| 内容記述 | This paper describes some experiments for breaking a liquid crystal display panel using YAG laser. Popular mechanical cutting of the glass panel using small diamond wheel is not always high quality which brings lower productivity of the panel. Precise breaking of the panel with non-contact method using CO2 laser, is recently conducted enthusiastically. The excellent results, however, have not been obtained. Present experiments focus on high quality breaking of the display panel of STN liquid crystal in which some lenses of different focus are used. Breaking tests are performed in air under an ambient temperature using different size of specimens including the notchted ones. It is found that effective spot size of laser on the surface of specimen increases with the usage of longer focus lens which is related closely to the breaking quality of the glass. The lens with shorter focal length elevates the breaking rate of the glass plate and also improves the breaking quality of it. The experiments show that the rate of breaking is independent upon the size of the plate, but it is dependent on the shape of notch made at edge of the specimen. The choice of optimum condition for the breaking yields less meandering main crack and non-branching cracks which deteriorate the breaking quality of the glass plate. | |||||
