Standardization in electronics is important for ensuring electrical items purchased from different suppliers are compatible with each other and different peripherals. Standardization allows electrical items such as DVD players to work with TVs, and computers to work with monitors.
To promote standardization in the video and monitor industry, a consortium of video adapter and monitor manufacturers set industry-wide standards. The Video Electronics Standards Association—VESA—define mounting options, hole patterns, cabling, sockets and jack locations for LCD and plasma displays.
Outdoor Digital Signage Enclosures and VESA
Designed to accommodate all sorts of LCD displays and screens, and allow their use outdoors, LCD enclosures make use of the VESA systems to enable the installation of screens from varying manufacturers.
The VESA standard ensures universal hole patterns in the rear of LCD and plasma screens. VESA is a pattern of four screw holes, 4mm in diameter, usually located in the centre of the monitor. Most LCD screens have a 100mm x 100mm VESA pattern, or 200mm x 200mm for larger screens, although for very large displays (70”+) 400mm x 600mm is used for better mounting security.
This means, whatever LCD you opt for, it should fit in the relevant sized LCD enclosure and securely mount on the VESA plate.
Many modern LCD enclosures now utilize more secure mounting systems than VESA; however, the standardization still applies as the mounting system ensures that any screen built to standard specification can be housed inside.
This standardization makes LCD enclosures a flexible method of housing LCD screens for use in outdoor environments. Because an LCD enclosure can accommodate almost any type of screen, it removes the need for highly expensive outdoor screens for use in external environments. Instead, standard consumer or commercial grade devices can operate as the LCD enclosure provides all the weather, temperature and physical protection these outdoor environments require.
