Abstract
Disclosed herein are an apparatus and a method for scrolling a screen of a portable terminal with a touch screen, which is able to scroll the screen by a desired distance by one touch operation. When user touch is detected in screen scroll command areas, a touch position and time sensor calculates and applies a touch position and time of a user to a scroll direction and distance calculator. The scroll direction and distance calculator calculates and applies a scroll direction and distance of the screen based on the touch position and time received from the touch position and time sensor to a screen scrolling unit. The screen scrolling unit scrolls the screen based on the scroll direction and distance received from the scroll direction and distance calculator. By this configuration, it is possible to scroll the screen by a distance desired by the user by one touch operation and prevent a muscle of a finger or wrist, a ligament of a joint or a fingerprint from being damaged.
