[Display]
The display section 16 includes a main display section (first display section) 61 that displays an image based on an image signal, and a display section around the main display section 61 that displays an image based on an image signal different from the image signal for the main display section 61. The transparent display panel 62 includes a second display section that performs. At least the display portion of the transparent display panel 62 is configured of a transparent panel through which light can pass from the back side to the front side. That is, the transparent display panel 62 is a so-called see-through type display section through which the background can be seen. The transparent display panel 62 of this embodiment is provided on the front side of the main display section 61, and has a first area 601 that transmits the display image of the main display section 61 and a second area that transmits light from the back side to the front side of the second display section. It has a second region 602 that is transparent. On the other hand, the main display section 61 is a display section whose back side is shielded from light so that the background cannot be seen through.

FIG. 5A is a schematic cross-sectional view showing the configuration of the main display section 61 and the transparent display panel 62. The transparent display panel 62 includes a front protection plate 161, a touch panel 162, a display layer 163, and a back protection plate 164. The front side protection plate 161 and the back side protection plate 164 are members that have high rigidity, maintain the shape of the transparent display panel 160, and protect the touch panel 162 and the display layer 163. In the transparent display panel 62, the higher the transparency of the front side protection plate 161, the touch panel 162, the display layer 163, and the back side protection plate 164, the better, but the transparency is not necessarily limited to the maximum. For example, if the transparency of the material is 100%, even if the front protection plate 161, touch panel 162, display layer 163, and back protection plate 164 are formed with less than 100% transparency due to surface treatment, coloring, etc. good.

The touch panel 162 is, for example, a capacitive sensor that detects, as operation information, a change in capacitance when a user performs a touch operation. The sensor for detecting the operation information is not limited to this, and may be a sensor of another type, such as a resistance type or an infrared type.

The display layer 163 is a self-luminous display element such as an OLED (Organic Light Emitting Diode), in which pixels are arranged in a matrix, and each pixel displays an image. The display layer 163 is not limited to this, and may be a non-self-luminous display element such as a liquid crystal display element. In this case, the back of the main display section 61 may be provided with a backlight. The display layer 163 in FIG. 5A is an example of a second display section.

The main display section 61 includes a touch panel 166, a display layer 167, and a light shielding layer 168. The touch panel 166 and the display layer 167 are the same as the touch panel 162 and the display layer 163 described above, so a repeated explanation will be omitted. The light shielding layer 168 allows the user to use the display layer 167
This is a non-transparent member that blocks light on the back side so that the background cannot be seen through when viewing the displayed image.

In the example of FIG. 5A, the main display section 61 and the transparent display panel 62 are formed separately, but the present invention is not limited to this, and the main display section 61 and the transparent display panel 62 may be formed integrally. FIG. 5B is a diagram showing a display section 16 in which a main display section 61A and a transparent display panel 62A are integrally formed. As shown in FIG. 5B, the transparent display panel 62A includes a front protection plate 161, a touch panel 162, a display layer 163, a back protection plate 164, and a light shielding layer 168. Among these touch panel 162, display layer 163, and back side protection plate 164, a portion provided with light shielding layer 168 on the back side is main display section 61A. Further, of the front side protection plate 161, a portion located in front of the main display portion 61A is a first region 601, and a portion located outside the first region 601 is a second region 602. A light-shielding layer 168 is provided on the back side of the back side protection plate 164 that constitutes the main display section 61A, and a housing 19 is attached to the back side of the main display section 61A. is held in the casing 19.

In the display layer 163, each pixel is capable of emitting light in a plurality of primary colors such as RGB, and the luminance of these primary colors is changed in a plurality of levels (gradations) and combined to perform multicolor display including white. Moreover, the display layer 163 may be provided in multiple layers. FIG. 6 is a diagram showing an example including two display layers 163 and 165. In FIG. 6, in addition to the configuration of FIG. 5B, a second display layer 165 is provided on the back surface of the first display layer 163. The second display layer 165 may be, for example, a liquid crystal display element that changes in multiple stages from a transparent state to a black state for each pixel. That is, the first display layer 163 displays RGB, and the second display layer 165 displays black. Note that the second display layer 165 may, for example, set pixels at the same location as the pixels that perform display on the first display layer 163 to a black state, thereby shielding that location from light. In this case, the background cannot be seen through the portion of the first display layer 163 where the display is performed, and the display is no longer transparent. That is, the second area 602 of the transparent display panel 62 only needs to be transparent at a location where no display is being performed or at a time when no display is being performed, and it is not necessary to be transparent at a location where a display is being performed.

