Outdoor Digital Signage
There are lots of challenges when implementing outdoor digital signage but despite this more and more digital displays are being erected out to take advantage of their higher audience numbers these outside digital advertising displays can generate. While the most obvious challenge for taking a industrial grade LCD screen outside is shielding it from the weather, and in particular rain, the problems associated with the sunlight can be just 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 warmth (you must know what that is like when you try and see the TV at home throughout the summer months where quite often you’re forced to close the curtain to see the display clearly) but even if there is no warmth in bright sunlight the display will appear dim and difficult to see. But there are methods to ensure the display is as easy as possible when taken outdoors:
Assuming you’ve the brightest type of display possible will go along way to ensuring 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 screen should be 800 nits but LCD with 1000+ nits can be found and must be considered when seeking to get into outdoor digital signage. It should also be mentioned that in general industrial displays have higher nit values and therefore are better suited to outdoor signage displays.
Preventing glare is accomplished in many of ways. Regrettably, no matter which way you select that there most likely will be some drop-off in brightness. Direct sunlight can cause more problems than simply glare too. Screen burn can grow if sunlight is continually on it so either the outside digital display should be turned off from sunlight another solution to protect against this display burn should be looked at such as cooling the display itself.
Bespoke Outdoor Content
A great deal of content that works well in indoor locations doesn’t respond well to be taken outdoors. Use colors and designs that are more prominent in outdoor locations. There is frequently a great deal of trial and error involved in this but check what works and what doesn’t and you should soon develop a teaser for designing content that is acceptable for outdoor digital signage.
