彩色液晶显示器件（CLCD），在相同电压驱动条件下各波长透射率有很大的差别，从而引起图像显示的色彩饱和度或还原性不够。用UV-Vis8500型双光束紫外/可见分光光度计测量在不同电压驱动下负性VA-LCD的电光特性，对三基色的阈值特性和阈值特性随波长变化关系进行分析。结果表明，阈值电压Vth，饱和电压Vsat和中值电压V50都是随着波长的增加而逐渐增大，并且饱和电压与阈值电压之差随着波长的增加而变大。对常用三种中心波长500.0 nm、550.0 nm和600.0 nm的中值电压V50作为驱动电压进行分析，其结果为CLCD选取驱动电压提供一定的指导作用。

The electro-optical characteristics of negative VA-LCD driven by different voltage are measured by UV-Vis8500 double beam ultraviolet (UV)/visible spectrophotometer. The threshold characteristics of three prima-ry colors and the characteristics variation with wavelength are analyzed. The results show that threshold voltage (Vth), saturation voltage (Vsat) and mid-value voltage (V50) all increase gradually with the increasing of wavelength. And the difference between Vsat and Vth becomes larger gradually with the increasing of wavelength. Common used mean voltage V50 of three kinds of central wavelength such as 500.0 nm, 550.0 nm and 600.0 nm is taken as driving voltage to analyze. The results can provide certain guidance for choosing the driving voltage of colorful liquid crys-tal display (CLCD).
