Surface Capacitive
The capacitive sensor has a conductive coating on the front surface with wires connected to each corner. A small voltage is applied to each of these four corners. The operation relies on the capacitance of the human body. When a person touches the screen, a small current flows to the point of touch, causing a voltage drop which is sensed at the four corners.
| Advantages | Disadvantages |
| More durable than resistive (because the top layer is not plastic) |
Less durable as compared to other technologies |
| Higher transmittance than resistive (fewer layers) |
Less transmittance and overall optical quality |
| Requires periodic recalibration |
Surface capacitive technology is best for simple applications such as:
- Point-of-sale terminals
- Kiosks
- Gaming and amusement
