A composition for use with liquid crystal compositions in liquid crystal display devices, which possesses both a chromophoric moiety and a helical ordering moiety. The helical ordering moiety is capable of helically ordering a mixture of liquid crystal material and helichromic compound. The helichromic compound can be utilized in conventional "guest-host" and "twist nematic" displays as well as in unique helichromic displays. When used in helichromic displays, the helichromic compounds eliminate after-image scattering and enable the display to be operated at reduced voltages.
一种用于液晶显示设备中液晶成分的组合物,它同时具有发色团分子和螺旋排序分子。螺旋有序分子能够使液晶材料和螺旋铬化合物的混合物螺旋有序。该斜向铬化合物可用于传统的 "客主 "和 "扭曲向列 "显示屏,也可用于独特的斜向铬显示屏。当螺旋基质化合物用于螺旋基质显示屏时,可消除残像散射,并使显示屏在较低的电压下工作。
