为降低TFT-LCD生产过程中切换残影不良的发生率,在考虑残影的主要影响因素基础上,采用实验设计(DOE)中的部分因子实验设计筛选该不良的显著因子,结合生产实际开展切换残影的改善研究工作。研究结果表明:DOE方法能有效辨别残影不良的显著因子有覆盖层(Over coater,OC)、重叠部分(ITO-Vcom Overlay,OL)和摩擦扭转力(Rubbing Torque),在实际生产的不良改善过程中,彩膜玻璃(Color Filter,CF)增加OC、加大OL和提高Rubbing Torque值均能有效降低残影不良发生率;研究结果为切换残影和改善TFT-LCD生产过程中其他不良提供了新思路。
To reduce the occurrence of TFT-LCD image-retention
several key factors were approved with fractional factorial design adopting the design of experiment (DOE). Through the practical production
we solved the problem about the image-retention. The results showed that the prominent factors of image-retention
including OC
OL and Rubbing Torque
can be effectively distinguished by DOE method. Moreover
by adding OC on CF
enlarging and ITO-Vcom Overlay
or increasing Rubbing Torque value
the incidence of image-retention during improvement can be effectively reduced. This study provided a new idea for other defect researches in image-retention and TFT-LCD production process.
