Optional filter
The luminance contrast of the ICE version of the display EL640.400-CD3 is sufficient for
operation without any contrast enhancement. An anti-reflective coating or a protecting sheet
with anti-reflective treatment is recommended. For the best overall performance of the
EL640.400–C2 and -C3, a neutral gray circular polarizing filter with anti-reflective coating or
etch is the usual choice. This filter will make the reflective electrodes of the display darker
and improve the contrast ratio. The anti-reflective coating on the filter should face the user.
