    • A touch panel according to the disclosure includes 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 connected between first and second Y electrode lines adjacent to each other, wherein the touch position on the touch screen is detected based on output codes prepared by using output values of the comparators. A method for detecting a position of a touch panel according to the disclosure includes the steps of generating a position signal that varies according to a touch position between a plurality of X electrode lines and first and second Y electrode lines, which are adjacent to each other and alternately disposed with X electrode lines; detecting adjacent signals from a Y electrode line adjacent to a left of the first Y electrode and a Y electrode line adjacent to a right of the second Y electrode line; inputting the adjacent signal as an input signal of the comparator; overlapping the position signal on one of the detected adjacent signals; and comparing the input signal using the comparator. An integrated circuit according to the disclosure includes a plurality of comparators including a positive input terminal receiving a first input signal that varies depending on a touch position, a negative input terminal receiving a second input signal, and an output terminal outputting a comparison signal of the first and second input signals; and an operation unit generating a position signal by reading out the comparison signal of the comparators.
