4 (a) and 4 (b) illustrate examples of display screens displayed on the first display and the second display according to the present invention. When the second cabinet 2 is closed (closed state), the display screen is displayed on the first display 11. For example, a menu screen is displayed on the first display 11 as an initial screen. On the menu screen, for example, as shown in Fig. 4A, icons for executing various applications are displayed. In addition to the applications registered in advance, the applications are available, for example, by downloading via the Internet. The obtained application is added to the cellular phone by installation. When the number of applications registered in advance or the number of applications increases, icons corresponding to them cannot be displayed on one display screen. In this case, as shown in FIG. 4 (b), when the second cabinet 2 is opened to form a display state with the first display 11 and the second display 21, the first display 11 is displayed on the first display 11. An icon that could not be displayed is displayed on the second display 21.

The user can execute a desired application on the first display 11 or the second display by touching a desired icon displayed on the first display 11 or the second display with a finger. At this time, for example, when the user attempts to manipulate the icon of the first display 11, his hand accidentally touches the icon of the second display 21, an unwanted application may be executed.

Therefore, in order to reduce such misoperation, in the first display 11 and the second display 21 opened, the first sleep key 40 and the second sleep key 41 are soft keys. It is arranged as (icon). The slip keys 40 and 41 are displayed near the corners of the respective displays 11 and 21 (for example, at the position in front of the right hand when viewed from the user's operation position). When the user presses the slip key of the display that is not operating, the sleep mode is set, after which the operation input to the display (touch panel) is not accepted. In addition, such a slip key is configured not to be displayed as a closed state.

5 is a flowchart illustrating a receiving process 500 of an operation input by the CPU 100 according to an embodiment of the present invention. 6 (a) and 6 (b) illustrate screen display examples of the first display and the second display when the sleep mode is set according to an embodiment of the present invention. It is correctly pointed out that various tasks performed in connection with process 500 may be performed by computer-readable media having instructions executable on a computer for performing software, hardware, firmware, or processing methods, or a combination thereof. It must be recognized. Process 500 may be stored on a computer-readable medium, such as a semiconductor memory, a magnetic disk, an optical disk, or the like, and may be accessed or executed by a CPU, such as, for example, CPU 100 in which the computer-readable medium is stored. have. Process 500 may include any number of additional or alternative tasks, the tasks shown in FIG. 5 need not be performed in the order shown, and process 500 is not described in detail herein. Can be integrated into more comprehensive procedures or processes with additional functionality. For clarity, the description of process 500 below refers to the components mentioned above in connection with FIGS. In practical embodiments, components of the mobile phone 1, 300 where portions of the processing 500 are different, such as the CPU 100, the memory module 200, the video encoder 301, the voice encoder 302. ), Key input circuit 303, communication module 304, backlight driver circuit 305, video decoder 306, audio decoder 307, external speaker 308, battery 309, power supply unit 310, The first touch panel 12, the second touch panel 22, the first sleep key 40, and the second sleep key 41 may be performed. Process 500 may have similar functionality, materials, and structure as the embodiment shown in FIGS.

The process 500 may begin by detecting whether the first touch panel 12 or the second touch panel 22 has been touched (query task S101). When one of the touch panels is touched, the CPU 100 determines whether the first sleep key 40 or the second sleep key 41 has been touched based on the position information from the touch panel. Determine (query task S102)

If it is determined that the first sleep key 40 or the second sleep key 41 is touched (YES in the query task S102), the CPU 100 determines whether the display on which the touch key is placed is currently in sleep mode. It determines (query task S103). If the display is not in the sleep mode (NO in the query task S103), the display (touch panel) is set to the sleep mode (task S104). Thereafter, the CPU 100 reduces the current supplied to the backlight of the display to lower the brightness of the backlight (task S105).

However, if the display on which the touched slip key is placed is currently in the sleep mode (YES in the query task S103), the CPU 100 releases the sleep mode of the display (task S106) to determine the backlight of the display. The luminance is returned to the normal state (task S107).

 When the sleep key 40 is touched by the user in a normal state (sleep state is released), as shown in FIG. 6A, the first display 11 (first touch panel 12). Is set to the sleep mode. At the same time, the luminance of the first display 11 is lowered and the display is dark.

