Abstract
A method for detecting line broken faults of common electrode lines of liquid crystal display comprising: loading detection picture to the liquid crystal display, wherein said detection picture comprises at least one detection picture for line broken of common electrode lines, wherein, in the detection picture of same frame, the voltage difference of storage capacitor corresponding to pixel electrode with one polarity is larger than voltage difference of a storage capacitor corresponding to pixel electrode with another polarity; when the detection picture for line broken of common electrode line is displayed on the liquid crystal display, detecting whether there is black line or white line gradually changed in horizontal direction in said detection picture for line broken of common electrode line, and determining line broken fault of common electrode line exists in the liquid crystal display when there is a black line or white line gradually changed in horizontal direction.
