Innolux AT043TN25 V.2 4.3inch LCD Panel
Innolux AT043TN25 V.2 4.3-inch WQVGA TFT-LCD Specifications
The Innolux AT043TN25 V.2 is a 4.3-inch 480 × 272 WQVGA TFT-LCD module with a normally-white, transmissive display and a 40-pin digital RGB interface. The final approval specification, Version 0.7 dated December 18, 2023, lists 500 cd/m² typical luminance (400 cd/m² minimum) and a 500:1 typical contrast ratio (400:1 minimum). Confirm the complete module label, pin assignment, and current revision before design approval.

Selection and integration notes
- Use 500 cd/m² as the typical luminance and 400 cd/m² as the minimum. The same distinction applies to contrast: 500:1 typical and 400:1 minimum.
- The recommended LCD connector is a 40-pin FH19SC-40S-0.5SH. Check every signal, supply, ground, and no-connect pin against the specification before designing or adapting a cable.
- The interface uses parallel digital RGB signals. Verify the RGB timing, display-enable signal, clock, power sequence, and 3.3 V logic supply with the controller.
- The reviewed final LCD specification does not describe an integrated touch panel. If touch input is required, confirm the separate touch assembly, controller, mechanical stack-up, and electrical interface.
- The stated 20,000-hour LED life is a typical value defined at 25 °C and 20 mA to 50% of initial luminance; it is not a general service-life guarantee.
- The 2023 specification does not establish present stock, production status, or lead time. Confirm current availability and the revision supplied for your project.
Frequently asked questions
What are the brightness limits of AT043TN25 V.2?
The final specification lists 500 cd/m² as typical luminance and 400 cd/m² as the minimum.
What display interface and connector does it use?
It uses a 40-pin digital parallel RGB interface. The recommended FPC connector is Hirose FH19SC-40S-0.5SH. Verify the full pin assignment and timing before connection.
Does AT043TN25 V.2 include a touch panel?
The reviewed final LCD specification does not describe an integrated touch panel. Request the exact touch assembly and its interface separately if touch input is needed.
What are the operating and storage temperature ranges?
The specified operating range is −20 to +70 °C, and the storage range is −30 to +80 °C.
Can it replace another 4.3-inch 480 × 272 LCD?
Not by diagonal and resolution alone. Compare the full model and revision, outline, mounting, 40-pin assignment, RGB timing, power sequence, backlight, and any separate touch assembly.
