Rugged Displays: Unyielding Solutions for Harsh Environmental Conditions
Sturdy displays are designed to operate reliably in harsh environmental conditions such as extreme temperatures, vibration, humidity, electromagnetic interference, and other factors. They incorporate specialized features that make them durable enough to withstand the challenging conditions found in military, industrial, marine and outdoor applications.
Design Considerations for Rugged Displays
Sturdy displays are built with durability in mind from the ground up. Their constructions differ substantially from commercial-grade displays intended for indoor use. Key aspects of their design include Rugged Display casing and enclosure materials, seamless touch screens, anti-glare treatments, wider operating temperature ranges and improved dust/water resistance.
The enclosure is a crucial element in achieving ruggedness. Military-grade displays use cast aluminum, magnesium or composite housings that can withstand high impacts from drops, vibrations, pressure changes and other physical stresses. Commercial units often use plastic which is lighter but more vulnerable to damage. The enclosure seals keep out water, dust and chemicals.
Touchscreen Technology
Sturdy displays integrate touchscreen interfaces suitable forgloved fingers or stylus use. Resistive touchscreens provide rugged reliability but are less precise than other technologies. Projected capacitive touch offers the best visual experience and responsiveness along with durability to withstand rough usage and protect against humidity, dirt and debris. Forceshield touch overlays from companies like Synaptics deliver cutting-edge projected capacitive performance rated to IK09 impact and NEMA IP67 sealing standards.
