Modeling parallel aligned liquid crystal devices

Abstract

The Parallel Aligned Liquid Crystal microdisplays (PA-LC) has become a widely used device for optics and photonics applications. In this work we propose a PA-LC model that allows us to predict the device performance in a wide range of incidence angles and for any wavelength in the visible. From a reduced amount of measurements we apply a reverse engineering process that reveals some important parameters related with the manufacturing of the device. This knowledge eases the design of our photonic application or experiment, and it serves us to analyze the physics and dynamics of PA-LC cells since we can infer the LC molecules tilt angle as a function of applied voltage.
