how does touchscreen work？
With the popularity of smart devices, touch screens have become a key interface for human-computer interaction. Divided into resistive and capacitive types. Resistive type relies on pressure to make the two conductive layers in contact, with accurate positioning but only supporting single touch; Capacitive touch utilizes human static electricity to alter the surface electric field distribution of the screen, achieving multi touch control.
As a professional manufacturer of TFT LCD display screens, our capacitive touch screens are usually combined with TFT panels through full lamination or frame lamination processes to form an integrated module of "touch+display". Its core structure consists of an upper cover plate (protection), a touch sensing layer (ITO glass or thin film), and a TFT display layer. During operation, the touch chip scans the capacitance changes of the sensing layer in real-time, accurately calculates the touch position, and transmits the signal to the motherboard through FPC cable, ultimately
