The display device 100 in FIG. 2 includes a control unit 102, a storage unit 104, a communication IF (Interface) 106, a display The display device 100 includes a display element 120 and a touch panel 130. The control unit 102, the storage unit 104, the communication IF 106, the display element 120 and the touch panel 130 are connected to one another via a bus. The display device 100 can be realized, for example, by a device equipped with a computer.

[0012] The display device 100 may be communicably connected to an in-vehicle device having, for example, a navigation function for guiding a route to a destination of the vehicle, a drive recording function for recording an image captured by the vehicle on a recording medium, and a playback function for playing audio data and video data. The display device 100 may also be communicably connected to an in-vehicle device having, for example, a function for receiving a television broadcast wave or a radio broadcast wave and outputting an image or sound from the received broadcast wave, and an air conditioner adjustment function for adjusting an air conditioner (air conditioner) of the vehicle. The display device 100 may also be communicably connected to an in-vehicle device having various other functions. The display device 100 may have the functions of the in-vehicle device. The display device 100 may also be included in the in-vehicle device.

[0013] The display device 100 displays predetermined information on the display element 120 (for example, information related to the navigation function, information related to the playback function, information related to the air conditioning function, etc.), and receives input from a user such as a driver via the touch panel .

[0014] The control unit 102 is a central processing unit that controls the entire display device 100. The control unit 102 is also called a processor. The control unit 102 is not limited to a single processor, and may have a multi-processor configuration. Also, a single control unit 102 connected by a single socket may have a multi-core configuration. The control unit 102 deploys programs stored in the storage unit 104 in an executable manner in a work area, and provides functions that meet a predetermined purpose by controlling peripheral devices and the like through the execution of the programs. The control unit 102 may include a dedicated LSI (Large Scale Integration) such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field-Programmable Gate Array), or other digital circuits. good.

[0015] The memory unit 104 stores the programs and data used by the control unit 102 and expands the working area. The storage unit 104 is a recording medium that stores operation setting information and the like. The storage unit 104 is, for example, a flash memory, a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard-disk Drive), or a SSD (Solid State Drive). The storage unit 104 is, for example, an EPROM (Erasable Programmable ROM), a flash memory, a USB memory, a S A Secure Digital (D) memory card, etc. The storage unit 104 can also include a portable recording medium that can be read by a computer, etc., and a drive device or other device that can read and write data, etc. to the recording medium.

[0016] The communication IF 106 is a communication interface that communicates with other information processing devices, such as an in-vehicle device, via a communication network or the like. The communication IF 106 can be connected to other information processing devices so as to be able to wirelessly communicate with them using well-known wireless communication standards, such as wireless LAN and Bluetooth (registered trademark). The communication IF 106 can also be connected to other information processing devices using a standard such as CAN (Controller Area Network), The vehicle may be connected to an in-vehicle network and communicate with other devices installed in the vehicle.

[0017] The display element 120 is a display device that displays images and text information. The display element 120 is, for example, an organic EL (Organic Electroluminescence) panel. The display element 120 is, for example, a CID (Central Information Display) installed in the center of the front of the vehicle. Here, the display element 120 is a type of organic electroluminescence (EL). The display element 120 may be a curved OLED (Organic Light Emitting Diode). The curved OLED is a display that can have a curved display surface. Other displays that can have a curved display surface may be used as the display element 120. The CID mainly displays various information to passengers such as the driver of the vehicle.

[0018] The display element 120 includes, for example, a first region 121 which is a display region protruding from the dashboard 200, and a second region 122 which is a display region embedded in the dashboard 200. The surface of the second region 122 has a curved shape integrated with the surface of the dashboard 200. That is, the surface of the second region 122 has a shape that follows the surface of the dashboard 200. The first region 121 has a substantially flat shape. The first region 121 may have a curved shape at a portion connected to the second region 122. The surface of the second region 122 is covered with a transparent skin 140. The shape of the second region 122 is, for example, the same as a part of the side surface of a cylinder. The first region 121 displays a map in a navigation function, a content being played in a content playback function, information on the temperature inside the vehicle in an air conditioning control function, and the like. The second region 122 displays a GUI (Graphical User Interface) for operating the function. A GUI (operation interface) for operating the function includes images showing, for example, buttons, icons, levers, wheels, and the like.

