Resistive and capacitive touch screens
Apr 28, 2018
Resistive touch screens have had their heyday in the past few years, and now the market uses resistive touch screens to drop significantly, and it is more suitable for low-cost designs. Users using these designs must wear gloves, for example: in medical, industrial and military environments. However, capacitive touch screens have gained widespread use. Capacitive touch screens are used in the mainstream smart phones and tablet computers currently on the market.
Resistive and capacitive touch screens
Both resistive and capacitive touch screens use indium tin oxide (ITO) sensors, but the use is quite different. Resistive touch screens use the mechanical force of a human touch to connect two flexible layers of ITO. The capacitive touch screen control uses: Basically, a person is a moving capacitor. Touching ITO changes the system's perceived capacitance level.
