Description

display device

[0001] The present invention relates to a display device mounted on a vehicle.

[0002] Conventionally, display devices that display various content information related to a vehicle have been known. Examples of content information include vehicle speed information, output information, location information, navigation information, audio information, application information, and the current time. Display devices have been proposed for recent vehicles that have large display screens, provide users with a wealth of information, and offer improved operability and visibility. For example, Patent Document 1 (JP-A-2005-102226) discloses a display control device that can provide excellent operability by enabling a first screen and a second screen to be swapped on a display screen that is enlarged in the horizontal direction.

[0003] Japanese Patent Application Laid-Open No. 2022-093356

[0004] The display control device disclosed in Patent Document 1 allows two screens to be swapped horizontally to display information and accept user operations on each screen, but only two types of information can be displayed and the display size cannot be changed. Therefore, there is room for improvement in order to achieve a good user experience (emotions, impressions, and reactions experienced by users through operation inputs to and outputs from the display device). For example, there is a need for a display device that can meet a wide range of user needs, such as a need to display only one piece of information enlarged or a need to view multiple pieces of information simultaneously.

[0005] The present invention was conceived in consideration of these problems, and one of its objectives is to provide a display device that can improve the user experience. However, in addition to this objective, another objective of the present invention is to achieve effects derived from the configurations shown in the "Mode for Carrying Out the Invention" described below, which are effects that cannot be obtained with conventional technologies.

Aspect 3. In Aspect 2 above, it is preferable that the display enlargement operation includes a touch operation on the first area.

[0009] Aspect 4. In any of Aspects 1 to 3 above, it is preferable that a screen transition from the third display mode to the second display mode and from the second display mode to the first display mode occur in response to a display reduction operation by the user. Aspect 5. In Aspect 4, which cites Aspects 2 or 3 above, it is preferable that the display reduction operation includes a pressing operation on a physical button provided separately from a screen on which the content display unit is displayed.

[0010] Aspect 6. In Aspect 4 or 5 above, it is preferable that the display reduction operation when transitioning the screen from the second display mode to the first display mode includes a swipe operation of the content display section that is enlarged and displayed at an edge of the screen in the second display mode or the content display section that is located on the same screen, toward the edge.

[0011] Aspect 7. In any of Aspects 1 to 6 above, it is preferable that in the first display mode, three of the content display units are displayed side by side in a horizontal row, that in the second display mode, one of the content display units is enlarged to approximately twice the size of the content display unit displayed in the first display mode and another content display unit of the same size as the content display unit displayed in the first display mode are displayed side by side, and that in the third display mode, only the one content display unit is displayed.

[0012] The disclosed display device can meet various user needs and improve the user experience.

[0013] 1 is a block diagram illustrating a configuration of a display device according to an embodiment. (a) to (d) are diagrams illustrating examples of screen configurations in three display modes. (a) to (c) are diagrams illustrating specific examples of content display sections displayed in the three display modes. (a) to (c) are diagrams illustrating specific examples of the three display modes.

[0014] A display device according to an embodiment will be described with reference to the drawings. The embodiments described below are merely examples, and are not intended to exclude various modifications or applications of techniques not explicitly described in the following embodiments. The configurations of the embodiments can be modified in various ways without departing from the spirit of the embodiments. Furthermore, they can be selected or combined as needed.

[0015] [1. Configuration] Fig. 1 is a block diagram showing the configuration of a display device 1 according to an embodiment. The display device 1 is mounted on a vehicle (not shown) and displays various content information related to the vehicle. The content information is mainly information representing the vehicle's driving state and the operating state of on-board equipment. Specific examples of content information representing the vehicle's driving state include speed, shift position, transmission reduction ratio, name of driving mode, driving distance, estimated remaining driving distance, fuel economy, electricity consumption, remaining battery capacity, yaw rate, roll rate, pitch rate, longitudinal acceleration, lateral acceleration, road surface inclination angle, tire pressure, powertrain energy flow, driving direction (orientation), altitude, temperature, and road surface friction coefficient.

