摘要

基于手性液晶的布拉格反射特性

设计了旋向相反的手性液晶所构成的红、绿、蓝三基色叠层级联结构

以达到增强单元反射率的目的。采用Berreman 44矩阵对其单元反射率进行了分析

比较了手性液晶的单旋向三基色叠层(三叠层结构)与双旋向三基色叠层(六叠层结构)单元的反射谱

给出了改变液晶材料参数和级联顺序进一步提高单元反射率的计算结果。在最佳参数与级联顺序下

六叠层单元的最大反射率达到98.91%

三叠层单元的最大反射率为64.95%。叠层结构单元的色度分析结果表明

三层单元的色温依级联液晶旋向而改变

范围为5 240.9~7 029.8 K

在反射率最优的条件下

六叠层单元的色温为6 285.7 K。

Abstract

Based on the Bragg reflection of cholesteric liquid crystal

a structure is designed

which is formed by opposite charities of cholesteric liquid crystal of red

green and blue to enhance the reflectivity. This thesis reports the reflective spectra of LCD cells by the 44 matrix method. With the comparison of reflective spectra between solo RBG three-element-colors stack (three-layers) and the opposite RBG three-element-colors stack (six-layers)

the calculated reflectivity is given by changing the parameters of liquid crystal. In the best condition

the reflectivity of a six-layers LCD stack reach the maximum of 98.91% while the reflectivity of a three-layers LCD stack reach the maximum of 64.95%. This thesis also reports the result of chromaticity analogy of the LCD stack

which ranging from 5 240.9 K to 7 029.8 K. Overall

in the best condition

the chromaticity of a six-layers LCD stack is 6 285.7 K.
