Film Compensated Super Twisted Nematic (FSTN)
Film Super Twisted Nematic fluid is more expensive than STN and offers a sharper contrast than TN and STN.
Contrary to STN Indicators, Retardation film added to polarizers reduces the Contrast and Angle loss on the STN LCD indicators to a minimum. Especially with backlight FSTN LCD Display image quality, much better than STN LCD Displays. The segments are darker (almost pure black) and the viewing angle is wider.