Note that the display layer 163 is not limited to a matrix display element, but may be a segment type display element that displays segments of a specific shape. For example, a configuration may be adopted in which a light-emitting segment is provided in the shape of a soft SW and the segment is turned on or off. Alternatively, the configuration may be such that characters or the state of the software SW are expressed by a combination of segments.

Further, in this embodiment, the main display section 61 and the transparent display panel 62 are formed integrally, but the present invention is not limited to this, and the main display section 61 and the transparent display panel 62 may be formed separately, may be arranged on the front side of the housing 19, and a transparent display panel 62 may be attached around this.

As shown in FIG. 3, when the display section 16 is viewed from the front, an upper display area 621 of the transparent display panel 62 is arranged above the main display section 61. Further, a lower display area 622 of the transparent display panel 62 is arranged below the main display part 61, and side display areas 623 of the transparent display panel 62 are arranged on the sides (left and right) of the main display part 61. . As described above, in this embodiment, the transparent display panel 62 is provided so as to protrude above, below, left and right of the main display section 61. In the case of a general display section, if the display area is increased, the feeling of pressure increases accordingly, but since the outer part of the display section 16 of this embodiment is transparent, the display can be displayed while suppressing the feeling of pressure. Can take up a large area. In particular, in the case of a general display, it cannot be placed above the dashboard 11 because the background becomes invisible, but the transparent display panel 62 is placed above the dashboard 11 because it does not block the driver's view. can be done.

Further, as shown in FIG. 4, the display section 16 has a transverse section 64 extending from the upper edge of the main display section 61 toward the rear side of the display section 16, that is, toward the front of the vehicle 1. An upper display area 621 is erected diagonally upward on the edge. That is, the display section 16 has an S-shaped bent shape when viewed from the side. In this way, the upper display area 621 of the transparent display panel 62 is arranged above the main display section 61 and spaced apart from the display surface 611 of the main display section 61 by a predetermined distance LA on the back side. Further, as shown in FIG. 3, the upper display area 621 of the transparent display panel 62 is spaced upward from the dashboard 11, and is arranged on the same line LA as the height of at least a part of the display area 51 in the HUD 50, The user (driver) can check the display information on the HUD 50 and the display information on the upper display area 621 together. Note that the upper display area 621 may extend straight upward from the main display part 61, but by protruding toward the back side (vehicle front side) via the transverse part 64 as shown in FIG. It is arranged within the driver's forward field of vision, so that the displayed information in the upper display area 621 can be easily recognized when driving.

As shown in FIG. 4, the side display area 623 of the transparent display panel 62 is spaced a predetermined distance LB from the vehicle interior surface (mounting surface) 112 of the dashboard 11 and is provided along the vehicle interior surface 112. ing. Further, the lower display area 622 of the transparent display panel 62 is provided below the dashboard 11 and is arranged at a position that does not overlap with the dashboard 11 when viewed from the user. In this way, the side display area 623 and the lower display area 622 of the transparent display panel 62 are placed apart from the dashboard 11, and the displayed information appears to be floating, giving a novel impression.

The information displayed by the side display area 623 and the lower display area 622 is not particularly limited, but may include, for example, software SW for operating the functions of the CID device 10 or software SW for operating the vehicle equipment 30. You can. The display unit 16 also includes a touch panel (detection unit) 162, and can detect a user's touch operation on the display unit 16. Therefore, for example, when a soft SW is displayed on the transparent display panel 62 and a user performs a touch operation on the software SW, the touch panel 162 detects this operation, and the control unit 12 controls the function of the CID device 10. and controls functions of vehicle equipment 30. As a result, operations for the CID device 10 and the vehicle equipment 30 can be concentrated on the transparent display panel 62, and operations can be performed with a unified operation such as touching the transparent display panel 62, so that usability can be improved. Furthermore, by displaying the soft SW on the transparent display panel 62, even when a large number of soft SW are provided, there are many transparent parts, and the feeling of pressure can be suppressed.

