Capacitive touch screen classification
- Dec 11, 2018 -

Capacitive touch screens can be divided into several?

Surface capacitive: an ordinary ITO layer and a metal frame that discharge charge from the panel when a finger touches the screen.Sensing is done at the four corners of the touch screen, without the need for complex ITO patterns.

Projective capacitor type (inductive capacitor type)

One or more carefully designed etched ITO layers are used. These ITO layers are etched to form multiple horizontal and vertical electrodes.Projective capacitance type is divided into self - induction capacitance type and mutual inductance capacitance type.
