Why
are there fogs
on
the
screen
？
In
order
to
ensure
the
safety
of
the
screen,
this
product
adds
a
layer
of
toughened
glass
on
the
outside
of
the
screen,
also
in
order
to
ensure
heat
dissipation,
there
must
be
a
certain
gap
between
the
two,
which
is
used
to
reserve
the
air
passage
for
air
convection.
The
main
reason
for
the
fog
is
that
there
is
a
temperature
difference
between
the
screen
temperature
and
the
outside
temperature,
and
hot
air
condenses
on
the
surface
of
the
glass
at
a
lower
temperature,
which produces
water
mist.
Water
mist
does
not
affect
the
normal
use,
the
fog
will
slowly
evaporate
away
after
a
few
hours.
