Abstract
A mobile terminal and method for controlling a touch screen thereof are provided, wherein multi-point touch inputs such as a multi-point sweep input and/or a multi-point double tap input are sensed by a controller, and in response to a multi-point sweep, a display screen can be scrolled at a faster rate relative to a scroll in response to sensing a single point sweep, thus enabling a user to rapidly scroll to desired portions of an information screen using e.g., a two finger sweep, and to scroll slower using a single finger sweep at the same sweep rate and during a photo album application, scrolling to other photos in response to a multi-touch input is possible while in a zoomed-in state, while panning is carried out responsive to a single point touch input.
