Precaution
Please pay attention to the followings when you use this TFT LCD module
1. 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) Module has high frequency circuits. System manufacturers shall do sufficient
suppression to the electromagnetic interference. 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.
(9) Please do not set LCD on its edge
(10) Partial darkness may happen during 3~5minutes when LCM is operated initially in
condition that luminance is under 40% at low temperature (under 5℃).This
phenomenon which disappears naturally after 3~5 minutes is not a problem about
reliability but LCD characteristic.
2. Handing Precaution For Protection
(1) The protection film is attached to the bezel with a small masking tape. 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.
