High contrast polymer-dispersed liquid crystal in a 90° twisted cell
نویسندگان
چکیده
A polymer-dispersed liquid crystal confined in a 90° twisted cell ~T-PDLC! is demonstrated. In comparison to a conventional PDLC, the T-PDLC is also polarization independent while exhibiting a higher contrast ratio. Potential applications of the T-PDLC are in polarizer-free reflective display and light switch. A black and white segmented-alphabet reflective display using a dye-doped T-PDLC is demonstrated. © 2004 American Institute of Physics. @DOI: 10.1063/1.1753052#

Nano-droplet formation in polymer dispersed liquid crystals
In this work we analyse the fabrication of Polymer Dispersed Liquid Crystals (PDLCs) using SU8-2002-2007 photoresist and 5CB and E7 Liquid Crystals. Also we report the nonlinear optical behaviour for these materials and for Polymer Dispersed Liquid Crystals with a Twisted Cell (T-PDLC). We found that depending of several parameters, the droplets size varies from nano to micro dimensions. We rep...
متن کاملLiquid Crystal Lattice Models Ii. Confined Systems
Monte Carlo simulations of lattice spin models represent a powerful method for the investigation of confined nematic liquid crystals and allow a study of the molecular organization and thermodynamics of these systems. Here some models of confined liquid crystals, such as polymer dispersed liquid crystals, twisted nematic, in-plane switching liquid crystal displays and hybrid aligned films are d...
متن کاملPower generating reflective-type liquid crystal displays using a reflective polariser and a polymer solar cell
We herein report the results of a study of a power generating reflective-type liquid crystal display (LCD), composed of a 90° twisted nematic (TN) LC cell attached to the top of a light-absorbing polymer solar cell (PSC), i.e., a Solar-LCD. The PSC consisted of a polymer bulk-heterojunction photovoltaic (PV) layer of poly[[9-(1-octylnonyl)-9H-carbazole-2,7-diyl]-2,5-thiophenediyl-2,1,3-benzothi...

متن کاملOn the Electric Field Induced Stripe Instability Threshold of Twisted Nematic Layers
Most liquid crystal displays make use of the elect roopt ic properties of twisted nematic layers. Both the s tandard twisted nematic displays of 90° twist [1] as well as the recently developed 'supertwist ' displays of more than 180° twist [2] require director fields which depend only on one spatial coordinate, the coordinate z parallel to the layer normal. Director fields which depend on more ...
