绍了有源矩阵液晶显示器的主要缺陷形式。在采用冗余技术的基础上，研究了针对不同缺陷形式所应采取的不同的激光修补对策，由于加法激光修补仪价格昂贵，作者在美国Ｓｏｌａｒｅｘ公司工作期间开发出了利用减法激光修补仪进行加法修补的独特工艺 Introduced the main defects of the active matrix liquid crystal display form. Based on the redundancy technique, different laser repair strategies for different defect modes are studied. Since the additive laser repair device is expensive, the author developed the subtraction laser repair instrument during the work of Solarex Company in the United States Repair of the unique process
