<p><P>PROBLEM TO BE SOLVED: To provide a control circuit and a method for a capacitor type touch pad, and an application therefor. <P>SOLUTION: The control circuit and the method for the capacitor type touch pad and the application therefor reduce a basic capacitance of the capacitor type touch pad, enhance a sensor amount of the control circuit, provide a shielding effect, and reduce a noise to enhance an effect of the capacitor type touch pad, by charging and discharging each trace on the capacitor type touch pad, using a scan signal, and by reducing concurrently a parasitic capacitance between the trace adjacent to the trace or the trace scanned by supplying a signal of the phase same to the scan signal to an under-side earth layer, and the earth layer or the other trace. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
