Abstract

The invention provides a blue-phase liquid crystal formula, which is characterized by comprising Component A and Component B, wherein the Component A simultaneously contains two chiral dopants, namely ZLI 4572 and ISO(60BA)2 with the mole concentration ratio of ZLI 4572 to ISO(60BA)2 being 5:95-95:5; and the Component B contains a main liquid crystal, two reactive monomers and a light starting agent. By the mixed chiral dopants of different rate, the blue-phase liquid crystal formula can be utilized to effectively reduce the saturation voltage of the blue-phase liquid crystal so as to minimize energy consumption.

Description

technical field

[0001] The invention relates to a blue-phase liquid crystal formula, in particular to a blue-phase liquid crystal formula that can reduce saturation voltage. Background technique

[0002] The blue phase (blue phase, BP) liquid crystal is a self-aggregated three-dimensional photonic crystal structure, and this liquid crystal phase usually occurs between the isotropic phase (Isotropic phase) and the cholesterol phase (Cholesteric phase). Generally, the blue phase liquid crystal exists in three stable thermodynamic phases blue I (BPI), blue II (BPII) and blue III (BPIII). BPI is body-centered cubic (body center cubic), BPII is simple cubic (simplecubic), and BPIII is approximately iso-like (iso-like), but no matter what kind of blue phase liquid crystal, because it is isotropic, so The lattice axiality in any direction is consistent, so it can also be regarded as a liquid crystal phase similar to isotropic.

[0003] The composition of the blue phase liquid cry...
