Embodiment Construction
[0021] First of all, the original design intention of the present invention is explained. The capacitive touch screen technology uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and 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 is used as the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the shielding layer to ensure a good working environment. During the production process of the electrical capacitance screen, it is necessary to Carry out conduction detection to ensure the service life of the capacitive screen. Most of the existing detection process is through manual detection. This method is low in efficiency and labor-intensive for workers. The detection device has a complex structure, high cost, low detection efficienc...
