Description

  The present invention relates to a mobile terminal device such as a mobile phone or a PDA (Personal Digital Assistant).

  Conventionally, a foldable mobile phone that can be opened and closed has been commercialized. In this type of mobile phone, when folded, the main screen is hidden from the outside. Therefore, in this type of mobile phone, a sub-screen smaller than the main screen or a simple sub-screen is arranged on the outer surface of the folded cabinet, and even if the main screen is hidden, the sub-screen is somewhat Is displayed (see, for example, Patent Document 1).

Conventionally, the sub screen is configured by a liquid crystal panel. However, instead of the liquid crystal panel, the sub screen may be configured by an LED array in which LEDs are arranged in a matrix. When the LED array is used in this way, the mobile phone can have a clean appearance. Since the LED array is not conspicuous when not lit, it is difficult to impair the external design of the mobile phone. In addition, since a backlight device is unnecessary, it is possible to realize a reduction in thickness and cost as compared with a liquid crystal panel.

Is output, the various function modes are processed.

  For example, the CPU 100 displays various information on the sub screen by driving the sub display 23 in a state where the second cabinet 2 is closed and the main screen is hidden from the outside. When a predetermined operation on the sub-screen is detected by the touch sensor 24, the display on the sub-screen is switched and functions related to the display on the sub-screen are executed.

  Hereinafter, various operations performed using the sub screen will be described.

<Switching from initial screen to function screen>
FIG. 3 is a diagram showing a processing flow related to display switching from the initial screen. FIG. 4 is a diagram for explaining a display switching operation from the initial screen.

  The user performs desired functions such as displaying information on new mail or displaying information on missed calls by tracing the sub screen with a finger or the like from the state where the initial screen is displayed (for example, time display). The display can be switched to the screen (hereinafter referred to as “function screen”).

  That is, the CPU 100 first displays an initial screen on the sub screen (S101), and determines whether or not the sub screen is traced from the top to the bottom with a finger or the like (S102). For example, when the touch sensor 24 detects that the contact position has moved from top to bottom, the CPU 100 determines that the sub screen has been traced from top to bottom.

  If the CPU 100 determines that the sub screen has been traced from top to bottom (S102: YES), the CPU 100 displays a function screen prepared next to the initial screen (S103). For example, a screen related to the number of new mails is displayed (see FIG. 4).

  Next, it is determined whether or not the sub screen has been tapped with a finger or the like (S104). For example, when the touch sensor 24 detects that an arbitrary position on the sub screen is touched for a short time, the CPU 100 determines that the sub screen has been tapped.

  When CPU 100 determines that the sub screen has been tapped (S104: YES), CPU 100 performs display control based on the function screen. For example, if the function screen is a screen that displays the number of new mails, the sender name of the new mail is displayed.

  On the other hand, if the sub screen is not tapped (S104: NO), the CPU 100 determines whether or not the sub screen is traced from the top to the bottom with a finger or the like (S106). If it is determined that the sub screen is traced from the top to the bottom (S106: YES), the process returns to S103 to display the next function screen. For example, the CPU 100 displays a screen relating to the number of missed calls on the phone as the next function screen (see FIG. 4). If it is determined that the sub screen has been tapped on this function screen (S104: YES), CPU 100 performs display control based on this function screen (S105). For example, if the function screen is a screen that displays the number of missed calls, the name of the missed caller is displayed.

  In this way, each time the sub screen is traced from top to bottom, the function screen is sequentially switched, and if the sub screen is tapped, display control based on the function screen at that time is performed.

<Operations related to displaying new mail information>
FIG. 5 is a diagram showing a processing flow for displaying new mail information. FIG. 6 is a diagram for explaining an operation for displaying new mail information.

  When the user wants to see more detailed mail information while the screen related to the number of newly arrived mails (the middle row in FIG. 4) is displayed, the user taps the sub screen.

  Thus, when the sub screen is tapped by the user, the CPU 100 proceeds to S105 in FIG. 3 and executes the processing flow shown in FIG. At this time, the CPU 100 first displays the sender name of the new mail on the sub screen (S201). If there are a plurality of new mails, the name of the sender with the earliest incoming date is displayed (see FIG. 6).

