Touch screen capable of isolating noise signals

Image Number 9 for United States Patent #6661408.

A touch screen capable of isolating noise signals is mainly a touch screen installing at the front side of a liquid crystal display (LCD) screen or cathode ray tube (CRT) for eliminating electromagnetic and radio frequency interference received by the LCD and CRT. The touch screen includes an antenna like conductive wire which is able to receive same noise signals mixed in the touch control signals. The touch screen controller uses the noise signals received by the antenna wire to offset the noise signals in the controller for increasing accuracy of the touch screen.