As described above, in this embodiment, since the transparent display panel 62 is extended around the main display section 61, even if the display area is enlarged, the transparent display panel 62 located near the outer edge is transparent, so It looks smaller and reduces the feeling of pressure.

<Second embodiment>
FIG. 7 is a diagram showing the configuration of an information display system 200 according to the second embodiment, and FIG. 8 is a diagram showing the configuration of the CID device 10A according to the second embodiment. This embodiment is different from the first embodiment described above in that a warning is displayed when an object left in the storage section is detected, and the other configurations are the same. For this reason, the same elements as in the first embodiment are given the same reference numerals and will not be described again.

In addition to the configuration of the information display system 100 described above, the information display system 200 of this embodiment includes a storage tray 80 at the top of the center console. The storage tray 80 is provided at a spaced apart position below the second display section, and is one form of a storage section in the present disclosure. The storage tray 80 has a peripheral wall 82 erected on the outer edge of a bottom plate 81, and a storage space 83 recessed from the upper surface to the lower side. The storage space 83 is a space in which items such as a smartphone and a wallet can be stored, for example. In this embodiment, storing the object in the storage tray 80 is not limited to completely storing the object in the storage space 83, but also placing at least a part of the object in the storage space 83, such as placing the object on the bottom plate. Positioning is also called storage.

The CID device 10A includes an object detection section 21 that detects objects stored in the storage tray 80. The object detection unit 21 emits an infrared signal toward the storage tray 80, receives the signal reflected by the object, and detects the presence or absence of the object based on the reflected signal. For example, if there is an object on the storage tray 80, the intensity of the received reflected signal will be higher (the amount of light received will be greater) than when there is no object. Therefore, the object detection unit 21 can detect the presence or absence of an object based on changes in the reflected signal. Note that the object detection unit 21 is not limited to an infrared type, and may be capable of capturing an image of the storage tray 80 and detecting an object on the storage tray 80 through image processing, or using a ToF (Time of Flight) sensor or Other methods of detecting the object, such as detecting the object using a three-dimensional scanner, may be used.

In addition to the configuration shown in FIG. 2, the control unit 12 includes an alighting determination unit 125 that determines whether the user has alighted from the vehicle, a left behind determination unit 126, and a left behind warning unit 127.

The alighting determining unit 125 determines that the user has alighted from the vehicle 1 and has finished using the CID device 10A. For example, the alighting determination unit 125 detects whether the vehicle 1 is powered off by the detection unit 20 when the door is locked after the accessory power is turned off, or when the seat sensor no longer detects the occupant (the occupant stands up). When the detected vehicle information satisfies a predetermined condition, it is determined whether the user gets off the vehicle. Note that the alighting determining unit 125 is not limited to determining whether the user has completely alighted from the vehicle 1, but may determine the state immediately before the user alights from the vehicle. For example, the alighting determination unit 125 may determine that the user is about to alight from the vehicle when a predetermined period of time has passed since the accessory power source was turned off or when the door has been opened.

The lost item determination unit 126 determines whether or not an item is left behind in the storage tray 80 . For example, if there is an item in the storage tray 80 at the time when the alighting determination unit 125 determines that the user has alighted from the vehicle, the left behind item determination unit 126 determines that the item is a left behind item. Note that if the number of items has increased compared to when the user got off the vehicle last time, the lost item determination unit 126 may determine that the item is a forgotten item. In other words, items that have been left behind since the last time the user got off the vehicle do not need to be determined as left behind items. In addition, the lost item determination unit 126 attempts to connect with the user's smartphone via the communication IF 15 using NFC (Near field communication) or Bluetooth (registered trademark) with the communication range limited to the vicinity of the storage tray, and when the user gets off the vehicle, If the connection is possible, it is determined that there is something left behind (smartphone). In this case, the communication IF 15 functions as the object detection section 21.

