Ruggedization refers to reinforcing devices and equipment to withstand harsh environmental conditions. This includes extreme temperatures, potential vibrations and shocks, moisture, dust and conditions that would harm regular consumer electronics. Rugged displays are display screens and monitors that have been ruggedized to withstand such difficult conditions while maintaining functionality. From military equipment to industrial machines, rugged displays have become essential components that enable many modern applications.
Ruggedization Standards
There are certain standards that specify the exact level of ruggedization for displays. The most common are MIL-STD-810 and IP ratings. The MIL-STD-810 standard defines various environmental conditions like temperature, shock, vibration, altitude, humidity, rain, dust, salt fog etc. Products are tested and certified according to the specific letters/numbers from the MIL-STD-810 standard that they comply with. For example, MIL-STD-810G certification for temperature, shock & vibration.
IP ratings specify a product’s protection against solid objects like dust as well as liquids. An IP67 rating means a product is protected against dust ingress and can withstand temporary water immersion for 30 minutes at a depth of 1 meter. This allows rugged displays to operate reliably even in wet and dirty environments. Complying with established standards assures customers of a product’s ruggedness capabilities.
Uses of Rugged Displays
Military and Aerospace
Rugged Display are indispensable for military vehicles, aircraft, ships and ground units that must function under extreme conditions. From tough submarines to dust storm-prone deserts, displays need to withstand shock, vibration, temperature swings and pressure changes. Leading manufacturers provide MIL-STD certified rugged LCD, LED and touch screen displays up to 46-inches for mission critical use.
Industrial Machinery
Robust industrial machinery relies on rugged displays to provide controls and readouts in harsh factory or outdoor environments. Applications include oil & gas rig equipment, mining machinery, construction vehicles, CNC machines etc. Rugged displays survive high/low temperatures, dust, moisture, electromagnetic interference and mechanical shock inherent to these workplaces.
Public Safety
Police, fire, ambulance and other emergency response vehicles deploy rugged vehicle-mount displays and panels. These allow real-time access to critical information on-the-go despite vibration, temperature extremes, potential water/dust exposure during incidents. Rugged tablets are also used for reporting from field.
Marine Applications
Naval vessels, cargo ships, offshore oil rigs and research vessels installing rugged displays both outdoors and inside machinery rooms. Marine-grade screens withstand salty sea air corrosion, wide temperature ranges from deep ocean to tropical sun exposure.
Transportation Systems
From train control systems to underground metro stations to airports – public transportation networks rely on rugged displays inside equipment rooms and for passenger information. Vibration resistance and wide temperature operation ensure safe 24/7 functionality.
Key Features of Rugged Displays
Wide Temperature Operation
Most rugged displays can withstand temperatures from -20°C to +60°C or even higher up to +71°C. Specialized models are rated for freezing cold -40°C or scorching heat up to +85°C. Pioneering manufacturers have developed patented thermal management to keep screens readable despite extremes.
Shock and Vibration Resistance
Advanced bonding techniques, reinforced casing designs and shock-absorbent mounts enable rugged displays to resist strong vibrations up to 30G/50G while still maintaining clear images. Gorilla Glass or chemically strengthened glass protects against mechanical shocks.
Sealing and Protection
IP ratings of IP65/IP67 provide resistance against high-pressure water jets and dust ingress into screens. Conformal coating on electronic components, sealed ports and gaskets provide further moisture/dust protection for hazardous areas.
Long Lifespan and Durability
Rugged LCD screens are designed to withstand 5-10+ years of continuous use compared to consumer displays lasting 2-3 years. Reinforced materials and optimized components result in rugged reliability.
Wide Viewing Angles
Rugged displays employ advanced LED backlights and IPS/Wide- view panels to provide clear viewing from sides and above/below at inclinations exceeding 80° for usage in vehicles or outdoor environments with direct sunlight.
Touch Screen Flexibility
Projected capacitive touch technology provides multi-touch functionality in gloved fingers or raindrops while continuing to work under vibrations or wide temperature ranges. Technologies like AATT and PCT enable rugged interactive solutions.
Software Integration
Rugged displays run embedded operating systems with integration abilities like Windows, Android or Linux for ease-of-use. Programmable software and drivers customized for industrial applications.
These key features allow rugged displays to thrive where ordinary screens simply cannot function. They power the critical devices keeping our modern world running smoothly. By ensuring readability, durability and 24/7 uptime, rugged displays are indispensable technological enablers across numerous industries.
As technology and machinery continue advancing to harsher environments around the world on land, sea and air, the requirements for displays become more demanding than ever. Ruggedization engineering has risen to this challenge by developing screens optimized for tough conditions. Leading rugged display producers are constantly innovating with new materials like sapphire glass, novel thermal technologies, advanced touch interfaces and customized software. This drives the rugged displays industry forward in supporting special applications across military, oil/gas, maritime, transportation and other vital sectors. Rugged displays pave the way for the digital future even in the most unforgiving surroundings on earth.
