Digital signs have become a vital resource for many local businesses. Digital signage from DigitalHDA is also the ideal tool to relay public safety notifications as well as real time updates for weather and road conditions. Many of our customers’ signs are located to target the greatest audience, which is often in unconditioned areas or areas that fluctuate wildly in temperatures such as high traffic hallways and entrances, against outside windows or even placed outside in specialized cabinets.
If you’ve invested in a digital sign you’re obviously concerned about maintaining your display even in case weather emergencies would put your sign in what many would consider unusual conditions for electronics or how the weather may affect it’s operation.
The first thing you don’t have to worry about is turning your sign off. It’s actually better to keep your sign running as the internal heat generation will keep the internal circuit boards free from condensation provided power is not disrupted. Outside cabinets are specifically designed and sealed to keep your sign safe from excessive condensation and may even include auxiliary heaters to keep the sign running in optimal condition. If the power does get disrupted, the best thing to do is wait to turn it back on until the room containing the sign is sufficiently heated (at least to 40 degrees F) for about 12 hours. You may also have to contact your display maintainer to make sure no dangerous conditions or corrosion have developed during extreme weather events.
If you are installing your sign in such a location, you should have your installer evaluate whether the set you are planning on purchasing is appropriate for the conditions. Some commercial displays have options for the manufacturer to seal the display from ingress of dust and water (such as occasional or continuous gusts of rain or snow). Additionally, your player should also be able to operate in these conditions, standalone players often do not generate sufficient heat to self-sustain them and thus they must have additional protection, be placed in different locations or be integrated into the display.
What you may notice in certain cases is when the temperature drops low enough that older or cheaper displays appear to “ghost” during moving scenes such as video ads. As LCD crystals inside the display cool down, they react slower to the changes necessary for the display to animate and sections may even freeze completely. Modern LED-based commercial displays no longer contain these crystals and would not be affected by the limitations of LCD technology.
If you would like to evaluate your current digital signage solution or are planning a brand new installation, contact DigitalHDA, our technicians and manufacturers have the resources and experience to acquire the correct technology and install your sign wherever it makes the biggest impact, without worrying about the environment.
