Abstract: A method and an apparatus for improving touch sensitivity of a capacitive type touch screen panel are provided. In the method, the apparatus sequentially drives a plurality of transmitting channels of the touch screen panel using a predetermined scan frequency. The apparatus determines a sequential touch count by simultaneously scanning a plurality of receiving channels of the touch screen panel wherein the sequential touch count is the number of sequentially touched receiving channels. Also, the apparatus specifies a scan unit to be used for dividing the plurality of receiving channels into groups on the basis of the sequential touch count and for sequentially scanning the groups of the receiving channels. The apparatus determines a touch coordinate by sequentially scanning the plurality of receiving channels using the specified scan unit.
