| IAVDD | 5 mA | 20 mA | 50 mA | AVDD=10.4 V |
Current conditions: printed p.7. The module uses multiple supply rails; 3.3 V describes DVDD, not a complete single-supply module specification. Apply DVDD and VGL before VGH. Follow the complete power-on/off timing diagrams on pp.9–10.
LED backlight
| Parameter | Minimum | Typical | Maximum | Source / definition |
|---|---|---|---|---|
| Backlight voltage | 8.4 V | 9.3 V | 10.2 V | pp.7–8; at 25°C, 180 mA |
| Backlight current | 170 mA | 180 mA | 200 mA | p.7; whole backlight |
| LED life | 20,000 h | Not specified | Not specified | pp.7–8; minimum to 50% initial luminance at 25°C, 180 mA |
LED power is applied through pins 1–4. The 20,000-hour figure is a defined luminance-life value, not a warranty. Lifetime can decrease above 180 mA. Confirm the backlight-driver design for the actual assembly.
Timing reference
| Item | Specified reference | Source |
|---|---|---|
| Typical DCLK frequency | 33.3 MHz | p.12 |
| Frame rate | 60 ±5 Hz | p.12 |
| Horizontal active / typical total | 800 / 1056 DCLK | p.12 |
| Vertical active / typical total | 480 / 525 lines | p.12 |
Use the complete AC and input-timing requirements on pp.11–13. The document’s DCLK cycle-time and frequency endpoint tables do not fully correspond; confirm endpoint operating combinations with the manufacturer rather than deriving a new guaranteed range.
Absolute ratings and environmental qualification
The following limits are listed in the specification’s Absolute Maximum Ratings table (p.5). They are not substitutes for the recommended electrical settings above.
| Item | Minimum | Maximum |
|---|---|---|
| DVDD | −0.3 V | 5.0 V |
| AVDD | 6.5 V | 13.5 V |
| VGH | −0.3 V | 40.0 V |
| VGL | −20.0 V | 0.3 V |
| VGH−VGL | Not specified | 40.0 V |
| TOP, operation temperature | −30°C | 85°C |
| TST, storage temperature | −30°C | 85°C |
| LED forward current, each LED | Not specified | 25 mA |
| LED reverse voltage, each LED | Not specified | 1.2 V |
Reliability tests on p.18 include high-temperature operation at panel-surface temperature Ts=85°C for 240 hours, low-temperature operation at ambient Ta=−30°C for 240 hours, and operation at +60°C/90%RH for 240 hours. The 85°C condition is not an unconditional guarantee for ambient temperature or all optical performance in finished equipment.
The documented vibration test is 1.5G, 10–55–10 Hz, 2 hours per X/Y/Z direction; mechanical shock is 100G/6 ms. These component test conditions do not establish automotive certification, finished-system qualification or warranty coverage.
Packaging reference
| Item | Specification | Source |
|---|---|---|
| Quantity | 50 modules/carton, 2 rows × 25 | p.21 |
| Carton dimensions | 525 × 362 × 250 mm | p.21 |

Packaging is the reference configuration in this document. Confirm actual shipment packing, quantity and current commercial terms with the quotation.
Compatibility review and quotation
Send the complete panel label and revision, controller/cable information, required quantity, destination and application conditions. Compare the parallel RGB pin map, all power rails, backlight drive, timing and mechanical drawing before approving a substitute. Current production and stock status are confirmed separately from this 2023 specification.

Frequently asked questions
What interface does AT070TN94 use?
The Ver.01 pin assignment identifies parallel digital RGB with R0-R7, G0-G7 and B0-B7 data, plus DCLK, HS, VS and DE. For 18-bit input, ground the two low bits of each color channel. The recommended connector is Hirose FH12A-50S-0.5SH.
What are the typical viewing angles?
At contrast ratio CR ≥10, typical left/right/up/down viewing angles are 70°/70°/50°/70°. The respective minimum values are 60°/60°/40°/60°, under the optical test conditions in the specification.
What does the 20,000-hour LED life figure mean?
It is the specified minimum time until luminance falls to 50% of its original value at ambient 25°C and backlight current 180 mA. It is not a product warranty; operating above 180 mA can reduce lifetime.
Does the specification confirm current supply or replacement compatibility?
Current production, stock, price and order terms must be confirmed separately. A replacement requires the complete model/revision, RGB pin map, power rails, backlight drive, timing and mechanical fit to be checked in the actual equipment.
