Innolux AT070TN94 Replacement and Compatibility Guide
How can we help with AT070TN94 replacement?
Include the exact model, quantity, destination and required date for a useful reply.
This guide helps engineering and purchasing teams screen alternatives for the exact Innolux AT070TN94. It does not claim a universal drop-in substitute. The host, cable, enclosure, optical stack and environmental qualification must be checked together.
Data source and specification version
Updated:
- INNOLUX DISPLAY CORPORATION, AT070TN94 LCD Module Specification, Final Specification, Version 01, dated 2023-11-18.
- Printed pages 1, 2–4, 5–8, 14–18 and 20–21: general specifications, pin assignment, electrical and absolute-maximum ratings, optical conditions, reliability, mechanical drawing and packing.
Replacement approval: Match the exact module revision to the host, cable and mechanical drawing, then validate samples in the equipment. The specification does not establish current production status, stock or automotive qualification.
AT070TN94 reference specifications
| Panel size and resolution | 7.0 inch, 800 × 480 pixels (800 × 3 RGB × 480 dots); printed p. 1. |
|---|---|
| Brightness | 320 cd/m² minimum, 400 cd/m² typical at Ta = 25°C, DVDD = 3.3 V and LED current = 180 mA; printed pp. 14–16. |
| Interface | 18/24-bit parallel digital RGB; 50-pin, 0.5 mm pitch. Recommended mating connector: Hirose FH12A-50S-0.5SH. Match the full RGB/control pin map, voltage and timing; printed pp. 2–4. |
| Temperature ratings | TOP and TST are both -30°C to 85°C in the absolute-maximum table, not an unconditional 85°C ambient operating guarantee; printed p. 5. The high-temperature operating test uses panel-surface temperature Ts = 85°C; printed p. 18. |
| Contrast and viewing | Contrast: 400:1 minimum, 500:1 typical. Viewing angles L/R/U/D: 70°/70°/50°/70° typical at CR ≥ 10, under the stated optical test conditions; printed pp. 14–17. |
| Outline | 164.9 × 100.0 × 5.7 mm nominal; depth tolerance ±0.3 mm. Active area: 154.08 × 85.92 mm. Check all drawing tolerances and connector orientation; printed pp. 1 and 20. |
| Backlight | LED backlight: 9.3 V typical and 180 mA typical. Minimum life is 20,000 hours to 50% of initial brightness at Ta = 25°C and IL = 180 mA; lifetime decreases above 180 mA. Confirm the required LED drive and pin assignment; printed pp. 2 and 7–8. |
| Availability and lifecycle | The dated specification does not establish current production status, stock or lead time. Confirm the exact revision and current supply before purchase. |
Why a 7-inch WVGA panel is not automatically compatible
AT070TN94 candidates can differ in outline, active area, mounting tabs, FPC position, pin assignment, signal mapping, voltage, timing, backlight driver and viewing direction. A matching diagonal and resolution are only the start of the review.
Replacement qualification workflow
- Record the complete model and revision from the rear label.
- Compare the latest outline and active-area drawings.
- Compare every interface pin, voltage, timing and cable orientation.
- Verify backlight voltage, current, dimming and driver topology.
- Confirm temperature, brightness, touch stack and enclosure constraints.
- Test samples in the production controller and enclosure before BOM approval.
Applications and selection risks
Select the application against the documented electrical, optical and thermal conditions. TOP/TST limits and reliability tests do not certify transportation or automotive use, or guarantee full optical performance at an 85°C ambient temperature. Validate sunlight readability, vibration, thermal design, humidity and EMC in the complete system; printed pp. 5 and 14–18.
Purchasing information to include
Send the original label photo, drawing or datasheet, controller and cable details, required quantity, destination, target date, application environment and whether cable or mechanical adaptation is acceptable.
Frequently asked questions
Can any 7-inch 800 × 480 LCD replace AT070TN94?
No. Mechanics, connector, pinout, voltage, timing, backlight and optical requirements can differ.
Does a 50-pin FPC prove compatibility?
No. The full pin map, signal standard, voltage, pitch, position and cable orientation must match.
Do the -30°C to 85°C ratings guarantee operation at 85°C ambient?
No. TOP/TST appear in the absolute-maximum table on printed p. 5. The high-temperature operating test on printed p. 18 specifies panel-surface temperature Ts = 85°C. Validate the actual ambient, panel temperature and optical requirements in the equipment.
What is the safest purchasing process?
Compare documents first, inspect exact-revision samples, and validate them in the actual equipment.
