Foreign material method of detection and foreign material detection device of liquid crystal display panel

摘要

As for topic of this invention, when the short circuit by the foreign material of the conductivity which is mixed between the baseplate of the liquid crystal display panel is unstable, shorting this securely, it is to offer the foreign material method of detection of the liquid crystal display panel which can be actualized the indicatory defect by the conductive foreign material. As for the foreign material method of detection which relates to this invention, the baseplate of flexibiility of pair (21,26) the liquid crystal display panel where the liquid crystal lies between (20) being the foreign material method of detection which detects the presence of the foreign material of the conductivity which is mixed between the said baseplate, the support roller of the pair which supports the liquid crystal display panel which is provided on the aspect of one side of the liquid crystal display panel (3,3) with, being located between the support rollers which are provided on the other aspect the pushing pressure roller which the pushing it overpowers the liquid crystal display panel (4) making the liquid crystal display panel pass between, causing deflecting in the liquid crystal display panel, the baseplate in surface directionIt is something which is actualized the indicatory defect by the foreign material of the conductivity which is mixed between the baseplate by it tries to be shifted mutually.
