Submillisecond-Response Sheared Polymer Network Liquid Crystals for Display Applications

Abstract

A 4 phase modulator with an average gray-to-gray response time of 400 s is demonstrated based on sheared polymer network liquid crystal (SPNLC). This device exhibits a low scattering at 532 nm due to our new material set and shearing technique. We also discuss the application of SPNLCs for 3D display, such as lenticular lens.Index Terms-Fast response, lenticular lens, liquid crystals (LCs), sheared polymer network liquid crystal (SPNLC), 3D display.

Fast-switching initially-transparent liquid crystal light shutter with crossed patterned electrodes

“…[5][6][7][8][9][10][11][12] These light shutters are switchable between their transparent and translucent (or opaque) states by scattering (or absorbing) the incident light. The translucent or opaque state can be used to increase the visibility of a see-through display, whereas the transparent state can be used to view the background together with the displayed images.…”

Reconfigurable fabrication of scattering-free polymer network liquid crystal prism/grating/lens

“…The response time of a nematic LC is mainly governed by the cell gap, visco-elastic constant of the employed LC material, and voltage. 14 For a LC lens with 30-lm cell gap, the response time is in the order of 1 s. 15 To shorten response time, thin cell with a high birefringence LC material, 16 overdrive and undershoot voltage method, 17,18 and polymer network liquid crystal (PNLC) [19][20][21][22][23][24][25] have been investigated, just to name a few. For a PNLC containing 6-7 wt.…”
