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.