On the other hand, when the sleep key 41 is touched by the user, as shown in FIG. 6B, the second display 21 is set to the sleep mode. At the same time, the brightness of the second display 21 is lowered and the display is dark. Even when the brightness is lowered, the display does not turn off, so that the screen continues to display icons.

If it is determined that the touched key is not the sleep key 40 or 41 (NO in task S102), the CPU 100 determines that the target (such as an icon for executing an application to be displayed on the display 11 or 21) is not present. It is determined whether or not it is touched to be activated / operated (query query S108). If it is determined that the object has been touched (YES in query task S108), the CPU 100 determines whether the cabinet constituting the touched display, that is, the cabinet constituting the touch panel, is in the sleep mode (the query task). S109). When it is determined that the object is not touched (NO in query task S108), it is detected again whether the first touch panel 12 or the second touch panel 22 is touched (task S101).

When the touch panel in the sleep mode is touched, the process 500 considers that the user touched the touch panel by mistake. If the touch panel is in the sleep mode (YES in query task S109), the CPU 100 prohibits the target from receiving an activation input (task S110), thereby prohibiting activation of a corresponding operation by the target. do. In this way, the process 500 performs some rest operation.

When a touch on the touch panel in the sleep mode is detected, the CPU 100 may indicate that reception of an operation on another display is prohibited on the display that is not in the sleep mode. Moreover, with this indication, or alternatively, notification of prohibition of receipt by vibration or sound (beep, alarm sound, voice, etc.) may be made. In this way, the user can easily recognize that another display is in sleep mode.

On the other hand, if it is determined that the touch panel that has been touched is not in the sleep mode (NO in query task S109), the CPU 100 executes a process corresponding to activation of the touched object (task S111).

The user can set the display (touch panel) to the sleep mode by touching the slip keys 40 and 41 so that an operation input for performing a predetermined idle operation is not accepted on the display in the sleep mode. Therefore, even when the user touches the display in the sleep mode when the user operates the other display in the normal mode, the cellular phone does not malfunction. This reduces the possibility of misoperation by the user, while providing convenience to the user.

In addition, since the brightness of the display set to the sleep mode is lowered, power consumption can be reduced. Therefore, the life of the battery can be extended, and the usage time of the mobile phone 300 can be extended. Furthermore, by lowering the brightness of the display, the user can be recognized that the display is in the sleep mode. Furthermore, since the slip keys 40 and 41 are arranged as soft keys on the displays 11 and 21, respectively, the correspondence between the respective displays 11 and 12 and the slip keys 40 and 41 becomes clear, and the slip It is easy to operate the keys 40 and 41. In addition, it is not necessary to separately install the hard sleep key in a place where the correspondence with the display is clear. In this way, the structure of the mobile phone 300 is simplified.

Various tasks performed in connection with process 700 may be performed by computer-readable media having instructions executable on a computer for performing software, hardware, firmware, and processing methods, or a combination thereof. Process 700 may be stored in a computer-readable medium, such as a semiconductor memory, a magnetic disk, an optical disk, or the like, and may be accessed or executed by a CPU, such as, for example, CPU 100 in which the computer-readable medium is stored. have. Process 700 may include any number of additional or alternative tasks, and the tasks shown in FIG. 7 need not be performed in the order shown, and process 700 is not described in detail herein. It should be correctly recognized that it can be integrated into more comprehensive procedures or processes with additional functions that do not. For clarity, the description of process 700 below refers to the components mentioned above in connection with FIGS. In practical embodiments, components of the cellular phone 1, 300 where portions of the process 700 are different, such as the CPU 100, the memory module 200, the video encoder 301, the voice encoder 302. ), Key input circuit 303, communication module 304, backlight driver circuit 305, video decoder 306, audio decoder 307, external speaker 308, battery 309, power supply unit 310, The first touch panel 12, the second touch panel 22, the first sleep key 40, and the second sleep key 41 may be performed. Process 700 may have similar functionality, materials, and structure as the embodiment shown in FIGS. Therefore, the same features, functions, and components may not be described in length here.

In one embodiment, slip keys 40 and 41 are disposed as softkeys on displays 11 and 21, respectively. Alternatively, the first sleep key 42 is disposed on the lower right side of the first display 11 on the first cabinet 1. Similarly, the second sleep key 43 is disposed on the lower right side of the second display 21 on the second cabinet 2. These slip keys 42 and 43 are provided in the vicinity of the corresponding display. In this way, since the slip keys 42 and 43 clearly correspond to the displays 11 and 21, respectively, the operability by the user is improved.

