(7) When the surface becomes dusty, please wipe gently with absorbent cotton or
other soft materials like chamois soaks with petroleum. Normal-hexane is
recommended for cleaning the adhesives used to attach front / rear polarity.
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 miss 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 or 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.
(8) A screw which is fastened up the steels should be a machine screw. (if not, it
causes metallic foreign material and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.
9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to electrostatic
discharge. Make certain that treatment persons are connected to ground through
wrist band etc. And don't touch interface pin directly.
