Optional Filter
For best overall optical performance of the display, 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 will improve
the contrast ratio. The anti-reflective coating on the filter should face the user.
