Benefits of Optical Bonding For Outdoor Monitors
Optical bonding is a method in which it provides enhanced visibility and durability to LCD monitors. Between the LCD module and the cover glass or touch panel of a monitor is a tiny gap of air. In optical bonding, a layer of resin is applied to fill the gap, uniting the two together and filling the air gap. With optical bonding, it decreases parallax issues, eliminating the gap that creates the illusion that pixels shift position depending on the line of sight. Optical bonding also increases the display’s range of viewing angles and delivers more accurate touch alignment in touch-based interactive systems.

What is MIL-STD Rating?
The U.S. Military Standard (MIL-STD) gives a guideline for devices that are said to be “rugged” or “ruggedized”. It was introduced to provide a series of tests to simulate how the material would hold up to environmental stress during an operational lifetime. The MIL-STD standards detail 28 different testing methods that cover everything from temperature to fungal infestation to gunfire. The eight tests used to determine if a computing device is rugged include high temperature, low temperature, rain, humidity, sand and dust, immersion, vibration, and shock.