The process 700 may begin by detecting whether the first sleep key 42 or the second sleep key 43 has been touched (task S201). If any one of the sleep keys is operated (YES in query task S201), the CPU 100 determines whether the display corresponding to the operated sleep key is currently in sleep mode (task S202).

If it is determined that the display is not in the sleep mode (NO in query task S202), the CPU 100 sets the display (touch panel) to the sleep mode (task S203), and then lowers the brightness of the backlight of the display. (Task S204). Moreover, the CPU turns off the touch panel disposed on the display (task S205).

On the other hand, if it is determined that the display corresponding to the operated sleep key is currently in the sleep mode (YES in query task S202), the CPU 100 releases the sleep mode of the display (task S206), The brightness of the backlight is returned to the normal state (task S207). Further, the CPU turns on the touch panel disposed on the display to restore its function (task S208).

In the normal state, when the slip key 42 is operated by the user, as shown in Fig. 8A, the first display 11 is set to the sleep mode. At the same time, the brightness of the first display 11 is lowered and the display is dark. In addition, the first touch panel 12 does not function. On the other hand, when the sleep key 43 is operated by the user, as shown in Fig. 8B, the second display 21 is set to the sleep mode. At the same time, the brightness of the second display 21 is lowered and the display is dark. In addition, the second touch panel 22 does not function. Even when the brightness is lowered, the display is not turned off, so objects such as icons can still appear on the display.

If it is determined in task S201 that the slip keys 42 and 43 are not operated (NO in query task S201), the CPU 100 determines whether the first touch panel 12 or the second touch panel 22 has been touched. It is detected whether or not it is (task S209). At this time, if either display is set to the sleep mode, since the corresponding touch panel is turned off and does not function, even if the touch panel is touched, the position signal is not output.

When a touch is detected through the touch panel being touched (YES in query task S209), the CPU 100 determines whether the operation target is touched (task S210). After that, if it is determined that the operation target is touched (YES in query task S210), the CPU executes the processing based on the operation target (task S211). On the other hand, if the touch panel that is on is not touched and no touch is detected (NO in the query task S209), the CPU 100 again returns the first sleep key 42 or the second sleep key 43. It is determined whether is operated or not (task S201).

Further, even if a touch is detected through the touch panel being turned on (YES in query task S209), if it is not determined that the operation target is touched, the CPU 100 again returns to the first sleep key 42 or the like. It is determined whether or not the second sleep key 43 is operated (task S201).

In one embodiment, since no slip key is provided on the touch panels 12 and 22, the touch panel which is not operated can be turned off. Therefore, the power supply to the touch panel is not required, the power consumption can be further reduced, and the use time of the portable telephone can be extended.

Two operation keys of the operation key group 37 provided on the support 3 can also be used as slip keys. For example, the rearmost operation key 37a serves as a slip key for the first display 11, and the frontmost operation key 37c serves as a slip key for the second display 21. In this case, when the special operation is performed on these two operation keys, these two operation keys 37a and 37c function as slip keys. For example, when an operation (so-called pressing sustain) or the like in which the operation keys 37a and 37c are continuously pressed for several seconds is performed, it functions as a slip key.

9 (a) and 9 (b) are flowcharts illustrating processes 900A and 900B when there is an interruption due to an incoming call when setting a sleep mode according to an embodiment of the present invention. Fig. 9A shows a first operation example and Fig. 9B shows a second operation example. 10 (a) and 10 (b) show screen display examples when the processing of the first operation example according to the embodiment of the present invention is executed. 11A to 11D show screen display examples when the processing of the second operation example according to the embodiment of the present invention is executed. The processing of these first operation example and the second operation example is executed by the CPU 100 in parallel with the reception processing of FIGS. 5 and 7. The various tasks performed in connection with the processes 900A, 900B may be performed by computer-readable media having instructions executable on a computer for performing software, hardware, firmware, and processing methods, or a combination thereof. . Processes 900A, 900B may be stored on computer-readable media, such as semiconductor memory, magnetic disks, optical disks, etc., and may be accessed by a CPU, such as CPU 100, for example, on which computer-readable media are stored. Can be executed. Processes 900A and 900B may include any number of additional or alternative tasks, and the tasks shown in FIGS. 9A and 9B do not need to be performed in the order shown, It should be properly appreciated that the processes 900A, 900B can be incorporated into more comprehensive procedures or processes with additional functions not specifically described herein. For clarity, the descriptions of the processes 900A and 900B below refer to the components mentioned above in connection with FIGS. In practical embodiments, components of the cellular phone 1, 300 where portions of the processing 900A, 900B are different, such as the CPU 100, the memory module 200, the video encoder 301, the voice encoder 302, key input circuit 303, communication module 304, backlight driver circuit 305, video decoder 306, audio decoder 307, external speaker 308, battery 309, power supply unit 310 ), The first touch panel 12, the second touch panel 22, the first sleep key 40, and the second sleep key 41. Processes 900A and 900B may have similar functions, materials, and structures as the embodiments shown in FIGS. Therefore, the same features, functions, and components may not be described in length here.

