Claim:
1. A touch panel comprising: a touch screen including a plurality of X electrode lines and Y electrode lines, which are alternately disposed with each other, and generating signals that vary depending on a touch position; and a plurality of comparators, the plurality of first comparators including: wherein the first comparators are connected in parallel to each other, and the second comparators are connected in parallel to each other, wherein the first input signal of the second comparators is provided from a first Y electrode line of the touch screen and the second input signal of the second comparators is provided from a second Y electrode line of the touch screen, wherein the touch position on the touch screen is detected based on output codes prepared by using output values of the second comparators, and wherein, when a pitch between the first and second Y electrode lines adjacent to each other is set to 1/n(n>2) touch resolution, (n−1) comparators are disposed in parallel between the first and second Y electrode lines adjacent to each other, wherein n is an integer greater than one.
