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<p><img loading=\"lazy\" width=\"782\" height=\"1012\" src=\"https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1.jpg\" class=\"cleaned-enfold-image\" alt=\"\" decoding=\"async\" loading=\"lazy\" srcset=\"https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1.jpg 782w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-232x300.jpg 232w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-768x994.jpg 768w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-545x705.jpg 545w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-29x37.jpg 29w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-43x55.jpg 43w, https:\/\/silvaco-stage.betagentechnologies.com\/wp-content\/uploads\/2020\/02\/simstd_Q3_2017_a2-1-37x48.jpg 37w\" sizes=\"auto, (max-width: 782px) 100vw, 782px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Liquid Crystals (LCs) are widely used in the display technology due to the property of optical birefringence.
