AT043TN24 V.7 LCD Selection and Compatibility Guide

This reviewed V.7 configuration explicitly includes a touch-screen panel with a 3-in-1 FPC. Review the display, backlight and analog touch connections together; a non-touch 4.3-inch module is not an equivalent assembly.

Reviewed document: Preliminary specification, Version 01, A043-24-TT-71; document date 2010-04-19; customer field CNSBG. Approval dated 2010-04-24.

Model-specific replacement risks

The reviewed AT043TN25 V.2 lists 2.9 mm thickness and NC at pins 37–40; this V.7 document lists 4.05 mm and touch electrodes at those pins. Neither mechanical fit nor touch compatibility can be assumed.

Confirm the touch controller supports the documented analog electrodes and the actual cable routing. Review bezel clearance, touch activation and calibration along with image timing, power and backlight performance.

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

Can I substitute a non-touch AT043TN25 V.2?

Not as an assumed unchanged replacement. The reviewed V.7 assembly has touch-electrode pins and a 4.05 mm module depth; the V.2 document lists those pins as NC and a 2.9 mm depth. Review the complete system and sample before 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.