  Next, the CPU 100 determines whether or not the sub screen has been traced from top to bottom (S202), and whether or not the second cabinet 2 has been opened, that is, the main screen of the main display 21 faces the outside. It is determined whether or not (S205).

  When the CPU 100 determines that the sub screen has been traced (S202: YES), it determines whether there is a next sender (S203). If there is a next sender (S203: YES), the next sender name is displayed on the sub-screen (S204; see FIG. 6). If there is no next sender (S203: NO), the display of the sub screen is not switched.

  When the user wants to see the contents of the sender's e-mail displayed on the sub screen, the user opens the second cabinet 2 to expose the main screen to the outside.

  If the CPU 100 determines that the second cabinet 2 has been opened (S205: YES), it displays the content (text) of the sender's email displayed on the sub-screen on the main screen (S206).

  In addition, the user can return the display of the sub screen to the previous display by tracing the sub screen from the bottom to the top before opening the second cabinet 2. For example, if the sub-screen is traced from the bottom to the top while the lower left display in FIG. 6 is displayed, the CPU 100 displays the sub-screen on the second sender name each time the sub-screen is traced from the bottom to the top. The process of returning the screen in order from the first sender name (Mr. Yamada) to the first sender name (Mr. Tanaka) and the number of new mails (Email 2) is executed.

  Further, as shown in FIG. 7A, when the second cabinet 2 is opened in a state where the number of new mails is displayed on the sub-screen before the second cabinet 2 is opened, the CPU 100 As shown in the lower part of the figure, a process for displaying a list of new mail on the main screen is executed.

  Further, as shown in FIG. 7B, when the sender name is displayed on the sub screen before the second cabinet 2 is opened, if the sub screen is traced in either the left or right direction, Emails can also be deleted.

<Operations related to the display of missed call information>
FIG. 8 is a diagram showing a processing flow for displaying missed call information. FIG. 9 is a diagram for explaining an operation for displaying missed call information.

  When the user wants to see more detailed information when the screen regarding the number of missed calls in the lower part of FIG. 4 is displayed, the user taps the sub screen.

  Thus, when the sub screen is tapped by the user, the CPU 100 proceeds to S105 in FIG. 3 and executes the processing flow shown in FIG. At this time, the CPU 100 first displays the caller name on the sub screen (S301). If there are a plurality of missed calls, the name of the caller with the earliest call date and time is displayed (see FIG. 9).

  Next, when the sub screen is traced from the top to the bottom (S302: YES), if there is a next caller (S303: YES), the CPU 100 displays the next caller on the sub screen (S304; FIG. 9). reference).

  When the user wants to call the caller displayed on the sub screen, the user opens the second cabinet 2 to expose the main screen to the outside.

  If the CPU 100 determines that the second cabinet 2 has been opened (S305: YES), it displays the name and telephone number of the caller displayed on the sub-screen before opening on the main screen (S306). When the call start key is operated by the user (S307: YES), a call origination process is performed (S308).

<Setting / canceling security lock mode>
The mobile phone according to the present embodiment has a security lock mode function, and the user can perform mode setting / cancellation operations using the sub-screen.

  FIG. 10 is a diagram for explaining a setting / release operation of the security lock mode. FIG. 4A shows a screen for setting the security lock mode, and FIG. 4B shows a screen for releasing the security lock mode.

  One of the function screens described with reference to FIGS. 3 and 4 is provided with a function screen for security lock mode (for example, a lock mark display). When the sub screen is tapped while the function screen is displayed, if the mode is released, the screen for setting operation shown in FIG. 5A is displayed and the mode is set. If it is, the screen for the release operation shown in FIG.

  When the user traces the sub screen from the left to the right (from the key to the keyhole) with the screen of FIG. 9A displayed, the CPU 100 sets the security lock mode. Thereby, after that, the key operation of the key operation unit 11 becomes invalid.

