The backlight 14 illuminates the image on the display screen 12 with a light source such as a plurality of light emitting diodes (hereinafter referred to as LEDs). The backlight 14 is connected to the control unit 20, and the luminance of the illumination is controlled by a control signal output from the control unit 20.

  The stepper motor 17 is an electric motor that drives the hands 16. The stepper motor 17 is connected to the control unit 20, and forms a pointer display in the pointer display region 15 by rotating the pointer 16 based on a control signal output from the control unit 20. The indicator light source 19 is, for example, an LED. Each indicator light source 19 is connected to the control unit 20 and emits light for causing each indicator 18 to emit light based on a control signal output from the control unit 20.

  The control unit 20 includes a microcomputer that operates according to a program, an interface that communicates with an in-car local area network (LAN) 140, and a drive circuit that drives the liquid crystal display 13, the stepper motor 17, each light source, and the like. It is configured. In addition to a plurality of in-vehicle devices 150 mounted on the vehicle, a steering switch 130 and the like are connected to the in-vehicle LAN 140. The control unit 20 acquires vehicle information output to the in-vehicle LAN 140, and outputs a control signal based on the acquired information to the liquid crystal display 13, the stepper motor 17, and each light source.

  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 that are displayed in color in the virtual image display area 111 (see FIGS. 7 and 8) are formed on the liquid crystal display 62. 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 based on a control signal output from the control unit 20, the light of the first display image 33 (see FIG. 2) formed as a virtual image 35 (see FIG. 2).

  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. In the present embodiment, the emission color of the link line light source 89 is matched with the emission color of the frame display light source 69. 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.

  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. Note that the configuration in which the display operation is input in the vehicle interior is not limited to the steering switch 130 but may be, for example, a joystick or a touch panel provided in 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.

  Next, details of the operation for changing the display layout of each of the display areas 11 and 111 (see FIG. 1) will be described. In the following description, an operation request output from the steering switch 130 based on input to the direction keys 131u to 131r is referred to as a “change operation request”. The operation request output from the steering switch 130 based on the input to the determination key 132 is referred to as a “decision operation request”. Based on the change operation request, the control unit 20 controls the liquid crystal displays 13 and 62 so that the display layouts of the two display areas 11 and 111 are changed in cooperation. In this way, the HUD customization mode, which is one of the operation modes in which the display of the two display areas 11 and 111 is linked, will be described based on FIG. 7 with reference to FIG.

  In the HUD customization mode, the information displayed in the virtual image display area 111 can be changed by operating the setting menu 31 displayed in the multi display area 11. 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 the item “Shift”, the display of the shift indicator 35 a in the virtual image display area 111 is switched on and off. Further, by operating the item “Speed”, the display of the shift indicator 35 a is switched on and off.

  7A to 7C show a process of changing the display layout when the digital speedometer 35b is added to the virtual image display area 111 displaying the shift indicator 35a. The viewer selects the item “Speed” from among a plurality of items displayed on the setting menu 31 of FIG. 7A by operating the up and down direction keys 131u and 131d. Then, the viewer confirms the “Speed” selection by pressing the enter key 132. Then, the light emitting spot 38 is displayed on the two linear light emitting units 81. In addition, a reflection image 36 of the light emission spot 38 is displayed in the reflection display area 112.

  As shown in FIGS. 7A and 7B, each light emission spot 38 moves from the multi-display area 11 to the virtual image display area 111 in the appearance of the viewer. In addition, each reflected image 36 moves in the downward direction DD so as to approach the virtual image display area 111 in the appearance of the viewer. 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. Each light emitting spot 38 disappears by reaching the end of the light emitting surface 81a close to the virtual image display area 111.

  The shift indicator 35a moves from the center of the virtual image display area 111 toward the left outer edge so as to match the movement of the light emission spot 38. Thereby, an area for displaying the digital speedometer 35b (see FIG. 7C) is secured in the virtual image display area 111. Then, as shown in FIG. 7C, the digital speedometer 35b is displayed at a position adjacent to the shift indicator 35a in the virtual image display area 111.

