[Prior art]
In a transflective LCD (liquid crystal display unit), when the backlight is turned off, the display screen can be somewhat confirmed by reflecting external light halfway and transmitting the liquid crystal screen.
On the other hand, a transmissive LCD often used for mobile phones does not have a function of reflecting external light, so that the display content can be confirmed only when the backlight is lit. When the backlight is turned off, the screen is black.
[0003]
Furthermore, since the LCD display part of a mobile phone in recent years tends to increase in size, a large number of LEDs (light emitting diodes) are required for the backlight, and the power consumption increases when the backlight is always turned on. It is not preferable for a mobile phone powered by a battery.
For this reason, the current backlight on / off control is performed, for example, by receiving an incoming call with the folding mobile phone open or by pressing any one key button to start the backlight on, When the predetermined time has elapsed, the lighting of the backlight is terminated.
[0004]
If the key button is pressed again within a predetermined time, the backlight is turned on again for a predetermined time.
Thus, the backlight lighting time is determined in a predetermined time, such as how many seconds after the user of the cellular phone presses the key button.
Therefore, in a mobile phone having a transmissive LCD, the backlight is turned off more often, and when confirming the display screen, it cannot be confirmed unless one of the key buttons is pressed once. .
[0005]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an external view of a foldable mobile phone according to the present invention. As shown in the figure, a transmissive LCD (liquid crystal display) 11 is provided on the front surface of the foldable mobile phone 10, and the transmissive LCD 11 is set on the standby screen by the date and time, the antenna bar, the remaining battery level, and the user. In addition to the displayed image, various messages such as incoming mail and incoming calls are displayed.
[0015]
Further, a key operation unit 12 is provided on the front surface of the foldable mobile phone 10, and the key operation unit 12 allows the user to make various settings.
Further, a protective screen 15 is provided on the upper surface of the transmissive LCD 11, and the protective screen 15 prevents impact, dust, dust, etc., and protects the liquid crystal.
Further, an antenna 13 for transmitting and receiving radio waves is provided at the upper part of the foldable mobile phone 10, a battery 14 for supplying power to each block is provided at the lower storage part, and a sounder 16 for ringing a ring tone.
[0016]
FIG. 2 is a block diagram showing a schematic configuration for explaining the control operation of the folding cellular phone 10 of FIG.
As shown in the figure, the control unit 21 provided in the foldable mobile phone 10 includes a key operation unit 12, a battery 14, a sounder 16, a reception signal from the antenna 13, and a signal to the antenna 13. A wireless unit 22 for processing a transmission signal; an open / close detection circuit 23 for detecting a folded state or an unfolded state of the folding mobile phone 10; a clock unit 24 for generating date, day of the week, time, and time data; and a program A memory unit 25 for storing information such as data, an LCD driver 26 for the transmissive LCD 11, and a backlight 29 for the transmissive LCD 11 are connected.
[0017]
The control unit 21 performs overall control of the foldable mobile phone 10 and control for supplying the power of the battery 14 to each block.
Specifically, the radio unit 22 receives incoming signals for incoming mail and incoming calls from the antenna 13 and outputs transmission signals to the antenna 13 to perform frequency conversion processing. In the frequency conversion processing of the radio unit 22, here, the reception (incoming) will be described. The input reception signal is frequency-converted to a reception intermediate frequency signal by a two-stage mixer, and the signal is demodulated by a modem. The demodulated received data is output to the control unit 21.
[0018]
The transmissive LCD 11 is connected to the control unit 21 via the LCD driver 26. When the control unit 21 detects an incoming call, the control unit 21 controls the LCD driver 26 to apply a voltage to each liquid crystal element of the transmissive LCD 11, Incoming information and messages are displayed on the transmissive LCD 11.
Further, if it is a missed call, the transparent LCD 11 displays a mail incoming call icon, for example, a message “Missed call”.
[0019]
Further, even when there is no incoming call, the control unit 21 controls the LCD driver 26 to display the date / time, the antenna bar, the remaining battery level, the image set by the user on the standby screen, and the like on the transmissive LCD 11.
A backlight 29 is connected to the transmissive LCD 11, and the backlight 29 includes a backlight LED (light emitting diode) 27 and a light guide plate 28.
[0020]
The backlight LED 27 is a light source, and the light guide plate 28 allows the light of the backlight LED 27 to pass from the rear surface toward the transmissive LCD 11 so as not to reflect external light to the transmissive LCD 11.
Only when the transmissive LCD 11 is illuminated by the backlight 29 (hereinafter referred to as lighting of the backlight 29), the user can recognize the display screen driven by the LCD driver 26.
