Description

  The present invention relates to a mobile terminal device, a screen display method for the mobile terminal device, and a computer program.

  The development of portable information terminals such as portable telephones is remarkable.

  Various techniques related to such a background are known (see, for example, Patent Documents 1 to 7).

  For example, Patent Document 1 discloses a portable information terminal and an information processing system using the portable information terminal, which enlarges an area of an image to be displayed and relaxes or eliminates a restriction on a display target. Specifically, when the display unit of the portable information terminal is opened, a first liquid crystal display is arranged on the door side and a second liquid crystal display is arranged on the apparatus main body side. Therefore, it is possible to display information such as characters and images on a substantially large screen using these two liquid crystal displays. The information processing system has a large-screen server that handles large-screen images and a small-screen server that handles small-screen images. By switching between these, you can adapt to the size of the display. Yes.

  Further, for example, Patent Document 2 discloses a game screen display method using a touch panel, in which a variation in the operation of the player object is provided and the game performance is improved while being a simple operation. Specifically, when the selected character with the ball enters the centering area, a button switch image for “centering” is displayed on the second LCD provided with the touch panel. When the player touches the button switch image, the selected character performs “centering”, but the target point changes depending on which part of the button switch image the player touches. Each point in the button switch image corresponds to each point in the centering area in the game field.

  Further, for example, Patent Document 3 relates to a two-screen display game apparatus and its game program, and as a wide game space, two different background screens or courses (courses, etc.) that are mutually related are separately displayed on each display screen. It is disclosed that the game progresses while going back and forth between two courses displayed on each display screen. Specifically, two display screens including a first and a second display screen (display unit) are provided. One display screen is a first course, and the other display screen is a second course. Etc., and the communication path is displayed so that the user can go back and forth between the first course and the second course. While the player character is moving on the course of one display screen, the player character determines that the movement to the other display screen or the course can be changed at the timing when a communication path that can move to the other display screen appears. Change the course and move the other course.

  Further, for example, Patent Document 4 discloses that, in a film-type seating detection electrostatic capacitance sensor, a sense of incongruity at the time of seating is reduced and manufacturing is facilitated. Specifically, the mat electrode of the two-electrode film type capacitive sensor is composed of an upper electrode and a lower electrode formed on both surfaces of the resin film. Further, a resin coating layer that covers the upper electrode and the lower electrode is provided.

  For example, Patent Document 5 discloses providing a display unit having a large display screen with respect to the main body while maintaining compactness. Specifically, it has a display means with a foldable and unfoldable vari-angle mechanism, and a detection means for detecting the position of the display means, and in the folded state by the position of the display means detected by the detection means, The display screen is divided into two and the same image is displayed on both sides. In the unfolded state, the display method is switched so that the image is displayed on the entire display area without dividing the display screen.

  Further, for example, in Patent Document 6, in an alkaline storage battery electrode including a core material in which a plurality of through-holes are formed and an electrode active material layer, both the electronic conductivity and mechanical strength of the core material are improved. It is disclosed to improve the energy density and output of a storage battery. Specifically, a core material in which a plurality of through holes are formed in a lattice shape is used as the core material. The through hole has a substantially rectangular shape composed of two opposite sides and another two opposite sides. Further, of the two sets of opposing sides, the one set of sides is provided substantially parallel to the end portion along the longitudinal direction of the core member. The other set of sides is provided substantially parallel to the direction perpendicular to the end along the longitudinal direction of the core material.

  Further, for example, in Patent Document 7, as an electronic device and a control method thereof, a plurality of display screens are provided, and information displayed on the display screen is operated using a slide operation or a rotation operation of the display screen by a user as a trigger Is disclosed. Specifically, it is an electronic device that can display information on a plurality of two display screens that are relatively movably connected, and within a predetermined time from a first position where the display screens have a predetermined positional relationship. In addition, when a second position other than the first position is detected and the first position is detected again, a trigger signal is generated and the operating system and / or the application are operated.

Japanese Patent No. 4163355 Japanese Patent No. 4127536 JP 2008-000241 A Japanese Patent No. 4362786 JP 2009-089328 A Republished WO2010 / 114007 JP 2012-208608 A

  FIG. 8 shows a configuration of a display screen of a general portable terminal device having a plurality of display screens. As shown in the figure, an ordinary general portable terminal device is configured by arranging display screens of a plurality of display devices in a matrix, for example. That is, an ordinary general portable terminal device can configure one display screen by using the plurality of display screens. However, since the portable terminal device shown in FIG. 8 is a general and virtual portable terminal device for explanation, the display screen is a fixed display screen. That is, the display contents are not shown to be changed depending on the orientation of the mobile terminal device when the casing is opened and closed, as in an actual mobile terminal device.