[0016] Furthermore, content information indicating the operating status of in-vehicle devices may include audio information, car navigation information, lighting status information, cruise control-related information, following distance information, and air conditioning information. The display device 1 may also be connected to a user's smartphone and display content information indicating the operating status of the smartphone (e.g., call information, email sending / receiving information, etc.). This information is generated or acquired by, for example, various ECUs, various in-vehicle devices, various sensors, etc., and transmitted to the display device 1. The content information may also include vehicle speed information, output information, etc.

[0017] As shown in Fig. 1, the display device 1 includes an electronic control device 2 and an output device 3. The electronic control device 2 is a computer for controlling the content displayed on the output device 3, and includes a processor (arithmetic processing unit) and a memory (storage device). The processing content (program) of the electronic control device 2 is stored in the memory, and is executed by loading the content into the processor as appropriate. The electronic control device 2 may be formed integrally with the output device 3 (built into the output device 3), or may be provided separately from the output device 3.

[0018] The output device 3 is a device that displays the above-mentioned information about the vehicle, and is, for example, a liquid crystal display, an organic electroluminescence (EL) display, a projector, etc. Hereinafter, the display or projector screen on which information is displayed will also be referred to as a display screen 10 (see FIG. 2(a), etc.). All information displayed on the display screen 10 is controlled by the electronic control unit 2. The shape of the display screen 10 (the shape of the area in which information is displayed) is not particularly limited, but is, for example, rectangular.

[0019] The output device 3 is disposed in a position that is easily visible to the driver, such as in the front center of the vehicle cabin (forward between the driver's seat and the passenger seat) or in front of the driver (forward of the steering wheel). An input device that accepts input operations for the content of the display screen 10 may be provided as an auxiliary device of the output device 3. Specific examples of the input device include a touch panel device that detects touch operations on the display screen 10, an input device provided with a keyboard, physical buttons, or a touchpad, a gaze detection device that detects gaze, and a gesture reading device that detects gesture operations.

[0020] [2. Details of Display Modes] [2-1. Display Modes] The display device 1 has at least three display modes (first display mode 4, second display mode 5, and third display mode 6) as display modes (display forms) of information displayed on the output device 3. These display modes 4, 5, and 6 are switched by a user's display enlargement operation or display reduction operation, which will be described later.

[0021] As shown in FIG. 2( a), first display mode 4 is a mode in which multiple content display sections 7 (7A-7D) displaying the above-mentioned content information are displayed side by side on the same screen. The content (content information) displayed on each content display section 7 is different. All of the multiple content display sections 7 displayed in first display mode 4 have the same screen size (size of the display area). Hereinafter, the screen size of the content display section 7 in first display mode 4 is referred to as the "first size 11." The first size 11 is, for example, rectangular, and its aspect ratio is not particularly limited. Note that, as shown in FIG. 2( a), depending on the relationship between the size of the display screen 10 and the first size 11, the screen size 11' of the content display section 7D located at the edge of the display screen 10 may be an intermediate size smaller than the first size 11. Alternatively, to prevent an intermediate screen size 11' from being displayed, the first size 11 may be set to a size obtained by dividing the size of the display screen 10 into multiple equal parts.

[0022] In the first display mode 4, the display device 1 may change the displayed content display portion 7 by scrolling (for example, swiping left or right) the content on the display screen 10. For example, by scrolling the content on the display screen 10 shown in FIG. 2A leftward, the content display portion 7A on the left edge may become an incomplete screen size 11′ or disappear, and instead, the content display portion 7D on the right edge or a content display portion 7 on the right side thereof may be displayed.

[0023] The display device 1 may have non-display content display sections 7 in addition to the content display sections 7 displayed on the display screen 10, and all of the content display sections 7, including the non-display content display sections 7, may be arranged in a horizontal row, for example. In this case, the order of the content display sections 7 may be changeable by a user operation, but it is preferable that it cannot be changed without a user operation. In the first display mode 4, the user can check all content information and select the content information they want to view.

[0024] 2(b) and 2(c) is a mode in which one of the multiple content display sections 7 selected by the user is enlarged to cover the area of ​​the content display section 7 that was adjacent to that one content display section 7 in first display mode 4, and a portion of the content display section 7 that was displayed in first display mode 4 is displayed alongside the enlarged content display section 7 on the same screen. Hereinafter, the screen size of the content display section 7 enlarged and displayed in second display mode 5 will be referred to as the "second size 12." The second size 12 is approximately twice the size of the first size 11.