  When the display layout reflecting the viewer's input operation is confirmed by the display of the digital speedometer 35b, a confirmation notification frame 35e that is a virtual image 35 of the second display image 34 (see FIG. 2) is displayed. The confirmation notification frame 35e is formed on the outer peripheral side of the shift indicator 35a and the digital speedometer 35b, which are virtual images 35 of the first display image 33 (see FIG. 2), as viewed from the viewer. The confirmation notification frame 35e is lit for about 1 second and then turned off. The lighting time of the confirmation notification frame 35e can be changed as appropriate.

  Next, a display movement mode, which is another operation mode in which the displays of the display areas 11 and 111 are linked, will be described with reference to FIG. In the display movement mode, the display image displayed in the multi display area 11 can be moved to the virtual image display area 111. As a specific example, FIGS. 8A to 8C 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 acceleration generated in the vehicle by acceleration / deceleration and steering by the amount of eccentricity of a spherical spot displayed in a disk-shaped 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”.

  The viewer determines the movement of the accelerometer 31a shown in FIG. 8A to the virtual image display area 111 by pressing the up and down direction keys 131u and 131d and the enter key 132. Then, the light emission spot 38 and its reflection image 36 are displayed. The light emission spot 38 and its reflection image 36 move toward the virtual image display area 111 as shown in FIGS. 8A and 8B.

  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. 8C, the acceleration meter 35f moves to the center of the virtual image display area 111 and is located between the shift indicator 35a and the digital speedometer 35b. When the movement of the accelerometer 35f is thus completed, a confirmation notification frame 35e is temporarily displayed on the outer peripheral side of the accelerometer 35f, the shift indicator 35a, and the digital speedometer 35b.

  In order to realize the display change of the display device 100 described above, a process performed by the control unit 20 will be described based on FIG. 9 with reference to FIG. The processing shown in FIG. 9 is started by the control unit 20 based on activation of operation modes such as the HUD customization mode and the display movement mode by the operation of the steering switch 130 or the like. This process is repeatedly performed by the control unit 20 until the viewer ends these operation modes.

  In S101, the operation request output processing to the in-vehicle LAN 140 is performed, and the process proceeds to S102. In S102, it is determined whether or not there is a decision operation request among the operation requests acquired in S101. If a negative determination is made in S102 that the determination operation request has not been acquired, the process returns to S101. On the other hand, if it is determined in S102 that the determination operation request has been acquired, the process proceeds to S103.

  In S103 when the determination operation request is acquired, a light emission process for causing the light emitting unit 80 to emit light is started based on the determination operation request acquired in S101. By the process of S103, the light emission spot 38 flows from one side to the other side of the multi display area 11 and the virtual image display area 111 (see FIG. 7A, FIG. 8A, etc.).

  In S104, based on the change operation request acquired together with the determination operation request in the acquisition process of S101, a change process for controlling the liquid crystal display 62 so as to change the display mode of the first display image 33 is started. move on. Through the process of S104, a digital speedometer 35b, an acceleration meter 35f, and the like are added to the virtual image display area 111 (see FIGS. 7C and 8C).

  In S105, it is determined whether or not the changing process of the first display image 33 started in S104 is completed. If a negative determination is made in S105, the determination in S105 is repeated to wait for the completion of the change process. Then, upon completion of the change process, the process proceeds to S106 on condition that an affirmative determination is made in S105.

  In S106, the lighting process of the confirmation notification frame 35e is performed, and the process returns to S101. By the process of S106, a confirmation notification frame 35e is temporarily displayed around the virtual image 35 of the first display image 33 in the virtual image display area 111 as a display change for notifying the confirmation and completion of the change of the first display image 33. A virtual image is displayed (see FIGS. 7C and 8C).

