From question to production, with an engineer on every step
Most display suppliers sell catalogs. We start with your design constraints and only then recommend a panel.
- 01Tell us the constraints
Size, interface, host processor, environment, volume.
- 02Options within 12 hours
2–3 recommended modules with datasheets and init code.
- 03Samples from 1 pc
Bring-up support until the panel lights up on your board.
- 04Stable volume supply
Long-term supply, EOL notice and drop-in alternatives.
Your panel went EOL. Your product didn’t.
Search a part number to see its lifecycle status and our drop-in, FPC-adapter or mechanical-change alternatives, with differences spelled out.
