What are the selection factors for industrial LCD screens?
Date:2025-09-26
The selection of industrial LCD screens requires comprehensive consideration of multiple dimensions such as environment, performance, interfaces, lifespan, and cost. The following is a selection guide for industrial LCD screens based on the latest industry data in 2025, helping you avoid common misconceptions and accurately match project requirements:
I. Core elements of selection
Dimension | Selection suggestions |
Brightness | Indoor: 250-400 nits; Semi outdoor: ≥ 700nit; Outdoor: ≥ 1000nit, high brightness LED backlit screen is preferred for strong light visibility |
Resolution | Choose based on the complexity of the displayed content: 800 × 480 for simple UI; Charts/data often use 1280 × 800 or 1920 × 1080 |
Size | Commonly 4.3 "~55", choose according to installation space and visible distance. Select 12.1 "for portable devices and 15.6" for multi window analysis |
perspective | Wide viewing angle: 89/89/89/89, ensuring clear viewing of screen content from different directions |
Operating Temperature | Industrial grade should support -30 ℃~+80 ℃ to ensure stable operation in extreme environments |
Protection level | Choose IP65 or above for dusty/water environments; Food processing or outdoor recommended IP67 |
Interface type | LVDS: Strong anti-interference, suitable for industry; EDP: High bandwidth, suitable for high-end controllers; HDMI/VGA is suitable for short distance commercial use |
Service life | Industrial grade LCD lifespan ≥ 50000 hours, LED backlight better than CCFL |
Anti-interference | EMI/ESD testing is required, and additional features include shielding design, magnetic rings, anti-static coatings, etc |
I. Recommended Typical Application Scenarios
Application scenarios | Recommended Configuration |
Factory Automation | Resistive touch+IP65+Wide temperature range+LVDS interface |
Medical equipment | Capacitive touch+antibacterial screen+high resolution+eDP interface |
Spectrum analyzer/testing equipment | 12.1 "or 15.6"+high brightness+LVDS/eDP dual interfaces+anti-interference design |
In-vehicle system | Capacitive touch+anti vibration+wide temperature range+high reliability |
Food processing | Resistive touch+IP67+Chemical resistant coating |
III. Common selection misconceptions (to avoid)
1. Neglecting interface compatibility
If VGA is susceptible to interference in industrial environments, it is recommended to prioritize LVDS or eDP.
2. Only look at the price, not the certification
Industrial applications require certification for vibration, waterproof, explosion-proof, EMC, etc., such as IEC, ATEX, etc.
3. Ignoring long-term usage costs
High brightness screens have high power consumption, with 400nit saving 37% annually compared to 700nit. Large scale deployment requires evaluation of energy consumption and carbon emissions.
IV. Popular Model Reference (2025)
Model | Size | Resolution | Brightness | Interface | Feature |
INNOLUX 7-inch LCD Screen | 7" | 800×480 | About 450 nits | RGB TTL | Compact and high brightness, preferred for embedded systems |
12.1-inch industrial screen | 12.1" | 1280×800 | high brightness | LVDS | Strong anti-interference ability, suitable for portable devices |
15.6-inch industrial screen | 15.6" | 1920×1080 | high brightness | LVDS+eDP | Multi window display, suitable for high-end instruments |
V.Summary and Suggestions
Prioritize matching environmental requirements: temperature, humidity, dust, electromagnetic interference, etc.
Redefine performance parameters: brightness, resolution, touch mode.
Finally evaluate the interface and compatibility: ensure seamless integration with the main control system.
Choose certified and serviced suppliers, such as Hangzhou Xuhong, who provide technical support and customized services.
