Alignment film repairing method capable of saving repairing cost

Abstract

An alignment film repairing method capable of saving the repairing cost includes: establishing a visual image of an object to be tested, defining a defect frame option area after it is determined thatan alignment film has defects, and defining a plurality of removing designated areas according to the defect frame option area; generating an binaryzation image of the visual image so as to find a block corresponding to the defects; comparing if each removing designated area is overlapped with the block or not so as to retain the removing designated areas overlapped with the block, and then performing laser removing and repairing solution filling on the removing designated areas overlapped with the block, wherein removing designated areas separating from the block are corresponding to normalparts of the alignment film and can be excluded, and later laser removing and repairing solution filling of the removing designated areas separating from the block can be avoided. The alignment film repairing method can effectively reduce and shorten the area and the time of laser removing and repairing solution filling, and can save the repairing cost.

Description

technical field [0001] The invention relates to the technical field of alignment film repair, in particular to an alignment film repair method that can save repair costs. Background technique [0002] The liquid crystal molecules in the liquid crystal display are arranged randomly in the natural state, and the alignment direction and angle of the liquid crystal molecules need to be controlled by the alignment film. In order to ensure the coating quality of the alignment film, the alignment film needs to be checked and repaired by an alignment film repair machine. repair. [0003] The known alignment film repairing machine mainly includes a control host, a stage, and an image capture device, a laser generating device, and a repair liquid filling device arranged above the stage. The image capture device, the laser generating device The repair fluid filling device can be arranged on a transmission device. The control host is electrically connected to the transmission device, ...
