Hereinafter, embodiments of the present invention will be described with reference to FIGS.
This embodiment illustrates a case where the present invention is applied to a mobile phone device as a terminal device, and FIG. 1 is an external view of the mobile phone device.
The cellular phone device has a foldable configuration in which, for example, an operation unit casing 1 and a display unit casing 2 are attached to be openable and closable via a hinge unit 3. The state which opened the display part housing | casing 2 (open style) is shown. An operation unit 4 having various keys and the like is disposed on the inner surface of the operation unit housing 1. A liquid crystal display unit 5 is disposed on the inner surface (front surface) of the display unit housing 2, and an electronic paper display unit 6 is disposed on the outer surface (back surface) thereof.

  The electronic paper display unit 6 has no power supply and can hold the current display information for a long time. For example, the electronic paper display unit 6 is configured to perform high-definition full color by stacking three color liquid crystal sheets in three layers. Yes. In this embodiment, the liquid crystal display unit 5 and the electronic paper display unit 6 are formed in substantially the same shape and size, and the liquid crystal display unit 5 functions as a main display unit, and the electronic paper display unit 6 is It is made to function as a sub display part.

FIG. 2 is a block diagram showing basic components of the mobile phone device.
The mobile phone device is provided with various functions such as a call function (voice telephone function), an e-mail function, an Internet connection function (Web access function), and a television broadcast reception function. The control unit 11 controls power from a main battery (for example, primary battery, secondary battery, fuel cell, etc.) 12 having a large power capacity or a backup battery (for example, lithium button battery, alkaline button battery, etc.) 13 having a small power capacity. It operates by the power supplied via the unit 14, and has a core central processing unit that controls the overall operation of the mobile phone device according to various programs in the storage unit 15.

  The power control unit 14 switches between the main battery 12 and the backup battery 13 in response to a power ON (ON) / OFF (OFF) operation. At that time, the main battery 12 is used as a power source during the power ON. The backup battery 13 is used as a power source while the power is off. In addition, when the power supply control unit 14 detects the remaining battery level for each of the batteries 12 and 13 and supplies the remaining battery level to the control unit 11, the control unit 11 compares the remaining battery level of the main battery 12 with the power-off threshold. If the remaining amount is less than the power-off threshold, schedule information described later is written in the electronic paper display unit 6 and then the power-off process is executed. The storage unit 15 is an internal memory, and has a program area and a data area. In this program area, a program for realizing the present embodiment in accordance with operation procedures shown in FIGS. In addition, a schedule database DB1, a ToDo database DB2, and the like, which will be described later, are stored in the data area.

  The radio communication unit 16 includes a radio unit, a baseband unit, a demultiplexing unit, and the like, and performs data transmission / reception with the nearest base station, for example, when a call function, an e-mail function, or an Internet connection function is operated. At the time of operation of the call function, a signal is taken in from the receiving side of the baseband unit and demodulated into a received baseband signal, and then the voice is output from the transmitting speaker SP via the telephone unit 17, and from the receiving microphone MC. Input voice data is captured from the telephone unit 17 and encoded into a transmission baseband signal, which is then given to the transmission side of the baseband unit and transmitted from the antenna. The operation unit 18 performs dial input, character input, command input, and the like. The control unit 11 executes processing according to an input signal from the operation unit 18. The display control unit 19 controls the display operation on the electronic paper display unit (sub display unit) 6 in addition to the display operation on the liquid crystal display unit (main display unit) 5. The RTC (real time clock module) 20 constitutes a clock unit, and the control unit 11 acquires the current date and time from the RTC 20.

FIG. 3 is a diagram for explaining the schedule database DB1.
The schedule database DB1 is a database that stores a plurality of schedule information (schedule information) in association with “series No”. This schedule information has items of “start date and time”, “end date and time”, and “content”, and is arbitrarily set by a user operation. “Start date and time” and “end date and time” are years indicating the scheduled date and time. Month / day / hour / minute information, and “content” is character information indicating specific scheduled contents. Each item of “important” and “secret” is associated with the schedule information. “Important” and “secret” indicate what type of schedule information, “Important” indicates relatively important schedule information, and “Secret” indicates schedule information that should be kept secret It is shown that. In the figure, the schedule information with the “Important” and “Secret” items circled indicates that it is important schedule information (important data) or schedule information that should be kept secret (secret data). Yes.

