报道了一种新型液晶显示屏间隙支撑隔垫物的关键技术,可以替换传统的半透/灰阶曝光工艺,仅使用一张普通的全透光罩即可实现不同的支撑高度需求,并且达到遮光的效果,大幅节约了制备成本,可用于曲面或柔性显示面板。其中,主要隔垫物由两层色阻材料堆叠衬垫并覆盖平坦化层及黑色的光阻材料形成高度,辅助隔垫物由一层色阻衬垫并覆盖平坦化层及黑色的光阻材料形成高度,主/辅隔垫物的各自高度及它们之间的段差可以通过改变衬垫色阻的尺寸及平坦化层厚度进行调节。这种调节方式可以使主隔垫物高度的调节范围达0.6

m之间调节,理想段差位于此区间内。基于上述技术制备的液晶显示屏具有良好的显示效果,可用于高世代大尺寸液晶显示面板的生产。
The key technology of a novel photo spacer (PS) for LCD was investigated in this paper. It could replace traditional half tone or gray tone process by normal full tone mask to obtian two more heights for supporting requirement. In addtion
light could be shaded at the same time
which saved the product cost. This technology could be used in curved or flexible LCD technology. In this technology
the main PS is formed by double color filter stacking
polymer film on array (PFA) and black photo spacer (BPS) layers
and the Sub PS is formed by color filter
PFA and BPS layers. The height difference of main-sub PS can be regulated by changing the size of color filter and the thickness of PFA. By using this method
the adjustment range of main PS height
sub PS height and their height difference can reach 0.6
0.5
and 0.2~1.3
μ
m
respectively. A LCD panel with above technology possesses good display performance.
