Name of Applicant(s): Actual Inventor(s): Sanyo Electric Co., Ltd., of 5-5, 2-chome, Keihan-Hondori, MORIGUCHI-CITY, OSAKA Japan Mitsuji HAMA Tadahiro EMOTO Kenji KIYOTA Address for Service: DAVIES COLLISON CAVE, Patent Trademark Attorneys, of 1 Nicholson Street, Melbourne, 3000, Victoria, Australia Ph: 03 9254 2777 Fax: 03 9254 2770 Attorney Code: DM "Folding communication terminal and display control method therefor" Invention Title: The following statement is a full description of this invention, including the best method of performing it known to us:-
INO
O
BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a folding communication terminal and a display control method therefor, and in particular to a technique for controlling illumination of a display of the folding communication terminal, that is visible to the user when the folding communication terminal is in a closed state and that is capable of multicolor displaying.
Description of the Related Art In recent years mobile communication devices which are used in systems suchas PHS (Personal Handy phone System) PDC (Personal Digital Cellular telecommunication system) and CDMA (Code Division Multiple Access) have become common because of decreases in their size and weight, improvement in their communication quality, and reduction of prices of the devices themselves and call charges, and are now
IA
(NO
a must-have for young people. Recently, folding 0 0 communication terminals which are fashionable and allow -i for easy operation are extremely popular, with manufacturers competing against each other to sell folding communication terminals.
Japanese Laid-Open Patent Application Hll-74953 C discloses a technique regarding a conventional folding communication terminal, which is already well-known. In the technique the folding communication terminal is provided with a sub-display that notifies the user of information about incoming-calls and so on, even when the folding communication apparatus is in a folded state, in addition to being provided with a main display. The sub-displayisanauxiliarydisplayfordisplaying a minimum necessary amount of informationtotheuserwhenthe folding communication device is in a closed state. Generally, a sub-display which has a smaller display area and costs less than the main display is used in order to avoid increasing the size and the price of the terminal. Specifically, a color LCD (Liquid Crystal Display) is used for the main display, and a black and white LCD which can display one row of approximately ten characters is used for the sub-display.
The sub-display displays for example stand-by
\O
IND
C information showing the present time, the electric field 0 Z strength and soon during stand-by, when an incoming-call is received, a caller's telephone number, or the caller's name which has been stored beforehand in a telephone S 5 directory in correspondence with the caller's telephone number, or information showing that the caller's telephone
\O
number is not identified, and when there is new detailed information to be displayed on the main screen, the sub-display displays simplified information showing the type and number of pieces of new detailed information.
By reading the aforementioned information displayed on the sub-display, the user can know the time, who a call is from before answering, and whether there is new detailed information to be checked on the main screen, without opening the folding communication terminal.
In particular, when there is a call, the user can identify the caller while the folding communication apparatus is still closed. This saves trouble for the user who might otherwise answer a call from someone with whom they are on bad terms, a salesperson whose caller ID is unset, or a vicious stalker, resulting in unpleasantness for the user, being made to buy an unwanted product, or being entangled in a vicious crime.
In addition, the user is also saved the trouble of kO
IND
regularly having to open the folding communication terminal 0 Z to check for detailed information because the user knows whether there is new detailed information or not with the folding communication terminal closed.
As described above, operability of folding communication devices is being improved by display of O information on the sub-display, but there is a problem in that the display content is extremely difficult to read because of the small size of the sub-display. Thus there is a demand to further improve the visibility of the information displayed while the folding communication terminal is closed.
Note that another method of letting the user know the identityof a caller when the folding communication terminal is closed is to register telephone numbers with ringer melodies in the telephone directory memory in advance. If there is a ringer melody registered in correspondence with a caller's telephone number when there is an incoming-call, the corresponding ringer melody is played, letting the user knowwhothecallisfrom. Forexample, iftheuserregisters a ringer melody "I Just Called to Say I Love You" in correspondence only with his/her girl/boyfriend's telephone number, the user knows straight away that a call is from his/her girl/boyfriend when "I Just Called to Say
\O
IND
I love You" is played.
0 z However, ringers cause a disturbance at concerts, meetings and so on, meaning that manyusers set their folding communication terminals to manner mode so that they are S 5 notified of calls by a vibration, and many users ordinarily keep their folding communication terminals set to manner
\O
C mode to avoid the disturbance of unexpected ringing. This means that the method of identifying callers byringermelody is not always effective.
