An image processing system has been designed, implemented and experimented for use in the Liquid Crystal Display fabrication. To improve the efficiency of throughput while LCDs conveyed in the fabrication process, an automatic system of the alignment and the dispensing detection are undertaken using image capture on an XY table. An explanation on the configuration of optics and the panel orientation correction are introduced. A cross marked key for alignment is captured by a CCD camera which provides us the coordinates and the orientation of the LCD. Implementations of the algorithm of the binarization, the edge detection and the thinning/skeletonization are executed in the Visual Basic language. The dispensing performance is investigated by calculation the dege width of the gluing material on the panels. The experimentation reveals us a satisfactory result and a user-friendly interface to personal computers.
