Claim Text:
1. A method for improving touch sensitivity in an electronic device having a capacitive type touch screen panel, the method comprising: sequentially driving a plurality of transmitting channels of the touch screen panel using a predetermined scan frequency; determining a number of adjacently touched receiving channels of a plurality of receiving channels by simultaneously scanning a plurality of receiving channels of the touch screen panel; specifying a scan unit to be used for dividing the plurality of receiving channels into groups on the basis of the number of adjacently touched receiving channels and for sequentially scanning the groups of the receiving channels; determining a touch coordinate by sequentially scanning the plurality of receiving channels using the specified scan unit; newly specifying the predetermined scan frequency based on the number of adjacently touched receiving channels; and sequentially driving the plurality of transmitting channels using the newly specified scan frequency, wherein the newly specifying of the scan frequency includes multiplying the predetermined scan frequency by the number of adjacently touched receiving channels.
