Blue phase liquid crystals (BPLCs) show fast response time and macroscopic optical isotropy due to their double twist cylinder structure. With polymer stabilization, the thermal stability of BPLCs can be improved dramatically. However, it induces some problems to the electro-optic properties of BPLCs material such as high driving voltage, hysteresis and so on. In this paper, different concentrations of chiral dopant, polymer network of the BPLC, and temperature effect are investigated to improve the electro-optic properties of BPLCs and analyze the mechanism that affect the electro-optic properties of the BPLCs device.
