Description
| There are two major types of touchpads | |
| Resistive: | |
| The resistive touchpad consists of two membranes. When a finger or other object depresses the top membrane with a certain pressure, the membrane touches the underlying one. The connected controller recognises where the two foils are touching each other and sends the information to the PC. | |
| This is the older version and is rarely used. We carry only capacitive touchpads. | |
| Capacitive: | |
| The capacitive touchpad consists of a PCB covered with a foil for design and protection. An electrical feild is generated above the front of the PCB. When a finger touches any place on the touchpad area, the electrical feild is changed. The controller on the back of the PCB converts this change to the position on the pad and into a musesignal that is transferred to the PC. | |
| The advantages of a capacitive touchpad are: | |
| |
| The surface design can be changed to suit the customers needs and preferences. | |
