(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 df 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 soaked with petroleum benzene. Normal-hexane is recommended
for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone,
toluen 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.
15.2 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 or spot
will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) A module has high frequency circuit. It might be necessary to shield the
electromagnetic noise in your integrating system.
(7)
When a Backlight unit is operating, it may make sounds. It might be necessary to shield your
integrating system to cut down the noise.
15.3 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 wristband etc . . And
don’t touch I/F pin directly.
15.4 STORAGE
When storing modules for a long time, the following precautions should be followed.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light.
Keep the temperature between 5
o
C and 35
o
C at normal humidity.
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
15.5 HANDLING PRECAUTIONS FOR PROTECTION FILM
(1) When the protection film is peeled off, static electricity is generated between the
film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded
and with well ion- blown equipment or in such a condition, etc..