  The technique described in Patent Document 1 includes a first liquid crystal display on the door side and a second liquid crystal display on the apparatus main body side. Therefore, it is possible to display information such as characters and images on a substantially large screen using these two liquid crystal displays. However, it is limited only to the enlargement of the screen, and it is not considered to change the display method by considering the total amount of screen information to be displayed including related information.

  In addition, the technique described in Patent Document 2 is a foldable two-screen terminal (such as a game), and one side is a game main part and the other side is an operation panel. It has the above convenience. However, two screens are not displayed as one screen.

  The technique described in Patent Document 3 provides a display screen for two screens including a first display screen and a second display screen. One display screen displays the first course and the like on the other display screen. Displays the second course or the like. In addition, a communication path is displayed so that the first course can be moved between the first course and the second course, and the first and second display screens are related to each other so as to be visible to the user. Yes. This is intended to improve the visibility and operability of the user, but the display content is not changed in accordance with the opening direction (orientation) when the terminal device is opened or closed.

  The technique described in Patent Document 4 detects whether or not multi-touch extends over two screens when a user performs a touch operation on a foldable two-screen touch panel. Thereby, it is determined how to display the display content such as the next page transition screen on the first display screen and the second display screen in the current display mode. In addition, as display modes, one application display mode: a mode in which one application is displayed using both display screens of the first display screen and the second display screen, two application display mode: first display screen and first display screen Mode for displaying one application on each display panel with two display screens). However, since switching to the 1-appli display mode is not automatically performed when the terminal device is opened and closed, the number of program steps required for switching the basic operation of the application when the user opens the terminal device cannot be reduced.

  The technique described in Patent Document 5 includes a display unit with a foldable and unfoldable vari-angle mechanism, and a detection unit that detects the position of the display unit, and the position of the display unit detected by the detection unit. Thus, in the folded state, the display screen is divided into two and the same image is displayed on both sides. In the unfolded state, the display method is switched so that the image is displayed on the entire display area without dividing the display screen. However, even if this makes it possible to provide a display unit with a large display screen to the main unit while maintaining compactness, the total amount of screen information to be displayed, including related information, can be provided. It has not been taken into consideration until the display method is changed by considering it.

  Moreover, the technique described in Patent Document 6 displays different information on the two screens in a terminal device having two display screens including a first display screen and a second display screen. For example, an application (for example, a browser) is displayed on the first display screen, and an application (for example, mail software) different from the first display screen is displayed on the other second display screen. It is intended to improve the user's operational convenience by activating both applications together with this display. However, the technique described in Patent Document 6 does not take into account the display of the two screens as one screen when switching from “vertical closed state to“ vertical open state ”.

  Furthermore, the technique described in Patent Document 7 determines a first position (a state in which the terminal is most opened) and a second position (other than a state in which the terminal is most opened). The second position is detected. After that, when the first position is detected again, a trigger signal is generated, and the screen display of each application is displayed and operated in a single screen configuration (example of operation, browser history back, enlarged display in a single screen configuration when selected, E-book pages).

  However, the above trigger signal is only a trigger signal for measuring “first position → second position → first position” in the timer. Therefore, depending on the timer timing, a time lag occurs in the user switching operation. Convenience will be impaired. In addition, the technique described in Patent Document 7 only determines the positions of the first position and the second position, and considers that it may not be necessary to switch the display depending on the user usage scene (display contents). It has not been. Incidentally, the case where the user does not want to switch the display is, for example, a case where the user accidentally switches to the second position and returns to the first position while browsing the electronic book at the first position. That is, in such a case, even though the user's browsing is not yet finished, the page is turned.

  The objective of this invention is providing the screen display method of a portable terminal device, a portable terminal device, and a computer program which solve the subject mentioned above.

  In order to solve the above-described problem, according to the first embodiment of the present invention, the portable terminal device includes a two-screen touch panel attached to a foldable casing and a control unit, and the control unit is folded.

FIG. 6B shows display patterns 4, 5, and 6 that are displayed when the terminal housing is opened from the laterally closed state 2 shown in FIG.