FIG. 4 is a diagram for explaining the ToDo database DB2.
The ToDo database DB2 constitutes an essential action list, and is a database that stores a plurality of schedule information (ToDo information) in association with “series No”. This schedule information has each item of “expiration date” and “content”, and is arbitrarily set by the user operation. “Expiration date” is the date information indicating the deadline indicating how long to act. “Content” is character information indicating the action content. Each item of “important” and “secret” is associated with the schedule information. In the figure, the schedule information with the “important” and “secret” items circled indicates that it is important schedule information (important data) or schedule information to be kept secret (secret data). Yes.

FIG. 5 is a diagram for explaining narrowing-down conditions for narrowing down the schedule information to be displayed on the electronic paper display unit 6 when the schedule information of the schedule database DB1 and the ToDo database DB2 is written and displayed on the electronic paper display unit 6. It is.
That is, in this embodiment, when the remaining battery level is less than the power-off threshold (for example, when the battery is almost exhausted) or when a power-off operation is performed, the schedule database DB1 or the ToDo database DB2 In order to make it possible to check the schedule information even when the power is off, the schedule information is written on the electronic paper display unit 6 and displayed and held. In order to narrow down the schedule information to be displayed on the electronic paper display unit 6 5 is a diagram for explaining “database flag”, “importance flag”, and “secret flag” as the narrowing-down conditions (electronic paper display conditions).

 The “database flag” is a flag for designating a database to be displayed. When the value is “0”, it indicates that neither schedule information in the schedule database DB1 nor the ToDo database DB2 is displayed. Further, when the value of the “database flag” is “1”, it indicates that only the schedule information of the schedule database DB1 is displayed, and when it is “2”, it indicates that only the schedule information of the ToDo database DB2 is displayed. 3 ″ indicates that both schedule information in the schedule database DB1 and the ToDo database DB2 are displayed. As a default value of “database flag”, for example, “0” is set.

 The “importance level flag” is a flag that is set in correspondence with important schedule information as described above. When the value is “0”, the flag in the database to be output is output regardless of whether it is important. Indicates that all schedule information is read and displayed, and when the value is “1”, only important schedule information is displayed. As described above, the “secret flag” is a flag that is set corresponding to the schedule information that should be kept secret. When the value is “0”, regardless of whether it is a secret or not, This indicates that all schedule information is displayed, and when “1”, only schedule information that should be kept secret is displayed. Note that the default values of the “importance flag” and “secret flag” are as follows. For example, “1” is set.

  Next, the operation concept of the mobile phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the Pum code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. That is, in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.

6 and 7 are flowcharts showing the overall operation of the mobile phone device that starts executing when the power is turned on.
First, the control unit 11 performs initialization processing (start-up processing) at power-on (step A1), and after performing initialization processing to clear a “display list” described later (step A2), the standby screen is displayed. It is displayed and enters a standby state (step A3). In this standby state, when the presence of an incoming call is detected (YES in step A4), an incoming call notification for generating and outputting an incoming melody is performed, and in accordance with an off-hook operation (incoming call response operation) (YES in step A5), a call-ready state is set. Call processing is performed (step A6). Then, in response to the on-hook operation (YES in step A7), the line connection is interrupted (step A8), and then the standby state is restored (step A3).

  If there is no incoming call in the standby state (NO in step A4), it is checked whether a power-off operation has been performed (step A9) or whether the remaining battery level is less than the power-off threshold (step A10). As another operation, for example, when a database setting operation is performed (YES in step A15 in FIG. 7), the process proceeds to a process of selecting and setting a display target database. That is, this database setting process is a process for updating the “database flag” which is a narrowing condition (electronic paper display condition) for narrowing down the schedule information to be displayed on the electronic paper display unit 6. A database setting screen is displayed according to the database setting operation (step A16).

  FIG. 10A is a diagram showing a database setting screen displayed in response to the database setting operation. This setting screen includes a message prompting the user to select data to be displayed when the power is turned off, and selection items include “1: schedule only”, “2: only ToDo”, “2: schedule + ToDo”, “4: “None” is displayed. Here, in order to arbitrarily select a database to be displayed from among the schedule database DB1 and the ToDo database DB2, when a selection operation for putting a check (circled in the figure) on a desired item is performed (step A17), The control unit 11 updates the value of the “database flag” in accordance with the database corresponding to the selection item (step A18). Thereby, the value of the “database flag” can be updated from the default value “0” to “1”, for example.

When the importance setting operation is performed (YES in step A19), the “importance flag” that is a narrowing condition (electronic paper display condition) for narrowing down the schedule information to be displayed on the electronic paper display unit 6 is updated. Processing is performed. First, the control unit 11 displays an importance setting screen in accordance with the importance setting operation (step A20).
FIG. 10B is a diagram showing an importance setting screen displayed in accordance with the importance setting operation. This setting screen displays a message prompting the user to select the importance level of data to be displayed when the power is turned off, and “1: important data only” and “2: all data” are displayed as selection items.

