[Prior Art] iw is the rapid development of the display panel industry. 'The control of production cost is becoming more and more important. Before assembling the panel module and other components, the panel module must be inspected to ensure the panel module. Production quality. The LCD panel module includes a scan driver, a data driver, and a flexible circuit board. In order to detect the quality of the panel, the traditional test machine provides an external signal source, and the external signal source transmits the detection signal to the input contact of the data driver of the panel module through the probe. The flexible circuit board is sent to the scan driver, and the data driver and the scan driver respectively provide the data signal and the scan signal, so that the panel displays the detection screen, and the tester performs the face inspection of the panel and removes the defective product. In order to avoid the assembly of unqualified panel modules and other components, the materials of other components are wasted, resulting in a high production cost. However, in the process of transmitting the detection signal to the f-driver and the scanning drive through the probe, it is often necessary to precisely align the probe with the scan driver or the f-drive drive input contact point, and (4) the probe is very capacitive (four) offset And with the incorrect == Ge Wei screen check, even burned due to improper short circuit (5) dragging the electronic components on the diligent or data drive.

In other words, the probe on the test machine must also be replaced periodically, which increases the production cost and the contact between the probe and the input contact. The oxidation of the surface causes the contact resistance between the input and the contacts of the probe disc to become large, which affects the bandwidth and quality of the signal transmission. During the detection process, it is difficult for the inspection personnel to distinguish the defective products and cause unnecessary, and the excessive screening fails. Products also increase production costs.

The detection signal has gradually disappeared for future detection. In addition, during the process of detecting the image, the electromagnetic radiation interference transmitted through the probe will also cause poor quality of the kneading surface, thereby affecting the written detection/supplied, so as to solve the shortcomings of the conventional probe contact transmission signal, and the health is good.
