Visual Andon Systems: When to use Industrial LCD or LED Displays

Posted by Jason Sluyter on Oct 7, 2015 4:49:00 PM

There is confusion in the marketplace when considering which technology to deploy for your Visual Andon System. There are two prominent technologies that are widely in use in the Manufacturing Environment, namely, Industrial LED Backlit LCD Displays and Industrial Full Matrix LED Displays. Recent advances in the consumer market are driving a trend towards LCD displays, but before making this capital investment, let’s explore the benefits of both technologies. 

Note: Moving forward when I say LCD Displays, I am referring to Industrial LED Backlit LCD Displays. Also when referring to LED Displays, I mean Industrial Full Matrix LED Displays. 

Display Manufacturing Environment is Key

Your manufacturing environment is a key factor in determining which technology to choose. The following list describes a few areas to pay attention to when considering which technology to go with. 


  • Display Temperature: LED Displays are typically rated for -20°Cto 65°C whereas LCD Displays are only rated for 0°C to 40°C
  • Cleanliness of Display: Both can be protected from harsh environments with proper enclosures (Nema 12, 4 & 4X or IP65, 66 & 67), but enclosing the displays affects the internal operating temperature.
  • Ambient Lighting: LED Displays typically have better contrast compared to LCD Displays making the LED Displays more visible in brighter conditions. 


Pay Attention to Durability and Life Expectancy

The two big indicators of this are mean time between failures and warranty. 
  • Mean Time Between Failures (MTBF): LED Displays are often rated for 100K hours whereas LCD Displays are rated for 60K hours.
  • Display Warranty: Typically the warranty for LED Displays is 5 years comparatively a LCD Display warranty is 3 years

Note the Content Display Abilities

  • Color Display Options: Both technologies support a full range of color options
  • Alphanumeric vs Pictures & Graphs: LCD Displays support all images due to their high-resolution nature i.e. 1080p, whereas LED Displays are ideal for alphanumeric data.
  • Display Viewing Distance: Largely depends on the overall size of the displays and font sizes used. Most LCD Displays are viewed better within a 100Ft. LED Displays are commonly used when the viewing distance is greater than 100Ft
  • Modularity/Scalability of Display: LED Displays are custom built to fit the requirements of the application based on overall matrix (pixels tall by pixels wide), whereas the size of an LCD Display follows the trends of the consumer LCD/TV market (currently 55” is common). 

Determine the Cost of Ownership

  • Display Purchase Price: Capital expense per LCD Display is cheaper compared to an LED Display until you exceed the consumer LCD/TV market size.
  • Installation/Networking Cost of Display: The cost of installation is similar per unit regardless of a LCD or LED Display.
  • Maintenance Cost/Mean Time To Repair: An LCD Display is one module and will have to be replaced completely if a failure occurs. This may require shipping it back to the factory for replacement. LED Displays are more modular and individual components can be replaced in the field without much downtime. 

Hopefully the information provided regarding Visual Andon Technology has helped answer some of your questions regarding Visual Andon Displays and the systems they support.