[0019] The touch panel 130 is an input device provided on the surface (display surface) of the display element 120. The touch panel 130 is, for example, a capacitive touch panel that detects a contact position based on a change in capacitance when a part of the user's body, such as a finger, touches an operation surface. The part of the body is a part such as a finger, a palm, or a back of the hand. The contact is not limited to a direct contact by a part of the user's body, but also includes an indirect contact by a stylus or the like held by the user. The touch panel 130 is not limited to a capacitive type, and may be a touch panel of another type such as an optical type. The touch panel 130 is provided along the display surface of the first region 121 and the second region 122 of the display element 120. The touch panel 130 defines a coordinate system along the display surface of the display element 120, and outputs the contact position as a coordinate in the coordinate system. Each coordinate corresponds to each position on the display surface. Here, the touch panel 130 may be provided at least in the second region 122.

[0020] A transparent skin 140 is attached to the surface of the second region 122 of the display element 120. The material is a semi-transparent film or the like. The transparent skin 140 is printed with a predetermined color or pattern in advance. For example, the transparent skin 140 is printed with a color (black, gray, etc.) or a pattern (wood grain, marble, etc.) similar to the surface of the dashboard 200. The pattern may also be a pattern that imitates the surface of a material such as leather or fabric. When nothing is displayed in the second region 122 of the display element 120, the predetermined color or pattern of the transparent skin 140 is visible from the outside. That is, when nothing is displayed in the second region 122 of the display element 120, the surface of the dashboard 200 and the transparent skin 140 have the same appearance. Also, when some display is displayed in the second region 122 of the display element 120, the user can see the display of the second region 122 through the transparent skin 140 from the outside. That is, the second region 122 can provide a visual effect in which the display of the display element 120 appears on the surface of the transparent skin 140, which looks similar to the surface of the dashboard 200. The color and pattern of the print applied to the transparent skin 140 do not have to be exactly the same as the color and pattern of the surface of the dashboard 200, but may be similar to the color and pattern of the surface of the dashboard 200 to some extent so that the color and pattern are difficult to distinguish from each other. The transparent skin 140 attached to the second region 122 is an example of a surface treatment that transmits light from the display element 120. The surface of the transparent skin 140 has the same unevenness as the surface of the dashboard 200. Specifically, it has the same unevenness as the graining or embossing applied to the surface of the dashboard. The similar unevenness means, for example, that the unevenness pattern is the same as the graining or embossing applied to the surface of the dashboard, or that the height difference of the surface is within the same range. Making the surface of the transparent skin 140 have the same unevenness as the surface of the dashboard 200 is an example of a surface treatment based on the surface of the dashboard 200 for the second region 122. This makes the tactile feel of the transparent skin 140 similar to that of the surface of the dashboard 200. The unevenness of the translucent skin 140 does not have to be exactly the same as the unevenness of the surface of the dashboard 200, as long as it is similar to the unevenness to a certain extent. Furthermore, the first region 121 is not covered by the translucent skin 140. Therefore, the surface of the first region 121 and the surface of the second region 122 have different tactile sensations.That is, the user can recognize whether the area he or she is touching is the first area 121 or the second area 122 without looking at the display element 120. The transparent skin 140 is an example of a surface treatment for the second area 122. Furthermore, by performing a surface treatment with the transparent skin 140 on the second area 122, the difference in appearance between the first area 121 and the second area 122 becomes clear. Here, it is possible to perform an input operation on the touch panel 130 through the transparent skin 140. By performing a surface treatment with the transparent skin 140 on the second area 122, slippage of the user's fingers is suppressed, and the user can easily perform an operation on the touch panel 130 in the second area 122. The second area 122 is flush with the surface of the dashboard 200 due to the transparent skin 140.

[0021] (Example) Here, a display example of the display element 120 of the display device 100 will be described.

[0022] FIG. 3 is a diagram showing Example 1 of a GUI displayed in the second area 122. In FIG. 3, it is assumed that the upper end of the second area 122 is connected to the first area 121. Here, in the second area 122 in FIG. 3, the horizontal direction (from left to right) along the surface of the second area 122 is the x direction, and the vertical direction (from the second area 122 to the first area 121) along the surface of the second area 122 is the y direction. In the second area 122 in FIG. 3, images of a first button 201, a second button 202, a third button 203, and a wheel 210 are displayed. The first button 201, the second button 202, the third button 203, and the wheel 210 are examples of a GUI for performing operations on a map of the navigation function, contents of the playback function, and the like, displayed in the first area 121. The outer frames of the first button 201, the second button 202, and the third button 203 in FIG. 3 are rectangular, but are not limited to rectangular. Each button may include characters or images indicating the contents of the function. Each button may be an image of an icon indicating the content of the function. The first button 201, the second button 202, and the third button 203 are aligned in one direction in the x direction. 10 is an image of the disk as viewed from the side. When the control unit 102 detects contact with each of the first button 201, the second button 202, and the third button 203 by the touch panel 130, the control unit 102 executes a function associated with each button. When the control unit 102 detects an operation of tracing from bottom to top or from top to bottom at the position of the wheel 210, the control unit 102 performs a process of changing the button to be displayed. Here, the surface of the second region 122 has a curved shape that is the same as a part of the surface of a cylinder having a central axis parallel to the x direction, for example. In this case, the surface of the second region 122 is curved along the y direction.

