    • The circular polarizer comprises a liquid crystal cell, the liquid crystal layer (8) of which is present as a so-called "blue phase" and can be exposed to a variable electric field. The blue phase is an optically isotropic chiral phase which, like the cholesteric phase, reflects circularly polarized light within a narrow frequency band and accordingly, in this spectral region, transmits only light which is circularly polarized (in the opposite sense). Under the influence of the field, the reflection band changes its position and can be shifted almost continuously from blue to red by means of relatively small voltage changes.The circular polarizer can, by means of simple additional measures, for instance by including a color-neutral circular polarizer, be developed into a color modulator and, in particular, it also makes a multi-colored display of information possible.
    • 圆偏振器包括液晶单元,其液晶层(8)以所谓的“蓝相”存在并且可以暴露于可变电场。 蓝色相是光学各向同性手性相,其像胆甾醇相反射在窄频带内的圆偏振光,因此在该光谱区域中仅透射圆偏振(相反意义上的)的光。 在场的影响下,反射带改变其位置,并且可以通过相对较小的电压变化几乎连续地从蓝色变为红色。 圆偏振器可以通过简单的附加措施,例如通过包括彩色中性圆形偏振器,被开发成色调制器,并且特别地,它还使信息的多色显示成为可能。

    • An operable liquid crystal display device having threshold energy fields dependent on a finite temperature operating range is provided with a layer of a liquid crystal material positioned between the carrier plates of such device. The liquid crystal material includes a nematic carrier material and at least two doping chiral additives, one of which exhibits a clockwise twisting tendency and the other which exhibits a couter-clockwise twisting tendency. The twisting characteristic for the cholesteric phase has a temperature-dependent pitch and, under certain conditions, a temperature-dependent direction of rotation. With such a multiply-doped liquid crystal material and with the application of a controllable select energy field, such as electricity or magnetism to such material, selective display characteristic data can be generated by, for example, a temperature-independent pitch, a helix inversion, or a pitch which greatly increases or decreases with an increasing temperature within the finite temperature range. In such liquid crystal materials, the threshold field strengths are temperature-constant for different display effects or may be compensated to the temperature-dependency of other magnitudes, such as the temperature drift of a driving module designed as an integrated circuit.
    • 具有取决于有限温度操作范围的阈值能量场的可操作的液晶显示装置设置有位于这种装置的载体板之间的液晶材料层。 液晶材料包括向列型载体材料和至少两种掺杂手性添加剂,其中一种显示出顺时针扭转的趋势,另一种呈现出向下的扭转趋势。 胆甾醇相的扭转特性具有温度依赖性的间距,并且在某些条件下具有温度依赖的旋转方向。 利用这样的多重掺杂液晶材料,并且通过对这种材料施加诸如电或磁性的可控选择能量场,可以通过例如不依赖于温度的间距,螺旋反转来产生选择性显示特性数据 ,或在有限温度范围内随着温度升高而大大增加或减小的间距。 在这种液晶材料中,对于不同的显示效应,阈值场强是温度常数,或者可以补偿其他量级的温度依赖性,例如被设计为集成电路的驱动模块的温度漂移。
