  The projector 61 of the HUD 60 has a liquid crystal display 62 and a projection light source 63. The liquid crystal display 62 is a TFT display, for example. The liquid crystal display 62 is connected to the control unit 20 and drives each pixel based on a control signal output from the control unit 20. Various images displayed in color in the virtual image display area 111 are formed on the liquid crystal display 62 (see FIG. 8). The projection light source 63 has, for example, a plurality of high-brightness LEDs. The projection light source 63 is connected to the control unit 20, and emits light formed as a virtual image 35 (see FIG. 2) toward the liquid crystal display 62 based on a control signal output from the control unit 20. .

  The linear light emitting unit 81 of the light emitting unit 80 has a plurality of linked line light sources 89 as point light sources. The link line light source 89 is, for example, an LED or the like, and emits chromatic light such as blue. Each link light source 89 is connected to the control unit 20 and emits light individually based on a control signal output from the control unit 20.

  The mechanical configuration of the linear light emitting unit 81 will be described in detail with reference to FIGS. 4 and 5. The two linear light emitting units 81 are fitted in concave housing grooves 123 (see FIG. 2) formed in the hood portion 121 in an arrangement in the vehicle width direction WD (see FIG. 8). The two linear light emitting units 81 are attached to the hood part 121 in a posture slightly inclined with respect to an axis parallel to the front-rear direction of the vehicle so as to be close to each other toward the front of the vehicle. In addition, in a state where the linear light emitting unit 81 is accommodated in the accommodating groove 123, the light emitting surface 81 a that emits light in the linear light emitting unit 81 is substantially flush with the upper surface of the hood portion 121.

  The linear light emitting unit 81 includes a light source substrate 88, a light guide 84, and a coating film 86 in addition to the above-described linkage light source 89. The light source substrate 88 is formed in a band plate shape having the extending direction of the linear light emitting unit 81 as a longitudinal direction. On the mounting surface 88a of the light source substrate 88, a connector and the like used for connection to the plurality of linkage light sources 89 and the control unit 20 (see FIG. 3) are mounted. The plurality of link line light sources 89 are arranged on the mounting surface 88 a while being spaced apart from each other along the extending direction of the linear light emitting unit 81.

  The light guide 84 is formed in a quadrangular prism shape from a colorless and transparent translucent material such as acrylic resin and polycarbonate resin. The light guide 84 is formed with a holding surface 84b, a light source accommodation chamber 84a, and an emission surface 85. The holding surface 84b is a side surface of the light guide 84 that faces the mounting surface 88a. The holding surface 84b holds the light source substrate 88. The light source accommodation chamber 84a is a space formed by recessing the central portion of the holding surface 84b in a concave shape. The light source accommodation chamber 84 a extends along the extending direction of the light guide 84. A plurality of linkage light sources 89 are accommodated in the light source accommodation chamber 84a. The exit surface 85 is a side surface of the light guide 84 that is located on the opposite side of the holding surface 84b. The emission surface 85 is slightly curved according to the shape of the upper surface of the hood portion 121. The emission surface 85 emits the light from the link line light source 89 incident on the light guide 84 in the upward direction UD.

  The coating film 86 is formed in a film shape and covers the emission surface 85. The texture of the coating film 86 such as the color and surface texture is matched with the texture of the upper surface of the hood 121 around the accommodation groove 123. In the coating film 86, a large number of minute through holes 87 that penetrate the coating film 86 in the thickness direction are formed. The size of the through hole 87 is defined so that the viewer sitting on the driver's seat makes the through hole 87 difficult to view. The inner method of the through hole 87 is, for example, about 1 millimeter or less. The through hole 87 can pass the light emitted from the emission surface 85.

  With the above configuration, when all the link light sources 89 are off, the light emitting surface 81a is difficult to distinguish from the upper surface of the hood portion 121. On the other hand, when the link line light source 89 is in the lighting state, the linear light emitting unit 81 emits light by emitting light from the link line light source 89 that has passed through the through hole 87 from the light emitting surface 81a. And as above-mentioned, the connection line light source 89 is set so that lighting and extinction may be controlled by the control part 20 individually. As a result, as will be described later, the light emitting position is visually observed on the light emitting surface 81a so as to move on the light emitting surface.

