Alphanumeric displays!

You guys already carry 7 segment displays, but something similar to this would be awesome too!

Can't seem to find 0.4'' like these on Digikey...

Why 14-segment

Post by Yvan256 » Fri Nov 27, 2009 9:04 am

If you're asking for a ready-made PCB with such displays, why not ask for 16-segment displays instead?

What would really be neat is dotmatrix-based displays that don't cost a fortune and only require a few data lines to display stuff (serial data in with latches, i.e. 1 bit = 1 dot maybe?)

A search for "alphanumeric" on Sparkfun
( https://www.sparkfun.com/search/results ... phanumeric )
seems to show that they used to sell lots of different kinds of alphanumeric LED displays
and a "Serial Alphanumeric Display Driver", but they are all retired.
Like jeanseb, I am surprised that at the moment Sparkfun apparently doesn't carry *any* alphanumeric displays.

I see that Adafruit has a bunch of end-to-end stackable alphanumeric 14-segment LED backpack boards in a variety of colors that
share the power and I2C control wires and have electronics to drive each LED appropriately,
and also the raw 14-segment "digits" on those boards available separately.
( http://www.adafruit.com/search?q=alphanumeric )

Mouser also resells those same backpacks from Adafruit,
( http://www.mouser.com/Tools-Supplies/Ac ... ay&FS=True )
, as well as a wider array of raw alphanumeric "digits".
( http://www.mouser.com/Search/Refine.asp ... ic+display )
apparently including exactly the
Kingbright ACPSA04-41SRWA 0.4" single digit alphanumeric LED display
http://www.mouser.com/Search/Refine.asp ... A04-41SRWA
mentioned in the first post on this thread.

Yvan256: I agree that dotmatrix-based displays that require only a few data lines to display stuff are really neat.
When I search Sparkfun for "LED button pad",
https://www.sparkfun.com/search/product ... button+pad
I see a few items that seem to meet that criteria.
When I search Sparkfun for "dot matrix"
https://www.sparkfun.com/search/product ... dot+matrix
I see many other items that seem to meet that criteria.

We had looked into the Kingbrights a few years ago, but then they were really cost prohibitive (I think I remember a price of around $5 per unit).

It looks like they've gone down in price and it might be worthwhile to talk to them again. As others have pointed out, we once sold alphanumeric displays, but we weren't selling enough to justify keeping up with production of the serial driver board.