[0023] FIG. 4 is a diagram showing an example 1 of a perspective view of the display element 120. In the second region 122 of FIG. 4, the GUI (first button 201, second button 202, third button 203, wheel 210) shown in FIG. 3 is displayed. Here, the transparent skin 140 is omitted. Since the second region 122 is a curved surface, the first button 201, the second button 202, the third button 203, and the wheel 210 look three-dimensional. For example, the first button 201, the second button 202, and the third button 203 are simply rectangular in FIG. 3, but in FIG. 4, they are three-dimensionally represented as if they were attached to the surface of a virtual cylinder. In addition, in FIG. 4, the wheel 210 is three-dimensionally represented as if a disk was viewed from the side. The control unit 102 may display each button with the vertical lines of the outer frame of each button recessed inward, so that each button looks flat.

[0024] Fig. 5 is a diagram showing Example 2 of a perspective view of the display element 120. In the second region 122 of Fig. 5, a boundary line 231 between the top surface and side surface 233 of a virtual cylinder, and a boundary line 232 between the bottom surface and side surface 233 of the virtual cylinder are displayed. In addition, a GUI (first button 201, second button 202, third button 203, wheel 210) is displayed on the side surface 233 of the virtual cylinder. Here, the transparent skin 140 is omitted. The first button 201, second button 202, third button 203, and wheel 210 are displayed as if they are attached to the side surface 233 of the virtual cylinder.

[0025] Fig. 6 is a diagram showing example 3 of a perspective view of the display element 120. In the second area 122 of Fig. 6, a boundary line 241 between the top surface and side surface 243 of a virtual prism, and a boundary line 242 between the bottom surface and side surface 243 of the virtual prism are displayed. In addition, a GUI (first button 201, second button 202, third button 203, wheel 210) is displayed on the side surface 243 of the virtual prism. Here, the transparent skin 140 is omitted. The first button 201, second button 202, third button 203, and wheel 210 are displayed as if they are attached to the side surface 243 of the virtual prism.

[0026] 7 and 8 are diagrams showing an example of an operation on the wheel 210. In FIG. 7 and FIG. 8, it is assumed that the upper end of the second region 122 is connected to the first region 121. Here, in the second region 122 in FIG. 7 and FIG. 8, the horizontal direction (direction from left to right) along the surface of the second region 122 is the x direction, and the vertical direction (direction from the second region 122 to the first region 121) along the surface of the second region 122 is the y direction. In the second region 122 in FIG. 7, images of the first button 201, the second button 202, the third button 203, the fourth button 204, the fifth button 205, the sixth button 206, and the wheel 210 are displayed. In the second region 122 in FIG. 8, images of the fourth button 204, the fifth button 205, the sixth button 206, and the wheel 210 are displayed. The fourth button 204, the fifth button 205, and the sixth button 206, like the first button 201, are examples of GUIs for operating the map of the navigation function, the content of the playback function, and the like, displayed in the first area 121.

