<p>A touch screen reducing the computational burden of a control unit is provided to maximize the effective area and minimize the distortion of electric field by newly composing a pattern structure. A main pattern(51) exists on a single layer. The main pattern is the pattern which is formed according to four edges while being comprised of the electric resistance chain of the linear type. The wire is combined in the blind angle four edges in order to supply the power to the main pattern. X coordinate direction and Y coordinate directions are comprised on one single board. A sub pattern(52) minimizes the linear error by the voltage gradient of the touch screen.</p> |
