On the other hand, in the folding portable telephone terminal of the second embodiment, the main LCD 11 is opened when the casing is opened.
When the display screen No. 1 is in a state in which it can be viewed by the user, the LCD 112 displays information for selecting and executing the next executable process that is determined irrespective of the process being executed.
Is to be displayed. The foldable mobile phone terminal according to the second embodiment will be described below.

[Display of Information on Sub LCD] FIG. 8 is a diagram for explaining display of information on the main LCD 111 and the sub LCD 112 of the folding portable telephone terminal 1 according to the second embodiment. . As described above, the second foldable mobile phone terminal 1 includes the main LCD 111 and the sub LCD 1 as shown in FIGS. 2 and 3.
12 and.

Also in the folding type portable telephone terminal of the second embodiment, the display screen of the main LCD 111 is the same as in the conventional portable telephone terminal, and
As in the case of the foldable mobile phone terminal of the first embodiment, an image corresponding to the processing executed is displayed.

On the sub LCD 112, different information is displayed when the foldable portable telephone terminal 1 is in a folded state and when it is in an opened state. Whether the mobile phone terminal 1 is in the folded state or the opened state is as described with reference to FIG.
The control unit 120 can detect the open / close detection switch 114 according to the state thereof.

Also in the second embodiment, as in the case of the first embodiment described above, when the folding portable telephone terminal 1 is in the standby state, The control unit 120 uses the sub LC
Various notification information is displayed on D112.

That is, when the foldable portable telephone terminal 1 is in the standby state and in the folded state, as shown in FIG.
Information such as the current date, the current time, the remaining battery level, and the received electric field strength is displayed for 12. Further, at the time of incoming call, the control unit 120 displays the telephone number of the called party on the sub LCD 112.

On the other hand, when the folding portable telephone terminal 1 is in the standby state and the folding portable telephone terminal 1 is open, some processing is executed in the folding portable telephone terminal 1 and an image corresponding to the processing is executed. Is the main LCD 11
1 is displayed, the control unit 120 controls the sub L
On the CD 112, an icon for selecting and executing the next executable process regardless of the currently executed process is displayed.

For example, as shown in FIG. 8B, the foldable portable telephone terminal 1 according to the present embodiment is adapted to execute a new e-mail creation process, and an e-mail creation screen is displayed. If so, the control unit 120 of the foldable mobile phone terminal 1 according to the present embodiment.
On the sub LCD 112, three icons b1,
Display b2 and b3.

In the case of the example shown in FIG. 8B, the icon b1 is an icon for executing the address book function, the icon b2 is an icon for executing the game function, and the icon b3 is the Internet. Is an icon for executing the Internet connection function for connecting to and browsing a Web page.

As described above, the control unit 120 controls the sub-LCD.
The icon for selecting and executing the next executable process or function, which is information about the operation in 112, indicates the process or function that is frequently used in the folding mobile phone terminal of the second embodiment. Displays icons for selecting and executing.

That is, the control unit 120 of the second embodiment updates the number of times of execution of each process or function each time a process or function executable by itself is executed,
I try to hold it. This information is, for example, EEP
It is stored and held in the ROM 124.

When displaying an icon on the sub LCD 112, the control unit 120 refers to the execution count history of each process and each function of the EEPROM 124, and selects and executes the top three processes and functions having the highest execution count. An icon for doing so is displayed on the sub LCD 112.

By doing so, no matter what kind of processing is performed in the foldable portable telephone terminal 1, the foldable portable telephone terminal 1 can immediately execute the frequently used processing or function. You can choose to run it.

Then, also in the case of the folding type portable telephone terminal 1 of the second embodiment, the information regarding the operation is displayed on the sub LCD 112. Moreover, sub LC
Since the touch panel 113 is attached to the display screen of D112, the sub LCD 112 is provided as information regarding the operation.
When a finger or the like is brought into contact with the touch panel on the icon corresponding to the executable process displayed in, the control unit 120 is notified of the information indicating the contact position, and the process corresponding to the icon displayed at that position is performed. It is executed by the control unit 120.

Further, in the case of the foldable portable telephone terminal of this embodiment, the executable processes and functions are hierarchically structured, but by using the display of the sub LCD 112 and the touch panel 113. , Quickly select the desired process or function without following the normal hierarchy,
Can be executed.

That is, in the case of many mobile phone terminals including the folding type mobile phone terminal of this embodiment, the user can relatively easily execute the intended processing and function. Therefore, executable processes and functions are hierarchically structured as shown in FIG. 7, for example.

In the case of the example shown in FIG. 7, basic functions such as a telephone directory function, an electronic mail function, a game execution function, and a browser function can be selected and executed from the main menu. Thus, the hierarchy to which the basic functions selectable from the main menu belong is the first hierarchy.

Then, for example, by selecting the telephone book function from the menu, the address book function, the history display function, the message memo function can be selected and executed, and when the history display function is selected and executed, the incoming call can be received. History display processing, incoming call history display processing, and transmission frequency display processing can be selected and executed.

Here, the address book function, the history display function,
The layer to which the message memo function belongs is the second layer, and the layer to which the incoming call history display process, the incoming call history display process, and the transmission frequency display process belong is the third layer. Therefore, in order to reach the third hierarchy, the first menu and the second hierarchy are sequentially passed from the main menu.

Similarly, when, for example, the mail function is selected from the menu, a received mail function for processing received mail, a send mail function for processing sent mail, a new function for creating sent mail, and various settings are made. It is possible to select and execute functions such as the setting function and center inquiry function. Here, receive mail function, send mail function, new creation function,
The setting function and center inquiry function belong to the second layer
It is a hierarchy.

