The method can solve a technical problem of miss detecting by the bright spot detection method in the prior art which o can not detect a bright spot caused by the short circuit between a data line and a pixel electrode. The method for detecting a bright spot of a liquid crystal display panel comprises: scanning gate lines of the liquid crystal display panel, and simultaneously outputting low level signals by data lines of the liquid crystal display panel; and, stopping the scanning of the gate lines of the liquid crystal display panel, and simultaneously outputting high level signals by the data lines.