  Here, the steering switch 130 used for operating the display of the display device 100 (see FIG. 1) will be described with reference to FIGS. The configuration in which the display operation is input is not limited to the steering switch 130, and may be, for example, a joystick and a touch panel provided on the center console.

  The steering switch 130 is disposed in the steering wheel 130a in a range where a finger that grips the rim portion can easily reach, for example, a spoke portion. The steering switch 130 is formed in a circular shape as a whole, and includes an enter key 132 and four direction keys 131u, 131d, 131l, and 131r.

  The enter key 132 is formed in a circular shape and is arranged at the center of the steering switch 130. Each of the direction keys 131u to 131r is one of the steering switch 130 that is obtained by equally dividing the region on the outer peripheral side of the enter key 132 into the circumferential direction. Each direction key 131u to 131r is assigned with each direction of up, down, left and right. An operator (viewer) who operates the steering switch 130 can select a desired item from among a plurality of items by pressing the direction keys 131u to 131r, and can confirm the selection by pressing the enter key 132. An operation request output from the steering switch 130 based on such an operation is acquired by the control unit 20 through the in-vehicle LAN 140 shown in FIG.

  By operating the display of the multi-display area 11 with the input to the steering switch 130 as described above, the viewer can select the image displayed in the virtual image display area 111. Hereinafter, an operation in the HUD customization mode for changing the display of the virtual image display area 111 and a change in the display of the display device 100 due to the operation will be described based on FIGS. 8 and 9 with reference to FIG.

  First, display by the light emitting unit 80 in the HUD customization mode will be described with reference to FIG. FIG. 8 shows the entirety of a plurality of display areas visually recognized by a driver (viewer) seated in the driver's seat. From the viewpoint of the viewer, the light emitting unit 80 is located in a range between the multi display area 11 and the virtual image display area 111 in the hood 121. Each linear light-emitting unit 81 extends linearly from the multi-display area 11 toward the virtual image display area 111 in terms of appearance from the viewer. Of the both ends of each linear light emitting unit 81 in the extending direction, each one end that is located in the rearward direction of the vehicle and is apparently close to the multi display area 11 is referred to as a rear end 82. Further, out of both ends of each linear light emitting unit 81 in the extending direction, each other end that is located in the front direction of the vehicle and is apparently close to the virtual image display region 111 is referred to as a front end 83. From the viewpoint of the viewer, the distance d1 between the rear end portions 82 is closer to the length w1 of the multi-display area 11 in the width direction WD than the length w2 of the virtual image display area 111 in the width direction WD. Are substantially aligned with the length w1. Similarly, the interval d2 between the front side end portions 83 is closer to the length w2 of the virtual image display region 111 in the width direction WD than the length w1 of the multi display region 11 in the width direction WD. It is aligned with the length w2.

  The light emitting unit 80 causes a part of the light emitting surface 81 a of each linear light emitting unit 81 to emit light as the light emitting spot 38. The region of the light emitting surface 81a excluding the light emitting spot 38 may emit light with a lower luminance than the light emitting spot 38 or may not emit light. The light emission spot 38 is movable on the light emission surface 81a. In addition, a part of the light emitted from the light emitting surface 81a toward the upward direction UD is in an area UD above the virtual image display area 111 (hereinafter referred to as “reflection display area”) 112 in the windshield 110. Reflected on the driver's seat side. Therefore, the reflection image 36 of the light emission spot 38 by the light emitting unit 80 is displayed in the reflective display area 112.

  Next, display of the multi display area 11 in the HUD customization mode will be described. A setting menu 31 is displayed in the multi-display area 11 in the HUD customization mode. In the setting menu 31, items that can be displayed in the virtual image display area 111 are arranged in the vertical direction of the display. Specifically, items such as “Shift”, “Speed”, “Fuel”, and “TBT (turn-by-turn)” are displayed in the setting menu 31. By operating these items, the display of the virtual image display area 111 such as the shift indicator 35a, the digital speedometer 35b, the fuel gauge 35k, and the turn-by-turn 35d can be switched on and off.

