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.

Flat-panel display technology has been developing extremely rapidly, the main advantages of STN over other display technologies is the relatively easy and economic that the display content can be customized to satisfy the specific requirements of an application. EDT is keeping the R&D resource to support our customer’s need for their future STN LCD designs.
