Operation Precautions
(1) Do not pull the I/F connector in or out while the LCD module is operating.
(2) Always follow the correct power on/off sequence when LCD module is connecting and
operating. This can prevent the CMOS LSI chips from damage during latch-up.
(3) Response time depends on the temperature. (In lower temperature, it becomes longer.)
(4) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
(5) 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.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference shall be done by system manufacturers. Grounding and shielding methods
are very important to minimize the interference.
(7) Please do not give any mechanical and/or acoustical impact to module. Otherwise,
module can’t be operated its full characteristics perfectly.
(8) 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.
(9) Do not display the fixed pattern for a long time because it may cause image sticking.
(10) In order to prevent image sticking, periodical power-off or screen save is needed after
fixed pattern long time display.
(11) Black image or moving image is strongly recommended as a screen save.
(12) Static information display recommended to use with moving image. Cycling display
between 10 minutes' information (static) display and 10 seconds' moving image.
(13) Background and character (image) color change is recommended. Use different colors
for background and character, respectively. And change colors themselves periodically.
(14) LCD system is required to place in well-ventilated environment. Adapting active cooling
system is highly recommended.
(15) Product reliability and functions are only guaranteed when the product is used under
right operation usages.
(16) If product will be used in extreme conditions, such as high temperature/ humidity, shock
and vibration it is strongly recommended to contact Litemax for filed application
engineering advice. Otherwise, its reliability and function may not be guaranteed.
Extreme conditions are commonly found at airports, transit stations, taxi-top, in vehicle
and controlling systems.
