Its main features are as follows: When you touch the interface, your finger will draw some of its electricity, thereby lowering the electrostatic field. The upper glass layer has a clear/glossy surface. In this design, the voltage is applied to the corners of the screen. The transparent electrodes are normally made into diamond pattern with ito and with metal bridge.
