Journal ArticleDOI
Two-dimensional liquid crystal polarization grating via linearly polarized light modified multi-beam polarization interferometry.
Yue Shi,Yingming Lai,Yan Jun Liu,Vladimir G. Chigrinov,Hoi Sing Kwok,Minggang Hu,Dan Luo,Xiao Wei Sun +7 more
TL;DR: A linearly polarized light (LPL) is introduced into a three-CPL interference configuration to improve the interference field and fulfill the critical requirement of full coverage of light intensity and well photoalignment defined LC directors.
Journal ArticleDOI
12.4: Distinguished Student Paper: Passive-Matrix-Driven Field-Sequential-Color LCD
TL;DR: In this paper, a fast liquid crystal display mode is demonstrated, which is based on a stressed splay twist deformation and can be driven in passive matrix or active matrix manners.
Proceedings ArticleDOI

Ben Zhong Tang,Wing Yip Lam,Xiangxing Kong,Priscilla Pui Sze Lee,Xinhua Wan,Hoi Sing Kwok,Yuan Ming Huang,Weikun Ge,Hongzheng Chen,Ruisong Xu,Mang Wang +10 more
TL;DR: In this paper, a large number of new polyacetylenes with general molecular structures of -[HC equals C(C6H4-mesogen)]p- [poly(arylacetylene) type] and -{HC = C[(CH2)n)-mesogen]p-[poly(alkylacetylene] type] are designed and synthesized.
Journal ArticleDOI
High quality YBa2Cu3O7 films on polyalumina
TL;DR: In this paper, superconducting YBCO (YBa2Cu3O7) films were deposited on polycrystalline alumina substrates with c-normal orientation.
Journal ArticleDOI
78.1: Ultra Compact Polarization Recycling System for White Light LED based Pico‐Projection System
TL;DR: In this article, an ultra compact polarization recycling system for white light LED based projectors is proposed, where the light with non-useable polarization state will be reflected back and concentrated right on to the phosphor surface.
