  • Publication number: 20120050184
    Abstract: Disclosed herein is a method of controlling driving of a touch panel. Input means inputs a first touch to a touch surface, and whether the first touch is a line touch is determined. If the first touch is a line touch, the touch surface is divided into first and second selection regions, based on the line touch. The input means inputs a second touch to the touch surface, and one of the first and second selection regions is selected. When the first selection region is selected by the second touch, if the input means inputs a third touch to the second selection region, a specific algorithm is executed in the second selection region, whereas when the second selection region is selected by the second touch, if the input means inputs the third touch to the first selection region, the specific algorithm is executed in the first selection region.
