FSTN LCD Display Glass Panel

The most recent advance has been the introduction of Film
compensated Super Twisted Nematic (FSTN) displays. It adds
a retardation film on the STN display that compensates for
the color added by the birefringence effect. This enables a
black and white display to be produced and provides for a
higher contrast and wider viewing angle.
The FSTN technology comes in a single coloration, Black characters
on a White Gray background. Among the three technologies listed
here, it is the most expensive one, but it has better viewing
angle and contrast than the STN technology listed above.
