Claim:
1. A multi-touch screen device comprising: x-axis transmitting modules including transmitting elements transmitting touch measurement signals radially to receiving elements being opposite to the transmitting elements; x-axis receiving modules including the receiving elements sequentially receiving the touch measurement signals transmitted by the transmitting elements at right and oblique angles; a controller calculating x and y coordinates of touch areas using only the touch measurement signals received by the x-axis receiving modules; and a touch panel receiving touch input from users, wherein the controller calculates the y coordinate of the touch area using Equation y(n)=f(x wherein y(n) represents virtual y-axis orthogonal coordinates calculated from the x-axis coordinates measured from right and oblique angle touch measurement signals, x wherein, if the kth receiving or transmitting element fails, the measurement value of the kth touch measurement signal is replaced with the measurement value of the k−1th touch measurement signal.