[0025] In the example shown in FIG. 2(b), content display section 7A is enlarged to cover the area of ​​content display section 7B in FIG. 2(a), and portions of content display section 7B and content display section 7C are also displayed. That is, in FIG. 2(b), the "one content display section 7" is content display section 7A, and the "portion of content display section 7" is content display section 7B and portions of content display section 7C. Thus, when a content display section 7 selected by a user is located at the edge of the display screen 10 (here, the left edge), the content display section 7 is enlarged to approximately twice its original size toward the opposite side of the edge (here, the right edge). Furthermore, the order of the content display sections 7 remains unchanged even when enlarged. For example, when content display section 7A is enlarged to cover the area of ​​content display section 7B, content display section 7B is shifted accordingly, or is hidden as a result of the shift.

[0026] 2(c), content display section 7B is expanded to cover the area of ​​content display section 7C in FIG. 2(a), and the remaining content display sections 7A and 7C are also displayed. That is, in FIG. 2(c), the "one content display section 7" is content display section 7B, and the "part of the content display section 7" is content display section 7A and part of content display section 7C. In this way, when the content display section 7 selected by the user is not located at the edge of the display screen 10, the content display section 7 may be expanded in either the left or right direction.

[0027] The content display sections 7 that can be selected by the user may be limited to those displayed in the first size 11. For example, the content display section 7D shown in FIG. 2(a) cannot be selected. In this case, the content display section 7C in FIG. 2(a) is included in the content display sections 7 located at the "edge of the display screen 10." In other words, when the content display section 7C is selected in the first display mode 4 in FIG. 2(a), the content display section 7C is enlarged to approximately twice its original size toward the opposite side from the edge (i.e., the left side). As a result, the content display section 7B in the first size 11, the content display section 7C in the second size 12, and the content display section 7D in the incomplete screen size 11' are displayed on the display screen 10 in this order from left to right. Note that if the user wants to enlarge the content display section 7D in the incomplete screen size 11', they can simply perform a swipe operation in the first display mode 4 and select it after the content display section 7D is displayed in the first size 11.

[0028] Furthermore, the user can select the content display portion 7 in the first size 11 in the first display mode 4, but can also select the content display portion 7 in the first size 11 in the second display mode 5. In the latter case, the mode itself, second display mode 5, does not change, but the content display portion 7 displayed in the second size 12 changes. For example, when the content display portion 7B is selected in the second display mode 5 shown in FIG. 2(b), the screen switches to the screen of the second display mode 5 shown in FIG. 2(c). In the second display mode 5, the user can view multiple pieces of content information while enlarging the content information that the user primarily wants to check.

[0029] The third display mode 6 shown in FIG. 2(d) is a mode in which the content display portion 7, which was enlarged in the second display mode 5, is displayed full screen. Hereinafter, the screen size of the content display portion 7 displayed full screen in the third display mode 6 will be referred to as the "full screen size 13." The full screen size 13 is approximately the same as the size of the display screen 10. In the example shown in FIG. 2(d), the content display portion 7A, which was displayed in the second size 12 in FIG. 2(b), is displayed full screen. In the third display mode 6, the user can view only one piece of content information on a large screen.

[0030] [2-2. Display Enlargement Operation] In response to a display enlargement operation by the user, the display device 1 transitions from the first display mode 4 to the second display mode 5, and transitions from the second display mode 5 to the third display mode 6. The display enlargement operation is a predetermined operation set according to the output device 3 (or an accessory device of the output device 3). For example, if a touch panel device is attached, a touch operation or a swipe operation on an image or screen is set as the display enlargement operation. Furthermore, if an input device is attached, a click operation or a press operation on a keyboard, physical button, or touchpad can be set as the display enlargement operation. Only one display enlargement operation may be set, or multiple display enlargement operations may be set.

[0031] 3(a) to 3(c) show specific examples of content display sections 7 having a first size 11, a second size 12, and a full-screen size 13, which are displayed in three display modes 4, 5, and 6, respectively. Each content display section 7 has a first area 21 that displays the title of the content information and a second area 22 that displays the content of the content information. The first area 21 is also called a header. In addition to displaying the content of the content information, the second area 22 may also have a function of accepting user operations (such as touch operations and swipe operations).

