Abstract
A correlation between the peak electric field and hysteresis
of a polymer-stabilized blue-phase liquid crystal (BPLC) is found experimentally.
If the peak electric field is below $\sim
~5 V/μm, hysteresis is negligible. Based
on this guideline, we propose elliptical protrusion electrodes to reduce peak
electric field which in turn eliminates hysteresis while keeping a high transmittance.
Such a hysteresis-free BPLC device is highly desirable for display and photonic
applications.
