Abstract

We report an optimized transmissive fringe-field-switching (FFS) liquid crystal display (LCD) employing a low viscosity nematic mixture ZOC-5322. Submillisecond average gray-to-gray (GTG) response time is achieved at 40 °C by using a two-step overdrive and undershoot driving scheme. Such a fast response time enables field-sequential-color (FSC) operation to mitigate color breakup. By removing the lossy color filters, such an FFS LCD triples the resolution density and optical efficiency to fulfill 1-arcminute visual acuity and low power requirements of virtual reality (VR) headsets. Moreover, our optimized non-virtual-wall FFS cell exhibits a 1.64x faster average GTG response time and ∼ 6% higher transmittance than those of conventional virtual-wall counterparts.
