ADS TFT-LCD贴合产品按压漏光研究及改善
Improvement of press light-leakage in ADS TFT-LCD joint production
摘要
按压漏光是发生在ADS TFT-LCD贴合产品上的一种漏光不良, 本文对8.5G工厂1 225 mm (55 in)产品按压漏光的发生原因进行分析, 发现漏光为玻璃基板固定位置受外部应力作用形变导致。同时分析了辅助封框胶排布、封框胶固化前外部应力对基板的影响等。通过改变翻转台运动方式, 能有效改善按压漏光发生程度, 按压漏光发生等级由Level 2(L2, 客户不接受等级)下降至Level 1(L1, 客户接受等级)。该方法的首次导入, 为后续其他产品漏光的解决提供了思路。
Abstract
Press light-leakage was a defect in the joint production of ADS TFT-LCD. In this paper, the causes of press light-leakage in 1 225 mm(55 in) product based on 8.5G factory are analyzed. It is found that the light-leakage of fixed position is caused by external stress deformation. At the same time, the influence of the pattern of sealant on glass, and the stress of glass before sealant cured are studied. The defect is effectively improved by changing the motion mode of turn-over, the light-leakage level dropped from the second leve 2(L2,the phenomenon of customers don't accept) to the first level(L1,the phenomenon of customers accept). In addition, the method is implemented for the first time, and provides an idea for solving lisht-leakage for other products.