SUMMARY OF THE INVENTION Inviewof the statedproblem, the objectof thepresent invention is to provide a folding communication apparatus and a display method with which a user can judge an outline of notification information at a glance without reading simplified notification such as a caller' s telephone number which is displayed on the sub-display device.

When the sub-display 18 is composed of a monochrome 0 0 display device such as a black and white LCD device, it is necessary to provide at least two illumination sources, green and red, in order to differentiate, for example, between cases in which a caller's telephone number is notified and cases in which it is not, or between cases inwhichthereisnewinformationwhichhasnotbeendisplayed on the main display 2 and cases in which there is no such information. Alternatively, the sub-display 18 can be equipped with light sources of the three primary colors, and luminous display can be performed in desired colors by changing the luminous intensity ratio of each device appropriately.
Meanwhile, if the sub-display 18 is a color LCD device or the like it is not necessary to provide light sources in a plurality of colors, but is sufficient to provide a single, substantially white illumination source.
Note that when the folding communication terminal 1 is in the open state information is displayed on the main display 2, and the sub-display 18 is turned off to conserve power. Furthermore, if the side OK key 12 or the side scroll key 13 is operated while the sub-display 18 is turned off, the sub-display 18 is turned on and then is turned off again after a predetermined amount of time.

1.4.1 Stand-by processing
\O
After having its power turned on or on detecting a new radio wave from a base station (not illustrated), the folding communication terminal 1 performs position registration with the base station by transmitting and receiving signals in a predetermined series of procedures according to the control of the control unit 20 (Step Sl01), and moves into stand-by. In stand-by the folding communication terminal 1 intermittently receives incoming-communication reception signals transmitted from the base station (Step S102). It is supposed here that the folding communication terminal 1 is in the closed state (in other words, the state shown in Fig. Ic) at this point.
in Fig. 5 shows a display screen on the sub-display 18 when the folding communication terminal 1 is in the closed state in stand-by mode. The control unit 20 obtains the present time and the electric field strength from a clock circuit and an RSSI (received signal strength indication) detection unit respectively (neither is illustrated), and
\O
IND
displays stand-by information which includes the present 0 Z time (9:30 in the example) and an antenna pictograph (N expressing the electric field strength (Step 103). In addition, although not shown in the drawing, the blank space S 5 to the left of the time maybe used to display icons expressing Sthe state of set up of the terminal and whether there is
\O
incoming-mail history information. Note that since the clock circuit and the RSSI detection unit are components that are conventionally generally contained in communication terminals an explanation will be omitted.
1.4.2 Incoming-communication processing The following is a detailed explanation of the operation of the folding communication terminal 1 when the user is being paged, while an incoming-communication notification signal for a call is received and the folding communication terminal 1 is in a closed state. Note that the fact that the folding communication terminal 1 is in a closed state is detected and notified to the control unit 20 by the open/closed detection unit 19.
When an incoming-communication notification signal for a call is received while the folding communication terminal 1 is in stand-by (Step S104), the control unit judges whether the caller information included in the
\O
IND
received incoming-communication notification signal shows 0 Z the caller' stelephone number (StepSlll) If the judgement is positive the control unit 20 retrieves the name and the color retained in correspondence with the caller's telephone number from the telephone directory memory (Step S112)
\O
The control unit 20, according to whether settings permit output of sound, outputs a predetermined ringer (a ringer melody or the like) or operates a vibrator motor to start paging the user (Step 113) Then while paging the user, the control unit performs luminous display of the incoming-communication information on the sub-display 18 and the main display 2 following the following procedure.
1.4.3 Illumination color selection process The control unit 20 invokes the illumination color selection process (Step S121) Fig. 7 is a flowchart showing the illumination color selection process.
The control unit 20 judges whether the caller's telephone number is shown in the caller information (Step S151). If the judgement is negative the control unit selects red which is the first color (StepS152). Meanwhile,
\O
IND
if the judgement is positive the control unit 20 selects 0 z green which is the second color (Step S153) 1.4.4 Process for displaying incoming-communication information on the sub-display Next, returning to the flowchart in Fig. 4, the control
\O
unit 20 has incoming-communication information displayed flashing on the sub-display 18, and had the sub-display 18 illuminated with the color selected in the illumination color selection process (Step S122) Fig. 5 (Bl) through to (B3) show the display content when the caller's telephone number is notified. When the control unit 20 judges that the notified telephone number is not registered in the telephone directory number, it has the telephone number displayed flashing (Fig. 5 (BI)) When the control unit 20 judges that the telephone number is registered, it has the telephone number and the name registered in correspondence with the telephone number in the telephone directory memory (in this case "Taro Yamada") displayed flashing repeatedly in alternation (Fig. 5 (B2) and In each case the control unit 20 has the sub-display 18 illuminated in green which is chosen in the illumination color selection process.
