新型TFT-LCD柱状隔垫物的形变研究

摘要

介绍了一种可应用于大尺寸TFT-LCD的新型柱状隔垫物(photo-spacer)材料.与已经量产的材料相比,该材料具有更高的弹性恢复率和外压形变承受能力.在相同生产条件下的对比实验显示,该材料经过230℃加热20 min柱高的缩小率为3.04％,具有较好的热稳定性.机械性能评价结果显示,摩擦压力对于Spacer柱高没有太大的影响.%A new photo-spacer applied in TFT-LCD production was introduced. This material not only could withstand greater deformation, but had a higher recovery rate than other material. Compared with the mass production material, it showed better heat tolerance at 230 ℃ for 20 min and its height reduction ratio was 3. 04%. It also showed little dependent on column Spacer height in rubbing processes under the same production condition.
