What ever happened to red LED displays?

[[email protected]]

I have been looking for a digital thermometer and perhaps a timer,
with red LED displays (like the old MA1026 chip)
Everything is LCD these days. The only time I see somerthing with red
LEDs it is a bomb on a TV show.

LEDs use more power. That's probably why they're less popular..

We have bunches of them on eBay under abeja .

** LED displays are not suitable for small, battery operated devices - the
power consumption is far too high.

My first pocket calculator ( a scientific one bought in 1974 ) used a 12
digit, miniature LED display - but ran on Ni-Cds for about 5 hours at a go.

The LED display models were soon replaced by fluorescent and then LCD types.

LED panel meters are readily available, in 3.5 and 4.5 digit - the latter
are not cheap.

Tell that to all the original calculator manufacturers that made
millions on just such displays.

My commodore pulled .8 amps with both memories filled with 8s and the
mantissa filled with 8 even into the no viewable digits. It pulled
about .3 A with all cleared and a single 1 entered on the display.
Great calculator!

12 digit mantissa in '74 huh? OK.

Wrong. The Battery operated world never went to fluorescents with
any degree of success.

LED panel meters are readily available, in 3.5 and 4.5 digit - the latter
are not cheap.

That isn't a display, that is a meter. So yes, it will have an
attached price. It has nothing to do with the color red, however.

All the extra lines after your post is even more retarded than your
baseline retarded behavioral crap, Phil.

** Read the whole post - you ASININE CUNTHEAD.

Wrong.

** **** OFF - ASSHOLE

The Battery operated world never went to fluorescents with
any degree of success.

** But they WERE made for a while & ran off a 9 volt battery too.

That isn't a display, that is a meter.

** So fucking what - you pig arrogant ASSHOLE ?

The OP asked about multi-digit displays - ASSHOLE !!!

So yes, it will have an
attached price. It has nothing to do with the color red, however.

** Never said it did - you pig arrogant ASSHOLE !!

All the extra lines after your post ...

** Hurt nobody.

But I wish someone would track an EVIL **** **** like you down and send
you straight into HELL.

It is obvious from your post that you have no dick, so I doubt you
have any balls either.

If it is plugged into the wall why should I care about that?

** The REASON very few LED displays are seen on ordinary commercial
products, even non-battery powered ones , is that fluorescent and LCD
displays allow VASTLY more complicated and useful displays to be made than
is possible with LEDs.

Look at any VCR or mobile phone display - it has clever icons, bar graphs
and multiple alpha-numeric fonts all on ONE back lit device.

But I agree that red LED displays look great.

My bench DMM, 2 frequency counters and an AC current monitor ALL have seven
segment, red LED displays.

12 digit mantissa in '74 huh? OK.

I had one of these:

12 digit result flourescent display that ran on batteries (6 digit

types.

Uh huh.

Oops, looks like agent's kill filter works on group basis. I guess I
must make the filter work here too.

Yes, it's a great loss. In laboratory environments, where you often want
to read numbers from a distance from wide angles and under various
lighting conditions, nothing beats red or green LED, 7-segment displays.
Amber fluorescent displays are good, too. LCDs, backlit or not, are
crap.

Blue LEDs are a real pest too. Some bright guy had the brillant idea to
install clocks with 4-inch, blue 7-segment displays (the segments made
of rows of LEDs) in a local railway station. Impossible to read. I've
got 20/20 sight (with glasses) and can't read the damn things unless I'm
about ten feet away. I guess the eye has only few blue-sensitive
receptors.

Shame also on the folks at Lakeshore who think that cryogenic equpiment
calls for blue fluorescent displays.

displays allow VASTLY more complicated and useful displays to be made than
is possible with LEDs.

"Vastly more complicated" is not necessilarly a good thing.
I think the industry has abandoned a 73 million person market, the
boomers. Lots of tiny buttons and overly complicated displays are not
appreciated by folks who just want to know what time it is or what the
temperature of something is. It is much like the "Microsofting" of
computers where we have taken basic text mode applications and added
100 meg of unneeded graphics, for no particular reason..

Special effects designers...yes indeed. If you want to see the way these
guys think, check out Mythbusters on the Discovery Channel sometime.
After seeing their can-firing treaded combat vending machine, I feel as
if I'm in the wrong line of work.

Thanks Jim. I did eventually find that .