[0032] In the display device 1 of this embodiment, the above-described display enlargement operation includes a touch operation on the first area 21. That is, the first area 21 has a function of receiving touch operations in addition to a title display function. Also, as shown in FIGS. 3( a) to 3(c), the amount of information in the second area 22 increases as the screen transitions according to the display enlargement operation. Here, "increasing the amount of information" does not simply mean that characters, images, etc. are enlarged, but also means that the type, number, and amount of displayed information increase.

[0033] For example, the content display section 7 shown in FIGS. 3( a) to 3(c) displays audio information. In the content display section 7 in the first size 11 (first display mode 4) of FIG. 3(a), the second area 22 displays the song title, jacket image, seek bar, play / stop icon, rewind icon, fast-forward icon, and other icons. When the content display section 7 is enlarged to the second size 12 shown in FIG. 3(b), the second area 22 further displays the playback time, multiple icons such as a shuffle icon, and a repeat icon. In addition to songs, icons for selecting radio or Bluetooth® connection may also be displayed. In this way, the amount of information displayed increases by expanding the screen from the first size 11 to the second size 12, providing the user with more information. In the full-screen size 13 shown in FIG. 3(c), the types and number of information remain the same as in the second size 12, but additional information may be added from the second size 12.

[0034] Specific examples of the first display mode 4, the second display mode 5, and the third display mode 6 are shown in FIGS. 4A to 4C. In this example, as shown in FIG. 4A, in the first display mode 4, three content display sections 7A, 7B, and 7C of the first size 11 are displayed in a horizontal row. The content display section 7A displays the audio information shown in FIG. 3A, the content display section 7B displays the call information, and the content display section 7C displays the content information in a meter display using, for example, letters, numbers, scales, images, etc. In this example, a launcher display area 8 in which a launcher for launching an application is displayed is provided within the display screen 10, and an operation section 30 with an array of physical buttons 31 to 35 that can be operated by the user is provided separately from the display screen 10 (outside the display screen 10).

[0035] In this example, the launcher display area 8 is provided vertically on each of the left and right sides of the display screen 10, but the layout and shape of the launcher display area 8 are not limited to this. Examples of applications launched by the launcher include a video recording app, a navigation app, and a settings app. Note that icons indicating the time, the signal strength of the linked smartphone, the remaining battery level, the email reception status, etc. may be displayed in the four corners (e.g., the upper right and upper left) of the display screen 10.

[0036] The operation unit 30 is provided, for example, below the display screen 10. The operation unit 30 has a home button 31 in the center in the horizontal direction, a call button 32 and an audio button 33 on either side of the home button 31, volume buttons 34N and 34P on the left end, and a power button 35 on the right end. When the user presses any of the physical buttons 31 to 35, the electronic control unit 2 controls the output device 3 in accordance with the pressed button 31 to 35.

[0037] When an enlargement operation is performed on the content display section 7A in Fig. 4(a), the screen transitions to second display mode 5 shown in Fig. 4(b). In second display mode 5, one content display section 7A enlarged to approximately twice the size of the content display section 7 displayed in first display mode 4 is displayed side by side with a content display section 7B of the same size as the content display section 7 displayed in first display mode 4. This allows audio information to be displayed in an easy-to-read manner while also displaying call information.

[0038] When an enlargement operation is performed on the content display section 7A in Fig. 4(b), the screen transitions to a third display mode 6 shown in Fig. 4(c). In the third display mode 6, only one content display section 7A is displayed. Note that the launcher display area 8 may continue to be displayed without changing in any of the display modes 4, 5, and 6, or may be switched to non-display mode in the third display mode 6, for example.

[0039] [2-3. Display Reduction Operation] In the display device 1 of this embodiment, a display reduction operation by the user causes a screen transition from the third display mode 6 to the second display mode 5, and also causes a screen transition from the second display mode 5 to the first display mode 4. The display reduction operation is a predetermined operation set according to the output device 3 (or an accessory device of the output device 3). For example, if a touch panel device is attached, a touch operation or a swipe operation on an image or screen is set as the display reduction operation. Furthermore, if an input device is attached, a click operation or a press operation on a keyboard, physical button, or touchpad can be set as the display reduction operation. Only one display reduction operation may be set, or multiple display reduction operations may be set.

