Claim One:
1. A method of processing data in a touch screen display device, the method comprising: generating a plurality of input coordinates in response to a touch operation on a touch panel; and generating a plurality of final coordinates by filtering the plurality of the input coordinates using a valid area that is flexibly set based on a direction and a speed of the touch operation, wherein generating the plurality of the input coordinates includes: generating a current detection coordinate by detecting a touch point on the touch panel; and generating a current input coordinate based on whether the current detection coordinate is included in a compensation area a center of which is located at a most recent final coordinate, the most recent final coordinate being a most recently generated final coordinate among the plurality of the final coordinates, and wherein generating the current input coordinate includes: determining the current input coordinate as a moved current detection coordinate when the current detection coordinate is included in the compensation area, the moved current detection coordinate being generated by moving the current detection coordinate such that a distance between the current detection coordinate and the most recent final coordinate is reduced; and determining the current input coordinate as the current detection coordinate when the current detection coordinate is excluded from the compensation area.
