Embodiment Construction
[0045] In order to have a better understanding of the above-mentioned and other aspects of the present invention, the preferred embodiments are specifically cited below, together with the accompanying drawings, and described in detail as follows:
[0046] The following describes the problems and solutions of the high operating bias of the blue-phase liquid crystals known to the inventors, and the display device developed by applying the solutions.
[0047] When the blue-phase liquid crystal display uses a bias voltage to generate an electric field, the equivalent refractive index ellipsoid of the blue-phase liquid crystal becomes anisotropic, resulting in a birefringence (birefringence) effect. The formula for the birefringence is Δn=λKE 2 , where λ is the wavelength of light, K is the Kerr coefficient, and E is the electric field generated by applying a bias voltage. Therefore, if you want to reduce the applied bias voltage, you can start by increasing the Kerr coefficient K....