  On the other hand, when the user traces the sub screen from the right to the left (direction in which the key is removed from the keyhole) while the screen of FIG. 5B is displayed, the CPU 100 releases the security lock mode. Thereby, the key operation of the key operation unit 11 becomes effective thereafter.

<Operation in music mode>
The mobile phone of this embodiment has a function of playing music (music mode). The user can download music from various music sites via the communication module 104. The downloaded music is stored in the memory 105. In the music mode, the CPU 100 reads out music from the memory 105 based on the user's operation and reproduces it with headphones (not shown).

  FIG. 11 is a diagram for explaining an operation in the music mode. FIG. 4A shows a screen for performing operations related to music reproduction, and FIG. 4B shows a screen for performing volume adjustment operations.

  One of the function screens described in FIG. 3 and FIG. 4 has a function screen for music mode (for example, a note mark display), and the sub screen is tapped while the function screen is displayed. Then, the operation screen shown in FIG. 11 is displayed.

  FIG. 5A shows an operation screen related to music playback, and as an example, a display during music playback is shown. On this screen, a pause button is displayed in the center, and a forward button and a return button are displayed on the left and right. For example, a user can stop music playback by tapping the pause button in the center, and can send to the next song or return to the previous song by tapping the feed button or the return button. Can do.

  FIG. 5B shows an operation screen related to volume adjustment. On this screen, when the user traces the sub screen from right to left, the volume increases according to the traced distance, and when the user traces the sub screen from left to right, the volume decreases according to the traced distance.

  Note that switching between these two operation screens is performed by, for example, tracing the sub screen up and down. Control in these music modes is performed by the CPU 100 based on the output from the touch sensor 24.

<Operations for incoming calls>
The user can perform a hands-free function activation operation or an incoming call rejection execution operation using the sub screen during an incoming call.

  FIG. 12 is a diagram showing a processing flow relating to an operation when a call is received. FIG. 13 is a diagram for explaining an operation performed when a call is received. FIG. 4A shows an operation for starting the hands-free function, and FIG. 4B shows an operation for rejecting an incoming call.

  When there is an incoming call (S401: YES), CPU 100 displays a display indicating that the call is being received on the sub-screen together with a call sound. For example, as shown in FIG. 13, a mark indicating that the call is being received is displayed, and if the caller has a registered telephone number and name, the caller name is displayed.

  Next, the CPU 100 determines whether or not the sub screen has been tapped, or whether or not the sub screen has been traced in one of the left and right directions (S403, S405).

  When the user is in a situation where he / she cannot talk with the mobile phone and wants to activate the hands-free function, the user taps the sub screen (see FIG. 13A).

  When the CPU 100 determines that the sub screen has been tapped (S403: YES), the CPU 100 activates the hands-free function (S404). Thereby, the telephone is connected and the other party's voice is output from the speaker for external notification. Thereby, the user can talk with the other party without having a mobile phone.

  On the other hand, when the user wants to reject the incoming call for any reason, the user traces the sub screen in either the left or right direction (see FIG. 13B).

  If the CPU 100 determines that it has been traced in one of the left and right directions (S405: YES), it executes call rejection (S406). As a result, the incoming call is rejected. In this case, for example, a voice message indicating that the call cannot be answered may be automatically transmitted. In addition, the incoming call at this time becomes the above-mentioned missed incoming call and the history remains.

<Operations related to scroll display>
In the mobile phone according to the present embodiment, the display of the sub screen can be set to a display (hereinafter, “scroll display”) in which information (character string or the like) flows in one direction on the sub screen. When the sub screen is scrolled, a large amount of information can be displayed on the sub display 23 without requiring an operation from the user.

  In scroll display, information flows through the sub-screen at a constant speed. However, depending on the information, there are things that the user does not need to see so much, and there are things that the user wants to see carefully. Therefore, in the present embodiment, display control is performed so that the flow of information changes by operating a predetermined on the sub screen.

  FIG. 14 is a diagram showing a processing flow for changing the flow of scroll display. FIG. 15 is a diagram for explaining an operation for changing the flow of scroll display. 15A shows an operation for accelerating the information flow, FIG. 15B shows an operation for decelerating the information flow, and FIG. 15C shows an operation for stopping the information flow. .