  In the present embodiment described so far, when an operation for changing the display layout of the virtual image display area 111 is input to the steering switch 130, the control unit 20 acquires an operation request based on the input and moves to the corresponding display layout. The display mode of the virtual image display area 111 is changed. Then, the control unit 20 temporarily lights the confirmation notification frame 35e as a display change for notifying the confirmation of the change to the display layout corresponding to the acquired operation request. The specific display change by the confirmation notification frame 35e is performed separately from the display layout change, so that the viewer has changed the display layout of the virtual image display area 111 to the display mode reflecting the input operation. , You will be able to grasp easily.

  In addition, in this embodiment, notification of change confirmation to the viewer is performed by the display change of the second display image 34 among the first display image 33 and the second display image 34. In this way, by displaying the second display image 34 for notifying the confirmation of the change separately from the first display image 33 whose display layout is changed, the confirmation of the change of the display layout is further understood by the viewer. It can be easily notified.

  In the present embodiment, the virtual image 35 of the first display image 33 and the virtual image 35 of the second display image 34 are formed at positions shifted in the vehicle front-rear direction. Therefore, a stereoscopic effect is imparted to the display of the virtual image display area 111 obtained by combining these virtual images 35. In this way, the three-dimensional virtual image display can strongly exert an action that attracts the eyes of the viewer. As a result, the display change of the confirmation notification frame 35e in the virtual image display area 111 is more easily grasped by the viewer.

  Furthermore, the confirmation notification frame 35e used for the confirmation notification in the present embodiment is a virtual image 35 of the second display image 34 that is directly projected onto the windshield 110 without passing through the optical system 64. Therefore, both the enlargement of the optical system 64 and the reduction of the display size of the digital speedometer 35b and the like can be avoided in order to add the display of the confirmation notification frame 35e. Therefore, it is possible to add a function of notifying the viewer of the confirmation of the layout change while maintaining the high information providing function of the HUD 60 that presents vehicle information to the viewer.

  In addition, in this embodiment, since the frame display 66 is provided around the opening 65a, a large optical path difference may be generated between the light of the first display image 33 and the light of the second display image 34. Therefore, the distance between the digital speedometer 35b and the like and the confirmation notification frame 35e is more easily secured. As described above, the virtual image display in which the stereoscopic effect is emphasized further attracts the viewer's eyes, so that the display change for performing the notification of confirmation is further easily grasped by the viewer.

  In this embodiment, since the confirmation notification frame 35e has a frame shape surrounding the digital speedometer 35b and the like, even if the viewer is watching the digital speedometer 35b and the like, the confirmation notification frame 35e misses the confirmation notification. hard. Therefore, the above-described display change in which the frame-shaped confirmation notification frame 35e is turned on is suitable as the display change for performing the confirmation notification.

  Furthermore, in this embodiment, the confirmation notification by turning on the confirmation notification frame 35e is performed after the change of the display layout based on the operation request is completed. Therefore, the lighting of the confirmation notification frame 35e can clearly notify the viewer that the layout change of the first display image 33 has been completed.

  In the display device 100 in which the display of the multi-display area 11 is changed in association with the first display image 33 projected on the virtual image display area 111 as in the present embodiment, the viewer's attention is the multi-display area. 11, it can be easily removed from the virtual image display area 111. As a result, the process of changing the display layout becomes more difficult to perceive. Therefore, in the display device 100 in which the two display areas 11 and 111 are linked, the configuration in which the display layout change confirmation is notified by turning on the confirmation notification frame 35e is particularly effective for improving the usability of the viewer.

  In the present embodiment, the liquid crystal display 13 corresponds to “display means” described in the claims, and the control unit 20 corresponds to “display control means” described in the claims. Further, the HUD 60 corresponds to the “projection means” described in the claims, the projector 61 corresponds to the “first projector” described in the claims, and the frame indicator 66 described in the claims. Corresponds to the “second projector”. The display device 100 corresponds to the “vehicle display device” described in the claims, the windshield 110 corresponds to the “projection unit” described in the claims, and the steering switch 130 corresponds to the claims. This corresponds to the “input unit” described in.

