Hi,
I think this will be my 1st post, after lurking in the forums for a little while.
I was able to find this info only on this display.
-------------------------------
LR3785R
Industrial Electronic Engineers :: Segmented Alphanumeric LED Display - (8.8.)
Specsheet / Datasheet
Package Style (Basic)=2-Edge
Number of Characters=2
Connection Type=Comm Cath.
Color=Red
Character Height (mm)=14
Peak Wavelength (m)=655n
Iv Min.(cd) Luminous Intensity=250u
@I(F) (A) (Test Condition)=20m
V(F) Max.(V) Forward Voltage=2.0
@I(F) (A) (Test Condition)=20m
I(F) Max. (A) Forward Current=25m
Package=2-Edge
-------------------------------
I should soon have a couple of these. If the case is as HarveyH42 has uploaded, it would make my life even more difficult. ( I was looking at a different dual alphanumeric when I came across these.). I think I will have to do some more serious thinking, since I am only a beginner, and that would mean I must think on how to do a multiplex.
I am in the development stage of a clock, PLUS a DAY of the WEEK ;-) so if if I have to multiplex, I am thinking of using a 555 timer somehow... to be switching the electrical on and off.
Anyhow, I will post once again in this thread, for part of the circuitry that I am doing once I receive the led's and will need help
