Abstract

A first information indication is removed from a display screen of a liquid crystal display device, when a screen size display mode is switched into a full-screen display mode where only second information is displayed on the display screen. When a notification mode for notifying the first information by using a notification unit is selected/set by operating a key unit, this first information is notified by employing a light-emitting diode for notifying a message reception, an LCD back light, a KEY back light; or a vibrator.

Claims

1. A mobile communication terminal comprising:

a display for displaying first information indicating a condition of the mobile communication terminal and second information containing at least one of character information and image information in a first display mode, the display for displaying the second information in a full screen size in a second display mode;

a notification unit for notifying the first information; and

a notification unit controller for controlling the notification unit to notify the first information when a present display mode is switched to the second display mode.

2. The mobile communication terminal as claimed in

claim 1

, wherein the first information contains at least one of an electric field strength and a battery energy remaining amount.

3. The mobile communication terminal as claimed in

claim 1

, wherein the notification unit is a light-emitting diode for notifying a call reception;

and

the notification unit controller controls the notification unit to notify the first information based on a turn-ON condition of the light-emitting diode.

4. The mobile communication terminal as claimed in

claim 3

, wherein the notification unit controller controls the notification unit to notify the first information by a turn-ON color or turn-ON period of the light-emitting diode, or a combination of the turn-ON color and the turn-ON period of the light-emitting diode.

5. The mobile communication terminal as claimed in

claim 1

, wherein the notification unit is a back light of the display device;

and

the notification unit controller controls the notification unit to notify the first information using a turn-ON color of the back light.

6. The mobile communication terminal as claimed in

claim 1

, wherein the notification unit is a back light of an operation key;

and

the notification unit controller controls the notification unit to notify the first information using a turn-ON color of the back light.

7. The mobile communication terminal as claimed in

claim 1

, wherein the notification unit is a vibrator for notifying a call reception;

and

the notification unit controller controls the vibrator to notify the first information by a vibration mode of the vibrator.

8. The mobile communication terminal as claimed in

claim 1

, wherein the notification unit comprises at least two notification units;

and

the notification unit controller controls the two notification units to notify the first information by combining notification modes of the two notification units.

9. The mobile communication terminal as claimed in

claim 1

, wherein:

the notification unit controller comprises a setting section for selectively setting a notification mode in which the notification unit notifies the first information when the present display mode is switched to the second display mode; and

when the notification mode is set by the setting section, the notification control unit controls the notification unit to notify the first information under such a condition that the present display mode is switched to the second display mode.

10. The mobile communication terminal as claimed in

claim 9

, wherein:

the setting section sets the notification mode under an idle state; and

the notification control unit controls the notification unit to notify the first information when the present display mode is switched to the second display mode.

11. The mobile communication terminal as claimed in

claim 9

, wherein the setting section sets the notification mode when the present display mode is switched to the second display mode;

and

the notification unit notifies the first information in response to the notification mode set by the setting section.

12. The mobile communication terminal as claimed in

claim 1

, wherein the notification control unit comprises a judging section for judging whether a present state corresponds to an idle state or a telephone communication state;

and

when the judging sections judges that the present state corresponds to the telephone communication state, the notification control unit controls the notification unit to notify the first information when the present display mode is switched to the second display mode.

13. An information display method of a mobile communication terminal having a display for displaying first information indicating a condition of the mobile communication terminal and second information containing at least one of character information and image information in a first display mode, the display for displaying the second information in a full screen size in a second display mode, the information display method comprising:

switching a present display mode to the second display mode; and

notifying the first information by an notification unit.

14. The information display method as claimed in

claim 13

, wherein the first information corresponds to information containing at least one of an electric field strength and a battery energy remaining amount;

and

the second information corresponds to information containing at least character information and image information.

15. The information display method as claimed in

claim 13

, wherein the notification unit comprises at least two notification units;

and

the two notification units notify the first information by combining notification modes of the at least two notification units.

16. The information display method as claimed in

claim 13

, further comprising:

selectively setting, under an idle state, a notification mode in which the first information is notified by the notification unit; and

notifying the first information by the notification unit when the present display mode is switched to the second display mode, while the notification mode is set.

17. The information display method as claimed in

claim 13

, further comprising:

setting a notification mode in which the first information is notified by the notification unit, when the present display mode is switched to the second display mode; and

notifying the first information by the notification unit in response to the setting of the notification mode.

18. The information display method as claimed in

claim 13

further comprising:

judging whether a present state corresponds to an idle state or a telephone communication state; and

notifying the first information by the notification unit when the present display mode is switched to the second display mode under the telephone communication state.