As mentioned above, although one embodiment by the present invention was described, the present invention is not interpreted limited to the above-mentioned embodiment, and is applied to various embodiments and combinations within the range which does not deviate from the gist of the present invention. be able to.

  In the first modification of the above embodiment, when the change of the display layout based on the change operation request is confirmed, all the virtual images displayed in the virtual image display area are temporarily deleted (for example, 1 second or less). The display layout change confirmation can be notified even by such a display change. According to the first modification described above, it is possible to notify the confirmation of the layout change without newly adding a display such as the above-described confirmation notification frame 35e.

  In addition, the display temporarily turned off in the first modification may not be all that is being displayed in the virtual image display area. For example, virtual images other than digital speedometers that are required to be displayed by laws and regulations may be temporarily deleted. Furthermore, confirmation of layout change may be notified to the viewer by a display change that causes the background of the virtual image to emit light in a specific color temporarily.

  The HUD 60 of the above embodiment has the frame display 66 separately from the projector 61, thereby forming the virtual image 35 of the second display image 34 at a position away from the virtual image 35 of the first display image 33. However, the second display image for performing the confirmation notification can be projected by the same projector as the first display image that mainly displays vehicle information.

  In addition, the formation position of the frame display is not limited to the periphery of the opening of the housing. For example, when the frame display is configured integrally with the projector, each light of the first display image and the second display image may pass through the optical system. The frame indicator may be arranged in the housing as a projector separate from the projector. Furthermore, the HUD that projects the first display image and the HUD that projects the second display image may be provided separately. And according to the structure of HUD as mentioned above, the distance between each virtual image of a 1st display image and a 2nd display image may be changed suitably.

  In the above-described embodiment, the shape and display color of the confirmation notification frame that is a broken frame surrounding other display images by L-shaped display images arranged at the four corners of the virtual image display area 111 can be changed as appropriate. . For example, the confirmation notification frame may have a continuous frame shape surrounding the virtual image of the first display image over the entire circumference. Furthermore, the virtual image of the second display image may not be a frame shape. For example, instead of the confirmation notification frame, a confirmation notification bar that extends in a strip shape in the width direction WD of the vehicle may be displayed above or below the virtual image of the first display image. Or the character which notifies the confirmation of layout change may be displayed on a virtual image display area.

  In the above embodiment, the lighting of the confirmation notification frame 35e is started after the layout change is completed. However, the lighting of the confirmation notification frame may be started before the layout change is completed and may continue until after the completion. Alternatively, the confirmation notification frame may be continuously lit while the layout change is continued. In this case, the viewer can surely grasp the completion of the layout change by the display change in which the confirmation notification frame disappears.

  In the above embodiment, when the display layout of the virtual image display area 111 is changed, the lighting of the confirmation notification frame 35e is combined with the movement of the light emitting spot 38. However, the light emitting unit for displaying the light emitting spot can be omitted.

  In the description of the display movement mode in the above embodiment, the case where the accelerometer 31a is moved has been shown, but the display moved in the display movement mode is not limited to the accelerometer. Information displays such as shift indicators, speedometers, and fuel gauges are movable. Further, the movement of the information display is not limited to the movement from the multi display area to the virtual image display area. It is also possible to move the information display from the virtual image display area to the multi display area. In this case, the movement direction of the light emission spot corresponds to the movement direction of the information display, and is a downward direction DD from the virtual image display area to the multi display area.

  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 function of “display control means” may be provided by linking a control unit provided in each of the combination meter and the HUD. Furthermore, the above-described function for controlling the display of each display area 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 for vehicles which mounted in the vehicle and combined the combination meter, HUD, etc. was demonstrated. However, the present invention can also be applied to a display device for a vehicle constituted only by a HUD.