  FIG. 7 is a flowchart showing the procedure of the display operation when the terminal housing of the mobile terminal device (mobile phone device 100) according to the embodiment of the present invention is opened. Hereinafter, the procedure of the display operation when the terminal casing of the mobile terminal device (mobile phone device 100) according to the embodiment of the present invention is opened using the flowchart shown in FIG. 7 with reference to FIGS. Will be explained. In addition, in the flowchart shown in FIG. 7, the display operation when displaying on the display unit 1 (104a) and the display unit 2 (104b) when the user opens the terminal housing is shown in the display patterns shown in FIGS. (1-6) are shown separately.

  Further, for example, when a user starts a browser in the mobile terminal device (mobile phone device 100) according to the embodiment of the present invention, the basic operation flow of the browser is “Home” → “Browser startup (default page Display) "→" display the linked page selected by the user ". Thereafter, as shown in FIG. 1, when the user opens the casing of the terminal device from the closed state to the open state, in step S <b> 1, the control unit 101 displays the terminal device when the user opens the terminal housing. It is determined whether the orientation is vertical or horizontal. As a result, when the orientation of the terminal device is vertical, the process proceeds to step S2, and when the orientation of the terminal device is landscape, the process proceeds to step S7.

  Here, the case where the orientation of the terminal device is in the vertical orientation means more specifically that the state before the terminal device is opened is the longitudinal closed state 1 shown in FIG. 3A or FIG. This is the case in the vertical closed state 2 shown in FIG.

  In step S2, for example, the control unit 101 compares the X direction of various contents shown in FIG. 4 with the X direction of the liquid crystal screen size. As a result, if the display size of the various contents is larger than the liquid crystal screen size, the process proceeds to step S3. If the display size of the various contents is not larger than the liquid crystal screen size, the process proceeds to step S4. In step S <b> 3, the control unit 101 displays information including the content as the display pattern 1 on the touch panel 10 as illustrated in FIG. 5A or FIG.

  In step S4, the control unit 101 determines whether or not the transition to the detail screen selected by the application is possible. If the transition to the detail screen selected by the application is possible, the process proceeds to step S5. If the transition to the detail screen selected by the application is not possible, the process proceeds to step S6.

  The case where it is necessary to perform the determination in step S4 is, for example, when the user tries to open the casing of the terminal device from the closed state to the open state. In this case, for example, it is determined whether or not it is possible to shift to the details screen of the currently selected mail in the mail list display. More specifically, it is a case where the user starts the mailer. In this case, the basic operation of the mailer is as follows: “Home” → “Mailer activation (folder list display)” → “Mail list display (mail list in each folder such as inbox)” → “Display mail details” It becomes. Here, as shown in FIG. 1, when the user tries to open the casing of the terminal device from the closed state to the open state, the mail list display displays the currently selected mail details screen. It becomes necessary to determine whether a transition is possible. The transition in the determination in step S4 includes a transition of a control flow controlled by the control unit 101 together with a transition of a display screen (page).

  In step S5, the control unit 101 displays information including the content on the one-side screen as the display pattern 2 on the one-side screen, as shown in FIG. 5C or 5D. Here, the display pattern 2 is, for example, a mail list (screen information A) + mail details (screen information B), and the screen information B is user operation screen information.

  In step S6, as shown in FIG. 5C or 5D, the control unit 101 displays the information including the content as the display pattern 3 on the one-side screen that remains the original screen. Here, as for the display pattern 3, for example, the contents of the vertical transition screen are the folder list (screen information C) + mail list (screen information A), and the screen information A is the user operation screen information. In addition, the case where step S6 is executed is, for example, a case where it is impossible to move to the selection destination because no mail is selected in the mail list display.

  In step S7, the control unit 101 compares, for example, the display size in the Y direction of various contents shown in FIG. 4 with the size in the Y direction of the liquid crystal screen. As a result, if the display size of the various contents is larger than the size of the liquid crystal screen, the process proceeds to step S8. If the display size of the various contents is not larger than the liquid crystal screen size, the process proceeds to step S9.

  In step S8, the control unit 101 displays information including the content as the display pattern 4 occupying two screens on the touch panel 10 as shown in FIG. 6A or 6B.

In step S9, the control unit 101 determines whether or not the control unit 101 can transition to the detailed screen selected by the application. If the transition to the detail screen selected by the application is possible, the process proceeds to step S10. If the transition to the detail screen selected by the application is not possible, the process proceeds to step S11.
The case where it is necessary to perform the determination in step S9 is, for example, when the user tries to open the casing of the terminal device from the closed state. In this case, for example, it is determined whether or not it is possible to shift to the details screen of the currently selected mail in the mail list display. More specifically, it is a case where the user starts the mailer. In this case, the basic operation of the mailer is as follows: “Home” → “Mailer activation (folder list display)” → “Mail list display (mail list in each folder such as inbox)” → “Display mail details” It becomes. Here, as shown in FIG. 1, when the user tries to open the casing of the terminal device from the closed state to the open state, the mail list display displays the currently selected mail details screen. It becomes necessary to determine whether a transition is possible.

