ROHM LAP

Single Digit LED Numeric Display
LAP-601 B / L Series
LAP-601 B / L series are the numberical display units
featuring ROHM’s in-house 4-element(AlGaInP)
high-brightness LED dies.Their luminous intensity is top
class in the industry while degradation is considerably slow,
which helps to keep illumination vividness almost unchanged
and the image of sets high over a long period of time.

Features
1) 14.6mm for letter height, single-line LED numerical 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 cathode common type are
available in lineup for each color.
