S-Cap

Similar Terms: Surface Capacitive,SCAP,Touch Screen,touchscreen

There are two major categories of touchscreen displays: surface capacitive touchscreens and resistive touchscreens. Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

 

S-Cap technology is applied on a glass sensor that hass 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.