When the received mail function is selected and executed, the received mail display processing and the received mail deletion processing can be selected and executed, and the transmitted mail function is selected and executed. In this case, the correction processing of the outgoing mail, the deletion processing of the outgoing mail, and the sending processing of the outgoing mail can be selected and executed. Here, display processing, deletion processing for the received mail function, and correction processing, deletion processing for the sent mail function,
The layer to which the transmission process belongs is the third layer.

Normally, when a process belonging to the third layer is to be executed, the process from the main menu to the third layer through the first layer and the second layer to the third layer, and the process belonging to the third layer are executed. become. However, in the case of the folding type mobile phone terminal according to the second embodiment, as shown in FIG.
As shown in FIG. 7, in the case where the new mail creation process of the third layer is performed in FIG. 7, if the browser is desired to be browsed, the process execution instruction input including the display of the sub LCD 112 and the touch panel 113 is input. Through the means, the desired processing can be directly selected and executed.

That is, in the case of the example of creating a new mail shown in FIG. 8, the main menu is returned to, and the URL input process of the third layer is selected through the first and second layers. , A browser browsing process irrelevant to the process currently being executed is directly selected through the process execution instruction input means configured by the display information of the sub LCD 112 and the touch panel 113, without any trouble such as execution. Can be executed.

Therefore, in order to perform a desired process, the display screen of the sub LCD 112 can be displayed without performing a troublesome operation such as terminating the process currently being executed and selecting a process to be executed next from the menu. By a simple operation of bringing a finger or the like into contact with the control unit 120, the control unit 120 causes the processing corresponding to the icon displayed on the display screen at the contact position to be executed. Therefore, the operability can be improved.

When the foldable portable telephone terminal 1 is in the standby state and no processing is being executed, the control unit 120 instructs the sub LCD 112 to, for example, Information about operations can be displayed.

That is, when the folding portable telephone terminal 1 does not execute any application function that can be executed in the standby mode, the control unit 12
0 displays an icon for selecting and executing some processes that are likely to be executed on the sub LCD 112. For example, icons for executing application functions such as an electronic mail function, a telephone directory function, a schedule management function can be displayed.

Next, the display processing of information on the sub LCD 112 at the standby time described with reference to FIG. 8 will be described. Also in the second embodiment, similarly to the case of the above-described first embodiment, the process of displaying information on the sub LCD 112 is performed in the standby process shown in FIG. . That is, also in the second embodiment, the process of displaying information on the sub LCD 112 is performed in step S107 of the standby process shown in FIG.

The control unit 120 then proceeds to step S30.
The process corresponding to the icon operated in 4 is executed (step S307). In this case, an image corresponding to the newly executed process is displayed on the main LCD 111 of the foldable mobile phone terminal 1. Then, after the processing of step S307, the control unit 120 repeats the processing from step S303.

When it is determined in the determination processing of step S305 that the display icon displayed on the sub LCD 112 has not been selected and the operation key of the key operation unit 132 has been used, the control unit 120 inputs the input. Is executed (step S308), the process shown in FIG. 9 is exited, and the process returns to the waiting process shown in FIG.

When it is determined in step S301 that the housing of the folding type portable telephone terminal is not opened, the control unit 120 detects the coordinates by the touch panel 113 attached to the display screen of the sub LCD 112. (Step S30
9) Then, the notification information at the time of standby is displayed on the sub LCD 112 (step S310), and the processing shown in FIG. 9 is exited to return to the standby processing shown in FIG.

As described above, in the foldable portable telephone terminal of this embodiment, the operation icon for selecting and executing the next executable process which is determined irrespective of the process being executed is displayed. Since it is not necessary to display information regarding the operation on the main LCD 111, the display screen of the main LCD 111 can be effectively used.

Moreover, the operation means of the sub LCD 112 and the touch panel 113 constitute an input means so that the target process can be quickly executed from the next effective processes determined according to the process currently being executed. Can be Therefore, the operability for the folding mobile phone terminal is improved.

Further, when the foldable mobile phone terminal 1 is folded, the detection output of the touch panel 113 is invalidated, so that the touch panel 113 does not cause an erroneous operation or an erroneous operation.

Further, in the case of the folding type portable telephone terminal of this embodiment, the executable processes and functions are hierarchically structured, but by using the display of the sub LCD 112 and the touch panel 113. , Quickly select the desired process or function without following the normal hierarchy,
Can be executed.

For example, the processes and functions that can be executed in the foldable portable telephone terminal 1 of this embodiment are
In the case where the hierarchical structure shown in FIG. 7 is provided, for example, even when a new e-mail is being created, the processing is interrupted and, for example, by the address book function, new data is created. It is possible to execute a desired process or function, such as registering, or executing a game by executing a game execution function, or connecting to the Internet. in this case,
Since it is not necessary to follow the hierarchical structure, it is possible to quickly select and execute the target processing.

Further, by providing the coordinate detecting means on the display screen of the sub display means, the same effect as the case where the input means is newly provided can be obtained. In particular, in the case of a mobile phone terminal, it is possible to obtain the same effect as when a new input means is provided within the range that can be operated with one hand.

Even when the sub-display means and the coordinate detection means are provided on the display screen of the sub-display means, the conventional jog dial key or the like can be used as it is.

Without decreasing the amount of information that can be displayed on the display screen of the main display means and without increasing the number of operation keys,
It is possible to quickly execute the target processing. That is, the operability of the information processing device can be improved.

Even if the sub-display means and the coordinate detecting means are provided on the display screen of the sub-display means, it is possible to prevent an erroneous operation through these.