\O
On the other hand, (Cl) to (C3) in Fig. 5 show the 0 z display content when a telephone number non-notification reason code is notified. When the non-notification reason code shows that the caller ID is unset, the control unit 20 has the content of (Cl) displayed flashing. When the reason code shows that the call is from a terminal which
\O
does not have a caller ID function, the control unit has the content of (C2) displayed flashing. When the reason code shows that the call is from a public telephone, the control unit has the content of (C3) displayed flashing.
In each case the control unit 20 has the sub-display 18 illuminated in red which is chosen in the illumination color selection process.
If the folding communication terminal 1 is put into the open state while the display of any of (Bl) to (03) is being performed, the control unit 20 detects that the folding communication terminal 1 is in an open state (in other words the state in Fig. la or Ib) according to the open/close detection switch 19 (Step S123), turns the sub-display 18 off (Step S131), and displays incoming-communication information on the main display 2.
Furthermore, when the paging ends (Step S124), the control unit 20 turns the sub-display 18 off (Step S141), and stops the ringer or the vibrator motor (Step S141).
\O
1.4.5 Incoming-communication information display process on the main display After the folding communication terminal 1 is put into the open state, the control unit 20 displays flashing on the main display 2 incoming-communication information
\O
corresponding to the content that was being displayed on the sub-display 18, and has the main display 2 illuminated in the color chosen in the illumination color selection process (Step S122) Fig.6 (BI) and (B2) show display contents when a caller's telephone number is notified. When the control unit 20 judges that the notified telephone number is not registered in the telephone directory memory, it has the telephone number displayed flashing (Fig. 6 When the control unit 20 judges that the telephone number is registered, it has the telephone number and the name registered in correspondence with the telephone number in the telephone directory memory (in this case "Taro Yamada") displayed flashing (Fig. 6 In each case the control unit 20 has the main display 2 illuminated in green which is chosen in the illumination color selection process.
On the other hand, Fig. 6 (Cl) to (C3) show the display kO content when a telephone number non-notification reason 0 Z code is notified. When the non-notification reason code N-q shows that the caller ID is unset, the control unit 20 has the content of Fig. 6 (Cl) is displayed flashing. When the reason code shows that the call is from a terminal which does not have a caller ID function, the control unit
\O
has the content of Fig. 6 (C2) displayed flashing. When the reason code shows that the call is froma public telephone, the control unit has the content of Fig. 6 (C3) displayed flashing.
In each case the control unit 20 has the main display 2 illuminated in red which is chosen in the illumination color selection process.
If the user pushes the start key 14 of the operation unit 23 while the display state is any of those shown in Fig. 6 (Bl) to (C3) (Step s133), the control unit 20 controls the transmission/reception unit 21 and the modulation/demodulation unit 22 to establish a wireless connection on the call channel, initiating a call to the caller (step S134) Furthermore, if the paging ends without the start key 14 having been pushed (Step S135), the control unit turns the main display 2 off (step S136), and stops the ringer or the vibrator motor (Step S141).

z 1.5 Modifications of the illumination color selection process Fig. 8 is a flowchart showing another illumination color selectionprocess indetail. This process is invoked at Step S121 in Fig. 4 instead of the illumination color
\O
selection process shown in Fig. 7.
In the illumination color selection process shown in Fig. 8, the control unit 20 judges whether the caller information notified on receiving a call shows the caller's telephone number (Step S161) and selects the first color red if the caller's telephone number is not shown (Step S162). If the caller's telephone number is shown, the control unit 20 judges whether the telephone number is registered in telephone directory memory (step S163), and selects the first color red if the telephone number is not registered (Step S162), or selects the second color green if the telephone number is registered (Step S164) With this illumination color selection process, Fig.
5 (Bi) is displayed flashing illuminated in red, and Fig.
(B2) and (B3) are displayed flashing alternately illuminatedingreen. Furthermore, Fig. 6 (Bi) isdisplayed flashing illuminated in red, and Fig. 6 (B2) is displayed flashing illuminated in green.

