In addition, the organic EL display is an organic EL element as an electro-optical element arranged in a matrix, and the organic EL element emits light and becomes visible, so that a backlight is not required and the device is a low power consumption device. Although it is used, light emission corresponding to the displayed area may be performed, and power consumption decreases when the display area is smaller.

The sub display unit 109 can display a plurality of display items under the control of the control unit 111. The sub-display unit 109 displays a first pattern that displays all display items, a second pattern that displays some of the display items, and a third pattern that does not display display items and that does not display. Each time the key 110 is pressed, the display is switched cyclically.
In the first pattern displayed on the sub display unit 109, a time display area for displaying time, a calendar display area for displaying date and time, and a state display area for the mobile phone 100 are displayed using the entire display area. 4 includes a pattern indicated by A.
Further, as the second pattern, the clock display area having the largest area among the display areas indicated by A is turned off, and the calendar display area used in the calendar is replaced with the calendar and the mobile phone 100 is used. 4 is provided, and a pattern as shown by B in FIG. 4 is provided in which a partially unused area is provided in which the display of the state display area of the mobile phone 100 is continued. Further, the second pattern is an enlarged view of a partially unused area in which the calendar display area is further turned off from the pattern B in FIG. 4 and the state display area of the mobile phone 100 is continuously displayed. A pattern as indicated by C in 4 is also included.
The third pattern includes a pattern as indicated by D in FIG. 4 in which the state display area of the mobile phone 100 is further turned off from the pattern C in FIG. 4 and all display areas are turned off.

The display of the sub display unit 109 is switched every time the back key 110 is pressed. When the patterns shown in FIGS. 4A to 4D are displayed, the back key 110 is pressed for a predetermined time, for example, 10 seconds ( If the operation is not performed, it is forcibly turned off as a timeout under the control of the control unit 111 (transition to a state without display).
The sub-display unit 109 is turned on so as to display with the first pattern when the detection signal S106 of the open / close detection unit 106 is newly detected, for example, after being forcibly turned off as a timeout (transition to a state without display). Is done. If the sub display unit 109 times out and forcibly turns off when the first casing 112 and the second casing 113 are closed, the sub-display unit 109 is once opened and then closed again. When the state is set, the input of the detection signal S106 can be newly detected, so that the sub-display unit 109 is controlled to be turned on so as to display with the first pattern.

The back key 110 is controlled to be valid / invalid by the control unit 111, and when it is controlled as valid, the display state (display pattern) on the sub display unit 109 as shown in FIG. 4 can be designated by pressing the key. It is.
The back key 110 can be input by the first input pattern and the second input pattern.
The first input pattern is an input pattern for designating a display state in the sub display unit 109 as shown in FIG. 4 by a key depression operation, and a display pattern is designated by a normal key depression (short time depression).
The second input pattern is an input pattern in which the key pressing time is long according to the first input pattern, for example, an input pattern in which the back key 110 is pressed long (for example, 2 seconds or more).
When the back key 110 is pressed down for a long time, the control unit 111 sets a key flag to validate the input of the back key 110.
In addition, when the display state of the first pattern, the second pattern, or the third pattern displayed on the sub display unit 109 due to a time-out is changed and the display is forcibly changed to the off state (no display state) When the back key 110 is pressed for a long time, the sub-display unit 109 controls the control unit 111 to control the first pattern, that is, the calendar display indicating the time and date as shown by A in FIG. The lighting is controlled so as to display with a pattern including the status display.

The control unit 111 is configured mainly with a microcomputer, and controls the entire mobile phone 100.
For example, the control unit 111 controls transmission / reception of various types of information in the communication processing unit 102, imaging control of the imaging unit 105 by the second control signal CTL2, and audio information for the audio processing unit 108 by the first control signal CTL1. Processing, information display and lighting control on the main display unit 107, lighting display control on the sub display unit 109, processing according to input information of the key input unit 104, access control to the memory 103, and the like are performed.

For example, when the detection signal S106 of the open / close detection unit 106 indicates that the first casing 112 and the second casing 113 are in the open state, the control unit 111 enters the wireless communication mode and performs main display. The lighting of the unit 107 and display control are performed. At this time, the control unit 111 controls the sub display unit 109 to be turned off.
The wireless communication mode is a mode in which wireless communication is possible through the communication processing unit 102, and the control unit 111 causes the display unit 117 to display a standard screen (so-called standby screen) immediately after power activation. In the wireless communication mode, a call operation or the like can be performed by operating the key input unit 104.

When the back key 110 is not pressed for a long time and the key flag is not set, the control unit 111 controls the sub display unit 109 to be turned off and does not accept the input of the back key 110.
When the back key 110 is pressed for a long time, the control unit 111 sets a key flag and controls the sub display unit 109 to light up. First, the sub display unit 109 has a first pattern (A in FIG. 4). The display is controlled with a pattern, and while the key flag is set, the input of the back key 110 is accepted as valid.

