Optically optimized transmittive and reflective bistable twisted nematic liquid crystal displays

Shu Tuen Tang, +2 more
- 15 Jan 2000 - 
TL;DR: In this paper, a new Mueller matrix approach is developed for the design of optical modes for all nematic liquid crystal displays (LCD), and conditions for linear polarization and circular polarization outputs are obtained.
Journal ArticleDOI

Growth Methods, Enhanced Photoluminescence, High Hydrophobicity and Light Scattering of 4,4 '-bis(1,2,2-triphenylvinyl)biphenyl Nanowires

Shuming Chen, +4 more
- 01 Oct 2012 - 
TL;DR: In this paper, self-assembled 4,4′-bis(1,2,2-triphenylvinyl)biphenyl (BTPE) nanowires have been facilely grown by either post-annealing its vacuum-sublimed amorphous film or slowly evaporating its chloroform solution.
Journal ArticleDOI

Extended Jones matrix method for oblique incidence study of polarization gratings

Li Tan, +2 more
- 31 Jul 2012 - 
TL;DR: In this article, a fast and accurate extended Jones matrix method for characterizing the transmitted field of polarization gratings at oblique incidence is reported, where the far field diffraction properties of the mth order of the grating are determined by vectorial Fourier coefficients of the transmitted fields.
Journal ArticleDOI

Electrically/optically tunable photo-aligned hybrid nematic liquid crystal Dammann grating

Xiaoqian Wang, +6 more
- 15 Dec 2016 - 
TL;DR: The fabricated polarization independent DG generates an optical array of equally distributed energy, which is characterized by a diffraction efficiency of more than 58%, a response time <1 ms, and the driving voltage 3 V/μm.
Journal ArticleDOI

New bistable twisted nematic liquid crystal displays

Zhiliang Xie, +1 more
- 19 Jun 1998 - 
TL;DR: In this article, the authors developed new bistable twisted nematic (BTN) displays that operate between the −π/2 and 3π/ 2 twist states and between the π/ 2 and 5π/ 1 twist states.
