  • Patent number: 11561252
    Abstract: The present disclosure relates to a coaxial lead structure and method for radiating a GIS partial discharge UHF signal outward. The structure includes a GIS cavity, a circular hole provided on the GIS cavity, a medium cylinder provided at the circular hole and sealing the circular hole, a thin cylindrical metal lead that extends into and is fixed to the medium cylinder, and a ground lead connected to the thin cylindrical metal lead. According to the present disclosure, a relatively strong signal may be obtained outside a coaxial lead structure, and detection of a partial discharge UHF signal at this position may increase the detection sensitivity by one time compared with the detection methods of built-in and external disc insulators.

  • Patent number: 9759970
    Abstract: A liquid crystal display (LCD), an array substrate of the LCD and a method for repairing a broken line are disclosed. According to the present invention, a detection line and a repairing line are disposed on an array substrate of the LCD, the detection line is connected to a non-defective scan line and the repairing line is connected to a broken line; and when a scan signal is detected by the repairing IC via the detection line, a repairing signal is outputted at an appropriate time to repair the broken line via the repairing line. With this arrangement of the LCD and the method for repairing a broken line of the present invention, broken scan lines that are detected in the LCD after the cell process can still be repaired. This reduces the reject ratio, avoids unnecessary waste and lowers the manufacturing cost.

  • Patent number: 9312281
    Abstract: A TFT array substrate includes a pixel region and a wiring region disposed outside the pixel region. The wiring region has a wiring layer including scan or data wirings. A repair wiring layer including repair wiring is disposed insulatedly below or above the wiring layer. A scan or data wiring has a first intersection and a second intersection with a repair wiring section of the repair wiring. When the scan or data wiring is broken, a repair wiring section is cut off the repair wiring by a first cut-off point and a second cut-off point, and the broken scan or data wiring is electrically connected to the repair wiring section through soldering the first intersection and the second intersection. Thus, products that would otherwise be rejected in the manufacturing process of LCD panels can be repaired, which decreases the reject ratio, increases the yield and saves the production cost.
