Journal ArticleDOI
High-performance polycrystalline silicon thin-film transistor technology using low-temperature metal-induced unilateral crystallization
Man Wong,Hoi Sing Kwok +1 more
TL;DR: Low-temperature metal-induced unilaterally crystallized polycrystalline silicon thin-film transistors have been developed and characterized and have been used to realize active matrices for liquid–crystal (LC) and organic light-emitting diode (OLED) flat-panel displays.
Journal ArticleDOI
44.3: A Liquid Crystal Lens with Non‐uniform Anchoring Energy
TL;DR: In this article, a tunable liquid crystal lens with a uniform cell gap, uniform applied voltage and non-uniform anchoring energy was studied and the optimal parameters of such a lens were found and discussed.
Journal ArticleDOI
Exotic Property of Azobenzenesulfonic Photoalignment Material Based on Relative Humidity
Yue Shi,Yue Shi,Yue Shi,Chenxiang Zhao,Jacob Y L Ho,Valery V. Vashchenko,Abhishek Kumar Srivastava,Vladimir G. Chigrinov,Hoi Sing Kwok,Feng Song,Dan Luo +10 more
TL;DR: The transition from amorphous solid at low relative humidity to semicrystal at high relative humidity provides a new perspective of understanding the hydrophilic photoalignment materials.
