Portable terminal and icon arranging method thereof

1. A portable terminal comprising:

a display module including a main display part and a sub-display part adjacent to the main display part; and

a control module which controls a main image displayed on the main display part and icon groups displayed on the sub-display part,

wherein, when a first icon group among the icon groups is in an active state in which the first icon group is displayed through the sub-display part, a second icon group among the icon groups is controlled to be in an inactive state in which the second icon group is not displayed through the main display part and the sub-display part,

wherein when an external input is detected on the sub-display part, the second icon group is controlled to be in an active state in which the second icon group is displayed through the sub-display part,

wherein the sub-display part comprises a first sub-display part and a second sub-display part spaced apart with the main display part interposed therebetween, and

wherein the first icon group comprises a first sub-icon group displayed on the first sub-display part and a second sub-icon group displayed on the second sub-display part.

2. The portable terminal of claim 1 , wherein when the external input is detected on at least one of the first sub-display part and the second sub-display part, at least one of the first sub-display part and the second sub-display part displays the second icon group.

3. The portable terminal of claim 2 , wherein the second icon group comprises a third sub-icon group and a fourth sub-icon group,

wherein when the external input is detected on at least one of the first sub-display part and the second sub-display part, the third sub-icon group is displayed through the first sub-display part and the fourth sub-icon group is displayed through the second sub-display part.

4. The portable terminal of claim 3 , wherein when the third sub-icon group and the fourth sub-icon group are respectively displayed through the first sub-display part and the second sub-display part, each of the first sub-icon group and the second sub-icon group is switched to the inactive state.

5. The portable terminal of claim 1 , wherein when the external input is detected on the first sub-display part, the second sub-icon group is displayed through the first sub-display part, and the second icon group is displayed through the second sub-display part.

6. The portable terminal of claim 5 , wherein an icon group displayed on the second sub-display part among the icon groups is translucent.

7. The portable terminal of claim 5 , wherein the first sub-icon group is switched to the inactive state.

8. The portable terminal of claim 1 , wherein an area of the main display part is larger than an area of the sub-display part.

9. The portable terminal of claim 1 ,

wherein when a first external input of the external input is detected through the sub-display part, the second icon group is displayed through the sub-display part,

wherein when a second external input of the external input is detected through the sub-display part, a third icon group among the icon groups is displayed through the sub-display part,

wherein when the third icon group is displayed through the sub-display part, the first icon group and the second icon group are switched to the inactive state.

10. The portable terminal of claim 1 ,

wherein when a first external input of the external input is detected through the sub-display part, the second icon group is displayed through the sub-display part,

wherein when a second external input of the external input is detected through the sub-display part, the first icon group is displayed through the sub-display part,

wherein while the first icon group is displayed through the sub-display part by the second external input, the second icon group and the other icon groups of the icon groups are switched to the inactive state.

11. The portable terminal of claim 1 , wherein the first sub-display part extends from one end of the main display part and the second sub-display part extends from the other end of the main display part.

12. The portable terminal of claim 11 , wherein in a plan view, each of the first sub-display part and the second sub-display part has a semicircular shape, and an outline of each of the first sub-display part and the sub-display part has a curve.

13. The portable terminal of claim 1 , wherein the display module further comprises a bezel portion spaced from the main display part and adjacent the sub-display part,

wherein the bezel portion is provided in a curved shape.

14. A portable terminal comprising:

a display module including:

a main display part which displays a main image;

a first sub-display part which displays a first sub-image, and

a second sub-display part which is spaced apart from the first sub-display part with the main display part interposed directly therebetween and displays a second sub-image; and

a control module which outputs to the display module an image signal corresponding to the main image, and a first sub-image signal and a second sub-image signal corresponding to the first sub-image and the second sub-image, respectively,

wherein the display module displays the first sub-image through the first sub-display part and displays the second sub-image through the second sub-display part while the main image is displayed.

15. The portable terminal of claim 14 , wherein the display module further comprises a first bezel portion spaced from the main display part and adjacent the first sub-display part and a second bezel portion adjacent the second sub-display part,

wherein each of the first bezel portion and the second bezel portion is provided in a curved shape.

16. The portable terminal of claim 15 , wherein an area of a central portion of each of the first bezel portion and the second bezel portion is larger than an area of an edge portion, and a camera module and an audio output module are disposed at the central portion.

17. An icon arrangement method of a portable terminal, the method comprising:

displaying a first icon group among a plurality of icon groups through a sub-display part adjacent to a main display part of a display module;

sensing an external input through the sub-display part; and

displaying a second icon group among the icon groups through the sub-display part according to the external input sensed through the sub-display part,

wherein in a case of an active state in which the first icon group is displayed through the sub-display part, the second icon group is in an inactive state in which the second icon group is not displayed through the sub-display part, and

wherein when a first external input of the external input is detected through the sub-display part, the second icon group is displayed through the sub-display part,

wherein when a second external input of the external input is detected through the sub-display part, at least one of the first icon group and a third icon group among the icon groups is displayed through the sub-display part.

18. The method of claim 17 , wherein each of the icon groups comprises at least one icon.
