P‐133: Variable Liquid Crystal Pretilt and Azimuth Angle Using Stacked Alignment Layers
TL;DR: In this paper, a new alignment layer is developed, which is capable of generating arbitrary pretilt and azimuth angles for the liquid crystal, based on stacking both photo-aligned polymer and rubbed polyimide together.
Journal ArticleDOI
The collisionless IR absorption spectrum of C3F7I
Pritish Mukherjee,Hoi Sing Kwok +1 more
TL;DR: In this article, the collisionless infrared absorption spectrum of C3F7I was measured with an 80 ns CO2 laser system and the collisional broadening contribution was found to be much larger than anticipated.
Journal ArticleDOI
A Reduced Mask-Count Technology for Complementary Polycrystalline Silicon Thin-Film Transistors With Self-Aligned Metal Electrodes
TL;DR: In this paper, a technique based on aluminum-induced crystallization of amorphous silicon has been applied to fabricate TFTs with low-resistance self-aligned metal electrodes (SAMEs).
Journal ArticleDOI
Nanostructured alignment layer for liquid crystals
TL;DR: In this paper, a new type of nanostructured alignment surface is proposed and demonstrated, and a large pretilt angle of near 45° can be produced reliably with no randomness involved.
Bistable twisted nematic liquid crystals display with permanent grayscales and fast switching
TL;DR: In this article, a π bistable twisted nematic liquid crystal display with permanent grayscales has been demonstrated, which can be switched between −22.5 and 157.5° twist states by means of a combination of strong in-plane electric fields and vertical electric field for creating both the planar anchoring breaking and an electrohydrodynamic flow.
