Description

technical field [0001] The invention relates to the technical field of capacitive screen detection, in particular to a conduction detection device for electric capacitive screens. Background technique [0002] 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, and the outermost layer is a thin layer of silica glass protective layer. , the interlayer ITO coating is used as the working surface, and four electrodes are drawn from the four corners. The inner layer of ITO is the shielding layer to ensure a good working environment. When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a A coupling capacitor, for high-frequency current, the capacitor is a direct conductor, so the finger draws a small current...

Problems solved by technology

[0003] In the production process of electrical capacitive screens, conduction testing needs to be carried out to ensure the service life of the capacitive screens. Most of the existing testing processes are manually tested. This method of testing has low efficiency and high labor intensity for workers. Through the detection of the existing detection device, the existing detection device has a complex structure, high cost, low detection efficiency, low detection accuracy, and inaccurate detection results, resulting in a low service life of the capacitive screen. Therefore, it is necessary to design A conduction detection device for an electric capacitive screen, which improves detection efficiency and detection accuracy
