TFT - LCD Technology for Context
Comparison with Semiconductor Manufacture
Liquid Crystal Display
Thin Film Transistor (TFT)
Liquid Crystal Display (LCD)
Active Matrix LCD
Passive Matrix LCD
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)
