A guest-host smectic cell incorporates an alkyl 1,4-diaminoanthraquinone-2-carboxylate blue dye which is relatively highly resistant to degradation when exposed to the fields and current densities typically employed for switching by means of electrohydrodynamic induced instability effects. Such dyes may be employed admixed with other stable dyes to provide a black dye.
这种染料在电场和电流密度下具有较强的抗降解能力,通常通过电流体动力诱导的不稳定效应进行切换。 这种染料可与其他稳定染料混合使用,以提供一种黑色染料。
