STN (Super-Twisted Nematic) LCD has quite a long development history, it requires less power and is less expensive to manufacture than TFT LCD. With the addition of a retardation film on top to the STN LCD (known as FSTN) that compensates for the color added by the birefringence effect, will allow FSTN display with better black and white color and provides for a higher contrast and wider viewing angle. With the RGB color strips properly made inside the FSTN display, through external white backlighting, to generate the full colors effect, it becomes a color STN (CSTN) display. | |
| Because of its maturity and its low fabrication cost, STN LCD technologies is still popular used for the display market of most portable applications such as industrial and medical instrumentation and many other products that require small-medium size display.