[0040] In the display device 1 of this embodiment, the display reduction operation includes a pressing operation on the home button 31 (physical button). That is, by pressing the home button 31 once, the content display unit 7 changes from the full screen size 13 of the third display mode 6 to the second size 12 of the second display mode 5, and by pressing the home button 31 again, the content display unit 7 changes from the second size 12 of the second display mode 5 to the first size 11 of the first display mode 4. In this way, the display enlargement operation and the display reduction operation are separate operations performed in separate locations, so the user is not confused.

[0041] The screen transition in the shrinking direction caused by pressing the home button 31 may be performed in the reverse order of the screen transition in the enlargement direction. For example, if the screen transition is performed in the direction in which the content display unit 7A expands in the order of Figures 4(a), 4(b), and 4(c), the content display unit 7A will shrink in the order of Figures 4(c), 4(b), and 4(a). By transitioning the screen in this way, the display switches to one that is familiar to the user, improving usability for the user.

[0042] In the display device 1 of this embodiment, a swipe operation in a predetermined direction is included in the display reduction operation that transitions the screen from the second display mode 5 to the first display mode 4. Specifically, when the content display section 7 that is enlarged and displayed at the edge of the display screen 10 in the second display mode 5 or a content display section 7 on the same screen is swiped toward the edge, the screen transitions to the first display mode 4.

[0043] For example, in the case of second display mode 5 shown in FIG. 2(b), the content display section 7A of second size 12 is located on the left side, so the predetermined direction is the leftward direction. In other words, in FIG. 2(b), swiping content display section 7A or content display section 7B or 7C on the same screen to the left is a display reduction operation. This swipe operation changes content display section 7A from second size 12 to first size 11, resulting in first display mode 4 shown in FIG. 2(a). Note that in second display mode 5 shown in FIG. 2(b), even if content display section 7A, 7B, or 7C is swiped to the right, content display section 7A does not reduce, and the second size 12 is maintained.

[0044] [3. Effects] (1) The above-described display device 1 is provided with at least three display modes. The first display mode 4 is a mode in which a plurality of content display sections 7 displaying content information are displayed side by side on the same screen (display screen 10). The second display mode 5 is a mode in which a selected content display section 7 is displayed side by side with other content display sections 7 on the same screen while being enlarged to include the area of ​​the adjacent content display section 7. The third display mode 6 is a mode in which a single content display section 7 is displayed full-screen. Furthermore, a user's display enlargement operation transitions the screen from the first display mode 4 to the second display mode 5 and from the second display mode 5 to the third display mode 6, thereby meeting various user needs and improving the user experience.

[0045] For example, first display mode 4 and second display mode 5 can meet the needs of users who want to view multiple pieces of content information, second display mode 5 can meet the needs of users who want to enlarge one piece of content information and view it together with other pieces of content information, and third display mode 6 can meet the needs of users who want to view only one piece of content information on a large screen.

[0046] (2) In the above-described display device 1, the amount of information in the second area 22 increases as the screen transitions in accordance with the display enlargement operation. In this way, not only does the size (display area, character size, etc.) of the content display unit 7 increase, but the amount of content information displayed therein also increases, so that more information can be provided to the user, further improving the user experience.

[0047] (3) In addition, in the above-described display device 1, as shown in Figures 3(a) to 3(c), each content display unit 7 is provided with a first area 21 indicating the title of the content information and a second area 22 indicating the content of the content information, and the display enlargement operation includes a touch operation on the first area 21. As a result, the user can change the screen by simply touching the first area 21 indicating the title of the content display unit 7 that the user wants to enlarge, thereby enabling the screen to be changed with a simple operation and improving operability.

[0048] (4) In the above-described display device 1, a user's display reduction operation causes a screen transition from the third display mode 6 to the second display mode 5, and also causes a screen transition from the second display mode 5 to the first display mode 4. In this way, the display mode can be switched step by step in the reduction direction, thereby improving the user experience.

