G104STN01.3 vs G104SAN01.1: Replacement and Compatibility Guide
Compare the legacy 10.4-inch TN module with the AHVA replacement candidate recommended in its manufacturer EOL notice. This guide separates the replacement recommendation from the checks needed to approve it.
Selection answer: G104SAN01.1 is the named replacement candidate, not a verified drop-in substitute. Confirm the preliminary specification revision and validate the candidate in the equipment.

What the EOL Notice Establishes
The supplied AUO Display Plus notice names G104SAN01.1 as the recommended replacement for G104STN01.3. It lists March 13, 2026 as the official notice date and September 13, 2026 as the last-buy order confirmation date. The latter has passed; confirm remaining inventory or previously committed supply. The notice does not give a final shipment date.
TN to AHVA: What Changes in the Equipment?
The reviewed documents change from normally-white TN to normally-black AHVA. The .1 preliminary specification lists higher typical brightness and contrast and wider four-direction viewing angles. Review black level, color appearance, surface reflections and image visibility with the actual controller and cover glass. Higher specified brightness does not guarantee sunlight readability.
Matching Outline Does Not Prove a Drop-in Replacement
Both summary tables list a 227.3 × 177.5 × 9.3 mm typical outline and the same active area. Still compare the full drawings for tolerances, mounting features and connector positions. Verify LVDS pin assignment, mapping, bit depth, timing, LCD and backlight power, dimming and power-on/off sequence.
Power and Preliminary-Data Limits
Do not turn the 3.9 W versus 3.16 W comparison into an equal-condition energy-saving claim: the legacy specification uses an all-black pattern and .1 uses all-white. The .1 and .2 figures both use all-white, but they describe different modules and brightness test settings; qualify actual system power and thermal behavior.
The .1 preliminary optical table lists 10 ms rising, 5 ms falling and 25 ms total, which are inconsistent. Do not calculate a definitive total from these entries. Request clarification or the applicable final specification. Preliminary weights are TBD; do not copy the legacy module’s weight.
Replacement Qualification Checklist
- Record the installed full model, revision and equipment requirements.
- Obtain the applicable controlled datasheets and mechanical drawings.
- Compare outline, tolerances, mounting, connectors and pin assignments.
- Review LVDS mapping, timing, scan direction and bit-depth settings.
- Check separate LCD logic and backlight supplies, dimming and power sequence.
- Validate optical performance and thermal conditions with a sample in the completed assembly.
- Record the approved model and revision in purchasing and engineering records.
Frequently Asked Questions
Does the same 10.4-inch SVGA format guarantee compatibility?
No. Size and resolution do not establish electrical, mechanical or optical compatibility. Compare the full documents and test a sample.
Is G104SAN01.1 a final-specification product in this guide?
The supplied .1 document is Preliminary ver.0.1. Confirm the current controlled revision and availability before design-in.
What should I send for selection support?
Provide the exact installed or target model, quantity, application, destination and delivery schedule. Include controller, cable and mounting requirements. Label photos and drawings can be exchanged separately after the enquiry.
