Abstract
In this article, we disclose a field sequential color display based on the vertically aligned deformed helix ferroelectric liquid crystals (VADHFLCs) with enhanced Kerr constant (KKerr). The KKerr for VADHFLCs strongly depends on the pitch (p0) and spontaneous polarization (Ps) of the ferroelectric liquid crystal (FLC) material. The longer pitch results in higher KKerr, but simultaneously provides a poor dark state and slower optical switching, therefore, a tradeoff exists here. A new FLC material has been developed to serve the device requirements. The KKerr of 104 nm/V2 has been achieved that provides response time ~300 μs at the electric field of 1 V/μm. Thereafter, the developed VADHFLC is deployed to a field sequential color display with a driving frame frequency~300 Hz.
