(1) (Double layer STN) A supertwisted nematic (STN) passive LCD display that is used in high-temperature environments. A second, but inactive, LCD layer functions like the film in FSTN, except that the layer's optical properties change at the same rate as the working layer. See FSTN and LCD types.|
(2) (Dual scan STN) An earlier passive matrix display method that enabled higher laptop resolution by addressing two modules simultaneously. For example, two 240-line passive matrix subsystems were used to create one 480-line screen. See FSTN and LCD types.
