Problems solved by technology

[0004] However, this device has the following disadvantages: 1. The contact between the detection probe and the conductive layer depends entirely on the operator's visual observation and operating experience, and the operation difficulty is relatively high; 2. Since the tip diameter of the detection probe is 1um, the conductivity of the display panel The width of the layer is about 20um. In actual operation, it is necessary to repeatedly test the contact between the detection probe and the conductive layer under a microscope. The production efficiency is not high and time is wasted; 3. Repeated testing will cause serious wear of the conductive layer, resulting in inaccurate measurement data. 4. Continuous friction between the detection probe and the conductive layer will cause serious wear and tear of the detection probe, which needs to be replaced frequently, and the entire detection probe needs to be completely replaced, resulting in an increase in cost; 5. During the detection process, due to the increase in impedance or the accumulation of charges Injury to the panel after electrification
