4.1.3 Requirements of Temperature and Humidity
1) There are good air-conditioning environment and ventilation within the maintenance
channel of video wall display system, meantime guarantee to avoid condensation of
the screen caused by temperature instability.
2) The ideal working environment of video wall display system is 22
℃
±4
℃，
and the
ideal relative humidity is 30% to 70% without condensation. The general environment
should not have relatively large temperature difference and sudden change of
humidity, while both temperature and humidity change are slow.
4.1.4 Light Requirements
1) To achieve good effect of viewing from viewing area, we recommend you to locate
the dark area 4m in front of the screen, no fluorescent tube allowed within the area.
We also recommend the installation of built-in light parallel to the screen set with
independent switcher. Light cannot light up directly on the screen. Make the light as
back as possible to the screen.
2) Control lights of entire hall in the direction parallel to the screen by groups; do not use
relatively strong source of light, and the principal is: supply enough light to the
working area, meanwhile not affecting the screen.
3) Possible light from the two sides of hall (i.e. window), should be covered (i.e. by
curtain). (Sunshine affect screen the most.)
4.1.5 Decoration Requirements
1) The thickness of wall behind the screen window of video wall display system is
suggested to be 80mm, and the wall must be firm, while the dimensions of window
stay the same.
2) Before video wall installation, reserved installation window dimension on designated
wall: (
1024.0×4
+40)mm horizontal X (
578.6×2
+40)mm vertical=
（
2088.0mm×
1197.2mm
）
, which is 40mm longer than each side of actual full screen size on video
wall display wall. When splicing walls have more than 10 rows, the reserved
installation window should be larger than the total size of splicing wall for convenient
installation. (Construction drawings attached)
3) After the video wall display wall has been installed in place, local decoration company
is going to close interstice around the screen (make zero leakage of light), and
decorating if needed. The entire decoration style is neat, in cool color, bright and
simple. The ceiling can be in ivory, silver, or light grey with any materials as long as it
is matte without strong reflection. The wall color should be bright and simple with dark
lines, and combined with sound absorbing materials while the wall is mainly matte.
The floor had better use anti-static materials, covered by carpet of dark color or other
non-reflective materials.
4) Local installation environment should be clean without dust, spray paint or lime
before installation. Within the installation area of display wall, there should be no
working at height. The fire fighting system is supposed to pass security test.
Air-conditioner is supposed to be available for use and power supply is stable and
