Improvement of electro‐optical properties of PSBP LCD using a double‐sided IPS electrode

— In this work, a low-hysteresis polymer-stabilized blue-phase LCD is developed by controlling the polymerization temperature and using a double-sided IPS (DS-IPS) electrode. Compared to a conventional IPS LCD, this DS-IPS LCD has a driving voltage of 45 V, which is lower than that, 62 V, of a conventional single-sided IPS LCD. The transmittance is increased approximately 23%. The hysteresis is reduced to 0.44% which decreases as a function of the operating voltage. Furthermore, simulations of the maximum transmittance and operation voltage associated with the offset between the electrodes in the top and bottom substrates were also evaluated.
