Using Outdoor Digital Signage in Temperature Extremes

Posted by: Richard Williams | Posted on: March 23rd, 2010 | 0 Comments

Outdoor digital signage is an effective method of advertising and generating brand awareness. The potential audience for outdoor digital signage is always greater than for indoor advertising which is why more and more digital signage is being erected along sidewalks and roads.

Protecting outdoor digital signage is part and parcel of this new outdoor advertising and many outdoor digital signage systems are manufactured waterproof for particular outdoor use. However, the temperature variations in different areas and countries can be extreme and any digital signage tat has to operate in a sub zero temperatures or in areas with extreme heat needs to be protected too.

Methods of cooling DS in hot conditions

Heat is the natural enemy of most electronic devices. All DS screens will produce heat that needs to be carried away. Most digital signage enclosures contain fans to help transfer the heat away from the screen but this cooling is often not adequate enough.

Overheating will disable most DS screens if they are not adequately protected and the problem is exemplified if the screen is situated in a hot climate.

Air conditioning is one solution for locations that suffer extreme heat, however, air conditioning is quite an expensive solution as any outdoor digital signage screen needs to be sealed and the air conditioning system has to be re-gassed at periodic intervals.

Methods of insulating DS in cold conditions

Sub zero temperatures are not normally a problem for electronics unless ice forms from condensation which can permanently damage the screens so preventing ice crystals from forming inside the LCD enclosure is crucial.

Heaters are the best option for digital signage in freezing conditions. Heaters will ensure any condensation trapped inside the digital signage will not freeze it will also keep the optimum operating temperature inside the digital signage enclosure.