  Specifically, an operation for adding the digital speedometer 35b to the virtual image display area 111 displaying the shift indicator 35a will be described. The viewer selects an item “Speed” from among a plurality of items displayed on the setting menu 31 of FIG. 9A by operating the up and down direction keys 131u and 131d, and selects the item by pressing the enter key 132. decide. Then, each linear light emitting unit 81 displays the light emitting spot 38 on the rear side end portion 82. Thereby, the reflection image 36 of the light emission spot 38 is also displayed in the reflection display area 112.

  As shown in FIGS. 9A and 9B, each light emitting spot 38 moves toward the front end 83 so as to flow on the light emitting surface 81a. In addition, the reflected image 36 also moves in the downward direction DD toward the virtual image display area 111. The movement of the light emitting spot 38 and the reflected image 36 is perceived by the viewer as a linkage line that is displayed in a light emitting manner.

  When each light-emitting spot 38 reaches the front end 83, the shift indicator 35a moves from the center of the virtual image display area 111 toward the left outer edge in order to secure an area for displaying the digital speedometer 35b (see FIG. 9C). Moving. Then, the light emission spot 38 of each light emitting surface 81a disappears, and the digital speedometer 35b is displayed in the virtual image display area 111 as shown in FIG. 9C.

  As described above, in the display device 100 (see FIG. 1), the light emitting unit 80 emits light as the display of the virtual image display area 111 is changed based on an operation request for operating the display of the multi display area 11. . In order to realize such a display change of the display device 100, a process performed by the control unit 20 will be described based on FIG. 10 with reference to FIG. The processing shown in FIG. 10 is started by the control unit 20 based on activation of the HUD customization mode by operating the steering switch 130 or the like. This process is repeatedly performed by the control unit 20 until the viewer ends the HUD customization mode.

  In S101, the operation request output processing to the in-vehicle LAN 140 is performed, and the process proceeds to S102. In S <b> 102, it is determined whether or not the determination key 132 has been operated based on whether or not the operation request acquired in S <b> 101 is due to the pressing operation of the determination key 132. If a negative determination is made in S102 that the enter key 132 has not been operated, the process returns to S101. On the other hand, if it is determined in S102 that the enter key 132 has been operated, the process proceeds to S103.

  In S103, based on the operation request accompanied by the display change of the virtual image display area 111 acquired in S101, a light emission process for causing the light emitting unit 80 to emit light is started. Specifically, the light emission spot 38 shown in FIG. 8 flows from one side of the multi display area 11 and the virtual image display area 111 to the other side (see also FIGS. 9A and 9B), as shown in FIG. The plurality of linkage light sources 89 of each linear light-emitting unit 81 are turned on in order for a certain time. In this way, the light emitting unit 80 starts light emission in a period from when the operation request is acquired by the control unit 20 until the display change of the virtual image display area 111 (see FIG. 8) based on the operation request is started.

  In S104 shown in FIG. 10, a change process for changing the display of the HUD 60 is started. Specifically, the layout of the image drawn on the liquid crystal display 62 is changed so that the image of the item for which the enter key 132 is operated in S101 is displayed. As described above, images displayed as virtual images in the virtual image display region 111 are added or reduced (see FIG. 9C). Here, the HUD display change process in S104 may be started after the light emission process started in S103 is completed, or may be performed in parallel with the process after the light emission process is started.

  According to the present embodiment described so far, when the display of the virtual image display area 111 is changed based on the operation request for operating the display of the multi display area 11, the two display areas 11 are based on the operation request. , 111 emits light. As described above, if the light emitting unit 80 emits light in association with the display change of the virtual image display area 111, the display device 100 is as if an operation request is transmitted from the multi display area 11 to the virtual image display area 111. Remind the viewer of the image. As a result, the viewer's attention can be directed to the virtual image display area 111 without a sense of incongruity. Therefore, the viewer can accurately grasp the change in display in which the two display areas 11 and 111 located apart from each other are linked.

  In addition, as in the present embodiment, the light emitting unit 80 disposed in the hood unit 121 is likely to attract the eyes of the viewer, and thus can reliably exhibit the function of guiding the viewer's attention. Therefore, a change in display in which the two display areas 11 and 111 are linked is more easily recognized by the viewer.

