Capacitive touch circuit: This product adopts PEDOT or ITO transparent capacitive buttons, and is laminated with high transparent adhesive materials such as OCA, developed and produced according to the different needs of customers. The product control interface is designed as a touch capacitor circuit. When the button is touched by hand, the capacitance value will be enlarged and this signal will be provided to the IC chip. The chip will issue different instructions to the device according to the signal amplified by the capacitance value of the corresponding point. On this basis, it provides users with a human-computer interaction experience different from traditional switches.
