... or does it?

In our products, we are using character LCDs (with backlight) of the two most common size, the one with ~5mm character height and the one with ~8mm character height.

Because of stocking reasons we were using the 1x16 pin LCD types but we got sick of the cable assembly and we thought to move on to the 2x8 pin types.

The problem is that our local distributors say there is no large 2x16 LCD with 2x8 pins and that's what we need most!

After some research
http://www.crystalfontz.com/prod... ,
digikey etc...
it seems to be true.

So I'm asking, has anybody actually seen a large 2x16(1602) LCD with double row pins(2x8)?
Am I missing something?

Maybe it is because they think that the high backlight current cannot pass via the 0.05" pitch cable?

By "large" do you mean just "2x16", or do you mean the bigger-sized characters? [I'm now working with a x20 that is 145mm wide with 10mm charcter height.] I'd guess that single-row is used to keep the module size down; the single row on one edge (the top in all I've seen) doesn't require "stretching" the width as would be needed for a 2x connector.

At NewHaven http://www.newhavendisplay.com/i... the 2x16 seem to be nearly all single-row. However, for example, there are a couple of models that come with ribbon cable

We use a lot of Varitronix (or drop-on equivalent) in production for 2x16 & 2x20, and Hantronix (or equivalent) for 2x8. All are the "standard" ~5mm character height and have 2x connector on the [left] side. It does seem from catalog pages that when you go to the ~10mm character height that the connector is single-row, top or bottom.

By "large", I mean those with a character height of 8..10mm.
For example, I have this one in my bench:
www.sdec.com.tw/downloadfiles/20...
which is 9.66mm char Height (large) but single row pins.
And I don't see what I'm looking for in their site either... http://www.sdec.com.tw/products.... .

I don't believe that they don't want to stretch the PCB. They do it for the smaller(~5mm) 2x20, 2x16 LCDs. It could be done in the above LCD without stretching at all. It fits and I would help a lot in the assembly process if we only had to crimp a couple of 2x8 IDC headers on a flat cable.

you can just solder pinheaders to the lcd 1x16 pin header and use an 2x17 idc to connect the lcd to your pcb.

This solution is good for home projects but the boss wants professionally looking products.
We are using single row headers/connectors with 0.100" pitch flat cables and proper crimp tools but the 2x8 IDC would be better.

DOGM series maybe? 2 rows of 20 pins at .1 inch spacing.

Looks like they also have several versions in PDIP mounting which looks like it might be exactly what you want.

DOGM series seems to be for mounting directly on PCB.

In the entire product line, the closest I found was a 2x20 chars module with 9,7mm char height (model EA P202-B3HNLED).
Nothing at 2x16 chars!
