SELECTING RUGGED INDUSTRIAL DISPLAYS THAT LAST

Rugged display performance is shaped by optical, mechanical, and environmental factors. This checklist covers the variables that most influence readability and reliability to help you make an information display selection for your application. 

Readability and Optics 

A display’s readability starts with how bright it is and how it manages reflections. Brightness is measured in nits, a unit describing how much light the screen emits. Coatings and touch screen bonding choices can further determine how efficiently that light translates into on-screen visibility.

Brightness (Nits): 

• The more well-lit the environment is, the greater the nits will need to be to compensate for the glare.
• As a rule, ~300 nits suffice for indoor use; ~1,000+ nits for outdoor spaces
• If the display will be in direct sunlight, it may require even greater brightness, such as 1500+ nits.
• Target the lowest nit level that’s readable in your situation, as higher brightness displays typically come with a higher price point.

Glass Coatings: 

• Anti-glare coatings diffuse reflections but softens contrast. 
• Anti-reflective coatings reduce mirror-like reflections while maintaining edge sharpness. 

Touch Screen Bonding: 

• If the display has a touch screen, the bonding method has a great impact on readability. 
• If a touch screen is used, the brightness of the display will need to be increased to compensate for the fact that the touch screen itself will block some light. 
• Optical bonding eliminates the air gap between the cover lens and LCD, reducing reflections and improving contrast at higher cost.  
• Tape bonding is lower cost but may reduce some of the readability due to the air gap created. It will also require a higher brightness display. 

Touch Interface 

Choose touch technology based on glove use and potential exposure to contaminants. 

• Projected Capacitive (PCAP): Best for light gloves and low moisture; offers high clarity and responsiveness.  
• Resistive Touch: Best for thick gloves, oil, or persistent spray; avoids missed touches and false triggers. 

Protection 

Decide on ingress protection (IP) alongside mounting approach. IP ratings define how well an enclosure resists dust and moisture intrusion. 
 
The most common IP ratings for rugged use are: 

• IP65: Rain and low-pressure jets 
• IP67/68: Temporary immersion 
• IP69K: Hot, high-pressure washdowns 

If the rear of the assembly sits inside a sealed cabinet, you can select a display with an IP65 or IP67 front bezel. Installing this into a cabinet with proper gasketing can cut costs without sacrificing protection. Consider bezel thickness, mounting, and thermal paths to achieve full mechanical integrity. 

Materials and Connectors 

• Materials 
  • For high-traffic or public spaces, specify hardened or vandal-resistant glass. 
  • Verify chemical resistance to the cleaning solutions that will be used.

• Connectors 
  • Use locking, waterproof options in high-vibration or tamper-prone settings. 
  • Add strain relief and cable routing early in design.
