(1) The display board and the joint part of
the display board and the building should be strictly waterproof and
leakage-proof. The display sign should take excellent dewatering measure, so
that ponding can be smoothly let out.
(2) Lightning arrester should be installed
on the display board as well as the building. The main part and the shell of
the display board should be connected to the ground, and the ground resistance
should be lower than 3O, so that the large current caused by the thunder can be
timely discharged.
(3) A ventilating device should be
installed to cool the display and make sure that the internal temperature of
the outdoor advertising led display stays between -10℃ and 40℃. The upper
part of the back of the display sign should be installed with axial flow fan to
expel heat.
(4) A industrial-grade integrated
circuit chip whose working temperature is between -40℃ and 80℃ should be
used to make sure that the display board can also be started even in low
temperature winter.
(5) To make sure that the display can be
viewed from long distance under strong light condition, super bright led should
be used.
