Since LCD screens began dominating the home entertainment sector, the large flat panel TVs have got bigger and bigger. IT is now not uncommon for large 50” plus screens to be used in people’s front rooms, and when LCDs are taken out of the home and used as digital signage then even larger screen sizes are used.
Increasingly, TV manufacturers are producing larger and larger sizes of LCD TV, and with these behemoths come a requirement to protect them in outdoor locations.
Large sized screens are ideal for outdoor digital signage as the bigger the screen, the more easily the TV is viewed from afar, and for this reason many outdoor screens are much larger than the LCD TVs we use at home.
But producing LCD enclosures for such giant-sized screens can be difficult as these devices require quite a lot of power and generate quite a large amount of heat, which has to be dissipated to prevent the screen from overheating.
Cooling is an essential aspect of providing protection for giant-sized LCD screens. Not only do there need to be a lot of cooling fans to ensure heat is transferred away, but some of filter has to allow fresh air in, and the heated air out.
Using any type of a filter on an outdoor LCD enclosure is made difficult by the need to ensure that water and other weather elements can’t penetrate the LCD enclosure and infest the TV.
Another difficulty faced in providing LCD enclosures for such large-sized devices is ensuring they are securely mounted. A screen of this size, plus the enclosure that houses it can exceed 200 kg (440 pounds) so has to be mounted securely.
Despite these challenges, 70” LCD enclosures are now commonly available and are ideal for protecting large-sized devices in not just outdoor locations but ensuring this heady investment is physically secured as well with a rugged steel body and shatterproof screen protecting from impacts and vandalism.
