Abstract
Disclosed is a visual inspection apparatus for a glass substrate of a liquid crystal display, comprising an inspection platform and at least two slide rails. The glass substrate for inspection is fixedly located on an inspection platform main body. The slide rails are installed at two adjacent sides of the main body leastwise. Length directions of the slide rails are parallel with a level of the main body. The lengths of the two adjacent slide rails are mutually perpendicular; the visual inspection apparatus further comprises a coordinate reader. The coordinate reader is slidably jointed to the slide rails and employed to cross above the level of the main body to form a locating point. An inspector reads a coordinate of the locating point to acquire a corresponding coordinate of the glass substrate. The present invention also provides an inspection method for a glass substrate of a liquid crystal display.
