Description
The 18:88 0.56" Four Digit Seven
Segment Displays incorporates a
new slim font character design. This
slim font features narrow width,
specially mitered segments to give a
fuller appearance to the illuminated
character. Faces of these displays
are painted a neutral gray for
enhanced on/off contrast.
All devices are available in either
common anode or common cathode
configuration with tinted green
segments.
