Abstract

A method and apparatus for facilitating scrolling of items on a display screen of an electronic device are provided. A first number of scrollable items representing a portion of a set of displayable items are displayed on the display screen. An input command for performing an “easy scroll function” is then detected. In response to the detected input command, the display screen is divided into a predetermined number of divided display screens, each independently scrollable and each displaying a respective number of items of the set of items, according to a display setting therefor. Each divided display screen may display a different number of items and may be scrollable at a different rate.

Claims

1. A method for scrolling items on a display screen in an electronic device, the method comprising:

displaying on the display screen a first number of scrollable items representing a portion of a set of displayable items;

detecting an input command for performing an easy scroll function on the display screen; and

responsive to the detected input command, dividing the display screen into a predetermined number of divided display screens, each independently scrollable and each displaying a respective number of items of the set of items, according to a display setting therefor.

2. The method as claimed in claim 1, wherein the input command is a scroll input on a preset area of the display screen on which the items are displayed.

3. The method as claimed in claim 2, wherein the preset area corresponds to a left side of the display screen when items are scrollable vertically on the display screen.

4. The method as claimed in claim 3, further comprising, prior to detecting the input command, scrolling the items on the display screen in response to an entered scroll input, when the scroll input is entered on a right side of the display screen.

5. The method as claimed in claim 1, wherein the divided display screens comprise a first divided display screen in which the same first number of items are displayed, and at least one second divided display screen in which a higher number of items are displayed.

6. The method as claimed in claim 5, wherein a scroll input gesture applied to the second divided display screen results in a higher rate of scroll than the same scroll input gesture applied to the first divided display screen.

7. The method as claimed in claim 1, wherein first and second divided display screens of the predetermined number of divided display screens each display at least one common item when the divided display screens are generated.

8. The method as claimed in claim 1, wherein the predetermined number of divided display screens is an integer N of at least two, and further comprising re-dividing the display screen into N+1 divided display screens, when a request for performing the easy scroll function is made on any one of the N divided display screens.

9. The method as claimed in claim 8, wherein the input command for performing an easy scroll function on the display screen is a scroll input on a preset area of the display screen on which the items are displayed, and the request for performing the easy scroll function made on any one of the N divided display screens is a scroll input entered in a preset area of that divided display screen.

10. The method as claimed in claim 9, wherein the preset area of the divided display screen is an area corresponding to a left part thereof when the items are scrollable vertically.

11. A non-transitory recording medium storing computer-executable instructions for performing the method of claim 1.

12. An apparatus for displaying and scrolling items, the apparatus comprising:

a display unit controllable to display on a display screen a first number of scrollable items representing a portion of a set of displayable items; and

a controller coupled to the display unit and configured to detect an input command for performing an easy scroll function on the display screen, and responsive to the detected input command, to control dividing of the display screen into a predetermined number of divided display screens, each independently scrollable and each displaying a respective number of items of the set of items, according to a display setting therefor.

13. The apparatus as claimed in claim 12, wherein the input command for performing an easy scroll function is a scroll input in a preset area of the display screen, on which the items are displayed.

14. The apparatus as claimed in claim 13, wherein the preset area corresponds to a left side of the display screen when items are scrollable vertically on the display screen.

15. The apparatus as claimed in claim 14, wherein the controller performs a control operation, prior to detecting the input command, to scroll the items on the display screen in response to a scroll input entered on a right side of the display screen.

16. The apparatus as claimed in claim 12, wherein the divided display screens comprise a first divided display screen in which the same first number of items are displayed, and at least one second divided display screen in which a higher number of items are displayed.

17. The apparatus as claimed in claim 12, wherein the predetermined number of divided display screens is an integer N of at least two, and the controller performs a control operation to re-divide the display screen into N+1 divided display screens, when a request for performing the easy scroll function is made on any one of the N divided display screens.

18. The apparatus as claimed in claim 17, wherein the input command for performing an easy scroll function on the display screen is a scroll input on a preset area of the display screen on which the items are displayed, and the request for performing the easy scroll function made on any one of the N divided display screens is a scroll input entered in a preset area of that divided display screen.

20. A portable electronic device comprising:

a touch screen display unit controlled to display on a display screen a first number of scrollable items representing a portion of a set of displayable items; and

a controller coupled to the display unit and configured to detect an input command for performing an easy scroll function, and responsive to the detected input command, to control dividing of the display screen into a predetermined number of divided display screens, each independently scrollable and each displaying a respective number of items of the set of items, according to a display setting therefor.

19. The apparatus as claimed in claim 20, wherein the preset area of the divided display screen is an area corresponding to a left side thereof when the items are scrollable vertically.
