Abstract
Embodiments of the present invention disclose a method for detecting a bright spot of a liquid crystal display panel, which belongs to the field of display. 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. The method may be used for detecting liquid crystal display panels of ADS type.
