The various keys include, for example, a dial key 18a, a cursor key 18b, a function key 18c, and an enter key 18d. Note that a touch sensor (not shown) may be mounted on the operation unit 18.

  FIG. 3 is a block diagram showing an example of the configuration of the signal processing system of the mobile phone 1 according to the embodiment of the present invention shown in FIG. 1 and FIG. The configuration of the circuit board 30 is shown.

  The circuit board 30 includes a main control unit 300 (control unit), a storage unit 301, an operation input acquisition unit 302, a communication processing unit 303, a display control unit 304, and a display memory 305. The

  In addition to the program executed by the main control unit 300, the storage unit 301 stores received information related to news, e-mail, and the like acquired via the communication processing unit 303 described later, for example, a storage composed of a nonvolatile memory. Means.

  The operation input acquisition unit 302 notifies the main control unit 300 that the key 18a to 18d is input by the operation unit 18, the input operation to the function keys 281 to 284, or the opening / closing state of the mobile phone 1 is detected. To do.

The communication processing unit 303 receives the reception information of information such as news periodically transmitted from the outside by communication, such as BCMCS, or the e-mail transmitted irregularly, and the main control such as received information and e-mail received. Delivered to part 300.
The display control unit 304 draws the reception information and mail received via the communication processing unit 303 or the display information generated by the main control unit 300 in the display memory 305, and displays the main display 13, the sub display 14, and the like. Received information, e-mail, or the like or display information drawn in synchronization with the display timing of the display unit is read and displayed on the display unit. Here, the display memory 305 is shown as a configuration block independent of the storage unit 301, but may be replaced with a partial area of the storage unit 301.

  The main control unit 300 is a central processing unit that manages and controls the storage unit 301, the operation input unit 302, the communication processing unit 303, and the display control unit 304 described above. For example, the first information in which the amount of display information such as a clock, a radio wave state, and a battery remaining amount is constant, and the second information in which the amount of display information such as information received by BCMCS, a mail text, etc. fluctuates. Any one of the above functions as a control unit that performs control to display in a predetermined display area of the sub-display 14, and in particular, the first information is displayed in the display area according to the first operation and the first operation Or the second information is displayed in the display area after the display of the first information is completed when the second operation is performed from the start of the display of the first information until the predetermined set time has elapsed. And a predetermined set time elapses If the second operation is not performed until the display of the first information is controlled so as not to display the display area of the second information after completion.

Here, the “first operation” and the “second operation” are any operation of the function keys 281 to 284 (or a side key not shown) detected by the operation input unit 302 or illustrated. This refers to an operation of shifting the cellular phone 1 detected by the open / closed state detection unit from the open state to the open state.
Note that the first operation and the second operation in the present embodiment may be the same operation or different operations. Further, any operation other than the operation of any of the function keys 281 to 284 and the opening / closing operation of the mobile phone may be performed.
In addition, the “predetermined set time” is whether or not there is an intention to display the second information from the time when the first operation is performed or the first operation is performed and the first information is displayed. This is a time set in advance to determine whether or not. The “predetermined display time” refers to a preset set time from when the first information is displayed until the display ends, and is the same as the “predetermined set time” described above. , There can be three patterns when either is small (large). Details will be described later.

The sub-display 14 is a first information display in which the amount of display information such as a clock as shown in FIG. 5 is constant by operating the function keys 281 to 284 provided on the back surface S2 of the receiver housing 2. Is possible. Since this clock display is frequently used, it is desirable that it can be performed with fewer operations, and display for a certain period of time is the minimum necessary for usability. Further, it is configured to be able to display news or the like as second information distributed from the network, received via the communication processing unit 303, and having a variable display information amount. News is distributed by multicast communication and updated at regular intervals. If the news to be displayed has a larger amount of information than the amount of information that can be displayed in the display area of the sub-display 14, the entire text can be displayed by scrolling the news. Further, in order to reduce power consumption, when the scrolling is finished, the sub display 14 is turned off and the display is finished. The sub display 14 is configured to be able to display either the first information or the second information in a predetermined display area.
In this way, by operating the function keys 281 to 284 provided on the back surface S2 of the receiving housing 2 according to the present embodiment, for example, by displaying news on the sub display 14 as shown in FIG. You can watch clocks and news without the need to set the housing open.

