Note (2) The voltage shown above should be applied to the lamp for more than 1 second after startup.
Otherwise the lamp may not be turned on.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the
display, and this may cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronous frequency and its harmonics as far
as possible.

C and IL = 7.0 mA rms until one of the following events occurs:
(a) When the brightness becomes or lower than 50% of its original value.
(b) When the effective ignition length becomes ≦ 80% of its original value.
(The effective ignition length is a scope that luminance is over 70% of that at the center point.)
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 producing 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
which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may
produce interface with horizontal synchronous frequency and as a result this may cause beat on the
display. Therefore lamp frequency shall be as away possible from the horizontal synchronous
frequency and from its harmonics in order to prevent interference.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and redu ce its
leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within √2 ± 10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.

(2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation of the LCD turns off before the backlight turns off, the display may momentarily become abnormal
screen.
(3) In case of VCC = off level, please keep the level of input signals on the low or keep a high impedance.
(4) T4 should be measured after the mo dule has been fully discharged between power off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.

10. PRECAUTIONS
10.1 ASSEMBL Y AND HANDLING PRECAUTIONS
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assemble or install module into user’s system can be only in clean working areas. The dust and oil
may cause electrical short or worsen the polarizer.
(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and Backlight will
be damaged.
(4) Always follow the correct power sequence when LCD module is connecting and operating. This can
prevent damage to the CMOS LSI chips during latch-up.
(5) Do not pull the I/F connector in or out while the module is operating.
(6) Do not disassemble the module.
(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and
easily scratched.
(8) It is dangerous that moisture come into or contacted the LCD module, because moisture may damage
LCD module when it is operating.
(9) High temperature or humidity may reduce the performance of module. Please store LCD module within
the specified storage conditions.
(10) When ambient temperature is lower than 10ºC may reduce the display quality. For example, the
response time will become slowly, and the starting voltage of CCFL will be higher than room
temperature.
10.2 SAFETY PRECAUTIONS
(1) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while
assembling with inverter. Do not disa ssemble the module or insert anything into the Backlight unit.
(2) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In
case of contact with hands, skin or clothes, it has to be washe d away thoroughly with soap.
(3) After the module’s end of life, it is not harmful in case of normal operation and storage.
