Note (2) If the PWM control duty ratio is less than 10%, there is some possibility that acoustic noise or
backlight flash can be found. And it is also difficult to control the brightness linearity.
Note (3) If PWM control frequency is applied in the range less than 1KHz, the “waterfall” phenomenon on the
screen may be found. To avoid the issue, it’s a suggestion that PWM control frequency should follow
the criterion as below.

Note (1) Please follow the power on/off sequence described above. Otherwise, the LCD module might be
damaged.
Note (2) Please avoid floating state of interface signal at invalid period. When the interface signal is invalid, be
sure to pull down the power supply of LCD VCCS to 0 V.
Note (3) The Backlight converter power must be turned on after the power supply for the logic and the interface
signal is valid. The Backlight converter power must be turned off before the power supply for the logic and
the interface signal is invalid.
Note (4) Please follow the LED converter power sequence as above. If the customer could not follow, it might
cause backlight flash issue during display ON/OFF or damage the LED backlight controller

9. PRECAUTIONS
9.1 HANDLING PRECAUTIONS
(1) The module should be assembled into the system firmly by using every mounting hole. Be careful not to
twist or bend the module.
(2) While assembling or installing modules, it can only be in the clean area. The dust and oil may cause
electrical short or damage the polarizer.
(3) Use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and assembly
process.
(4) Do not press or scratch the surface harder than a HB pencil lead on the panel because the polarizer is
very soft and easily scratched.
(5) If the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. Do not use
Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might

Approval
permanently damage the polarizer due to chemical reaction.
(6) Wipe off water droplets or oil immediately. Staining and discoloration may occur if they left on panel for a
long time.
(7) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case
of contacting with hands, legs or clothes, it must be washed away thoroughly with soap.
(8) Protect the module from static electricity, it may cause damage to the C-MOS Gate Array IC.
(9) Do not disassemble the module.
(10) Do not pull or fold the lamp wire.
(11) Pins of I/F connector should not be touched directly with bare hands.
9.2 STORAGE PRECAUTIONS
(1) High temperature or humidity may reduce the performance of module. Please store LCD module within
the specified storage conditions.
(2) It is dangerous that moisture come into or contacted the LCD module, because the moisture may
damage LCD module when it is operating.
(3) It may reduce the display quality if the ambient temperature is lower than 10 ºC. For example, the
response time will become slowly, and the starting voltage of lamp will be higher than the room
temperature.
9.3 OPERATION PRECAUTIONS
(1) Do not pull the I/F connector in or out while the 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) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while
assembling with converter. Do not disassemble the module or insert anything into the Backlight unit.