Note that the sub-display 14 described above has no operation of the function keys 281 to 284 provided on the back surface S2 of the receiving housing 2 after displaying the first information for power consumption suppression, and has a predetermined set time. When the period of time elapses, the display is controlled to be extinguished and the display is terminated. This set time is, for example, about 3 to 20 seconds, and is variable according to user settings. In other words, since there is no operation for displaying the first information and the display ends when a predetermined set time elapses, there is no possibility of unexpected power consumption.
FIG. 4 is a flowchart cited for explaining the operation of the display device according to the embodiment of the present invention. Here, for example, the display information amount of the clock information generated by the main control unit 300 is constant for the sub display 14 having only a display area of 11 full-width characters (22 half-width characters) here. An example will be described below in which either news or mail received via the communication processing unit 303 is displayed as the first information as the second information whose display information amount fluctuates.

First, in a standby state in which the sub-display 14 is turned off, when the user presses any one of the function keys 281 to 284 on the back surface S2 of the receiving housing 2 (first operation), an operation input is acquired. The unit 302 detects the press and passes it to the main control unit 300 as a clock display request (S401 “Yes”). Upon receiving this clock display request, the main control unit 300 performs control to generate clock information and display the clock on the sub display 14 by the display control unit 304 (S402), as shown in FIG. On the other hand, if any of the function keys 281 to 284 is not pressed by the user in step S401, it is determined that there is no clock display request (S401 “No”), and the main control unit 300 performs the first operation described above. The standby state in which the sub display 14 is turned off is continued until there is.
At this time, the main control unit 300 performs time monitoring, and monitors whether or not a function key operation has been performed from the above-described clock display request or from the start of clock display until a predetermined set time has elapsed. (S403). Then, the main control unit 300 presses any one of the function keys 281 to 284 provided on the back surface S2 of the receiving housing 2 until the predetermined set time elapses (second operation). ) (S404 “Yes”), it is interpreted that there is a news display request, and the display is switched to news display, and then the process proceeds to step S405. Note that the news here is the news received at the nearest time point when the specific key pressed (second operation) pressed in step S404 among the news stored in the storage unit 301. And The present invention is not limited to this, and any news stored in the storage unit 301 may be used. For example, unread (undisplayed) news may be preferentially displayed.
On the other hand, if any one of the function keys 281 to 284 is not pressed by the predetermined time (S404 “No”), the news display is not performed after the clock display is completed. To control.

This makes it possible to suppress unexpected power consumption when performing control for displaying either a clock with a constant display information amount or news with variable display information amount on the sub-display 14. That is, since the display information amount is constant, the watch does not consume unexpected power even if the display is continued as long as a predetermined set time is determined.
On the other hand, news has a display information amount that fluctuates, so if there is a large amount of display information, there is a risk of unexpected power consumption, but there was a function key operation that required news display before the predetermined set time passed Only in the case, that is, the news display is executed only when the user has an intention to display the news.

  In step 405, a predetermined set time set in advance is compared with a predetermined display time (S405). Here, the “predetermined set time” is to display news that is counted from when the function keys 281 to 284 are operated or when the function keys 281 to 284 are operated and the clock is displayed. This is the time set to determine whether there is an intention. The “predetermined display time” refers to a set time that is set in advance to display a clock that is counted from when the clock is displayed.

When the predetermined set time is longer than the predetermined display time in the determination process of step S405 (S405 “>”), the main control unit 300 ends the clock display after the predetermined display time has elapsed and the predetermined set time has elapsed. The display control unit 304 is controlled to start the news display later (S406). When the set time and the display time are the same (S405 “=”), or when the set time is smaller than the display time (s405 “<”), the clock display ends after the display time (set time) has elapsed. At the same time, the display control unit 304 is controlled to start the news display (S407 and S408, respectively).
Subsequently, when displaying news, the main control unit 300 compares the amount of news information with the amount of information that can be displayed in the display area of the sub-display 14, and determines whether scroll control is necessary (S409). That is, if it is determined that the amount of news information is less than the amount of information that can be displayed in the display area of the sub-display 14, it is determined that scroll display is unnecessary (S409 “<”), and the sub-display 14 is displayed without scrolling the news. The normal display to be displayed in the display area is performed (S410). On the other hand, if it is determined that the amount of news information is larger than the amount of information that can be displayed in the display area of the sub-display 14, it is determined that scroll display is necessary (S409 “>”), and all news information is displayed to the end. Scroll display is performed (S412). FIG. 6 is a diagram showing the scrolling display of the entire news sentence shown in FIG.

  Note that it is possible to determine whether the amount of information related to news display is larger or smaller than the amount of information that can be displayed in the display area of the sub-display 14 by decoding the information embedded in the header of the received information.

