.Development of CRT’s corner cutting repair systems[J].Optoelectronics Letters,2005,1(3):182-184 Development of CRT’s corner cutting repair systems QU Hui-ming CHEN Qian School of Electronic Engineering and Optoelectronics Technology, Nanjing University of Science and Technology, Nanjing 210094, P. R. China Abstract:       CRT Corner cutting tube is considered as a definitive reject and will be sent to reclaim at all times. It caused lots of material loss. In this paper, a novel technology used to save CRTs corner cutting tube is presented firstly. A set of repair system has been successfully developed to repair CRTs corner cutting tube. Then, the process technology for corner cutting repair has been excogitated by empirical studies. Finally, the correlative performances of repaired tube are evaluated. The experimental results show that the quality of repaired tube has no difference with that of normal product. The repair yield has reached above 97 percent. This new technology has contributed to improving the production yield, reducing the material consumption and decreasing the cost of color CRT production.
