A low-power, wide-view, and single-cell-gap transflective display using a polymer stabilized blue-phase liquid crystal
(BPLC) is proposed. To reduce operating voltage, we use protrusion electrodes to generate strong fringing fields to
penetrate deep into the bulk liquid crystal layer. To balance the optical phase retardation between transmissive (T) and
reflective (R) regions, we design the R region with a wider electrode gap so that its smaller induced birefringence
compensates the double pass of the ambient light. To reduce power consumption, we utilize the fast-response feature of
BPLC for field sequential display which triples the optical efficiency and resolution density.
Polymer-stabilized optically isotropic liquid crystal exhibits a fairly large Kerr constant and has potential to become
next-wave display technology. The underlying physical mechanism is the Kerr-effect-induced isotropic-to-anisotropic
transition. Wavelength and temperature effect on the Kerr constant of optically isotropic liquid crystal composites are
investigated. Our experimental results indicate that as the wavelength or temperature increases, K decreases. The
proposed physical models fit very well with the experimental data.