IND
C' Fig. 9 is a flowchart showing yet another illumination 0 z color selection process in detail. This process is invoked (i at Step S121 in Fig. 4 instead of the illumination color selection processes shown in Fig. 7 and Fig. 8.
In the illumination color selection process in Fig.
9 the control unit 20 judges whether the caller information
\O
notified on receiving the call shows the caller's telephone number (Step S171) and selects the first color red if the caller's telephone number is not shown (Step S172). If the caller's telephone number is shown, the control unit judges whether the telephone number is registered in telephone directory memory (step S173), and selects the first color red if the telephone number is not registered (Step S172). If the telephone number is registered, the control unit 20 judges whether color specification information is registered in correspondence with the telephone number (step S174). If color specification information is not registered, the control unit 20 selects the second color green (Step S175), and if color specification information is registered, the control unit selects the specified color (Step S176).
With this illumination color selection process, Fig.
(Bi) is displayed flashing illuminated in red, and Fig.
(B2) and (B3) are displayed in alternation illuminated
IND
C in green or a specified color (for example, bright pink 0 Sfor the user's girl/boyfriend). Furthermore, Fig. 6 (Bl) is displayed flashing illuminated in red.
1.6 Conclusion As explained, according to the folding communication terminal and the illumination color selection method of the present invention, the color of the incoming-communication display of the main display and the sub-display is changed by distinguishing between when a caller's telephonenumber is notified and when the telephone number is not notified. Therefore the user can confirm instantlywithjust a glanceatthecolorwhetherthecaller's telephone number is notified or not.
In addition, the color of the incoming-communication display is changed by distinguishing whether a notified telephone number is registered in the telephone directory memory. Therefore, the user can confirm instantly with just a glance at the color whether the call is from a registered caller.
Furthermore, when the illumination color is specified in correspondence with a notified caller's telephone number the color of the incoming-communication display is changed to the specified color. Therefore, the user can confirm with just a glance at the color that the call is from a specified caller (for example the user's girlfriend/boyfriend, family, and so on).
2. Second Embodiment The following explains the folding communication terminal of the second embodiment in detail, with reference to the drawings. Note that an explanation of items that are the same as the first embodiment is omitted, and that the explanation is mainly about the differences.
2.1 Appearance The appearance of the folding communication terminal of the second embodiment is the same as that of the first embodiment.
Incoming-communication history information is displayed on the main display 2, as well as the present time, the electric field strength, caller information and so on. The incoming-communication history information includes incoming-call history information, and incoming-mail history information which shows that there is e-mail or character mail received at the mail server.
The number, type, and reception time of new incoming-communication history information that is yet to
ID
C 1 be displayed on the main display 2 is displayed on the z sub-display 18, as well as the present time, the electric r field strength, caller information and so on.
The incoming-communication history information that is displayed on the main display 2 is called detailed information. The number, reception time, and type of the c\ undisplayed incoming-communication history information that is displayed on the sub-display 18 is called simplified information.
2.2 Function structure The function structure of the folding communication apparatus of the second embodiment is the same as that of the first embodiment.
2.3 Incoming-communication history information Fig. 10 is an example of incoming-communication history information that is written in an incoming-communication history information memory that is realized in the RAM 20b, and that is stored following a format shown by an incoming-communication history information table 400.
There is one row in the incoming-communication history information table 400 for each communication. An
\O
IND
information category column 401 retains a symbol "call", 0 z "e-mail", or "c-mail" which show respectively that a piece ,q of incoming-communication history information is for a call, an e-mail, or a character mail. A reception date/time column 402 shows the date and time that a communication was received. A caller/sender information column 403
\O
C retains information about a caller or a sender of an e-mail or a character message. A response category column 404 maintains, as a symbol showing the users response to incoming-communication, "answered" or "missed" for calls and "read" or "unread" for e-mail and character messages.
A subject column 405 retains the subject of e-mails, only for incoming-communication history information regarding e-mail. A display flag 406 retains a symbol or "0" showing whether a piece of incoming-communication history information has been displayed on the main display or not.
The incoming-communication history information is generated by the control unit 20 when an incoming-communication notification signal is received, and is recorded in the incoming-communication history table 400.
2.4 Operation Next, the operation of the folding communication
\O

terminal of the present invention having the 0 Z above-described structure will be explained with reference c-i to a flowchart and screen display examples.
Fig. 11 is a flowchart showing the overall operations of the folding communication terminal of the present invention.
\O
Fig. 12 to Fig. 15 are screen display examples of the sub-display 18 and the main display 2.
