Abstract
A line detecting apparatus and a line detecting method for an array substrate relates to the field of line detecting technology. The detecting method comprises: arranging an input terminal sensor (30) at a signal input terminal of a wire to be detected, arranging one output terminal sensor (41, 42, 43) at a signal output terminal of the wire to be detected, and arranging other output terminal sensor (41, 42, 43) at a signal output terminal of another wire adjacent to the wire to be detected; measuring an output voltage of the wire to be detected by a voltage detector; and determining the line conduction condition of the wire to be detected according to the output voltage as measured. When the sensors perform line scan, the coordinate of the specific location where the short-circuit or open-circuit occurs can be found directly without performing scan by PDS or AOI, thus simplifying the technical processes, shortening the time for detecting, and saving the production cost.
