Front Screen Glass lens for iphone XR  

                                                                                    Capacitive touch screen structure      The structure of the capacitive touch screen is mainly to coat a transparent film body layer on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor.  The capacitive touch screen is coated with long and narrow electrodes on the four sides of the touch screen, forming a low-voltage AC electric field in the conductor. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides wil…
