Touch screen basic knowledge full analysis

- Aug 06, 2018-

There are several main types of touch screens: resistive (double layer), surface capacitance and inductive capacitance, surface acoustic, infrared, curved, active digital converter and optical imaging.They can also be divided into two categories, one requiring ITO, such as the first three touch screens, and the other requiring no ITO in the structure, such as the latter. 

Touch screens are already everywhere around us. In the field of personal portable devices such as PAD, touch screens save space for portable devices, and have better human-computer interaction.At present, the resistive touch screen and capacitive touch screen using ITO materials are most widely used in the market.
