Abstract: Disclosed are polarization-independent electro-optical compositions using dichroic-dye-doped polymer stabilized optically isotropic chiral liquid crystals. The isotropic phase of such compositions can be well maintained even if the temperature is below 0 °C. The electro-optical performances of such compositions demonstrate large Kerr constants, fast response times, and large contrast ratios of the compositions. The power consumption and the cost of devices based on the compositions can be decreased substantially due to alignment-free and polarizer-free characteristics. The compositions can be used to generate low power consumption displays and other photonic devices.
