Abstract

A mobile terminal having electronic paper and a method for controlling the same are provided, wherein the mobile terminal comprises: a first display unit configured to implement a role of electronic paper; a second display unit configured to be mounted at one side of the first display unit for implementing a role of a light emitting display unit; a memory configured to store a program for implementing a predetermined menu; and a controller configured to display the menu on the first display unit or the second display unit.

Claims

1. A mobile terminal, comprising:

a first display unit configured to provide a non-light emitting display;

a second display unit mounted at one side of the first display unit and configured to provide a light emitting display as a touch screen;

a memory configured to store a program for implementing a predetermined menu; and

a controller configured to control the first display unit to display the menu on the non-light emitting display or control the second display unit to display the menu on the light emitting display.

2. The mobile terminal of claim 1, wherein the non-light emitting display provided by the first display unit comprises an electronic paper function.

3. The mobile terminal of claim 2, further comprising a plurality of keys located adjacent to the non-light emitting display provided by the first display unit, wherein at least a first of the plurality of keys provides a function related to movement of data displayed by the electronic paper function.

4. The mobile terminal of claim 2, wherein the memory stores E-book data and the controller is further configured to control the first display unit to display a first E-book included in the stored E-book data on the non-light emitting display and to control the second display unit to display second data successive to the first E-book on the light emitting display.

5. The mobile terminal of claim 2, further comprising an input unit configured to receive a user input, wherein:

the memory stores E-book data and

the controller is further configured to control the first display unit to display a first portion of the E-book data on the non-light emitting display and to control the second display unit to display a second portion of the E-book data on the light emitting display when a selection signal received from the user via the input unit.

6. The mobile terminal of claim 3, wherein at least a second of the plurality of keys comprises touch sensors or touch strips.

7. The mobile terminal of claim 3, wherein the function related to movement of data displayed by the electronic paper function comprises a scroll function.

8. The mobile terminal of claim 7, wherein the scroll function comprises page advance of E-book data displayed on the non-light emitting display.

9. The mobile terminal of claim 1, wherein the first display unit includes a monochrome display function and the second display unit includes a color display function.

10. The mobile terminal of claim 1, wherein the memory stores E-book data and the controller is further configured to control the first display unit to display the E-book data on the non-light emitting display.

11. The mobile terminal of claim 1,

wherein the controller is further configured to control the second display unit to display a portion of the menu on the light emitting display when a selection signal is generated during display of the menu on the non-light emitting display.

12. A method for controlling a mobile terminal, comprising:

providing a mobile terminal including a first display unit configured to provide a non-light emitting display, a second display unit configured to provide a light emitting display as a touch screen and a memory configured to store a program for implementing a predetermined menu; and

controlling the first display unit to display the menu on the non-light emitting display or controlling the second display unit to display the menu on the light emitting display.

19. The method of claim 12, wherein the memory stores E-book data and further comprising controlling the first display unit to display the E-book data on the non-light emitting display.

20. The method of claim 12, further comprising controlling the second display unit to display a portion of the menu on the light emitting display when a selection signal is generated during display of the menu on the non-light emitting display.

13. The method of

wherein the non-light emitting display provided by the first display unit comprises an electronic paper function.

14. The method of claim 13, further comprising providing a plurality of keys located adjacent to the non-light emitting display provided by the first display unit, wherein at least a first of the plurality of keys provides a function related to movement of data displayed by the electronic paper function.

15. The method of claim 13, wherein the memory stores E-book data and further comprising:

controlling the first display unit to display a first E-book included in the stored E-book data on the non-light emitting display; and

controlling the second display unit to display second data successive to the first E-book on the light emitting display.

16. The method of claim 13, wherein the memory stores E-book data and further comprising controlling the first display unit to display a first portion of the E-book data on the non-light emitting display and controlling the second display unit to display a second portion of the E-book data on the light emitting display when a selection signal is received from a user.

17. The method of claim 14, wherein the function related to movement of data displayed by the electronic paper function comprises a scroll function.

18. The method of claim 17, wherein the scroll function comprises page advance of E-book data displayed on the non-light emitting display.