  Further, in the configuration in which the virtual image display area 111 is linked to the multi display area 11 as in the present embodiment, the light emitting unit 80 is positioned between the two display areas 11 and 111 by being positioned in the hood unit 121. Can do. Therefore, the upper surface of the hood part 121 is suitable as a formation place of the light emitting part 80 in the display device 100 that performs virtual image display.

  Further, in the present embodiment, the viewer can visually recognize the light emission of the light emitting unit 80 itself and the reflected image 36 of the light emitting unit 80. Therefore, when changing the display layout of the virtual image display area 111 in the HUD customization mode, it is possible to further emphasize the virtual image display area 111 and guide the viewer's line of sight to the virtual image display area 111. Therefore, the viewer can grasp the change in display in which the two display areas 11 and 111 are linked without omission.

  In addition, in the present embodiment, the light emission spot 38 moves on the light emission surface 81 a from the multi display area 11 toward the virtual image display area 111. Such a display in which the light emitting spot 38 is flowed easily attracts the eyes of the viewer, and can guide the viewer's attention to the virtual image display area 111 without a sense of incongruity. Therefore, the change in display in which the two display areas 11 and 111 are linked is further easily grasped.

  Further, in the present embodiment, the linear light emitting unit 81 extends linearly from the multi display area 11 to the virtual image display area 111 in the appearance of the viewer. Therefore, the movement of the light emitting spot 38 flowing through the elongated light emitting surface 81a formed in the linear light emitting unit 81 can remind the viewer of an image as if an operation request is transmitted through the signal line. As a result, the viewer's attention is guided to the virtual image display area 111 without a more uncomfortable feeling. Therefore, the change of the display in which the two display areas 11 and 111 are linked becomes easier for the viewer.

  Further, in the present embodiment, in the two linear light emitting units 81 arranged in the vehicle width direction WD, the distance d1 between the rear side end portions 82 is aligned with the length w1 of the multi display region 11 in the width direction WD. . In addition, the interval d2 between the front end portions 83 is aligned with the length w2 of the virtual image display region 111 in the width direction WD. According to the above, the two light emitting surfaces 81a form a link line shape that links the two display areas 11 and 111 together. Therefore, the light emission spot 38 flowing through each light emitting surface 81a makes it easier for the viewer to associate the movement of information between the two display areas 11 and 111.

  In addition, the light emitting unit 80 of the present embodiment clearly shows an image of information transmitted from the multi display area 11 to the virtual image display area 111 by starting light emission before the display change of the virtual image display area 111 is started. obtain. Therefore, the effect of the light emitting unit 80 that makes it easy to grasp the change in display in which the two display areas 11 and 111 are linked is even more certain.

  Then, as in the present embodiment, if the coating film 86 having a texture similar to that of the upper surface of the hood portion 121 covers the emission surface 85, the light emitting surface 81a in the extinguished state can be made inconspicuous for the viewer. . Therefore, the deterioration of the appearance around the driver's seat due to the provision of the linear light emitting unit 81 in the hood portion 121 can be prevented. On the other hand, when the connection line light source 89 is in a light emission state, the light emitted from the emission surface 85 passes through a large number of through holes 87 and is emitted to the outside of the coating film 86. Therefore, the light emitting surface 81a can reliably emit light. As described above, the light emitting unit 80 can exert an effect of easily grasping a change in display without adversely affecting the appearance from the viewer.

  In the present embodiment, the multi display area 11 corresponds to the “first display area” and the “operation display area” described in the claims, and the virtual image display area 111 corresponds to the “second display area” described in the claims. It corresponds to “display area” and “linkage display area”.

  In Modification 1 of the above embodiment, the combination meter 210 shown in FIG. 11 forms a pointer display area 215, a right display area 211a, and a left display area 211b. The right display area 211a and the left display area 211b are located away from each other. The viewer of the combination meter 210 can change the image displayed in the left display area 211b by operating the setting menu 231 displayed in the right display area 211a. Therefore, the control unit of the combination meter 210 performs control to change the display of the left display area 211b based on an operation request for operating the display of the right display area 211a.

