BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal, and in particular, to provide a power saving mode function for displaying only a partial display area of a liquid crystal screen of a mobile communication terminal by a user's selection, thereby reducing power consumption of the mobile communication terminal. It relates to a control method.

In a mobile communication terminal such as a mobile phone using a battery having a predetermined capacity, the time that can be used to charge the battery once reaches tens of hours in total talk time and standby time. However, if the terminal can be used for as long as possible with a single charge of a battery with the same capacity, the device can be used for a period of time (typically 1 to 3 days) that meets the customer's needs with a single charge even if the battery capacity is reduced. can do. In this case, even when a battery having a smaller capacity than that of the existing terminal is used, tens of hours of use of the terminal can be secured. Therefore, the weight and size of the terminal can be reduced, and the thickness can be reduced. As a result, it will be easier for the user to carry the terminal. However, due to the rapid development of today's technology, the power consumption of mobile terminals currently used has reached a considerably small state, and thus, there is a limit in reducing power consumption in hardware. By controlling, the power consumption of the terminal can be somewhat reduced.

However, in the conventional mobile communication terminal, since the front of the display unit is always in the display state except when the folder is closed, unnecessary power is not provided if the user does not need the display front display. There is a problem of exhaustion. In addition, when the liquid crystal display of the terminal is a color liquid crystal display, there is a problem that more power is consumed.

Accordingly, the present invention has been proposed to solve the above-described problems of the prior art, and provides a power saving mode function for displaying only a partial display area of a liquid crystal screen of a mobile communication terminal by a user's selection, thereby improving battery life. Its purpose is to lengthen it.
