<p>PURPOSE: A rechargeable touch screen panel is provided to arrange switching element about each touch cell in non visual area, thereby recognizing a multi touch irrelevant to a point number. CONSTITUTION: A touch cell(60) includes a transparent conductive pad(50). The transparent conductive pad forms a capacitance. A switching device IC(Integrated Circuit) unit is connected with a transparent signal line in a non-visible area. The switching device IC unit includes a switching device for a signal detection(44). A switching device for a signal detection detects a signal in a transparent pad. A driver IC(70) recognizes a touch input coordinate from the detected signal.</p> |
