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.
