| The capacitive (SCAP) technology is applied on glass sensor that is added conductive coatings. The electrical charge is set at the four corners of the glass along an X-Y axis, and spreads the stable voltage on the glass as a uniform field. When a user touches the screen, some of the charge is transferred to the user, and makes the potential difference on the screen. After the panel controller recognizes that, the controller will send the X-Y axis information to the PC port. The advantage is that capacitive technology transmits almost 90% percent of the light from the screen. The superior efficiency gives capacitive better than resistive technology. |
