Heart of the Technology is the liquid crystals (LCs)
LCs are rod like molecules with a negative and positive end. LCs rotate the plane of polarized light.
Twisted Nematic (TN) displays rotate the director of the liquid crystal by 90deg
Super-twisted nematic (STN) displays employ up to a 270deg rotation. Main benefit is wider angle viewing.
LCDs can be Passive Matrix (PM) or Active Matrix (AM)