2.4.1 Stand-by processing When having its power turned on or on detecting a new radiowavefromabasestation (notillustrated), the folding communication terminal 1 performs position registration with the base station by transmitting and receiving signals in a predetermined series of procedures according to the control of the control unit 20 (Step 3201), and moves into stand-by. In stand-by the folding communication terminal 1 intermittently receives incoming-communication reception signals transmitted from the base station (Step 3202). It is supposed here that the folding communication terminal 1 is in the closed state (in other words, the state shown in Fig. Ic) at this point.
Fig. 12 shows a display screen on the sub-display 18 when the folding communication terminal 1 is in the closed
\O
IND
state in stand-by. The control unit 20 obtains the present 0 z time and the electric field strength from a clock circuit and an RSSI detection unit respectively (neither is illustrated), and displays stand-by information which includes thepresent time (9:30 inthe example) andanantenna pictograph expressing the electric field strength (Step S203). In addition, although not showing in the drawing, the blank space to the left of the time may be used to display icons expressing the state of set up of the terminal and whether there in incoming-mail history information. Note that since clock circuits and RSSI detection units are components that are conventionally generally contained in communication terminals an explanation will be omitted.
2.4.2 Incoming-communication processing and simplified information display processing When the folding communication terminal 1 is in a closed state and it receives an incoming-communication notification signal for a call, an e-mail or a character message (Step S204), the control unit 20 rings the ringer or operates the vibrator motor for a predetermined period, in accordance with the type of incoming-communication, to page the user (Step S205) In the present embodiment it is assumed that the user
\O
CI is not able to respond to the incoming-communication z straight away because for instance they are busy or not present. In other words, it is assumed that the user does notanswercalls, anddoesnotperformanoperation toconfirm S 5 incoming-communication history information for e-mail and character mail.
O The control unit 20 generates incoming-communication history information which it writes to the incoming-communication history information memory (step S206), and displays on the sub-display 18 simplified information which includes the type and reception time of the most recently received incoming-communication notification signal (Step S207).
The following is a specific example of a case in which four incoming-communication notification signals are received.
The folding communication terminal 1 receives an incoming-communication notification signal for a call at 10:00 on September 1, and the user does not answer the call. The control unit 20, after operating the ringer or the vibrator motor for a predetermined period, adds the incoming-communication history information in row 414 to the incoming-communication history information table 400, and displays simplified information about the
\O
IND
incoming-communication on the sub-display 18.
0 0 The response category of the incoming-communication history information is made to show "missed", meaning that the user did not answer the call, and the display flag is set to showing that the incoming-communication history information has not been displayed.
Fig. 12 shows a display example of the simplified information. This display shows that a call was received at 10:00, and that there is one piece of incoming-communication history information about a call (namely, the present call) that has not been displayed.
This display is maintained in stand-by until there is new incoming-communication.
The folding communication terminal 1 receives an incoming-communication notification signal showing that an e-mail was received by the mail server at 10:30 on September 1. The control unit 20, after generating a beeping sound, adds incoming-communication history information in row 415 to the incoming-communication history information table 400, and displays simplified information about the incoming-communication on the sub-display 18.
The response category of the incoming-communication history information is made to show "unread", meaning that kO
IND
the user has not read the e-mail, and the display flag is 0 z set to showing that the incoming-communication history information has not been displayed.
Fig. 12 shows a display example of the simplified information. This display shows that e-mail was received by the mail server at 10:30, and that there is one piece Sofincoming-communicationhistoryinformationaboute-mail (namely, the present e-mail) that has not been displayed.
This display is maintained in stand-by until there is new incoming-communication.
The folding communication terminal 1 receives an incoming-communicationnotificationsignalshowingthat a character mail was received by the mail server at 11:00 on September 1. The control unit 20, after generating a beeping voice, adds incoming-communication history information in row 416 to the incoming-communication history information table 400, and displays simplified information about the incoming-communication on the sub-display 18.
The response category of the incoming-communication history information is made to show "unread", meaning that the user has not read the character message, and the display flag is set to showing that the incoming-communication history information has not been displayed.
\O
IND
C' Fig. 12 shows a display example of the simplified 0 z information. This display shows that a character message was received by the mail server at 11:00, and that there is one piece of incoming-communication history information about character messages (namely, the present character message) that has not been displayed. This display is
\O
maintained in stand-by until there is new incoming-communication.
