WebJan 20, 2024 · The fundamental principle of twisted nematic (TN) displays is the use of liquid crystals to control the passage of light. Liquid crystals are a special type of material that has properties of both liquids and solids. They can flow like a liquid, but they also have a specific alignment of molecules, similar to a solid. WebTwisted-nematic liquid-crystal devices having high spatial resolution are suitable for spatial light modulators. Phase-modulation characteristics of the devices have been widely studied, but the phase delay calculated using a conventional Jones-matrix model is slightly different from that measured using an interferometer.