  In the first modification, the light emitting unit 280 has two linear light emitting surfaces 281 a extending in the width direction WD in the pointer display region 215. The distance between the two light emitting surfaces 281a in the vertical direction is substantially aligned with the height in the vertical direction of the two display areas 211a and 211b. In addition, the texture of the light emitting surface 281 a is matched with the texture of the ground portion of the pointer display area 215. The light emitting unit 280 moves the light emitting spot 38 from the right display region 211a toward the left display region 211b under the control of the control unit.

  Also in the above modification 1, the light emission part 280 light-emits based on the operation request | requirement accompanied by the display change of the left side display area 211b. Therefore, the viewer can recall an image as if an operation request was transmitted from the right display area 211a to the left display area 211b. Then, when the viewer's attention is directed to the left display area 211b by the light emitting unit 280, the change in the display in which the two display areas 211a and 211b are linked can be accurately grasped by the viewer. .

  Further, the formation position of the light emitting part may be on the upper surface of the hood part as in the above embodiment, or may be in the combination meter as in the first modification. In addition, as in the first modification, a light emitting unit that facilitates grasping the linked display of the display areas 211a and 211b in the combination meter 210 is provided in the hood unit 221 positioned in the upward direction UD of the meter 210. It may be. Furthermore, in the form in which the combination meter is placed on the instrument panel, a light emitting unit can be formed on the upper surface of the meter.

  In the above-described embodiment, the HUD customization mode has been described in detail. However, in other operation modes, display in which the two display areas 11 and 111 are linked is performed. For example, in the display movement mode shown in FIG. 12, the display image displayed in the multi display area 11 can be moved to the virtual image display area 111.

  Specifically, FIGS. 12A to 12C show displays when the accelerometer displayed in the multi display area 11 is moved to the virtual image display area 111. The accelerometer visualizes the magnitude of the acceleration generated in the vehicle by acceleration / deceleration and steering by the eccentric amount of the spherical spot displayed in the annular image. For convenience, in the following description, an image displayed in the multi-display area 11 is referred to as “accelerometer 31a”, and a virtual image displayed in the virtual image display area 111 is referred to as “accelerometer 35f”. In addition, the information display which can move between two display areas is not limited to an accelerometer. In addition, the information display can be moved bidirectionally between the two display areas.

  The viewer determines the movement of the accelerometer 31a shown in FIG. 12A to the virtual image display area 111 by pressing the up and down direction keys 131u and 131d (see FIG. 7) and the enter key 132 (see FIG. 7). Then, the light emission spot 38 and its reflection image 36 are displayed. The light emission spot 38 and the reflection image 36 thereof move toward the virtual image display area 111 as shown in FIGS. 12A and 12B.

  In the multi display area 11, each display is toned down, and the accelerometer 31 a moves upward UD so as to match the movement of the light emission spot 38. The accelerometer 31a disappears from the upward direction UD to the outside of the range of the multi display area 11. On the other hand, in the virtual image display area 111, the shift indicator 35a and the digital speedometer 35b move from the center toward the left and right outer edges. In addition, the accelerometer 35 f is inserted into the virtual image display area 111 from the downward direction DD as the accelerometer 31 a moves out of the range of the multi-display area 11.

  As shown in FIG. 12C, the acceleration meter 35f moves to the center of the virtual image display area 111 and is positioned between the shift indicator 35a and the digital speedometer 35b. Thus, the movement of the accelerometers 31a and 35f across the two display areas is completed. As described above, even when the information display is moved from one of the two display areas 11 and 111 to the other, the light-emitting display that causes the light-emitting spot to flow makes it easy for the viewer to grasp the change of the linked display.

  In the above embodiment, the display of the virtual image display area 111 is changed by operating the multi display area 11. However, the display of the multi-display area 11 can be changed by operating the virtual image display area 111. In this case, the virtual image display area 111 corresponds to the “operation display area”, and the multi display area 11 corresponds to the “link display area”. Similarly, in the first modification, it is possible to change the display of the right display area 211a corresponding to the “linked display area” by operating the left display area 211b corresponding to the “operation display area”.

