 Twisted nematic field effect

Twisted nematic field effect refers to a configuration commonly used in liquid crystal displays (LCDs) that involves a specific arrangement of liquid crystal molecules. In particular, the "twisted nematic" (TN) structure is characterized by the orientation of liquid crystal molecules being twisted at an angle across a thin layer of liquid crystal material. Here's a breakdown of the concepts involved: 1. **Liquid Crystals**: These materials have properties between those of liquids and solid crystals.