A first operation example will be described with reference to FIGS. 9A and 10. In the first operation example, it is assumed that the incoming call screen of the telephone is displayed on the first display 11 exposed to the outside.

The CPU 100 monitors whether there is an incoming call (task S301). After that, if there is an incoming call (YES in query task S301), the CPU determines whether the first display 11 is in the sleep mode (task S302). If there is no incoming call (NO in query task S301), monitoring whether the incoming call is received is resumed (task S302).

As shown in Fig. 10 (a), when there is an incoming call while the first display 11 is in the sleep mode (YES in the query task S302), the CPU 100 releases the sleep mode ( Task S303), the incoming call screen is displayed on the first display 11 (task S304).

If there is an incoming call while the first display 11 is not in the sleep mode (query task S302: NO), the CPU 100 displays the incoming screen on the first display 11 (task S304). .

As shown in Figure 10 (b), the information on the destination (caller's name, photo, telephone number, etc.) is displayed on the incoming screen. In addition, an off-hook key 45 for starting a call and an on-hook key 46 for ending a call are arranged on the incoming screen as a soft key. At this time, since the sleep mode of the first display 11 is already released or not in the sleep mode, the operation of the off-hook key 45 and the on-hook key 46 can be received by the CPU 100. .

Therefore, when there is an incoming call, the user can make a telephone call by operating the off-hook key 45 immediately without operating the sleep key 40.

Next, a second example of operation will be described with reference to FIGS. 9B and 11. In this operation example, it is assumed that the incoming call screen of the telephone is displayed on the first display 11.

The CPU 100 monitors whether or not an incoming call has been received (task S311). After that, if there is an incoming call (YES in query task S311), the CPU determines whether the first display 11 is in the sleep mode (task S312). If there is no incoming call (NO in query task S311), it continues to monitor whether or not there has been incoming call (task S311).

As shown in Fig. 11A, when there is an incoming call while the first display 11 is in the sleep mode and the second display 21 is not in the sleep mode, the CPU 100 It is determined that the first display 11 is in the sleep mode (YES in the query task S312), and the incoming screen is displayed on the second display 21 as shown in Fig. 11B (task S313). .

On the other hand, as shown in Fig. 11C, when there is an incoming call while the second display 21 is in the sleep mode and the first display 11 is not in the sleep mode, the CPU 100 Determines that the first display 11 is not in the sleep mode (NO in query task S312), and displays the incoming call screen on the first display 11 as shown in FIG. Task S314).

If both of the displays 11 and 21 are not in the sleep mode, the incoming call screen is displayed on the first display 11. If both of the displays 11 and 21 are in the sleep mode, it is preferable to cancel the sleep mode of either display and then display the incoming call screen on the display. In this manner, even in the second operation example, the user can quickly make a phone call when there is an incoming call.

In the above embodiments, the case where there is an incoming call is described. However, even when there is other interrupt processing, the CPU 100 can display a screen related to the interrupt processing in a manner similar to that of FIG. For example, when an alarm is set for a time such as a meeting, the alarm notification may be interrupted at that time, and the CPU 100 may display a notification screen indicating the contents of the meeting, for example, at the same time as the alarm. . In this case, a key relating to the notification screen, for example, a key for displaying the details of the conference is arranged as a soft key on the screen, and the key becomes operable.

