Factors to Consider Before Buying
Resolution and Display Quality
When picking a screen for industrial use, resolution matters a lot. It helps with clear reading and sharp pictures. The AUO G121SN01 V403 has a resolution of 800 x 600 pixels and a brightness level of 500 cd/m², ensuring clear and vibrant visuals suitable for both indoor and outdoor environments.
Brightness and Contrast Ratio
Good brightness is key to seeing clearly in different lights. The G121SN01 has a brightness of 500 cd/m². This makes it work well even in sunny places. Plus, a contrast ratio of 700:1 gives images nice depth and detail.
Viewing Angles
This screen uses TN (Twisted Nematic) tech. It usually has tighter viewing angles than IPS screens. But, it responds faster. This trade-off often works fine for fixed industrial setups.
Response Time
Exact response time isn’t given here. Still, TN screens like the G121SN01 are often quick. This helps in tasks needing fast updates, like automation controls or monitoring tools.
Power Consumption
Saving power is super important in some places. In terms of low power consumption and long service life, its LED backlight has a lifespan of up to 50,000 hours, with an input of 10.8 – 12.6V at 330mA. The typical power consumption of the whole unit is 4.62W.
Operating Temperature Range
Industrial spots can get very hot or cold. Operating Temperature from -30~85℃ means this screen works fine in freezing storage or hot factory areas.
Durability and Reliability
Strength is important to cut down on repair costs. The product has a compact and vibration-resistant structure, fixed with six-way M3.4 surface fixing screws. Moreover, its frame is of high strength and weighs 750g. So, it can handle shakes and bumps in moving or shaky machines.

Compatibility with Industrial Equipment
The LVDS interface makes it easy to connect with most industrial setups. Also, Miqidisplay can tweak things like cables. This helps match the screen to your exact needs.
Pricing and Availability Considerations
