Note (6) The waveform of the voltage output of inverter must be area-symmetric and the design of the
inverter must have specifications for the modularized lamp. The performance of the Backlight,
such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter for
the lamp. All the parameters of an inverter should be carefully designed to avoid generating too
much current leakage from high voltage output of the inverter. When designing or ordering the
inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the
inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module
should be operated in the same manners when it is installed in your instrument.
The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter,

produce interface with horizontal synchronous frequency and as a result this may cause beat on the

Note (1) Please avoid floating state of interface signal at invalid period.
Note (2) When the interface signal is invalid, be sure to pull down the power supply of LCD Vcc to 0 V.
Note (3) The Backlight inverter power must be turned on after the power supply for the logic and the
interface signal is valid. The Backlight inverter power must be turned off before the power supply
for the logic and the interface signal is invalid.
Note (4) Sometimes some slight noise shows when LCD is turned off (even backlight is already off). To
avoid this phenomenon, we suggest that the Vcc falling time had better to follow

8. PRECAUTIONS
8.1 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
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.
8.2 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.
8.3 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 inverter. Do not disassemble the module or insert anything into the Backlight unit.