The folding communication terminal 1 receives an incoming-communication notification signal once more showing that an e-mail was received by the mail server at 11:30 on September I. The control unit 20, aftergenerating a beeping voice, adds incoming-communication history information in row 417 to the incoming-communication history information table 400, and displays simplified information about the incoming-communication on the sub-display 18.
The response category of the incoming-communication history information is made to show "unread", meaning that the user has not read the e-mail, and the display flag is set to showing that the incoming-communication history information has not been displayed.
Fig. 12 shows a display example of the simplified information. This display shows that e-mail was received
\O
IND
cl by the mail server at 11:30, and that there are two pieces 0 O of incoming-communication history information about e-mail that have not been displayed. This display is maintained in stand-by until there is new incoming-communication.
2.4.3 Illumination color selection process \OWhen the user operates the side OK key 12 or the side scroll key 13 while the folding communication terminal 1 is in stand-by or while simplified information is being displayed (Step S211), the control unit 20 invokes and executes the illumination color selection process (step S211) Fig. 16 is a flowchart showing the illumination color selection process in detail.
The control unit 20 searches the incoming-communication history information table 400 to judge whether there is any incoming-communication history information whose display flag is set to (step S251).
When there is no such information the control unit 20 selects the first color, green (step S252), and when there is such information the control unit 20 selects the second color, red (step S253) Next, returning to the flowchart in Fig. 11, the control unit 20 has the sub-display 18 illuminated in the color which selected in the illumination color selected procedure (Step S213).
As an example, when the side OK key 12 or the side scroll key 13 is operated while the simplified information of Fig. 12 is being displayed the control unit 20 has the sub-display 18 illuminated in red because there is incoming-communication history information stored in the incoming-communication history information table 400 that has not been displayed. On the other hand, when there is no incoming-communication history information stored in the incoming-communication history information table 400 that has not been displayed and the stand-by information shown in Fig. 12(A) is being displayed, the control unit lights the sub-display 18 in green if a key operation is performed.
2.4.4 Display updating process according to open/close operations If the user open the folding communication terminal 1 while it is in stand-by or is displaying simplified information, the control unit 20 detects according to the open/close detection switch 19 that the folding communication terminal 1 is in an open state (namely, the state in Fig. la or Fig. Ib) (Step S226), terminates the
\O
IND
c display on the sub-display 18 (step S221), and displays 0 z illuminated on the main display 2 incoming-communication history information corresponding to the simplified information that was being displayed on the sub-display 18 (Step S222) The control unit 20 updates the value in the display
IND
O flag column 406 of the incoming-communication history C' information table 400 for the incoming-communication history information that is being displayed on the main display 2 to "1" If the user closes the folding communication terminal 1 while the incoming-communication history information is being displayed on the main display 1, the control unit detects, according to the open/close detection switch 19, thatthe foldingcommunicationterminal 1 hasbeenclosed (namely, the state in Fig. Ic) (Step S231) Then, as well as turning off the main display 2 (Step S232), the control unit 20 searches the incoming-communication history information table 400 and, when there is incoming-communication history information whose display flag is set to displays the simplified information of the newest piece of the information, and when there is no such information, displays the stand-by information on the sub-display 18 (Step S233).
\O
IND
CI The following is a specific example of when the O incoming-communication history information shown in Fig.
is recorded in the incoming-communication history information table 400.
After the incoming-communication notification signal for the last e-mail is received, the display shown IO in Fig. 12 is performed on the sub-display 18. When the user opens the folding communication apparatus 1 while the stated display is being performed, the control unit 20 recognizes according to the open/close detection switch 19 that the folding communication terminal 1 is open, and terminates the display on the sub-display 18.
Fig. 13 shows the subsequent display contents of the main display 2 and the sub-display 18.
Since the sub-display 18 was displaying simplified information about e-mail, on terminating the display on the sub-display 18 the control unit 20 displays incoming-communication history information about the unread e-mails on the main display 2 (See Fig. 13 Furthermore, the control unit 20 updates the display flag column for the rows 417 and 415 in the incoming-communication history information table 400 to Fig. 13 shows that as unread e-mail there is an e-mail number 001 from Taro Yamada that arrived at 10:30
\O
IND
on September 1 and has a subject "About the other day", 0 z and an e-mail number 002 from [email protected] that arrived at 11:30 on September 1 and has a subject "Meeting".
Note that the e-mail number 001 is surrounded by a rectangular S 5 frame. This is to express that number 001 is highlighted, and shows that number 001 is selected. Furthermore, if
