Enhanced outdoor performance for LOGIC INSTRUMENTs military notebook series

July 13, 2012 - PRLog -- Dusty or rainy environment – These rugedd laptops can stand it even with open interface caps

Military missions mostly don’t taking place in surrounding where other people spend their holidays. These are rough outdoor environments. This demands the full effort of humans and equipment, where the IT hardware is no exception. The equipment must be prepared for all occasions: High and low temperatures, dust, water, vibration,…  The TETRAnote EX-series had previously been one of the leading brands in this field – from now on, the three military notebooks are even more rugged.

Since late June, LOGIC INSTRUMENT received the IP65 certification for the TETRAnote EX15, which confirms its dust-and water proofness, to guarantee the usage even under very difficult outdoor conditions. Likewise, LOGIC INSTRUMENT made the IPx5 certification for the entire EX-series - the special thing about it: the certification is valid even with open interface caps, which makes the series one of the safest in the outdoor area.


Outdoor screen readability goes to the next dimension

Optical bonding refers to a protective glass that is glued in front of the display to enhance its readability where installed in high humidity outdoor environments. When a normal display is used in an outdoor environment, there are some factors that affect its readability. The most common one is condensation, which forms on the inner surface of display's vandal shield. Another factor is the reflection of sunlight, which causes a mirror-image on the display. Using optical bonding can solve both phenomenons.

The main goal of optical bonding is to improve the display performance under outdoor environments. This method eliminates the air gap between the cover glass and the display. The real problem for display readability in outdoor environments is not the display's brightness but its contrast. Contrast means the ratio of the white level to the black level; in other words, the contrast ratio of display means the difference of light intensity between the brightness white pixel and the darkest black pixel. The main purpose of optical bonding is to increase the display's contrast ratio by reducing the amount of reflected ambient light.   

Benefits of LOGIC INSTRUMENTs bonded displays:
•   Increased ruggedness: Bonding a sheet of glass on top of the display increases the ruggedness of the display.
•   Improved durability: A bonded display is better able to resist scratches, fluids, stains and dirt.
•   Condensation: The elimination of an air gap between the cover glass and the display means that moisture cannot penetrate and cause fogging on display’s surface.
•   EMI filtering: The technology allows to add addition EMI filters
