Where to get 4-digit 7-segment LED with decimal points and colon 0.56" digits?

I have a design that needs 4-digit 7-segment LED with decimal points and colon 0.56" digits. I looked on ebay and there seems to be only 2 sellers that sell these (yeah, some are aliases of the same sellers). One has the wrong connection diagram. I got a sample from them and the decimal points don't work. The other seller doesn't even offer connection diagram and just claims all the dots work. Should I trust them? I also looked at digikey and sparkfun but they don't have large enough digits. If you have used such display (both decimals and colons have to work), can you suggest a source of this display? Thanks.

My only one suggestion received from GoForSmoke:

This is common cathode and there's only one color so I wonder if there are other ones and common anode ones out there I just don't know. Thanks.

These ones look pretty close:

Just a bit small. I will have to use them if I can't find the larger ones.

Pretty hard to find the colons, I've spent more than a little time looking myself. Tayda sells some that are visually almost identical to those that Sparkfun sells, but the connection is just a bit different, and they're common cathode. But like the Sparkfun displays, they are 0.4". Both are good quality displays, very crisp and they don't need a lot of current.

I'd really like to find a part with six digits or more so I could have 88:88:88, etc., but they just don't seem to be out there. A two-digit part with a colon would also work by stacking them.

Let us know if you turn anything up.

Will do. If I find anything useful, I'll post where I get them.

these LED Display 7 Segment 4 Digit 0.56 inch Common Anode Ultra Red 21937ucd might fit what you need.


Can select common cathode or anode too when purchase. But only red.

Check out kingbright LEDs.
Whole series of common anode, common cathode, different colors.
