Single Digit LED Numeric Display

LAP-401 D / N Series

LAP-401 D / N series are the numberical display units



Dimensions (Unit : mm)

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) 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.
