<p><P>PROBLEM TO BE SOLVED: To provide a touch screen system using frequency sensing method, and a flat display screen provided therewith. <P>SOLUTION: The touch screen system comprises a translucent insulating substrate 100, a signal generation part 200 for generating a first signal having a predetermined frequency, disposed on the substrate, and a wireless touch part 400 for generating and emitting a second signal having a frequency different from that of the first signal onto the substrate for touching an optional point on the substrate; a signal receiving part 300 for receiving signals propagated through the substrate, disposed on the substrate so as to face the signal generation part, and a control part 500 for sensing a touch point on the substrate by measuring frequency change in the signals received in the signal receiving part. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