When the forgotten item determination unit 126 determines that there is an item left behind, the lost item warning unit 127 indicates that there is an item left behind on the display unit 16, that is, the first display unit (main display unit 61) or the second display unit (transparent display panel 62). A warning display will be displayed to indicate this. For example, blinking the upper display area 621, displaying a message such as "I forgot something", displaying an arrow moving from top to bottom in the side display area 623 and the lower display area 622, etc. By displaying a specific display, the user is warned that they have forgotten something. Note that specific displays such as flashing displays, message displays, and moving arrow displays may be performed in all of the display area (upper, side, and lower) of the second display section, or may be performed in only a portion of the display area (upper, side, and lower). Also good. In this way, the CID device 10 of this example displays a specific display in the lower display area 622 near the storage tray 80, thereby reminding the user of having left something there, and making the user aware of forgotten items. It can be made easier.

Note that, when the CID device 10A detects a forgotten item and displays a warning after the accessory power is turned off, the CID device 10A may include a built-in battery for performing these operations. Also, C
The ID device 10A may be connected to the battery of the vehicle 1 so that it can receive power even when the accessory power source is OFF.

FIG. 9 is a diagram showing a flow of a display method executed by the control unit 12 of the CID device 10A. When the accessory power source of the vehicle 1 is turned on and power is supplied to the CID device 10A, the control unit 12 starts the process shown in FIG. 9 . Further, the control unit 12 periodically executes the process shown in FIG. 9 until the power supply is stopped.

In step S10, the control unit 12 acquires vehicle information of the vehicle 1 from the detection unit 20 or the ECU 40.

In step S20, the control unit 12 determines whether the user has gotten off the vehicle 1 or is about to get off the vehicle (these states are also referred to as an alighting state), that is, whether the use of the CID device 10A has ended. Determine whether For example, the alighting determination unit 125 determines that the user has alighted (affirmative determination) when the door of the vehicle 1 is locked after the accessory power source of the vehicle 1 is turned off. If the control unit 12 makes a negative determination in step S20, it ends the process of FIG. 9, and if it makes an affirmative determination in step S20, it proceeds to step S30.

In step S30, the control unit 12 determines whether there is anything left behind based on the detection result of the object detection unit 21. If the control unit 12 makes a negative determination in step S30, it ends the process of FIG. 9, and if it makes an affirmative determination in step S30, it moves to step S40.

In step S40, the control unit 12 causes the display unit 16 to display a warning indicating that something has been left behind. Furthermore, along with the warning display, a warning sound or a voice message may be output from the speaker. In this way, when displaying a warning on the transparent display panel 62, since the transparent display panel 62 is located at the outer edge of the display section 16, it is easily visible to the user who has gotten off the vehicle or the user who is about to get off the vehicle. can remind you of forgotten items.

In this manner, the CID device 10A of the present embodiment determines that an item such as a smartphone is left behind in the storage tray 80 when use is finished, and displays a warning on the display unit 16. This gives a warning to the user and prevents him/her from leaving behind his or her smartphone, wallet, etc.

<Modified example>
FIG. 10 is a diagram showing a CID device 10B according to a modified example. In the second embodiment described above, the information display system 200 was configured to include a storage tray (storage section) 80 configured separately from the CID device 10A, but in this modification, the CID device 10B has a storage tray (storage section) 80 configured separately from the CID device 10A. This is a configuration that is equipped with. Note that since the other configurations are the same as those of the first embodiment described above, the same elements are given the same reference numerals, and a repeated explanation will be omitted.

As shown in FIG. 10, in the CID device 10B, a storage tray (storage section) 180 is provided at the lower front side of the housing 19 via a stay 182 extending downward. That is, the storage tray 180 is arranged below the transparent display panel 62.

When the storage tray 180 is disposed below the display section 16 in this manner, in the case of a conventional display section, the stored items are likely to be hidden behind the display section and left behind. In contrast, in this modification, the transparent display panel 62 is transparent and the items stored in the storage tray 180 are not hidden, so it is possible to prevent items from being left behind. Note that in this modification, the configuration other than the storage tray 180 is the same as the first embodiment, but the configuration is not limited to this. It is also possible to have a configuration in which this is done.

Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited thereto. Various modifications are possible.