[0021]
However, if the backlight 29 is always turned on, the battery 14 will be consumed significantly. For this reason, the open / close detection circuit 23 detects whether it is folded or unfolded, and control is performed to supply power to the backlight LED 27 based on the detection result. That is, in this control, the backlight 29 is turned off in the folded state, and the backlight 29 is turned on in the unfolded state.
[0022]
In the unfolded state, even when the backlight 29 is lit, time data is detected from the clock unit 24, and the key operation unit is detected within the backlight lighting time stored in the memory unit 25 in advance. If there is no input operation from 12, the control is performed to turn off the light after a predetermined time has elapsed.
Further, the control unit 21 is provided with a backlight timer control unit 21A. The backlight timer control unit 21A is used by the user to confirm a message displayed on the transmissive LCD 11 when a missed call is received by the key operation unit 12 in advance. For the purpose of controlling the backlight 29 with a timer, the setting of “turn on for a fixed number of seconds at a fixed time interval after the backlight 29 is turned off at the time of a missed call” is performed with the operation setting and the set time interval. The number of lighting seconds is stored in the memory unit 25.
[0023]
The backlight timer control unit 21A of the control unit 21 inputs time data from the clock unit 24 as needed, receives information stored in the memory unit 25, and is set by the user after the backlight 29 is finally turned off. When time elapses, the backlight 29 is turned on for a set number of seconds, and this operation is repeated to control the intermittent lighting of the backlight 29.
[0024]
By arbitrarily changing the set time interval and the number of lighting seconds stored in the memory unit 25, it is possible to adapt the lighting intermittent time of the backlight 29 to the user's preference.
The details of the control operation performed by the backlight timer control unit 21A are stored as a program in the memory unit 25, and will be described below.
[0025]
FIG. 3 is a flowchart for explaining an example of the control operation of the backlight timer control unit 21A in FIG.
As shown in this figure, in step S30, it is assumed that the user installs the foldable mobile phone 10 on a desk or the like in a state where the user folds the mobile phone 10 so that the contents of the display screen of the transmissive LCD 11 can be easily confirmed. In the folded state, the backlight 29 is not turned on at any time, so this processing is not performed.
[0026]
In step S31, an incoming mail or telephone call is received in the unfolded state, but the incoming call is interrupted when a certain period of time elapses because the user is not aware or does not receive the call because he has left his / her seat. In this case, it is a missed call. If the user receives an incoming call, the process is terminated.
In step S32, the backlight timer control unit 21A turns on the backlight 29, controls the LCD driver 26, and transmits a mail arrival icon, a mail arrival icon indicating that a call has arrived, and a message “Missed call”. It is displayed on the LCD 11.
[0027]
In step S33, the backlight 29 is turned off when a predetermined time has elapsed.
In step S 34, the backlight timer control unit 21 A displays the mail incoming call icon and the message “Missed call” on the transparent LCD 11 without receiving an incoming call by the key operation unit 12. Since the lighting is controlled by a timer, it is detected whether the setting of “how many seconds and how many seconds have passed since the backlight 29 was last turned off” is stored in the memory unit 25.
The interval time and the lighting time for lighting can be freely set when the user sets this function by the key operation unit 12.
[0028]
If this setting is not detected, the process proceeds to step S39.
In step S35, if it is set, time data input from time to time by the clock unit 24 is detected as to whether the set time set in the memory unit 25 has elapsed since the last time the backlight 29 was turned off. .
In step S36, when the set time interval has elapsed, the backlight 29 is turned on only for the set number of seconds.
[0029]
In step S37, by turning on the backlight 29 controlled by the timer, the user notices the message at the time of the missed call displayed on the transmissive LCD 11, and confirms the content when the key operation unit 12 is pressed. Can do.
If the user does not confirm the content of the missed call message, the process returns to step S35, and the backlight 29 is turned on again for the set number of seconds after the set time interval elapses after the backlight 29 is turned off. The above operation is repeated, and the backlight 29 is turned on and off.
[0030]
In step S38, when the content of the message at the time of a missed call is confirmed, the message disappears, the timer setting is invalidated, and this process is terminated.
In step S39, if the interval time and lighting time for turning on the backlight 29 are not set in the memory unit 25 and the setting in step S34 is not detected, the user waits for the user to deliberately press the key operation unit 12. .
[0031]
In step S40, when the key operation unit 12 is pressed, the backlight 29 is turned on for a predetermined number of seconds.
In step S41, the user confirms the message displayed on the transmissive LCD 11, and proceeds to step S38.
