TOUCH SCREEN DISPLAY DEVICE AND DRIVING METHOD OF THE SAME
First Claim
1. A touch screen display device, comprising:
- a touch screen display panel comprising a plurality of first sensing lines that extend in a first direction, a plurality of second sensing lines that extend in a second direction that crosses the first direction, and a plurality of touch sensing elements respectively arranged at areas where the first sensing lines and the second sensing lines cross each other; and
a read-out unit that receives output signals of the first sensing line and the second sensing line, that reads at least one sensing position, and that outputs at least one of the read sensing position as a touch position,wherein if the number of the sensing position of the current frame is equal to or greater than two, the read-out unit compares the at least two sensing positions of the current frame with a touch position of the previous frame, and outputs the sensing position that is closest to the touch position of the previous frame as the touch position of the current frame.
