Abstract
The present invention provides a liquid crystal display panel repairing method and repairing system. The method includes: (1) providing a liquid crystal display panel, in which the liquid crystal display panel has a circuit that has a breaking site; and (2) applying laser chemical vapor deposition to form graphene on the liquid crystal display panel in such a way as to joint the breaking site. The liquid crystal display panel repairing method and repairing system of the present invention use laser chemical vapor deposition to form graphene on a breaking site to repair the breaking site. The process is simple and the result of repairing is good. Further, a common gas, such as methane, is used as a carbon source gas, making it favorable for environmental protection. Further, the number of layers of graphene so formed can be controlled by controlling whether to apply irradiation of the laser so as to achieve control of electrical conductivity of the graphene so formed and enhance the result of repairing. Further, the light spot of laser can be adjusted in regard to the radius thereof in order to control the resolution of graphene grown line and the optic path of the laser can be adjus…
