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.

Description

Background technique [0002] In recent years, the use of mobile terminals has grown rapidly to become an everyday item in today's society. The functions of general-purpose mobile terminals have been enhanced from processing voice calls to data transmission, digital photographing and storage, multimedia communication functions, and the like. The recently developed touch screen technology has been applied to mobile terminals, so that the preference for touch screen based mobile terminals has greatly increased. [0003] During various operations, the mobile terminal displays a scrollable information screen, such as a phonebook contact list screen, a browser screen (ie, a web page), or a digital photo album. More specifically, a mobile terminal typically disp...
