摘要
用MLC-7700-100向列相液晶制备光栅常量为100μm、占空比为0.5的液晶光栅。并且温度为25℃时,在频率为100 Hz的交流电压驱动下,用UV-Vis 8500型双光束紫外/可见分光光度计测试液晶光栅三基色R(700.0 nm)、G(546.1 nm)、B(435.8 nm)的电光特性,得到三基色的T-V电光特性曲线,分析液晶光栅在对三基色的光谱特性变化。结果表明,液晶光栅在电压驱动下三基色的电光特性变化比较大,透射率差值最大为6.11%,最小为1.13%,以此作为基础,可对颜色进行一定的校正和补偿,以获得精确的色调和色饱和,便于进一步研究液晶光栅作为光学器件的显示性能。
Liquid crystal gratings with grating constant of 100 μm,and duty cycle of 0.5,were prepared using MLC-7700-100.By using UV-Vis 8500 double-beam UV/Vis spectrometer,the electro-optical properties of tricolor R（700.0 nm）,G（546.1 nm）,B（435.8 nm） of the liquid crystal grating driven by the AC voltage with frequency of 100 Hz were measured at a temperature of 25 ℃. The tricolor′s T-V electro-optical characteristics were obtained,and the spectral changes of tricolor in the liquid crystal grating were analyzed.The results show that the tricolor＇s electro-optical changes are relatively obvious.Maximum and minimum differences of transmittances are found to be 6.11% and 1.13%, respectively.Base on these results,it could be carried out color correction and compensation to obtain precise hue and color saturation,furthermore,to facilitate the further study on the display performance of the liquid crystal grating as an optical display device′s.
