fundamental structureThe basic structure of the capacitive touch screen is that the substrate is a single-layer plexiglass, a layer of transparent conductive film is evenly forged on the inner and outer surfaces of the plexiglass, and a narrow electrode is placed on the four corner cones of the tran

The types of capacitive touch screens are divided into surface capacitive touch screens and projection capacitive touch screens.Surface-type capacitive touch screenOften used is the surface capacitive touch screen, which is simple in working principle, cheap, simple to design the circuit, but diffic

Overview of principlesIn order to realize multi-touch control, the capacitor screen increases the electrodes' mutual capacitance. Simply put, the screen is divided into a group of mutual capacitor modules in each area to work independently. Therefore, the capacitive screen can independently detect t
