Using a digital screen for advertising, promotion or providing information is becoming increasingly common, thanks in part to the falling cost of LCD and plasma type screens. The flat-screen TVs are also becoming more durable with commercial grade screens able to be left on 24 hours-a-day and have lifetimes far longer than consumer TVs.
This robustness enables LCD TVs to be used as signage displays in retail units and other locations, where the ambient environment is around room temperature and the locations are free from dust or other elements; however, not all locations where this digital signage is used is as friendly to these commercial screens as this.
Often digital signage is used in concourses, dusty environments and even outside as outdoor digital signage, so protecting the screen is essential if they are to operate without fault.
One of the simplest methods of providing protection is the LCD enclosure. LCD enclosures are now a common sight in all sorts of locations from outdoor digital signage along high streets or outside transport hubs, to inside concourses and factory locations.
As the name implies, an LCD enclosure encloses an LCD screen (or a plasma, or LED backlight type LCD) and provides all the protection required for even the hardiest of locations.
Outdoor digital signage for advertising or information is becoming increasingly common. LCD Enclosures allow screens outdoors because they are waterproof and prevent any moisture from getting inside the enclosure. But outdoor environments also have other hazards that a screen should be shielded against:
Cold and Heat
Excessive temperatures are not just a problem for outdoor digital signage, although high temperatures of summer and frozen winters do have to be considered when using an outdoor screen, but other locations such as industrial locations have furnaces or chillers where a normal screen could just not cope with.
Apart from excessive temperatures industrial areas contain other hazardous elements. Dust, for instance, will cause a screen to overheat and can cause short circuits. Industrial areas can also contain moisture or even water jets when items are washed down but an LCD enclosure will allow LCD screens to endure all of the above.
