Contrast Enhancement
The objective of contrast enhance ment is to optimize
dis play readability. Adequate contrast enhancement can
be achieved in indoor applications through luminous
contrast techniques. Luminous contrast is the observed
brightness of the illuminated segment compared to the
brightness of the surround. Appropriate wavelength filters
maximize luminous contrast by reducing the amount of
light reflected from the area around the display while
transmitting most of the light emitted by the segment.
These filters are described further in Application Note
1015.

Chrominance contrast can further improve display read-
ability. Chrominance contrast refers to the color difference
between the illuminated segment and the surrounding
area. These displays are assembled with a gray package
and untinted encapsulating epoxy in the segments to
improve chrominance contrast of the ON segments.
Additional contrast enhancement in bright ambients may
be achieved by using a neutral density gray filter such as
Panelgraphic Chromafilter Gray 10, or 3M Light Control
Film (louvered film).