  In this importance setting screen, when a selection operation is performed to check a desired item according to the importance of the data (circled in the figure) (step A21), the control unit 11 selects “ The content of the “importance level flag” is updated (step A22). As a result, the value of the “importance flag” can be updated from the default value “1” to “0”, for example. Similarly, when a secret data setting operation is performed (YES in step A23), the “secret flag” that is a narrowing condition (electronic paper display condition) for narrowing down the schedule information to be displayed on the electronic paper display unit 6 is updated. Processing is performed.

  First, the control unit 11 displays a secret data setting screen in accordance with a secret setting operation (step A24). FIG. 10C is a diagram showing a secret data setting screen displayed in response to the secret setting operation. This setting screen displays a message for inquiring whether to display secret data when the power is turned off, and “1: display” and “2: not display” as selection items. Here, when a selection operation for putting a check (circle in the figure) in the item is performed (step A25), the control unit 11 updates the content of the “secret flag” according to the selection item (step A26). As a result, the value of the “secret flag” can be updated from the default value “1” to “0”, for example.

 When such flag update is completed (steps A18, A22, A26), the process returns to the standby state (step A3 in FIG. 6), but when other operations are performed (YES in step A27 in FIG. 7), As a process corresponding to the operation, for example, a database registration process can be performed in addition to a transmission process and a mail transmission process (step A28). Here, in the database registration process, after selecting a database to be registered from the schedule database DB1 and the ToDo database DB2, new schedule information is additionally registered for the selected database, or the existing schedule information is changed. At this time, in consideration of the importance and confidentiality of the schedule information, “important” and “secret” are registered in association with the schedule information as necessary.

 In the standby state, when a power-off operation is performed (YES in step A9), the control unit 11 shifts to the power-off process and shifts to the power-off process to forcibly turn off the power. Even when the remaining battery level is less than the power-off threshold, that is, when the remaining battery level falls below a preset value and the battery is almost exhausted (YES in step A10 in FIG. 6), the power is turned off. Before proceeding, the schedule information is written and displayed on the electronic paper display unit 6 (steps A11 to A13).

8 and 9 are flowcharts for explaining the display data extraction process (step A11 in FIG. 6) in detail.
First, the control unit 11 refers to the “database flag” and checks whether the value is “1” or “3” (step B1 in FIG. 8), “2” or “3” (see FIG. 8). 9 (step B12), if the value is “0” (NO in step B12), the display data extraction process is terminated, but if the value of the “database flag” is “1” or “3” (step B1 YES), that is, when at least the schedule database DB1 is selected as a display target, the variable i for sequentially designating the schedule information of this schedule database DB1 from its head address is set to “1” as its initial value. "Is set (step B2).

  Then, after the schedule information in the schedule database DB1 is designated to access with the variable i (step B3), the schedule information is narrowed down (steps B4 to B11). First, “start date and time” or “end date and time” is read from the designated schedule information as a schedule date and time, and it is checked whether or not this schedule date and time falls within a set period from the current date and time (step B4). That is, a date and time obtained by adding a predetermined time (for example, 24 hours) to the current date and time acquired from the RTC 20 is calculated, and it is checked whether the scheduled date and time is included in the calculated date and time from the current date and time. In other words, it is checked whether the schedule is the latest (for example, within 24 hours) from the current date and time. If the scheduled date does not fall within the set period and is not the latest schedule (NO in step B4), this variable i In order to exclude the designated schedule information from the display target, the process moves to step B10, and after adding “1” to the variable i and updating the value, has the maximum value (maximum No) of the schedule database DB1 been exceeded? However, if the value of the variable i is updated to “2” and is less than the maximum No, the process returns to step B3 described above.

  If the scheduled date and time of the schedule information specified by the variable i falls within the set period and is the most recent schedule (YES in step B4), the “database flag” as the electronic paper display condition described above, By referring to the “secret flag” or referring to “important” and “secret” associated with the schedule information of the variable i, it is determined whether or not the schedule information is a display target and displayed. If it is the target, a process of writing the schedule information of the variable i to the “display list” is performed (steps B5 to B9). That is, if the “importance flag” is “0” (NO in step B5) and the “secret flag” is also “0” (NO in step B7), it is determined whether the data is important data or secret data. Regardless, the schedule information is unconditionally written to the “display list” (step B9).

