LCD Television in Outdoor Digital Signage

Technology advancements in the flat panel television industry now dictate that we use LCD televisions in outdoor digital signage solutions, due to their cost effective nature.

Gone are the days that the CRT (Cathode Ray Tube) TV sets are in-stores to buy, due to the falling cost of the new flat panels coupled with the comparable smaller depths of the actual TV, making plasma and LCD TV's the perfect choice for indoor as well as outdoor digital signage.

There are two concerns when putting new flat panels outdoors, these are:

The screen must be readable even in direct sunlight otherwise customers will not see the ads on the display. Secondly the TV must offer some sort of waterproofing - protecting LCDs from the weather elements. Otherwise the display will just corrode in the damp environment.

Another sometimes overlooked issue is how to mount the LCD enclosure as the actual flat panel is mounted on an internal TV mounting frame, normally these enclosures come with some sort of bracket on the rear of the enclosure, but note there are some manufacturers of LCD enclosures that drill through the back of the enclosure to fit the bracket, this reduces the waterproofing of the unit.

One manufacturer in particular supplies a unique bracket that is theft resistant, this bolts to the rear of the enclosure and the fastenings are fully sealed so now fluid can enter the enclosure when in suit. The bolts used are special anti-theft bolts, so once in place you can only remove them with a grinder.
