TFT-LCD（ThinFilmTransistor-LiquidCrystaldisplay）广泛用作智能手机、电视面板、电脑等便携电子终端的显示屏，并且市场需求逐年扩大。近年来大尺寸、高分辨、窄边框成为发展趋势，使得其工艺结构愈加复杂，线路尺寸已达到微米量级，传统的裸眼或者电气检测已经无法满足其缺陷检测的要求。自动光学检测凭借其非接触性、速度快、标准一致等优点大大提高检测效率、降低了成本，在液晶屏检测领域展现出很强的竞争优势。 自动光学检测最核心的部分是光学成像系统和图像处理算法，本论文针对TFT-LCD屏背板和面板线路的成像、背板组件缺陷检测和线路粒子压合检测三个问题进行研究，研究内容...TFT-LCD is widely used as smart phone, TV panels and other kinds of display screen, and the demand expand year by year. Along with the development, large size, high resolution, marrow border becomes a trend. The craft structure is complex, and the line size has reached the order of microns. The traditional naked eye or electrical detection has been unable to meet the requirements. Automatic optica...学位：工程硕士院系专业：物理科学与技术学院_工程硕士(电子与通信工程)学号：1982014115298
