Please do not touch, push or rub polarizer surface
with materials over HB hardness.

   2-       Keep clean the surface.
Please wear rubber glove when touch the surface of
LCD screen. Please use soft and anti-static material
as cleaner.

  3-        Keep out of water.
Water on/in the LCD may cause electrical short or
corrosion. Please wipe out dry or water carefully.

  4-        Prevent swift Temperature &
