the occupant, the visibility of each display is increased, and the relative stereoscopic effect due to the combination of these displays is increased. Can be emphasized.

  Further, according to the sixth embodiment, the display state of the pattern 660 is changed depending on the lighting state of the display panel light source 670, and the indication target indicated by the indication unit 634 is switched between the indicator unit 622 and the separate indicator unit 659. . In such switching, the range of display expression can be expanded by switching the indication target by the same pointer 630.
