9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1) You must mount a module using holes arranged in four cornersor four
sides.
(2) You should consider the mounting structure so that uneven force (ex.
Twisted stress) is not applied to the module. And the case on which a
module is mounted should have sufficient strength so that external force is
not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in
order to protect the polarizer. Transparent protective plate should have
sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satisfy the temperature
specification.
(5) Acetic acid type and chlorine type materials for the cover case are not
desirable because the former generates corrosive gas of attacking the
polarizer at high temperature and the latter causes circuit break by
electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or
anything harder than HB pencil lead. And please do not rub with dust
clothes with chemical treatment. Do not touch the surface of polarizer for
bare hand or greasy cloth.(Some cosmetics are detrimental to the
polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent
cotton or other soft materials like chamois soaks with petroleum benzine.
Normal-hexane is recommended for cleaning the adhesives used to attach
front / rear polarizers. Do not use acetone, toluene and alcohol because
they cause chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact
with polarizer causes deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient
strength.
