8. A touch screen display comprising:
-
a touch screen panel having a plurality of touch sensors; a display driver circuit configured to convert sensor signals generated according to positions sensed by the touch sensors into digital data associated with touch screen positions; an application processor configured to generate touch sensitivity control information of the touch screen panel in response to control inputs from a user; and a controller configured to; change the threshold value on the basis of the touch sensitivity control information transmitted from the application processor, determine sensor data values from the digital data for each of a plurality of sets of frames corresponding to the touch screen positions, and determine differences between the digital data values corresponding to neighboring frames of the touch screen and compare the differences to the threshold value to determine the existence of a touch event and a touch position in the touch screen panel. - View Dependent Claims (9, 10, 11, 12, 13, 14)
