Device and method for repairing disconnection of liquid crystal panel

Abstract

The invention discloses a liquid crystal panel broken wire repairing device. The device comprises a broken wire detecting module, a control module, a printing box and a printing box moving module, wherein the broken wire detecting module is used for detecting the broken wire position and the broken wire length of a liquid crystal panel broken wire; the control module is connected with the broken wire detecting module, and is used for generating moving control signals and printing box control signals according to the broken wire position and the broken wire length respectively; the printing box is arranged on the printing box moving module; the printing box moving module moves the printing box to the position of the liquid crystal panel broken wire according to the moving control signals; the printing box forms a connecting part coordinated with the liquid crystal panel broken wire according to the printing box control signals, and coats the connecting part to the position of the liquid crystal panel broken wire; so that the repairing of the liquid crystal panel broken wire is realized. Duration consumed by broken wire repairing is shorter, the repairing efficiency of the liquid crystal panel broken wire is effectively improved, and output of liquid crystal panel desktops and the productivity of liquid crystal panels are ensured.

Description

Technical field [0001] The invention relates to the technical field of liquid crystal display, and in particular to a device and method for repairing a broken line of a liquid crystal panel. Background technique [0002] In the process of making Thin Film Transistor-Liquid Crystal Display (TFT-LCD) panels, due to factors such as film quality, environmental cleanliness, scratches, and production equipment, it will inevitably cause The TFT-LCD panel produced has a circuit break. However, the circuit break of the TFT-LCD panel will cause the TFT-LCD panel to have the defect of poor line after lighting, which will reduce the display quality of the TFT-LCD panel, and even cause the panel to be scrapped. [0003] In order to repair the circuit break in the TFT-LCD panel, gold glue coating equipment is usually used to repair the circuit break. figure 1 Shows the physical picture of the partial structure of the existing gold glue coating equipment. When using this device to repair the cir...

Problems solved by technology

However, because the needles used in the existing TFT-LCD panel disconnection repairing devices are very small (usually about 5 μm), this causes the repair speed of the existing disconnection repairing devices to be relatively slow.

The larger the disconnected area that needs to be fixed, the longer it will take

For example, using the existing TFT-LCD panel disconnection repair device to repair a disconnection with a length of 50 μm and a width of 10 μm, the coating time is about 65 seconds, which greatly limits the output of TFT-LCD machines and TFT -Capacity of LCD panels
