Capacitive touch chips used in touch panels 2

3. Control circuit: used to control the operation of touch chips. The control circuit typically includes a microprocessor and related circuit components for processing and interpreting signals received from the sensing electrode array.

4. Digital interface: used for communication with external devices. Digital interfaces typically include serial interfaces, parallel interfaces, etc., used to connect touch chips with main control chips or other devices.

In terms of application, capacitive touch chips can achieve functions such as multi touch and gesture recognition. By sampling and analyzing multiple sensing electrodes on the touch panel, the positions and actions of multiple touch points can be detected simultaneously. This allows users to use multi finger gestures for operations such as zooming in and out, rotating, sliding, etc. Meanwhile, capacitive touch chips can also achieve more functions by recognizing touch actions, such as double clicking, long pressing, dragging, etc.  diode