  In the above-described embodiment, light emission of the light emitting unit is started in a period from when the operation request is acquired by the control unit to when the display change of the virtual image display region is started. However, if the display change that moves the shift indicator 35a (see FIG. 9B) is first performed in the virtual image display area, the light emission start of the light emitting unit is more than the start of the display change of the virtual image display area. Can be later. As described above, if the transmission of the operation request can be expressed by the light emission of the light emitting unit, the context between the light emission start timing of the light emitting unit and the timing of starting the display change of the virtual image display region can be adjusted as appropriate. .

  Further, when a new image is added to the virtual image display area, the added image is slid in or faded in from the outer edge of the lower direction DD adjacent to the virtual image display area and the light emitting part in synchronization with the light emission of the light emitting part. It's okay. Thus, by combining the movement of the image with the light emission of the light emitting unit, the viewer can more easily recall the image in which the operation request is transmitted to the virtual image display area.

  In the above embodiment, the reflection image of the light emitting unit is displayed in the reflection display area located in the upward direction UD of the virtual image display area (see FIG. 8). Such display of the reflected image may be omitted. Moreover, the area | region except a light emission spot in the light emission surface may emit light slightly with a brightness | luminance lower than a light emission spot, or it may not emit light substantially by extinction of a link light source.

  Further, although each linear light emitting unit performs display such that a light emitting spot flows, the light emission mode of each linear light emitting unit can be changed as appropriate. For example, instead of the light emission spot, control that the band of light continuously proceeds from the multi-display area toward the virtual image display area, or from the virtual image display area toward the multi-display area, May be implemented. Alternatively, a light emitting mode may be employed in which all of the light emitting surfaces emit light linearly by simultaneously emitting light from a plurality of cooperative line light sources so as to connect two display regions. In addition, the dot-like or band-like light emitting areas projected on the two light emitting surfaces may move differently.

  In the above-described embodiment, a linear light-emitting unit that forms a linear light-emitting surface that displays a link line that connects two display areas is employed as the light-emitting portion. However, the shape of the light emitting surface is not limited to a linear shape. For example, the entire range sandwiched between two display areas on the top surface of the hood portion can be formed as a light emitting surface capable of emitting light. Moreover, also in the form which employ | adopts a linear light emission unit, the number, arrangement | positioning, etc. of the said unit can be changed suitably.

  In the said embodiment, the light emission surface was formed so that it might melt | dissolve in the surrounding structure by coat | covering the injection | emission surface with a coating film. However, the formation of such a coating film may be omitted. Furthermore, a light-emitting surface that is made to stand out from the periphery may be formed by forming a coating film on the emission surface that is greatly different in texture from the surrounding structure.

  In the above embodiment, a light emitting diode is employed as each light source. However, the configuration that can be employed as the light source is not limited to the light emitting diode. For example, a fluorescent tube and an organic EL panel can be used as the light source.

  In the embodiment described above, the windshield of the vehicle is used as the projection unit on which each display image is projected. However, the projection unit is not limited to the windshield. For example, a combiner that is formed in a plate shape with a translucent resin and attached to the upper surface of the instrument panel or the vehicle interior side of the windshield may be installed as a configuration corresponding to the projection unit.

  The projector according to the embodiment has a configuration in which a TFT liquid crystal display and a projection light source are combined. However, the configuration for projecting the display image can be changed as appropriate. For example, a liquid crystal display other than the TFT method can be used. Furthermore, a display image may be projected by a DLP (Digital Light Processing: registered trademark) projector, a CRT projector, or the like. Furthermore, a laser scanner using MEMS (Micro Electro Mechanical Systems) may be included in the “projection unit” as a configuration for projecting a display image.

  In the above embodiment, the function of the “display control means” provided by the control unit 20 that has executed the program may be provided by hardware and software different from the above-described configuration, or a combination thereof. For example, the above-described function of controlling the display of each display area and the light emission of the light emitting unit may be provided by a circuit that performs a predetermined function without depending on a program.

  In the above, the example which applied this invention to the display apparatus mounted in the vehicle and combined with the combination meter, HUD, etc. was demonstrated. However, the present invention is not limited to vehicles, but can be applied to display devices used in various consumer devices, various transport devices, and the like.