  When the scroll display is set in advance, the CPU 100 performs scroll display on the sub screen (S501). For example, when new mail information is displayed, as described with reference to FIG. 3, when an operation of tracing from the top to the bottom is performed on the initial screen, new mail information as shown in FIG. 15 flows. Note that new mail information can be automatically scrolled when an e-mail arrives, regardless of the operation from the initial screen.

  The CPU 100 determines whether or not the sub screen is traced in the forward direction with the information flow, whether or not the sub screen is traced in the reverse direction with respect to the information flow, or whether or not the sub screen is tapped (S502, S504, S506). If it is determined that the sub screen is traced in the forward direction (S502: YES), the information flow is accelerated (S503; see FIG. 15A), and if it is determined that the sub screen is traced in the reverse direction (S504: YES), the information flow is slowed (S505; see FIG. 15B). If it is determined that the sub screen has been tapped (S506: YES), the flow of information is stopped (S507; see FIG. 15C).

  If the state in which information flows can be adjusted arbitrarily by the user in this way, user convenience can be improved.

  As described above, according to the present embodiment, the operation operation on the sub screen is detected by the touch sensor 24, and the display of the sub screen is switched based on this detection, so that a lot of information is displayed on the sub screen. Is possible. For example, not only the number of new mails but also the sender can be displayed, and information can be displayed by other functions.

  Therefore, even if the user does not open the second cabinet 2 and expose the main screen to the outside, the user can acquire a large amount of information only from the sub screen by performing appropriate operations on the sub screen. Therefore, according to the mobile phone according to the present embodiment, user convenience can be enhanced.

  In particular, when an LED array is used for the sub-display 23, a backlight device is unnecessary and the mobile phone can be made thin. Further, since the sub screen is not conspicuous, there are advantages such as improved design. Furthermore, since the LED has excellent light directivity, the visibility of the display on the sub-screen can be improved as compared with the case where a liquid crystal panel is used.

  When the LED array is used for the sub-display 23 in this way, each LED becomes one pixel, so that the amount of information on the sub-screen tends to be smaller than when a liquid crystal panel is used. However, according to the present embodiment, as described above, the display of the sub screen can be arbitrarily switched by the user. Therefore, even if the LED array is used for the sub display 23 in this way, the user acquires a lot of information. be able to.

  Further, according to the present embodiment, when the second cabinet 2 is opened, the display related to the display of the sub screen is displayed on the main screen. For example, if the name of the sender of the e-mail is displayed on the sub screen, the text of the e-mail is displayed on the main screen. If the caller is displayed on the sub screen, the telephone number of the caller is displayed on the main screen.

  Thus, in the present embodiment, the user can check the display related to the display on the sub-screen before opening on the larger main screen only by opening the second cabinet 2. In addition, since the display (display of the mail text) advanced in the operation sequence than the display on the sub screen (display of the mail sender) is displayed on the main screen, the user can open the second cabinet 2. You can see a display that is more advanced than the display on the sub-screen. Therefore, according to the present embodiment, it is possible to improve user convenience.

  Furthermore, according to the present embodiment, the user can execute various functions on the sub screen without opening the second cabinet 2 and exposing the main screen to the outside. For example, security mode setting / cancellation, music playback operations, or operations for hands-free or call rejection can be performed by operations on the sub screen. Therefore, according to the present embodiment, user convenience can be further enhanced.

  Furthermore, in the present embodiment, since the display setting (see FIG. 15) in which information flows in one direction on the sub screen is possible, the user can use the display control to perform many settings only by looking at the sub screen. Information can be acquired. Moreover, the user can speed up, slow down, or stop the flow of information by performing a predetermined operation on the sub-screen. Therefore, if there is unnecessary information, the user can speed up the flow and skip the information, and if there is important information, the user can slow down or stop the flow and check the information carefully. Information flowing on the screen can be acquired smoothly.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made to the above embodiments.

  For example, in the above embodiment, a mobile phone has been described as an example. However, the present invention can be applied to other mobile terminal devices such as a PDA (Personal Digital Assistant).

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
