Largest 7-seg LED displays?

[Rich Grise]

Where do bus companies get those EM marquee things?

Who makes Jumbotrons?

How about those "You are going xx miles per hour" displays
they sometimes put in lieu of a speed trap? They've got
a pretty sizeable display, if you can find out how makes/
sells them. Maybe check with your local cop shop.

Good Luck!

2" high is large as panel meters go.

I doubt that, because I have seen a great deal of 4", 6", and even 8"
panel meters on the market. In fact, your local repair garage likely
has quite a few of these on their diagostic and wheel alignment
systems.

Perhaps you don't really mean a "panel meter"?

I think he wants digital panel meters with 2" high seven segment
displays.

Some years ago, I designed some with 3" displays but we found the
marketability to not be all that great. It's one of those things that
a lot of people *say* they want but when you go and make one, and
figure out how much it costs, many lose interest. There are up to
200mm (8") displays available, but the MOQ $, power required, PCB cost
and the housing cost goes up pretty fast at those sizes (with the
square of the height). Of course if you're actually into making
scoreboards..

Sony. They are actually Braun tubes (CRTs) without deflection, IIRC.

Some of the road-work signs are now huge LCDs with fluorescent
backlighting (like 4' tubes rather than those wimpy CCFL lamps).

2" high is large as panel meters go. If you know where I can get them
off the shelf and cheap then I'd be interested in buying some. My
customer
turned down the Ł500 quote.

OKAY... Put together a RFQ and ---
Send to: astromation@pacbell.net

They will quote in USD. From what you suggest here, Less than $862 USD
How much? Fill in the data!

Tried that. As manufacturer they would only quote for an MOQ of 50 units.
As and end user we only need a few. Hence the remark "off the shelf".
There's the rub.

Sorry, knew they had built them, I also thought they had a few left! We
bought 200 for one project and 26 for another, I heard they had 24 left....
Two years back, SO?
