A043FTN03.0 LCD Selection and Compatibility Guide

This 4.3-inch RGB panel requires a 45-pin connection and separate review of analog supply and digital-interface supply. Do not select a replacement solely from its 480 × 272 resolution or outline.

Model-specific replacement risks

The recommended connector is 45-pin, unlike the 40-pin G043FTN01.0 and AT043 models reviewed in this set. A shared 105.5 × 67.2 mm outline is not evidence of electrical interchangeability.

Check VDD and VDDIO separately and match host logic levels to VDDIO. Review DCLK, DE, DISP and UD behavior. Pins marked reserved or NC are not permission to connect an arbitrary touch controller.

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

Does the reserved touch-pin area mean touch is included?

No. The reviewed pin table marks pins 37–40 as NC and reserved for touch. Confirm the actual supplied assembly and quotation scope rather than treating these pins as an installed touch function.

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.
