When we talk about industrial touch displays for outdoor use, the first thing we need to focus on is their weather resistance. Extreme low and high temperatures, intense sunlight, humidity, dust or UV radiation are all challenges that traditional displays face that can make or break their lifespan, so industrial displays must be designed and manufactured to withstand these harsh conditions. So what factors should be considered when choosing a display for use outdoors, outside of a building?
Resistant to Extreme Weather Conditions
LCD-TFT displays for outdoor applications require a number of factors to be considered to ensure proper operation in a variety of extreme weather conditions. One key parameter is the wide operating temperature range, with many displays specified to operate from -20 to 70°C or even -30 to 85°C. In addition, any electronics intended for outdoor use must be properly protected from potential contaminants such as dust, dirt and water. This can be achieved by placing the device in a properly sealed enclosure.
Superior Optical Performance
Optical parameters, which are critical to image quality. Industrial displays for outdoor applications must have excellent performance such as high contrast, brightness and wide viewing angles. Why is it so important? Because these parameters ensure that the display ensures image readability even under strong sunlight. In addition to choosing a display with high contrast, brightness and wide viewing angles, the user experience can be improved by reducing glare through special treatments on the cover surface, such as anti-reflective (AR) or anti-glare (AG) coatings. Different combinations of anti-reflective layers can be used to reduce reflectivity to as low as 2%.
Easy to operate and maintain
Operation and maintenance of industrial displays is an important issue. They should be designed to be simple, intuitive, easy to use and easy to maintain. This makes it possible to minimise maintenance costs. This is also essential for optimising production processes and maintaining business continuity.
When operating a display, the most reliable and versatile way to interact with the screen today is to use a capacitive touch sensor. wiwotouch has been working on touch screens for many years, and we support customised waterproof, glove-touch, multi-touch touch screens.
Safety First
User safety is a key aspect of outdoor touch screen design, it must be able to resist all types of damage and vandalism.WIWOTOUCH each touch sensor module is protected by protective glass, which prevents mechanical damage. Some customers require a glass cover with a thickness of 6mm in order to ensure adequate protection of the module - for this type of solution, a certain degree of resistance to mechanical loads can be achieved according to the IK10 level PN-EN 62262 guideline.
For devices operated by thousands of people, such as self-check-in points in airports or self-service devices in hospitals, the use of antimicrobial (AM) coatings is recommended to reduce the likelihood of microbial colonisation of screen surfaces applied by the user. Its effectiveness has been determined to be at least 99.9%.
