LCD Panels

Tn displays have 90° or less twist (the rotation of the molecules from one plane of the display to the other). All passive direct drive, active matrix, and most passive low level (x2 to x32) multiplexed lcds have a 90° twist. the basic twisted nematic (tn) lcd consists of a layer of liquid crystal material supported by two glass plates. The liquid crystal material is a mixture of long, cylindrically shaped molecules with different electrical and optical properties, depending on direction.
