A method and a device for detecting a touch position and a flat panel display using the method and the device are disclosed. The touch position detecting method includes generating touch data from a touch sensor array; computing the touch data input in each of adjacent frames to generate difference data and then performing at least one binary operation and a filtering operation on the difference data to correct the difference data; determining an effective area and then calculating a first central coordinate and a second central coordinate; computing a reference vector between the first central coordinate and the second central coordinate, a position vector between a position coordinate and the second central coordinate, and an angle between the reference vector and the position vector; and determining the position coordinate on the touch boundary portion at the angle having a minimum value as a touch coordinate.
