Abstract

See full text

A system is disclosed for repairing liquid crystal display panels that include a polarizing film. The system includes a laser repair optical system, a measurement optical system, and a processor. The laser repair optical system includes a polarization unit for modifying a polarization of a laser repair beam along a laser output path that is directed toward a workpiece. The measurement optical system includes an illumination source for providing measurement illumination along a measurement illumination path, and a detector for detecting reflected measurement illumination. The processor adjusts the polarization unit responsive to the reflected measurement illumination.
