zFeatures
1) 10.16mm 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.

LAP-401 D / N 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.
