OLIGOSILOXANMODIFIZIERTE FLÜSSIGKRISTALLFORMULIERUNGEN UND DAVON GEBRAUCH MACHENDE VORRICHTUNGEN |
摘要 |
<p>A liquid crystal formulation is described. The liquid crystal formulation comprises a first oligosiloxane-modified nano-phase segregating liquid crystalline material; and at least one additional material selected from a second oligosiloxane-modified nano-phase segregating liquid crystalline material, non-liquid crystalline oligosiloxane-modified materials, organic liquid crystalline materials, or organic non-liquid crystalline materials, wherein the liquid crystal formulation is nano-phase segregated in the SmC* phase, has an I→SmC* phase transition, with a SmC* temperature range from about 15° C. to about 35° C., has a tilt angle of about 22.5°±6° or about 45°±6°, and has a spontaneous polarization of less than about 50 nC/cm2, and a rotational viscosity of less than about 600 cP. Devices containing liquid crystal formulations are also described. The device has a stable bookshelf geometry, bistable switching, and isothermal electric field alignment, a response time of less than 500μs when switched between two stable states, and an electric drive field of less than about 30 V/μm.</p> |
