Capacitive touch chips applied in the touch screens of all-in-one touch display terminals 1

Capacitive touch screens are a common touch screen technology widely used in various devices, including smartphones, tablets, laptops, and touch all-in-one computers. The core component of capacitive touch screens is the FDMS86101 capacitive touch chip, which is responsible for detecting and processing user touch signals. This article will provide a detailed introduction to the application of capacitive touch chips in touch all-in-one computer touch screens. diode

The working principle of capacitive touch chips is based on changes in capacitance. When a user touches the touchscreen surface with a finger or stylus, the current on the touchscreen changes. The capacitive touch chip detects this current variation and converts it into a touch signal. The touch chip then transforms these signals into digital signals and transmits them to the touchscreen controller. The controller determines the user's touch position and actions based on these signals.

On touch all-in-one machines, capacitive touch chips are primarily applied in the following aspects:

1. Multi-touch: The capacitive touch chip supports multi-touch functionality, enabling simultaneous detection and processing of multiple touch points. This allows users to operate the screen with multiple fingers or a stylus, such as zooming, scaling, and rotating, delivering a more natural and intuitive user experience.  diode
