摘要

本文对大尺寸产品中发生的高温运行液晶气泡不良进行了系统的分析与研究，从不良现象、机理假设出发，通过实验复现，总结出该不良的根因：封框胶在高温环境下，其接着力大幅下降，导致产生液晶气泡不良。论证了通过选用高

点封框胶材料和优化接着界面，提升其高温接着力，从而有效地解决此不良，确保产品品质，对提升液晶显示器生产良率和客户满意度具有重要意义。

Abstract

The liquid crystal bubble defect occurred in large-size products under high-temperature-operation-test are systematically analyzed and summarized from the occurrence of the defect

hypotheses on the mechanism

and through experimental tests to verify the hypothesis mechanism. It is concluded that the adhesive of the sealant is reduced greatly in the high temperature environment

resulting in the formation of liquid crystal bubble defect. At the same time

it is demonstrated that by selecting sealant materials with high

point and optimizing the bonding interface

the high-temperature adhesion is improved

thereby the problem is solved effectively

the product quality is ensured

and the production yield of LCD monitors and customer satisfaction are improved.
