Model-specific replacement risks
Pins 37–40 are NC. The reviewed AT043TN24 V.7 uses these positions for X1/Y1/X2/Y2 touch electrodes and has a different listed thickness. A shared connector recommendation is not a drop-in approval.
Validate the complete V.2 pin map, DE/clock timing, host logic thresholds and LED current. Do not replace TBD entries with estimates or values copied from a neighboring model.
Do not wire from this summary. Use the complete connector drawing, pin table, timing limits and power sequence for the exact panel and host. Absolute maximum electrical ratings are not recommended supply settings.
Before ordering a sample
- Record the complete model suffix and match the applicable document revision.
- Compare connector orientation, every pin assignment, supply rails and signal thresholds.
- Verify host timing, display-control behavior and separate backlight requirements.
- Check the enclosure, FPC routing, viewing direction and any touch assembly.
- Validate a sample in the intended equipment before production approval.
Frequently asked questions
Is this a final or complete current specification?
No. The supplied copy is marked Preliminary, Version 01, dated 2010-05-14. It contains 20 PDF pages, while body footers use a 22-page total and the supplied copy ends at printed page 17. Obtain the complete applicable document before design approval.
Does this guide confirm an interchangeable replacement?
No. It reports a specific document scope and review risks. Approve a candidate only after comparing the complete panel and host documentation and validating a sample.
What should I provide for a quotation?
Send the full panel label, required quantity, destination, application, controller and cable details, and whether touch or enclosure changes are permitted. Ask for the applicable current specification and supply status.