In the CPU 100 in the above embodiments, the CPU 100 is a soft key disposed in the first display 11 and the second display 21 in accordance with the operation of the sleep keys 40 and 41 in the sleep mode. Turn on or off. However, the CPU 100 does not depend on the operation of the softkeys (slip keys 40, 41 as icons), for example, touches on the displays 11, 21, i.e. touches on the touch panels 12, 22 (e.g., , The sleep mode may be set or released according to detection of three or more touches within a short time, continuous touch for several seconds, and the like.

In addition, the soft keys slip keys 40 and 41 and the hard keys slip keys 42 and 43 are arranged in the respective cabinets 1 and 2, so that the slip modes 40 and 41 are operated when the slip keys 40 and 41 are operated. Is set, and it is possible that the sleep mode is released when the slip keys 42 and 43 are operated. In this case, when the sleep mode is set, the target touch panel is turned off. In this way, even when the slip keys 42 and 43 are used for the release operation, the touch panels 11 and 22 can be turned off, thereby reducing the power consumption.

In the above embodiments, the sleep mode is set when the slip keys 42 and 43 are operated once, and the sleep mode is released when the slip keys 42 and 43 are operated once again. Alternatively, as in the flowchart of FIG. 12, the sleep mode may be set only while the sleep key is being pressed, and the sleep mode may be released for another time.

12 is an exemplary flowchart showing a receiving process of an operation according to an embodiment of the present invention. As shown in Fig. 12, while the sleep key is being pressed (YES in query task S221), the CPU 100 changes the corresponding display to the set sleep mode (task S222), and turns the backlight to low brightness. Lights up (Task S223). Thereafter, the corresponding touch panel is turned off (task S224).

On the other hand, when the slip key is not pressed or the slip key is released (NO in query task S221), the CPU 100 changes the corresponding display to the state in which the sleep mode is released (task S225). The backlight is turned on with normal brightness (task S226). Subsequently, the corresponding touch panel is turned on (task S227).

Next, when a touch to a touch panel that is not in the sleep mode is detected (YES in query task S228), the CPU 100 determines that the operation target is the same as if it is an operation target such as an icon (YES in query task S229). The processing based on this is executed (task S230).

On the other hand, if a touch to a touch panel that is not in the sleep mode is not detected (No in query task S229), the CPU 100 determines again whether or not the sleep key is pressed.

In addition, even when a touch to a touch panel that is not in the sleep mode is detected (YES in query task S228), and if it is not an operation target such as an icon (YES in query task S229), the CPU 100 has a sleep key. It is determined again whether or not it is pressed.

Therefore, it is possible to achieve a reduction in power consumption in a manner similar to the above embodiment.

Further, in the above embodiments, when the slip key 40 disposed on the first display 11 is touched, the first display 11 is set to the sleep mode or released from the sleep mode, and the second display 21 In the case where the slip key 41 disposed on the touch panel is touched, the second display 21 is set to the sleep mode or released from the sleep mode. However, when the slip key 40 disposed on the first display 11 is touched, the second display 21 on the opposite side may be set to the sleep mode or released from the sleep mode, or disposed on the second display 21. When the slip key 41 is touched, the first display 11 on the opposite side may be set to the sleep mode or released from the sleep mode. In this case, since the touch panel on the display side set to the sleep mode is turned off, power consumption can be reduced.

However, although the capacitive touch panel is used in the present embodiment, the present invention is not limited thereto, and a resistive touch panel, a pressure-sensitive touch panel, or the like may be used. However, in the case where a capacitive touch panel is used, if the sensitivity is high, misoperation is likely to occur because detection can be made even if the finger is close to the panel surface without contacting the panel. Therefore, in the case of using a capacitive touch panel, the importance of the present invention is more obvious.

Moreover, the first detection unit and the second detection unit are not limited to the touch panel. For example, instead of the touch panel, a sensor that detects an operation target such as an icon displayed on the display module through radio waves or an image may be used even if the display portion is not touched.

In addition, in the above embodiments, the case in which the icon is displayed on the first display 11 and the second display 21 is illustrated, but any screen may be displayed on each display. For example, the present invention can be applied to the case where an e-mail screen is displayed on the first display 11, a video is displayed on the second display 21, or a different application screen is displayed on both displays. have.

Further, in the above embodiments, the first display 11 and the second display 21 are configured to line up and down, but the first display 11 and the second display 21 line up to the left and right. May be
