Why can only one finger be recognized when touching the phone screen with two fingers?
Due to the characteristics of capacitive touchscreens, if two fingers are too close together, the screen will interpret them as a single touch point due to interference.
For your reference, here are more details about the capacitive touchscreens:
1. Capacitive touchscreens use electrodes to create an electric field on the surface of the screen. A transparent conductive layer, such as indium tin oxide (ITO), covers the screen. When a finger touches the screen, it changes the capacitance of the electric field. The change in capacitance caused by the touch is detected by the screen's controller, which determines the location of the touch;
2. Capacitive touchscreens respond quickly to touch, providing a smooth and responsive user experience;
3. With no moving parts, capacitive touchscreens have fewer wear and tear issues, resulting in a longer lifespan;
4. The transparent conductive layer does not affect screen visibility, ensuring clear and sharp displays;
5. Capacitive touchscreens support multi-touch functionality, allowing complex gestures such as pinch-to-zoom.
