TN (Twisted Nematic)

A type of LCD panel technology. In this type of panel, when no electric current is running through the liquid crystal cells, the cells naturally align in a twisted form between two substrate panes of glass which blocks the transmission of light from the backlight. This renders the crystals opaque and results in a black display screen. When an electric current is applied, the liquid crystal cells untwist allowing light to pass through resulting in a white display screen. TN panels have relatively narrow viewing angles especially in the vertical direction and color reproduction is poor; however, they are economical and suitable for a wide-range of general uses, particularly with office tasks (e.g. word processing).
