Description

Technical Field

[0001] The present invention relates to the technical field of capacitive touch screens, and particularly to a combined anti-interference capacitive touch screen. Background Art

[0002] Capacitive touch screen technology works by utilizing the current induction of the human body. A capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating serves as the working surface, and four electrodes are led out from the four corners. The inner layer ITO is a shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the human body electric field, a coupling capacitor is formed between the user and the touch screen surface. For high-frequency current, the capacitor is a direct conductor, so the finger absorbs a very small current from the contact point.

[0003] Most of the existing capacitive touch screens are applied in the mechanical field. In some large CNC machine tools, capacitive touch screens are required for control. However, most touch screens are directly placed on the machine for use. When the machine is operating, it may cause the capacitive touch screen to fall off, resulting in damage to the capacitive touch screen. Summary of the Invention
