LED displays
High efficiency, two-digit numeric displays
LB-202BL Series
The LB-202BL series are small, two-digit numeric
displays with a character height of 6.4 mm. These
displays can be combined with appropriate displays in
the three-digit LB-203 BL series to form a multi-digit
display with an equal pitch interval between characters.
