Abstract
Electrode dimension effects on the electro-optic properties
of a polymer-stabilized blue-phase liquid crystal (PS-BPLC) are
investigated experimentally. By reducing the width and gap of the
in-plane-switching (IPS) electrodes, the operating voltage of the
PS-BPLC is decreased significantly while keeping over 80%
transmittance. This unexpected high transmittance results from
fringing field migration into the electrode region, which in turn
activates more BPLC material and enlarges the aperture ratio.
Further reducing electrode dimension to 2 μm would cause some
undesirable effects, such as increased response time and hysteresis
due to electrostriction effect and phase transition, and ultimately
damage the polymer networks.
