22.52 Inch Surface Capacitive Touch Screen
Operation Principle:
Capacitive touch panel works through body's current induction. When finger is on or close to touch panel surface, due to body electric field, the user and touch panel surface forms one coupling capacitance.
For high frequency current, capacitance is direct conductor, then fingers suck a small current from the contact point, through amplifying and accurately calculating this current signal,
Finally the controller works out the touch point position.
Surface Capacitive Touch Screen Technology:
| Comparison between Capacitive Touch Panel and Resistive Touch Panel | |
| Capacitive Touch Panel | Resistive Touch Panel |
| Touch (no pressure needed) | Press (pressure activated) |
| No calibration required | Calibration required (resistance drift on film) |
| Better Durability, No significant aging | Display turns white when aging |
| Handles high temperature | Film breaks down at high temperature |
| Better Transparency, less optical power needed | Low transmission |
| Can be vandal-proof (thick glass/plastic) | Easily damaged (thin top layer) |
| Scratch Resistant (with glass) | Prone to scratch |
| Stylus not a must | Need stylus, easy to lose |
