Abstract

An object of the present invention is to reduce current consumption of the overall device containing a display portion in the communication mode.

In the present invention, a control portion (18) of a mobile radio device outputs a control signal to an LCD driving portion (19) to drive an LCD (15) and to execute display control. When the device is in a communication mode by a radio communication portion (17), a mode display is executed in a background that has a color of a turn-OFF mode by using a color of a turn-ON mode on the display screen of the LCD (15), for example, the modes display such as “talking”, or the like is executed in the background in black color by characters in white color. Also, a partial display is executed such that a display only in an area in which the mode display is executed is turned ON and the display in other areas is turned OFF. Accordingly, the current consumption of the LCD (15) can be reduced.

Claims

1. A mobile radio device comprising:

a radio communication portion for executing communication via radio;

a display portion for displaying an operation mode of the device; and

a control portion for allowing the display portion to execute a mode display by using a color at a time of a turn-ON mode in a background that has a color at a time of a turn-OFF mode, when the device is in a communication mode by the radio communication portion.

2. The mobile radio device according to claim 1, wherein the control portion allows the display portion to execute a mode display by characters in white color indicating the time of the turn-ON mode in the background in black color indicating the time of the turn-OFF mode, when the device is in the communication mode.

3. The mobile radio device according to claim 1, wherein the control portion allows the display portion to execute such a partial display that a display only in an area where the mode display is executed is turned ON, and the display in other areas is turned OFF when the device is in the communication mode.

4. The mobile radio device according to claim 1, further comprising a sensing means for sensing a situation that the device comes close to a user'"'"'s head,

wherein the control portion allows the display portion to turn OFF a display in all or a part of display area in the display portion when approach of the head is sensed by the sensing means.
