7 inch capacitive touch screen module


7 inch capacitive touch screen module stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

Components of a Touch Screen



  • Touch sensor – A touch-responsive surface, usually a glass panel placed over a visual display monitor. The technologies vary slightly but, typically, the sensor registers change in electrical signal distortion to sense a touch event and location.

  • Controller – An electronic device (PCB) is the interface between the sensor and the display. The controller takes information from the touch screen and translates it into information a computer can understand.

  • Software driver – A computer program enables the computer operating system and the controller to communicate.
