Liquid Crystals (LCs) are widely used in the display technology due to the property of optical birefringence. Being sandwiched by two crossed polarizers, an LC medium will work as a light switch in the existence of external electric field. We have demonstrated in a previous article the simulation of LC director variation with applied bias voltages [1]. In this article, we will show the calculation of light transmission through an LC cell including a uniaxial LC layer by an optical simulation.<\/p>\n
Simulation Basics<\/strong><\/p>\n Different polarization components of the incident light will have different phase velocities when passing through a birefringent LC medium. The resultant phase retardation determines the optical transmission of the LC film. In Clever LCD, the propagation of the s and p polarization of the incident light is calculated by the extended Jones matrix method (2 \u00d7 2 methods) described in Ref. [2]. The 2 \u00d7 2 method is capable of treating the transmission of off-axis light in a general birefringent network, therefore is not limited to normally incident rays. It is worth mentioning that the 2 \u00d7 2 method does not take into account the effect of multiple reflections between layer interfaces. Normally, the effect of multiple reflections is negligible for most practical LCD systems.<\/p>\n Liquid Crystals (LCs) are widely used in the display technology due to the property of optical birefringence.
