Abstract

A state of a mobile station is changed from active state 240 when a variety of information is displayed, to standby state 280 in a case that a manipulation by a user or an event such as an incoming call from a mobile packet communication network or a mobile telephone network does not occur for a certain period. In standby state 280, voltage is not applied to a liquid crystal display, and thereby a user sees that a display screen is black.

Claims

1. A mobile communication terminal comprising:

a display means for displaying images;

an information acquisition means for acquiring information through a mobile communication network;

a determination means for determining whether or not the mobile communication terminal is in use; and

a display control means for controlling said display means so as to not display information acquired by said information acquisition means in a case that said determination means determines that the mobile communication terminal is not in use, and controlling said display means to display information acquired by said information acquisition means in a case that said determination means determines that the mobile communication terminal is in use.

2. A mobile communication terminal according to claim 1,

wherein said information acquisition means acquires said information proactively, in compliance with predetermined conditions without manipulation by a user.

3. A mobile communication terminal according to claim 2,

wherein said information acquisition means has access to a server periodically by way of said mobile communication network, and acquires information stored in the server.

4. A mobile communication terminal according to claim 2,

wherein said information acquisition means has access to a server by way of said mobile communication network in compliance with predetermined process conditions, and acquires from the server, information indicating a process result of an operation between the server and the mobile communication terminal.

5. A mobile communication terminal according to claim 2,

wherein said information acquisition means acquires information to be displayed on said display means by extracting a part of information from information transmitted to the mobile communication terminal by a server by way of said mobile communication network, the part of information corresponding to predetermined extraction conditions.

6. A mobile communication terminal according to claim 1,

wherein said determination means determines that the mobile communication terminal is not in use in a case that manipulation by a user does not occur for a certain period.

7. A mobile communication terminal according to claim 1,

wherein said determination means determines that the mobile communication terminal is not in use in a case that an information signal is not transmitted for a certain period, the information signal being transmitted from an external device to the mobile communication terminal.

8. A mobile communication terminal according to claim 1,

wherein said display means displays images by applying a voltage controlled by said display control means, and said display control means does not apply the voltage between electrodes corresponding to the whole display area of said display means in a case that said determination means determines that the mobile communication terminal is not in use.

9. A mobile communication terminal according to claim 1,

wherein said display means displays images by applying a voltage controlled by said display control means, and said display control means controls the display of all information except for information acquired by said information acquisition means, and said display control means does not apply a voltage between electrodes corresponding to a part of a display area of said display means, but applies a voltage between electrodes corresponding to a remaining part of a display area of said display means.