  In step S10, as shown in FIG. 6A or 6B, the control unit 101 displays information including the content as a display pattern 5 on the one-side screen of the transition destination. Here, the display pattern 5 is, for example, a mail list (screen information A) + mail details (screen information B), and the screen information B is information on the user operation screen.

  In step S11, as shown in FIG. 6A or FIG. 6B, the control unit 101 displays the information including the content as the display pattern 6 on the one-side screen that remains the original screen. Here, as for the display pattern 6, for example, the content of the horizontal transition screen is the folder list (screen information C) + mail list (screen information A), and the screen information B is the user operation screen information. In addition, the case where step S11 is executed is, for example, a case where it is impossible to move to the selection destination because no mail is selected in the mail list display.

  As described above, the control unit 101 displays a one-screen configuration when the content display size is larger than the size of the liquid crystal screen, and displays a two-screen configuration otherwise. In addition, when the two-screen display is performed, the control unit 101 automatically changes the display content of the liquid crystal screen according to the situation, so that it is possible to improve user convenience.

  In addition, when the user closes the casing of the terminal device while the display patterns 1 to 3 are being displayed, it is possible to return to the vertical closed state 1 or the vertical closed state 2 described above. Similarly, when the user closes the casing of the terminal device during display of the display patterns 4 to 6, it is possible to return to the horizontal closed state 1 or the horizontal closed state 2 as described above. Therefore, not only when the user opens the casing of the terminal device but also when the casing of the terminal device is closed, the current selection screen is centered on the orientation of the terminal device. It is possible to perform automatic screen and process transition. Therefore, for example, even when the user makes a transition to the previous or next page during browsing, the user does not need to perform an operation such as a history back, and the convenience of the user is significantly improved.

  As described above, the mobile terminal device according to the embodiment of the present invention can be applied to a mobile phone device including a two-screen touch panel, and in this case, has the following effects. That is, when the display size of the content is larger than the size of the liquid crystal display area at the time of one screen, the control unit 101 determines the page of the content currently being displayed based on the direction in which the user opens the casing of the terminal device. Change to display contents including the contents of previous and next pages and display. This effect eliminates the need for screen change processing (that is, manual display switching) by a user operation when configuring a screen with enlargement or reduction of the screen size, thereby improving the convenience for the user. It is done. In addition, this effect can reduce the number of steps of the application program until the screen is displayed, so that the screen can be switched quickly.

  In the case of a portable terminal device having a foldable two-screen touch panel, when the user opens the casing of the terminal device, the control unit 101 has a content display size smaller than the liquid crystal display area for one screen. Then, it is determined whether or not the transition for the selected portion of the current page is possible. As a result, if the above transition is possible, the screen as the transition destination is switched to another screen and displayed. If the above transition is impossible, the screen with the related information added to the content of the original screen is separated. Display as a screen. Thus, in any of the above cases, the transition is performed with the screen currently being displayed as the center, so that there is an effect that the number of steps of the application program up to the screen display can be reduced. In addition, this effect can improve the convenience for the user because the user does not need to perform an operation such as history back even when the user is transitioning to the previous or next page of the currently displayed page during browsing. .

  (Other Embodiments): As another embodiment of the present invention, a method of determining whether or not a portion where the display size of various contents is larger than the liquid crystal screen size is determined based on the presence or absence of a scroll bar is also possible. In this case, the processing step (step S2) for comparing the size in the X direction of the various contents in FIG. 7 with the size in the X direction of the liquid crystal screen is changed to a processing step for determining whether or not there is scrolling in the X direction. To do. Further, the processing step (step S7) for comparing the size in the Y direction of various contents in FIG. 7 with the size in the Y direction of the liquid crystal screen is changed to a processing step for determining whether or not there is scrolling in the Y direction. .

  According to the mobile terminal device according to this embodiment, the control unit 101 determines which of the two screen states as shown in FIG. 3 is the current screen state based on the presence or absence of each scroll. can do. Thereby, the control unit 101 can perform the display switching process of the liquid crystal screen in advance at a suitable timing during the two-screen display, so that it is possible to further improve the convenience for the user. .
