Optional Filter 

The luminance contrast of EL320.256–FD7 is sufficient for operation without 
any contrast enhancement. An anti-reflective coating or protecting sheet with 
anti- reflective treatment is recommended. For best overall performance in 
high ambient luminance levels, a circular polarizing filter with anti-reflecting 
coating or etch is recommended. This filter will still lower the reflections from 
the display background and improve the contrast ratio. Contact Planar for 
details.
