AUO G121EAN01.0 12.1-inch 1280 × 800 LVDS LCD Panel
G121EAN01.0 is a 12.1-inch TFT-LCD module with WXGA resolution, a 16:10 aspect ratio and a single-channel LVDS interface. The reviewed specification lists 500 cd/m² typical luminance, wide viewing angles and an operating temperature range of -30 to +85°C. It includes an LED backlight driver and can be evaluated for industrial HMI, automation and embedded display projects.
Document scope: the supplied Final Specification, Rev. 0.0, dated 19 July 2023, carries G121EAN01.001 in its header and G121EAN01.0 in its model-name field. The values below refer to that document. Confirm the supplied unit's full identification and applicable specification before ordering; this page does not establish that every suffix or revision is interchangeable.

Optical characteristics
Optical values are specified under stable conditions at 25°C. The white-luminance test uses 50 mA per LED line. Typical values are not minimum guarantees.
| Item | Value / condition |
| Center white luminance | 400 cd/m² minimum; 500 cd/m² typical |
| Contrast ratio | 800:1 minimum; 1000:1 typical |
| Five-point luminance uniformity | 75% minimum, calculated as the minimum divided by the maximum luminance of the five test points |
| Response time | 25 ms typical, rising + falling, measured between 10% and 90% levels |
| Viewing angles | 80° minimum / 89° typical in each direction (left, right, up and down), at contrast ratio ≥ 10 |
| White chromaticity | CIE 1931: x = 0.313, y = 0.329, typical |
The optical table lists 72% typical color gamut without explicitly naming the reference gamut. It does not substantiate a 99% sRGB coverage claim or specific Adobe RGB, DCI-P3 or Rec.2020 coverage figures. Request supporting color measurements if those requirements matter to your application.
Electrical and backlight requirements
| Item | Reviewed value |
| Logic supply (VDD) | 3.0 V minimum / 3.3 V typical / 3.6 V maximum |
| LCD input current / power | 500 mA maximum / 1.65 W maximum, at VDD = 3.3 V, 60 Hz, all-white pattern |
| Total module power | 7.45 W typical at white pattern, as listed in the general specification |
| Backlight driver supply | 10 V minimum / 12 V typical / 15 V maximum |
| Backlight input current | 0.5 A typical at 12 V and 100% PWM duty |
| Backlight power | 5.8 W typical at 12 V and 100% PWM duty |
| PWM dimming | 200 Hz to 20 kHz; 1-100% duty, with non-linear behavior noted at 1-5% |
| Signal connector | 30 pins; Starconn 093G30-00001A-M4 in the reviewed specification |
| Frame rate | 60 Hz typical in the timing table |
The connector carries LVDS signals, logic power, backlight power and control signals. Do not assume that another 30-pin cable has the same wiring. Verify the complete pin assignment, SEL68 input setting and power-on/off sequence before connection. Turn off power before inserting or removing the cable.
The reviewed document's signal description and timing table give different clock-frequency values. Obtain the applicable timing confirmation before configuring a controller; the brief specifications on this page are not a wiring or controller-programming guide.
Backlight life and operating conditions
The backlight table lists an estimated minimum life of 70,000 hours at IF = 43.1 mA and ambient temperature 25°C. Life is defined as the time until brightness falls to 50% of its initial value. Higher current, temperature or humidity can reduce operating life. This is a conditional specification estimate, not a whole-system lifetime or warranty commitment.
The lifetime condition differs from the 50 mA per LED line used for the luminance measurement. Do not combine the two conditions into a promise of 500 cd/m² for 70,000 hours. Follow the manufacturer's environmental limits, including the non-condensation requirement, and validate the installed module within the actual enclosure.
Selection and replacement checks
- Confirm the full label identification, document revision and required quantity.
- Compare the outline, typical thickness, mounting details and connector location with the enclosure drawing.
- Verify LVDS pin mapping, bit-depth selection, timing, cable wiring and separate logic/backlight power requirements.
- Evaluate brightness, viewing angles, thermal behavior and image retention under the intended operating conditions.
- Select and validate any touch panel, bonding, controller board or cable assembly separately.
A matching 12.1-inch size and 1280 × 800 resolution do not prove interchangeability. The specification applies in landscape orientation; do not assume portrait operation or a hardware reverse-scan feature without confirmation. Module specifications do not replace complete-system environmental, EMC or safety validation.
Packing and procurement
The reviewed packing specification lists up to 20 modules per carton, a maximum carton weight of 15.5 kg and external carton dimensions of 450 × 375 × 320 mm. Confirm actual packing before arranging freight. Current stock, lifecycle status, lead time and lot details must be checked for the requested order.
Questions before ordering
Which documents should I request?
Ask for the specification and mechanical drawing applicable to the exact supplied unit. If required, also request available RoHS declarations, traceability information and current PCN/EOL documentation. The supplied specification identifies the product as RoHS compliant; it is not a substitute for order-specific compliance evidence.
Can it replace an existing panel?
Send the current panel's full label, specification and cable information for comparison. Mechanical fit, power, timing and pinout must all be checked before approval.
What should an RFQ include?
Provide the full model code, quantity, application, delivery country, required date and any touch, cable or controller requirements.
