Detailed explanation-1: -A surface capacitive touchscreen uses a transparent layer of conductive film overlaid onto a glass sublayer. A protective layer is then applied to the conductive film. Voltage is applied to the electrodes on the four corners of the glass sublayer to generate a uniform electric field.
Detailed explanation-2: -The five most common types of touch screen are: 5-Wire Resistive, Surface Capacitive touch, Projected Capacitive (P-Cap), SAW (Surface Acoustic Wave), and IR (Infrared).
Detailed explanation-3: -As such, there are 4 touch panel types in regular use – Resistive, Optical Imaging, Projected Capacitive, and Infrared.
Detailed explanation-4: -Capacitive touchscreens are found on smartphones, tablets and other mobile devices. These include Android devices and Apple devices like an iPhone and iPad. Mobile devices like an iPhone, iPad and Android devices use capacitive touchscreens.
