Single Digit LED Numeric Display
LAP-601 B / L Series
LAP-601 B / L series are the numberical display units Dimensions (Unit : mm)
featuring ROHM’s in-house 4-element(AlGaInP)
high-brightness LED dies.Their luminous intensit y is top
class in the industry while degradation is cons iderably slow,
which helps to keep illumination vividness al most unchanged
and the image of sets high over a long perio d of time.
Features
1) 14.6mm for letter height, single-line LED n umerical displays.
2) About 10 times more luminous intensity than the
conventional products by use of 4-element LED dies.
(in case of orange color)
3) The same luminous intensity as the conventional products
at their 1/10 of current, which contributes lots to
energy-saving of sets.
4) Light-leakage from segments probable with the small
display packages is very rare.
5) Both anode common type and cathod e common type are
available in lineup for each color.
