(6) Do not touch, push or rub the exposed polarizer 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 polarizer. 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.
9-2. Operating Precautions
(1) The spike noise causes the mis-operation of circuits. It should be lower
than following voltage:
V=±200mV (Over and under shoot voltage)
(2) Response time depends on the temperature.(In lower temperature, it
becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes
lower.) And in lower temperature, response time (required time that
brightness is stable after turned on) becomes longer.
(4) Be careful for condensation at sudden temperature change. Condensation
makes damage to polarizer or electrical contacted parts. And after fading
condensation, smear spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely
to occur.
(6) Module has high frequency circuits. Sufficient suppression to the
electromagnetic interference shall be done by system manufacturers.
Grounding and shielding methods may be important to minimize the
interference.
(7) Please do not give any mechanical and/or acoustical impact to LCM.
Otherwise, LCM can’t be operated its full characteristics perfectly.
