<p>PURPOSE: A screen scroll method of a display device and a device thereof are provided to offer a list scroll without a touch at a portable terminal using a touch input with a display for using a screen without covering the screen. CONSTITUTION: A screen scroll is initiated according to the speed of a flick input when the flick input is generated (606). Variation of the gradient according to one set axis of a device compared with the initial position at the generation of the flick input is determined (608). If the variation deviates from a reference value, present screen scroll speed is maintained (620). If a set scroll pause condition is generated, a screen scroll action is stopped (614). An operation varying scroll speed according to the gradient variation of the device when maintaining the present screen scroll speed. [Reference numerals] (602) Confirm a flick input; (604) Check the speed of the flick input (code, speed); (606) Initiate a screen scroll according to the speed of the flick input; (608) Is the gradient according to one set axis of a device coming within a reference range ?; (610) Reduce the speed of the screen scroll; (612) Is the speed of a touch input or the screen scroll zero ?; (614) Stop the screen scroll; (620) Maintain the speed of the screen scroll (change the scroll speed according to changes in the gradient); (630) Are a set of conditions for stopping the scroll satisfied ?; (AA) List view display; (BB) Is there a flick input ?; (CC,EE,GG,II) No; (DD,FF,HH,JJ) Yes; (KK) End</p> |