During normal display (S410) or scroll display (S412), when the user has requested to cancel the news display by operating the function key (any one of 281 to 284) as the third operation (S411 “Yes”) Alternatively, S414 “Yes”), the main control unit 300 can forcibly terminate the news display (S415). As a result, unnecessary display can be terminated when news display is requested unintentionally in step S404.
In addition, when the news display is normally displayed and the display is finished after a lapse of a certain time (S411 “Yes”), or after the scroll operation is finished (S413 “Yes”), the news display can be ended. . As a result, even a display having a relatively small display area such as the sub display 14 can reliably display the entire text of received information such as news.

FIG. 8 shows an example of the screen transition of the sub-display 14 that accompanies the series of processing from step S401 to S415 described above.
As shown in FIG. 8, (a) any one of the function keys 281 to 284 is pressed (first) when the sub display 14 is turned off during standby (the sub display 14 is turned off and in the standby state). Is detected, the time display as the first display shown in (b) is performed on the sub-display 14. After the clock display, a predetermined set time (for example, 3 seconds) is monitored, and when the time has elapsed, the clock display is turned off, and any one of the function keys 281 to 284 is pressed by the time (second operation). ) Is detected, news display as shown in (c) is performed. Then, the display of the news as shown in (d) is ended by scrolling the news (for example, 15 seconds are required), and then the sub-display 14 is turned off as shown in (d).
If there is the function key 281 to 284 (third operation) as a news cancel request during the normal display of news in step S410 or during the scroll display of news in step S412, the scroll display is terminated. If there is a further operation (fourth operation) of the function keys 281 to 284 different from the third operation during the scroll display of the news, other news stored in the storage unit 301, for example, step S410 Alternatively, news received by the communication processing unit 303 or unread news (undisplayed news) at the time closest to the time when the news displayed in S412 is received can be displayed on the sub-display 14.

  As described above, according to the above-described display device according to the embodiment of the present invention, either information such as a clock whose display information amount is constant or received information such as news whose display information amount is changed is sub- In a display device that performs control to display on the display area of the display 14, the user is controlled to display the received information only when it is understood that the user wants to display received information such as news. If there is no further action before the time elapses, the clock display is terminated and the received information is not displayed when a predetermined set time elapses. Can be suppressed. Further, even if the display unit has a relatively small display area such as the sub-display 14, the entire text can be reliably displayed by performing scroll display for news or the like whose display information amount fluctuates. After displaying display information such as a clock, received information such as news can be quickly displayed. In addition, even if the unintended second operation is performed and the received information is displayed by mistake, the news display can be canceled by performing the third operation, so that unnecessary display is preferably performed. It can be stopped and unexpected power consumption can be suppressed.

  In addition, the display control method according to the embodiment of the present invention includes an operation unit (for example, 281 to 184), a display unit having a predetermined display area (for example, the sub display 14), and the amount of display information is constant. A control unit (circuit board 30) that performs control to display either the first information (for example, a clock) or the second information (for example, news) whose display information amount varies in the display area. A display control method used for a display device, the step of displaying the first information in the display area according to a first operation (for example, S401 and S402 in FIG. 4), and the first operation. Alternatively, when the second operation is performed before a predetermined set time elapses from the display start of the first information, the second information is displayed after the display of the first information is finished. Steps to display in the area (for example, , S403 to S408 in FIG. 4 and when the second operation is not performed until the predetermined set time has elapsed, the second information is displayed after the display of the first information is finished. Are controlled so as not to be displayed in the display area (S404 “No” to end).

  According to the above-described display control method according to the embodiment of the present invention, the display area of the sub-display 14 displays either information such as a clock whose display information amount is constant or received information such as news whose display information amount varies. In the display control method for performing display control, the reception information is controlled to be displayed only when it is understood that the user wants to display the received information such as news, and a predetermined set time elapses. If there is no further action before, the clock display is terminated and the received information is not displayed when a predetermined set time has elapsed, thereby suppressing the risk of unexpected power consumption. it can.

  In the above-described embodiment of the present invention, it has been described that received information such as a clock or news is displayed in the display area of the sub-display 14 by operating any one of the function keys 281 to 284. These display or display switching triggers may be replaced by side keys or an opening / closing operation of the housing. The display by the sub display 14 may be replaced by the display by the main display 13 that is controlled to display either the first information or the second information in a predetermined display area. Further, although the watch is exemplified as the first information, it can be applied if the amount of display information is constant, such as the radio wave state and the remaining battery level, and the news is exemplified as the second information. The present invention can be applied if the amount of display information fluctuates, such as a mail text. In the present embodiment, the second information is displayed after the first display is finished (S406, S407, S408). However, the present invention is not limited to this, and the first display is displayed. The first display may be forcibly terminated when the second operation (operation of the function keys 281 to 284) is performed, and the second display may be performed as it is.
