Abstract

A mobile terminal equipped with a flexible first display module and a second display module capable of receiving a touch input and a method of controlling the mobile terminal are provided. The method includes displaying an operating screen on the first display module and displaying an operation control menu on the second display module; determining whether the first display module is bent or folded; and choosing one of a plurality of menu items of the operation control menu corresponding to a bent or folded portion of the first display module. Therefore, it is possible to control various operations performed by the mobile terminal according to whether the first display module is bent or folded.

a second display module configured to receive a touch input and to display an operation control menu including a plurality of menu items;

a sensing unit operatively connected to the first display module and configured to determine which portion of the first display module is bent or folded; and

a controller operatively connected to the sensing unit and configured to choose one of the plurality of menu items of the operation control menu corresponding to the bent or folded portion of the first display module determined by the sensing unit.

10. The mobile terminal of claim 9, wherein the controller is configured to control an operation corresponding to the chosen menu item to be performed.

11. The mobile terminal of claim 9, wherein, when a touch input is detected in an area where the chosen menu item is displayed, the controller is configured to control an operation to be performed corresponding to the chosen menu item.

12. The mobile terminal of claim 9, wherein the controller is configured to display an inquiry message and to decide whether or not to perform an operation corresponding to the chosen menu item according to a reply to the inquiry message.

13. The mobile terminal of claim 9, wherein the second display module is disposed on a level with the first display module and connected to the first display module.

14. A method of controlling a mobile terminal equipped with a flexible first display module and a second display module capable of receiving a touch input, the method comprising:

displaying an operating screen corresponding to a current operating mode on the first display module; and

displaying on the second display module an operation control menu, including a plurality of menu items, that can be executed in the current operating mode when the first display module is bent or folded.

15. The method of claim 14, further comprising:

when one of a plurality of menu items of the operation control menu is touched, performing an operation corresponding to the chosen menu item.

16. A mobile terminal, comprising:
