Abstract

A method and device for controlling the scrolling of pages on a touch screen of a hand-held electronic apparatus. A liquid crystal display and a touch panel having a larger area than that of the liquid crystal display are overlapped and combined with each other. The overlapped region is defined as a first touch zone, while the non-overlapped region is defined as second touch zones and a third touch zone. Next, a user determines whether a scroll is shown in the picture of the display. If the user determines that a scroll is shown in the picture, a sliding path is sensed by the second touch zone, and the user controls the page to scroll upwards or downwards in the picture based on the sliding path. The first touch zone is pressed to thereby perform the function of the selected page. If the user determines that a scroll is not shown in the picture, a sliding path is sensed by the third touch zone, and the user controls the page to slide rightwards or leftwards in the picture based on the sliding path. The first touch zone is pressed again to thereby perform the function of the selected page.

Claims

1. A method for controlling scrolling of pages (4) on a touch screen of a hand-held electronic apparatus (1), the hand-held electronic apparatus (1) having a liquid crystal display (2) and a touch panel (3) with a larger area than that of the liquid crystal display (2), a region of the touch panel (3) overlapped by the liquid crystal display (2) being a square first touch zone (31), left and right portions of a region of the touch panel (3) not overlapped by the liquid crystal display (2) being defined as second touch zones (32, 32′

), a lower portion of a region of the touch panel (3) not overlapped by the liquid crystal display (2) being defined as a third touch zone (33), the method comprising the steps of;

a) determining whether a scroll (6) is shown in a picture on the display (2);

b) sensing a sliding path and direction from a starting coordinate to an ending coordinate on the second touch zone (32, 32′

) if a scroll (6) is shown on the picture of the display (2), controlling a sensed scrolling state of the page (4) on the picture of the display (2) based on the sliding path and direction; and

c) sensing a sliding path and direction from a starting coordinate to an ending coordinate on the third touch zone (33) if the scroll (6) is not shown on the picture of the display (2), controlling a sensed sliding state of the page (4) on the picture of the display (2) based on the sliding path and direction.

2. The method according to claim 1, wherein the sensed scrolling state of the page (4) on the picture of the display (2) is to slide upwards when the sliding path sensed by the second touch zone (32, 32′

) in the step b) is from bottom to top.

3. The method according to claim 1, wherein the sensed scrolling state of the page (4) on the picture of the display (2) is to slide downwards when the sliding path sensed by the second touch zone (32, 32′

) in the step b) is from top to bottom.

4. The method according to claim 1, wherein after a page (4) is selected in the step b), the first touch zone (31) is pressed to thereby perform the function of the selected page (4).

5. The method according to claim 1, wherein the page (4) is sensed to slide rightwards on the picture of the display (2) when the sliding path sensed by the third touch zone (33) in the step c) is from left to right.

6. The method according to claim 1, wherein the page (4) is sensed to slide leftwards on the picture of the display (2) when the sliding path sensed by the third touch zone (33) in the step c) is from right to left.

7. The method according to claim 1, wherein after a page (4) is selected in the step c), the first touch zone (31) is pressed to thereby perform the function of the selected page (4).

8. The method according to claim 1, wherein the pages (4) in the step c) are arranged in a circle, the pages (4) rotate clockwise when a sliding path sensed by the third touch zone (33) is from left to right, the selected page (4) is displayed on the most top layer, after a desired page (4) is selected, the first touch zone (31) is pressed to thereby perform the function of the selected page (4).

9. The method according to claim 8, wherein the pages (4) rotate counterclockwise when a sliding path sensed by the third touch zone (33) is from right to left, the selected page (4) is displayed on the most top layer, after a desired page (4) is selected, the first touch zone (31) is pressed to thereby perform the function of the selected page (4).

10. The method according to claim 1, wherein the pages (4) in the step c) are arranged as a half-opened book, each page (4) turns rightwards like turning pages of the book when a sliding path sensed by the third touch zone (33) is from left to right, the selected page (4) is stopped in the center of the screen, and the first touch zone (31) is pressed at this time to thereby perform the function of the selected page (4).

11. The method according to claim 10, wherein each page (4) turns leftwards like turning pages of the book when a sliding path sensed by the third touch zone (33) is from right to left, the selected page (4) is stopped in the center of the screen, and the first touch zone (31) is pressed at this time to thereby perform the function of the selected page (4).

12. The method according to claim 10, wherein a built-in system drives a speaker to generate a sound effect when scrolling or switching each page (4) in the operations of step c) and step b).

13. A device for controlling scrolling of pages (4) on a touch screen of a hand-held electronic apparatus (1), comprising:

a display (2);

a touch panel (3) provided on the surface of the display (2), a region of the display (2) corresponding to the touch panel (3) being defined as a first touch zone (31), the periphery of the first touch zone (31) being defined as second and third touch zones (32, 32′

, 33);

wherein the second and third touch zones (32, 32′

, 33) of the touch panel (3) are used to sense a sliding path in operation and then control the scrolling of the pages (4) on the display (2) based on the sliding path.

14. The device for controlling the scrolling of pages (4) on a touch screen of a hand-held electronic apparatus (1) according to claim 13, wherein marginal lines of the first touch zone (31) are defined as borders (311) between the first touch zone (31) and the second and third touch zones (32, 32′

, 33).
