Double-layer STN (obsolete). Now replaced by retardation film ion on STN panel.
A passive matrix LCD technology where two separate LCD plates are combined to form a single panel for improved image quality and contrast. See also STN (Single Twist Nematic), TSTN (Triple Super Twist Nematic), and Passive Matrix LCD.
or Dual Scan Twisted Nematics, is a variation of the Passive Matrix LCD technology. Rather than having each transistor control an entire line, the transistor matrix is cut in half and the number of transistors is doubled, enabling each matrix to control only half the screen. By taking this approach, manufacturers can increase the refresh rate, offer slightly better contrast ratios, limit the ghosting, and richer colors. The drawbacks are: if a single transistor fails a dark line will appear halfway across the screen, and the cost approaches that of the Active Matrix, making any cost savings negligible.
Double Super-Twisted Nematic
Dual Scan Twisted Nematic: An upgrade to the STN type of LCD displays. It uses two display layers, which helps correct some of the problems found in a normal STN display.
Double Super Twist Nematic. A process where two separate LCD plates are combined to form a single panel.
An advanced form of passive matrix screen technology that results in high-quality monochrome and color LCDs with better contrast than previous passive displays technologies.
Double Super Twisted Numatic (DSTN) has the following features: negative and positive mode; transmissive and transflective mode; automotive specification (-30°C to +85°C); colour neutral; excellent performance with all backlight systems. See also FSTN, ASTN and CSTN.