[0049] (5) Furthermore, in the above-described display device 1, the display reduction operation includes pressing a physical button (e.g., the home button 31) that is provided separately from the display screen 10 on which the content display unit 7 is displayed, making it easy to identify the location of the operation. Furthermore, if the display enlargement operation and the display reduction operation are set as separate operations for different locations (i.e., within a predetermined area of ​​the display screen 10 or on the physical button 31 outside the display screen 10), the user is less likely to make an error in the operation, and operability can be improved.

[0050] (6) Furthermore, in the above-described display device 1, the display reduction operation when transitioning the screen from the second display mode 5 to the first display mode 4 includes swiping the content display portion 7, which is enlarged and displayed at an edge of the display screen 10 in the second display mode 5, or a content display portion 7 located on the same screen, toward that edge. This improves operability. Furthermore, when a swipe operation is performed toward the side where the content display portion 7 in the second size 12 is located (the side offset to the left or right), the content display portion 7 switches (becomes smaller) from the second size 12 to the first size 11, making it easier to intuitively understand the swipe operation and the screen transition.

[0051] 4(a) to 4(c), in the first display mode 4, three content display sections 7 of the first size 11 are displayed side by side in a horizontal row, in the second display mode 5, a content display section 7 of the second size 12 and a content display section 7 of the first size 11 are displayed side by side, and in the third display mode 6, only one content display section 7 is displayed at full screen size 13. In this way, if the display screen 10 has enough space to accommodate three content display sections 7 of the smallest size (first size 11) (i.e., three units), and the space is enlarged or reduced by one unit each time the three display modes 4, 5, and 6 are switched, the user can be given a natural impression when switching between the three display modes 4, 5, and 6.

[0052] [4. Other] The display device 1 described above is an example and is not limited to the above. For example, in the specific example shown in Figures 4(a) to 4(c), a launcher display area 8 is provided within the display screen 10, but the launcher display area 8 is not essential. Also, in this specific example, an operation unit 30 is provided separately from the display screen 10 (outside the display screen 10) and includes an array of physical buttons 31 to 35 that can be operated by the user. However, the physical buttons 31 to 35 are merely an example, and the operation unit 30 may be omitted. Note that if the display reduction operation includes a physical button pressing operation, the physical button pressing operation may be a physical button 32 to 35 other than the home button 31.

[0053] Furthermore, the screen transition when a display reduction operation is performed is not limited to the reverse order of the screen transition when the screen is expanded. For example, when a predetermined display reduction operation is performed in the third display mode 6, the second display mode 5 may be skipped and the display mode may be switched to the first display mode 4. Note that the display expansion operation and the display reduction operation may be different operations on the same object (for example, a predetermined display area or a physical button).

[0054] In the above embodiment, a case has been illustrated in which multiple content display sections 7 displayed in first display mode 4 all have the same screen size (first size 11), but content display sections 7 of different screen sizes may also be displayed side by side in first display mode 4. For example, when five content display sections 7 are displayed in first display mode 4, they may be arranged like an Olympic rings symbol, with the top three content display sections 7 being different sizes from the bottom two content display sections 7. In such a case, the second size 12 may not be approximately twice the first size 11, depending on the size of the content display section 7 that is selected and enlarged.

[0055] Furthermore, in second display mode 5, the content display portion 7 displayed alongside one enlarged content display portion 7 on the same screen does not have to be the first size 11. For example, the content display portion 7 displayed in first display mode 4 may be displayed in a reduced size compared to the size in first display mode 4 or may be changed to a square shape so that the entire content display portion 7 is also displayed in second display mode 5.

[0056] In the above embodiment, the display device 1 is illustrated as being provided with three display modes: the first display mode 4, the second display mode 5, and the third display mode 6. However, other display modes may be provided. For example, a display mode (fourth display mode) may be provided in which one of the multiple content display sections 7 selected by the user is enlarged and displayed in the upper half of the display screen 10, and the remaining content display sections 7 are displayed side by side below the enlarged content display section 7.

[0057] The present invention is applicable to the manufacturing industry of display devices mounted on vehicles, and also applicable to the manufacturing industry of vehicles equipped with such display devices.