As described above, conventionally, unless the user intentionally turns on the backlight 29, the message displayed at the time of the missed call cannot be confirmed. However, the backlight 29 of the transmissive LCD 11 is used for the present invention. By controlling the lighting of the timer, it is no longer necessary for the user to press the key operation unit 12 only for confirmation of the display screen.
[0032]
That is, when a message such as a missed call is displayed on the display screen of the transmissive LCD 11, the backlight 29 can be turned on at a constant cycle, so that the user can easily notice the display message and check the contents. Can do.
Furthermore, it is set so that the message content of the received mail can be automatically displayed on the display screen of the transmissive LCD 11, and the name of the other party who is calling the missed call is not “Missed call” When the user has set the phone number to display, the backlight 29 of the transmissive LCD 11 can be turned on to directly check the display contents.
[0033]
Since the backlight 29 is automatically turned on when necessary, normally, the backlight 29 can be turned off to reduce the battery consumption of the mobile phone.
Next, the backlight timer control unit 21 </ b> A may specify the lighting time zone in addition to the lighting time interval and lighting time of the backlight 29 and store the lighting time zone in the memory unit 25.
[0034]
In this way, it is possible to perform intermittent lighting of the backlight 29 and confirm missed calls only during scheduled times of important incoming calls, for example, in the morning and afternoon. Battery consumption can be reduced.
Further, in addition to the above example, the lighting day and day of the week may be designated and stored in the memory unit 25.
[0035]
In this way, the backlight 29 can be turned on and off only on the scheduled date of important incoming calls, and missed incoming calls can be confirmed, further reducing battery consumption. .
Further, the sounder 16 may be sounded while the backlight 29 is turned on. As a result, when the transmissive LCD 11 of the foldable mobile phone 10 is not viewed, the missed incoming call can be confirmed toward the transmissive LCD 11.
The message confirmation displayed on the transmissive LCD 11 at the time of a missed call has been described above. In addition to this content, this timer function can be used as follows to confirm the current time and the like. Is possible.
[0036]
FIG. 4 is a flowchart for explaining another example of the control operation in FIG.
In step S <b> 41, the user uses the key operation unit 12 to set a timer for lighting the backlight 29, “how many seconds and how many seconds from the current time”. The setting and the set time interval / lighting time are stored in the memory unit 25.
[0037]
In step S42, a timer control start request is made by pressing the key operation unit 12.
In step S43, the backlight timer control unit 21A detects time data input at any time by the clock unit 24 as to whether the set time interval has elapsed from the time set by the timer, and monitors whether the set time interval has passed. To do.
[0038]
In step S44, when the set time interval has elapsed, the backlight 29 is turned on for the set number of seconds.
In step S45, after the backlight 29 is turned on for a set number of seconds, the backlight 29 is turned off.
In step S46, it is monitored again whether the set time interval has elapsed after the backlight 29 is turned off.
[0039]
In step S47, when the set time interval has elapsed, the backlight 29 is turned on for the set number of seconds.
If it is determined in step S48 that the key operation unit 12 is not pressed to stop the timer control, the process returns to step S44, the above steps are repeated, and the backlight 29 is turned on and off. If there is the above request, the timer control is stopped and the process is terminated.
[0040]
With this function, once the timer control is started, the backlight 29 is automatically turned on and off periodically at a certain period of time without intentionally depressing the key operation unit 12. The information content displayed on the transmissive LCD 11 can be confirmed from the antenna bar, the remaining battery level, the image set by the user on the standby screen, and the like.
[0041]
The foldable mobile phone 10 has been described above, but the present invention can also be applied to a mobile phone having an integrated transmissive LCD and a PDA (personal digital assistant).
In the case of a mobile phone having a transflective LCD, the same effects as described above can be obtained in a dark room without night light, at night, or the like.
[0042]
【The invention's effect】
As described above, according to the present invention, the backlight lighting time interval and the lighting time are stored, and after the backlight is turned off, the backlight is turned on for the lighting time interval after the lighting time interval elapses. Since the intermittent display is performed, it is possible to easily confirm the display contents when the backlight is turned off while reducing battery consumption.
In addition, the incoming message for missed calls is displayed on the transmissive LCD when the backlight is intermittently lit, so you can easily check incoming messages for missed calls when the backlight is turned off while reducing battery consumption. become.
[0043]
In addition, when the backlight is turned on and off, the transmissive LCD displays the date and time, antenna bar, remaining battery power, and the image set by the user on the standby screen. It is possible to provide information on the date and time, antenna bar, remaining battery power, and images set by the user on the standby screen on the LCD.
