Description

TECHNICAL FIELD

[0001] The application relates to the technical field of capacitive screen detection, in particular to an electric appliance capacitive screen conduction detection equipment. BACKGROUND

[0002] The capacitive touch screen technology works by using the current induction of a human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are coated with an ITO layer. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating layer serves as a working surface. Four electrodes are led out on the four corners. The inner layer ITO serves as a shielding layer to ensure a good working environment. When a finger touches the metal layer, a coupling capacitor is formed between the user and the touch screen surface due to the human body electric field. For high-frequency current, the capacitor is a direct conductor. Therefore, the finger absorbs a very small current from the contact point. The current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller calculates the position of the touch point by accurately calculating the proportion of the four currents.