[0027] When the control unit 102 detects a downward-to-upward tracing operation with the finger of the user's hand 300 on the position of the image of the wheel 210 through the touch panel 130, the control unit 102 moves the first button 201, the second button 202, and the third button 203 upward in accordance with the tracing operation. The tracing operation becomes an operation similar to rotating a wheel for the user because the second area 122 is curved. The user can feel as if he or she is actually rotating a wheel because the second area 122 is curved. The control unit 102 does not display the parts of the first button 201, the second button 202, and the third button 203 that protrude from the second area 122. In addition, the control unit 102 displays the fourth button 204, the fifth button 205, and the sixth button 206 from the bottom and moves them upward in accordance with the tracing operation. Furthermore, when the tracing operation is continued, as shown in FIG. 8, the control unit 102 erases the first button 201, the second button 202, and the third button 203, and displays the entire fourth button 204, the fifth button 205, and the sixth button 206. As a result, the GUI for operation is switched from the first button 201, the second button 202, and the third button 203 to the fourth button 204, the fifth button 205, and the sixth button 206. At this time, since the surface of the second area 122 has the same curved shape as a part of the surface of a cylinder having a central axis parallel to the x direction, each button appears to rotate around the central axis of the cylinder to which the button is attached as the axis of rotation. In other words, each button appears to move and switch in a direction perpendicular to the direction of the central axis of the cylinder. Similarly, when the control unit 102 detects a tracing operation from top to bottom on the position of the image of the wheel 210 by the touch panel 130, the first button 201, etc. is moved downward and another button is displayed from above.

[0028] FIG. 9 is a diagram showing a second example of a GUI displayed in the second area 122. In FIG. 9, it is assumed that the upper end of the second area 122 is connected to the first area 121. Here, in the second area 122 in FIG. 9, the horizontal direction (from left to right) along the surface of the second area 122 is the x direction, and the vertical direction (from the second area 122 to the first area 121) along the surface of the second area 122 is the y direction. In the second area 122 in FIG. 9, images of a first button 201, a second button 202, a third button 203, and a lever 220 are displayed. The first button 201, the second button 202, the third button 203, and the lever 220 are examples of a GUI for performing operations on a map of the navigation function, contents of the playback function, and the like, displayed in the first area 121. Each button may include characters or images indicating the contents of the function. The first button 201, the second button 202, and the third button 203 are the same as the buttons in FIG. 3. When the control unit 102 detects a tracing operation from bottom to top or from top to bottom at the position of the lever 220, the control unit 102 performs a process of changing the buttons to be displayed. When the control unit 102 detects a tracing operation from bottom to top by the user at the position of the image of the lever 220 by the touch panel 130, the control unit 102 moves the first button 201, the second button 202, and the third button 203 upward as in FIG. 7. The control unit 102 does not display the parts of the first button 201, the second button 202, and the third button 203 that protrude from the second area 122. Furthermore, as in FIG. 7, the control unit 102 displays the fourth button 204, the fifth button 205, and the sixth button 206 from the bottom and moves them upward. Finally, as in FIG. 8, the control unit 102 erases the first button 201, the second button 202, and the third button 203, and displays the fourth button 204, the fifth button 205, and the sixth button 206. As a result, the GUI for performing operations is switched from the first button 201, the second button 202, and the third button 203 to the fourth button 204, the fifth button 205, and the sixth button 206.

[0029] The translucent skin 140 at the position of the wheel 210 or the position of the lever 220 may be processed differently from the translucent skin 140 around that position. For example, the position of the wheel 210 or the position of the lever 220 may be processed to have larger projections and recesses than the surrounding area. Also, the translucent skin 140 at the position of the wheel 210 or the position of the lever 220 may be given a shape or surface treatment that simulates the tactile feel of a wheel or lever. By having the translucent skin 140 at the position of the wheel 210 or the position of the lever 220 have a different tactile feel from the surrounding translucent skin 140, the user can easily recognize the position of the wheel 210 or the lever 220.

[0030] The control unit 102 may make the difference between the first area 121 and the second area 122 clear by making the font of the characters displayed in the first area 121 different from the font of the characters displayed in the second area 122. The control unit 102 may make the difference between the first area 121 and the second area 122 clear by making the color tone of the image displayed in the first area 121 different from the color tone of the image displayed in the second area 122 (for example, full color and monotone, cool colors and warm colors). By making the difference between the first area 121 and the second area 122 clear, the user can easily find the GUI for the desired operation.

[0031] (Actions and Effects of the Embodiments) The display system 10 of the present embodiment includes a display device 100 including a display element 120 having a first region 121 protruding from a dashboard 200 and a second region 122 including a curved surface integrated with the dashboard 200. A touch panel 130 is provided on the display element 120. A surface treatment using a transparent skin 140 is applied to the surface of the second region 122 of the display element 120. The first region 121 displays information related to functions such as a map in a navigation function and contents in a content playback function, and the second region 122 displays a GUI for operating each function. By displaying the GUI for operation in the second region 122, the time required to find a target operation button or the like is shortened, and the time required to complete the operation can be shortened. By changing the surface texture between the first region 121 and the second region 122, it is possible to suppress erroneous pressing.
