Patent attributes
A system for inspecting a liquid crystal display (LCD) panel (10) includes a magnifier (11) for magnifying an image of the inspected LCD panel, a charge coupled device (CCD) camera (12) for capturing the magnified image of the inspected LCD panel, an image acquisition card (13) for converting analog signals of the magnified image into digital signals, and a computer (14). The computer is for obtaining color template intervals based on a statistical theory, rotating the magnified image when necessary, obtaining transverse mask codes and longitudinal mask codes of magnified image pixels, obtaining a color transverse mask code matrix of sub-pixels of the inspected LCD panel, and determining whether the sub-pixels of the inspected LCD panel are defective according to the color transverse mask matrix. A related method for inspecting an LCD is also provided.
