Outdoor Digital Signage
There are plenty of challenges when applying outside digital signage however despite this more and more digital displays are being built outside to make the most of the higher audience numbers these outdoor digital advertising displays can create. While the most obvious obstacle for taking a commercial grade LCD screen outside is shielding it from the weather, and in particular rainfall, the problems associated with the sunlight can be equally as difficult to overcome.

The issue with the sunlight and outdoor digital signage is that direct sunlight will frequently create the screen unreadable. Not only can sunlight cause glare (you must know what that’s like when you try and watch the TV at home throughout the summertime where very often you are forced to shut the curtain to see the screen obviously ) but even if there’s absolutely no glare in bright sunlight the screen will look dim and difficult to read. But there are methods to ensure the screen is as readable as possible when taken outdoors:
Ensuring you have the brightest kind of screen potential will go along way to making sure the screen is readable. The brightness of LCD screens is measured in nits (aka candela per square metre). The minimum screen brightness for any outdoor LCD screen should be 800 nits however LCD using 1000+ nits are available and must be considered when seeking to get into external electronic signage. It should also be noted that in general commercial displays have higher nit values and therefore are better suited for outdoor signage screens.
Preventing glare is done in a number of ways. Optical bondng, anti-reflective glass and tinting are only some options. Regrettably, whichever way you go on this there probably will be some drop-off in brightness. Direct sunlight can cause more problems than just glare also. Screen burn can grow whether the sun is constantly on it so either the outdoor digital screen should be turned away from the sun or some other remedy to protect against this screen burn should be considered like warming the screen itself.
Bespoke Outdoor Content
A great deal of content which works well in indoor places does not respond well to be taken outdoors. Use colours and designs which are more prominent in outdoor places. There is frequently a lot of trial and error involved with this but check what works and what does not and you should soon develop a flare for designing material that’s acceptable for outdoor digital signage.
