FAQ3: Is
the reliability of liquid crystal (LC) based devices good enough
for telecom applications?
 For
decades, LC based devices have been used in the computer display
industry and demonstrated very good reliability. However, the typical
operating conditions in telecom applications are more adverse and
harsh than those in the display industry. To meet these new reliability
challenges, many efforts have made by our engineering team, including
material selection, cell assembly and device packaging, in design
and development of the LC devices. Designed to meet the Telcordia
GR-1221, a commonly accepted industrial reliability standard, our
LC-based device is currently under qualification. As of today, it
has successfully passed the temperature cycling and all mechanical
integrity tests.