When the back key 110 is pressed within 10 seconds from the display of the first pattern of the back key 110 in a state where the key flag is set, the control unit 111 sets the second pattern (pattern B in FIG. 4). When the back key 110 is pressed within 10 seconds after the back key 110 is pressed to display the second pattern, another second pattern (pattern C in FIG. 4) is displayed. When the back key 110 is pressed within 10 seconds after the back key 110 is pressed to display the second pattern, the display is switched to the display of the third pattern (pattern D in FIG. 4). If the back key 110 is pressed within 10 seconds after the back key 110 is pressed to display the pattern 3, the display is switched to the display of the first pattern (pattern A in FIG. 4).
That is, when the key flag is set and the rear key 110 is pressed within 10 seconds after the first pattern is displayed on the sub display unit 109, the control unit 111 displays 4 of A to D shown in FIG. One pattern is displayed cyclically.

When the key flag is set and each pattern shown in FIG. 4A to FIG. 4D is displayed on the sub display unit 109 every time the back key 110 is pressed, the control unit 111 has a predetermined time, for example, 10 If the back key 110 is not pressed (operated) for more than one second, the key flag is reset as a timeout and forcibly turned off (transition to a state without display).
After the control unit 111 thus forcibly turns off the sub-display unit 109 as a timeout in this way (transitions to a state without display), for example, the first casing 112 and the second casing 113 are in a closed state. When the detection signal S106 of the open / close detection unit 106 indicating that is input, the lighting control is performed so that the key flag is set and the first pattern is displayed.
That is, when the control unit 111 finishes the processing of the wireless communication mode and is closed so that the first housing 112 and the second housing 113 are turned on, the control unit 111 sets the key flag and sets the sub display unit. 109 is displayed with a first pattern including a calendar display.

  Next, the operation of the mobile phone according to the present embodiment will be described with reference to the flowcharts of FIGS. 4 and 5, focusing on the control of the sub display unit and the back key.

If the user opens the first casing 112 and the second casing 113 that are in a closed state in order to make a call or mail transfer, the detection signal S106 is not input from the opening / closing detection unit 106. The controller 111 determines that the housing 112 and the second housing 113 are in the open state.
Accordingly, the control unit 111 enters the wireless communication mode and performs lighting and display control of the main display unit 107. At this time, the control unit 111 controls the sub display unit 109 to be turned off.
In the wireless communication mode, the control unit 111 causes the display unit 117 to display a standard screen immediately after power activation (so-called standby screen), and a call operation or the like is performed by the user's operation of the key input unit 104.

When the processing desired by the user is finished and the first casing 112 and the second casing 113 in the open state are closed, the first casing 112 and the second casing 113 are opened from the open / close detection unit 106. A detection signal S106 indicating that is closed is input to the control unit 111.
The control unit 111 that has received the detection signal S106 ends the process of the wireless communication mode, and first sets the key flag to be closed so that the first casing 112 and the second casing 113 are in contact with each other. The sub-display unit 109 displays the first pattern including the calendar display.
At this time, if the user puts the mobile phone 100 in the bag or pocket without operating the back key 110, the back key 110 is not pressed (operated) for more than 10 seconds with the first input pattern. The unit 111 resets the key flag and causes the sub display unit 109 to transition to the unlit state as a timeout.

Here, when the user takes out the mobile phone 100 from the bag or pocket and confirms the display on the sub display unit 109, first, the sub display unit 109 is controlled to be in a non-display state (light-off state) ( ST1) Long press the back key 110.
Since the back key 110 has been pressed for a long time, the control unit 111 sets a key flag. If the back key 110 is pressed within 10 seconds from the display of the first pattern of the back key 110 in FIG. 4 while the key flag is set, the control unit 111 displays the pattern of FIG. 4B. Switch.
Similarly, when the back key 110 is pressed within 10 seconds after the back key 110 is pressed to display the pattern of FIG. 4B, the display switches to the pattern of FIG. 4C and the pattern of FIG. 4C is displayed. When the back key 110 is pressed within 10 seconds after the back key 110 is pressed, the display is switched to the pattern shown in FIG. 4D, and within 10 seconds after the back key 110 is pressed to display the pattern of FIG. 4D. When the back key 110 is pressed, the display is switched to the pattern shown in FIG. 4A (ST3, ST4).

  When the key flag is set and each pattern shown in FIGS. 4A to 4D is displayed on the sub display unit 109 every time the back key 110 is pressed, the control unit 111 keeps the back for 10 seconds or more. If the key 110 is not pressed (operated), the key flag is reset as a timeout and forcibly turned off (transition to a state without display) (ST5).

As described above, in the present embodiment, when the first casing 112 and the second casing 113 are closed, the key flag is set and the sub display unit 109 is temporarily displayed in a predetermined pattern. If there is no operation of the rear key 110 for designating display of a predetermined pattern on the sub-display unit 109 for 10 seconds or more, the key flag is forcibly reset and the key flag is reset as a timeout and forcibly turned off (the display is turned off). Therefore, there is an advantage that efficient display control corresponding to low power consumption can be performed and the light emission time can be shortened.
For example, even if the switch is pushed without permission when it is put in the bag in a closed state, the key flag is forcibly reset if the back key 110 is not operated for 10 seconds or longer. As a timeout, the key flag is reset to forcibly turn off, and the state of no display is maintained unless a long press or a detection signal S106 is newly detected. Time can be shortened.
In particular, when a self-light-emitting organic EL display is used for the sub display unit, the EL itself emits light compared to the liquid crystal, which increases power consumption. Electricity can be realized.
Moreover, although organic EL has a lifetime, since the light emission time can be as short as possible, the lifetime of the display element can be extended.
