Liquid Crystal on Silicon Diffractive Light Valve

KSU.236

Abstract: Desired high resolution, high brightness and high contrast liquid crystal on silicon (LCoS) displays have been pursued by many researchers and many methods.  This advantageous method uses alignment controlled polymer wall technique forming a liquid crystal diffractive light valve to modulate the polarized light, which the inventors have called a Polymer Wall Diffractive LCoS (PWD-L-CoS) device.  When PWD-LCoS is applied in a Schlieren optical system, the high resolution and high brightness can be realized.

Applications:

•           Projection displays;
•           Optical beam steering;
•           Light intensity modulation;
•           Electro-holography;
•           3-D television

Advantages:

•          High brightness
•          High resolution projection
•          Lower driving voltage (low voltage being very important for LCoS applications)
•          Increased switching speed