  When the “importance flag” is “0” (NO in step B5) and the “secret flag” is “1” (YES in step B7), the variable i is associated with the schedule information “ With reference to “secret”, it is determined whether the data is secret data (step B8). On the condition that the data is not secret data (NO in step B8), the schedule information is written in the “display list” as a display target (step B9). ), If it is secret data (YES in step B8), the process proceeds to step B10 in order to exclude the schedule information from display, and the value of the variable i is updated.

  On the other hand, if the “importance level flag” is “1” (YES in step B5), it is checked whether it is important data by referring to “important” associated with the schedule information of the variable i (step B6). If it is not important data (NO in step B6), the value of the variable i is updated to exclude the schedule information from being displayed (step B10). If it is important data (YES in step B6), the condition is that the “secret flag” is “0” (NO in step B8), and the schedule information is written in the “display list” (step B9). If the “secret flag” is “1” (YES in step B7) and it is secret data (YES in step B8), the value of the variable i is updated to exclude it from display (step B10). Even if the “secret flag” is “1” (YES in step B7), if it is not secret data (NO in step B8), the schedule information is written in the “display list” (step B9).

  Hereinafter, when the value of the variable i exceeds the maximum No of the schedule database DB1 by repeating the above-described operation (YES in Step B11), the flow proceeds to the flow of FIG. 9 and the “database flag” is referred to. If it is “1” (NO in step B12), since the ToDo database DB2 is not a display target, the display data extraction process is skipped, but the value of “database flag” If “2” or “3” (YES in step B12), since the ToDo database DB2 is a display target, the initial value is set to the variable i for sequentially specifying the schedule information from the head address. 1 "is set (step B13).

  Then, after designating access to the schedule information in the ToDo database DB2 with the variable i (step B14), the process for narrowing down the schedule information is repeated until the value of the variable i exceeds the maximum No in the ToDo database DB2 (steps B15 to B22). ). The schedule information narrowing process (steps B15 to B22) is a similar step corresponding to steps B4 to B11 in FIG.

  When such display data extraction processing is completed (step A11 in FIG. 6), it is checked whether data is written in the “display list” (step A12). If no data is written, the processing proceeds to power-off processing. (Step A14), if data is written in the “display list” (YES in step A12), the contents of the “display list” are written and displayed on the electronic paper display unit 6 (step A13). Then, the process proceeds to the power-off process (step A14).

  FIG. 11 is a diagram showing a display example when the content of the “display list” is displayed on the electronic paper display unit 6, and (A) shows that the value of “database flag” is “3” (schedule + ToDo), A display example in which the value of “importance flag” is “0” (all data) and the value of “secret flag” is “0” (displayed) is shown. In FIG. 11B, the value of “database flag” is “1” (schedule only), the value of “importance flag” is “1” (only important data), and the value of “secret flag” is “1” ( A display example in the case of (not displayed) is shown.

  As described above, in this embodiment, the control unit 11 causes the electronic paper display unit 6 to display the schedule information including the scheduled date and time within a predetermined time from the current date and time when the power-off is instructed. Since the process is shifted to the off process, it is possible to display the schedule information which is highly necessary when the schedule information is displayed on the electronic paper display unit 6 before the power is turned off. It is possible to prevent misunderstanding and misunderstanding by doing.

 Only the necessary information is displayed because only the schedule information of a predetermined type (database type, importance level, confidentiality level) is displayed within a predetermined time after the power is turned off. There is an effect that it can be displayed.

 Since the schedule information other than the secret data within a predetermined time after the power is turned off is displayed when the power is turned off, the secret data that the person does not want to be seen even within the predetermined time can be prevented from being displayed. There is.

  Even when the power is forcibly turned off when the remaining battery level falls below a preset value, the power can be turned off after the corresponding information is displayed on the electronic paper display unit 6.

  In the above-described embodiment, the case where the electronic paper display unit 6 is exemplified as the display unit having the memory property is shown, but other display units having the memory property of low power consumption drive may be used. . In addition, as the forced power off, the case where the remaining battery level is less than the power off threshold is shown, and the case where the power off operation is performed is shown. However, the case where the user operation is not performed for a certain period of time, that is, determined in advance. The power may be forcibly turned off when the specified no-operation time has elapsed.

In the embodiment described above, the sub-display unit disposed on the outer surface (back surface) of the display unit housing 2 is the memory display unit, but the main display disposed on the inner surface (front surface) of the display unit housing 2. The display unit may be a memory type display unit, and the arrangement position of the memory type display unit is arbitrary.
In addition to a mobile phone device, for example, a PC (Personal Computer), a PDA (Personal Digital Assistance), a digital camera, an electronic wristwatch, a music player for displaying information on a display unit having a memory property The same applies to terminal devices such as the above.
