Works, thanks!!!

Great to see how you are following through with this, Robert!

But I am also impressed by the professional support provided by your "supplier B", DDX. You are getting good value for your 320$ tooling and NRE fee. If the final product is as convincing as the dialog to plan and specify it, the result should be really neat!

Last round of changes are in, and it's looking good! I signed the first page and sent it back, and now we wait 4-6 weeks for the samples!

I have learned:

1. Sending a multi-page spec is better than a single page.
2. Using a matrix for the pins instead of a pinout is apparently standard for LCDs.
3. Don't spell anything else out in tables. Put all the measurements on the drawings.

Even if the final product is junk, there's probably $320 worth of education in this thread. Prior to this I had no idea custom LCDs were even remotely feasible in volumes less than tens of thousands.

krasin:
This. I am surprised that getting a custom LCD is projected to be cheaper than a custom injected molded case.

I really hope this project succeeds and the experience is documented, so that others can follow.
