Patent Images
1. A method of reducing power consumption in a mobile terminal having a first display module and a second display module, the method comprising:
- displaying content of a first web page in a color mode in the first display module;
determining a remaining battery power of the mobile terminal;
disabling the first display module and displaying content of a second web page in a black-and-white mode in the second display module in response to determining that the remaining battery power is less than a reference battery power, wherein the displayed content of the second web page is the same as at least some of the displayed content of the first web page and comprises text included in the first web page without an image included in the first web page;
displaying a message in the second display module in response to determining that the remaining battery power is less than the reference battery power, wherein the displayed message comprises a first indication that the second display module is used instead of the first display module;
maintaining the display of the content of the first web page in the first display module and displaying a result screen in a black-and-white mode in the second display module in response to determining that the remaining battery power exceeds the reference battery power, wherein the result screen is obtained via a search performed via the displayed first web page; and
performing functions of a double-sided display using the first and second display modules,wherein;
the first display module is disposed on a front side of a main body of the mobile terminal;
the second display module is disposed on a rear side of the main body; and
the first and second display modules form a symmetrical structure and face opposite directions from each other.
