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 normally.
Note (3) The lamp frequency may produce interference with horizontal synchronization frequency from the
display, which might cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronization frequency and its harmonics
as far as possible.

(a) When the brightness becomes or lower than 50% of its original value.
(b) When the effective ignition length becomes or lower than 80% of its original value. (Effective
ignition length is defined as an area that has less than 70% brightness compared to the
brightness in the center point.)
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 reduce 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 Ѕ2 ± 10%;

6.2 POWER ON/OFF SEQUENCE
To prevent a latch-up or DC operation of LCD module, the power on/off sequence should follow the
conditions shown in the following diagram.
Note.
(1) The supply voltage of the external system for the module input should be the same as the definition of Vcc.
(2) Please apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation of the LCD turns off, the display may, instantly, function abnormally.
(3) In case of

Luminance is measured at the center measurement position “C” on the LCD panel. The optical
axis of the luminance meter shall be aligned with the normal of the panel surface. The measuring
distance between the photometer and the surface of the panel is defined as:
Md (cm) = diagonal of the panel (cm) X 1.5 with minimum distance 50 cm.
The panel is rotated around a vertical axis which passes the center of the display by changing
the azimuthal angle to +30q. The distance between the panel and the photometer remains
unchanged and the measured point is exact the same as the previous measured point.
The photometer is then rotated by changing its azimuthal angle with the fixed distance to the
panel. Luminance at points “L” and “R” are given:

8. PRECAUTIONS
8.1 ASSEMBLY 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.
8.2 SAFETY PRECAUTIONS
(1) 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.
(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 washed away thoroughly with soap.
(3) After the module’s end of life, it is not harmful in case of normal operation and storage.
