<p>PURPOSE: An analog digital hybrid type resistive touch screen is provided to remarkably reduce the number of bias electrodes and conductive films by detecting a touch point through a hybrid method which adopts an analog method and a digital method together. CONSTITUTION: A first conductive film includes stripe-shaped first conductive films(112a-112i) on which a first electrode is formed. A second conductive film includes stripe-shaped second conductive films(122a-122i) comprising a second electrode and intersects the first conductive film. An intersection electrode(125) connects both ends of the second conductive films to connect the second conductive films serially. From the voltage value detected through the first and second conductive films, a control unit generates plural planar position coordinates which have first and second coordinates constituting one position coordinate.</p> |
