VA型液晶屏在高温应用环境下经常会出现周边Mura。对于传统的成盒设计和工艺条件
框胶内的spacer粒径和灌晶后的封口压力的调整和优化是改善周边Mura的常用的、比较便捷的方法之一。通过对框胶spacer粒径、液晶盒封口压力和玻璃基板的比较实验
提出了改善周边Mura的措施
并验证了其有效性。
Edge Mura is always appeared in the vertical alignment LCD at high temperature condition. Adjustment and optimization of the seal spacer size and closing force are the common and feasible ways to improve the edge Mura. The experiments with different seal spacer size
closing force and glass type are done to improve the edge Mura. The improved perfor-mance of the edge Mura is verified by the visual check. And it shows the solution is effective.
