Optimization of one-polarizer reflective LCDs with phase compensator

New approach to optimization of reflective LCD, based on "Polarization Transformation Efficiency" (PTE) conception, is presented. This approach is used for optimization of one-polarizer RLCD in RTN mode. We have found the conditions, which enable to realize perfect dark and bright states in RTN-LCDs with a phase compensator between the polarizer and LC cell. We believe that the proposed new method of LCD optimization can be successfully applied for the definition of the new advanced LCD configurations with a high brightness, contrast and duty ratio

Liquid crystal devices for optical communication systems

Liquid Crystals (LCs) prove to be the basic material for various applications in Electronic Imaging and Displays as well as Optoelectronics. We will review the following LC optoelectronic devices for optical communication systems. 1. Fast reliable low power optical switches. We shall demonstrate the new possible configurations of the fast LC shutters for fiber-optical system, based on (i) STN-LCD cell and (ii) fast deforined -helix ferroelectric liquid crystal (DHF-FLC) mode. 2. Passive elements of optical communication systems. The software for optimization of the LC light modulation characteristics has been developed. The new photo-aligning technology for efficient LC applications in optical communication systems has been made. 3.Passive fiber optical elements based on Photonic Crystals (PCs) and Liquid Crystals (LCs). A method for the formation of controllable PC/LC structures, based on multiple-redrawing technique, applied for different types of glass, filled with photo-aligned LC is discussed
