4.2: Polymer‐Stabilized Blue‐Phase Material Driven at Low Voltage

Abstract: We achieved low-voltage driving of a blue-phase liquid crystal display by employing liquid crystal with high dielectric anisotropy and a chiral material with high helical twisting power. A prototype of a 3.4-inch polymer-stabilized blue-phase display was made, which includes a highly reliable crystalline oxide semiconductor and operates favorably.

“…It is known that the V req of CLC is also proportional to ( k 22 /Δε) 1/2 , where k 22 is the twist elastic constant and Δε is the dielectric anisotropy . Therefore, a more effective approach is to employ a chiral additive with high twisting power (such as R5011) , and a nematic host with large Δε and small k 22 , , so that the optical performance can be well maintained. The use of high-twisting-power chiral additive reduces the concentration required to produce the same Bragg reflection color in the P state.…”
