Outdoor Digital Signage
There are plenty of challenges when implementing outdoor digital signage but despite this more and more digital screens are being erected outside to make the most of the higher audience numbers these outside digital advertising screens can generate. While the most obvious challenge for taking a commercial grade LCD display outdoors is shielding it from the weather, and in particular rain, the problems associated with the sunlight can be equally as difficult to overcome.

The problem with the sunlight and outdoor digital signage is the direct sunlight will often make the screen unreadable. Not only can sunlight cause warmth (you should know what that’s like when you try and watch the TV at home during the summertime where quite often you’re forced to shut the curtain to watch the display obviously ) but even if there is no warmth in bright sunlight the display will appear dim and difficult to read. However there are methods to ensure the display is as readable as possible when taken outdoors:
Ensuring you have the cleverest kind of display potential will go along way to making sure that the display is readable. The brightness of LCD displays is measured in nits (aka candela per square metre). The minimum display brightness for any outside LCD display should be 800 nits but LCD with 1000+ nits can be found and must be considered when looking to get into external electronic signage. It should also be noted that in general commercial screens have higher nit values and therefore are better suited to outdoor signage displays.
Anti-glare technology
Preventing glare is done in many of ways. Regrettably, whichever way you go on that there probably will be some drop-off in brightness. Direct sunlight can cause more problems than just glare too. Display burn can grow whether sunlight is continually on it so either the outside digital display ought to be turned off from sunlight or some other solution to protect against this display burn ought to be looked at like cooling the display itself.
A lot of content which works well in indoor locations does not respond well to be taken outdoors. Use colours and designs which are more prominent in outdoor locations. There’s often a lot of trial and error involved in this but assess what works and what does not and you should soon develop a teaser for designing material that’s suitable for outdoor digital signage.
