BACKLIGHT CHARACTERISTICS
This module is used the backlight with 4 Lamps.
Please follow the characteristics of 1 Lamp as below.
Ta=25 degC
ITEM SYM. CONDITIONS MIN TYP MAX UNIT NOTE
Lamp voltage VL - 730 - Vrms at IL=6.5 mArms
Lamp current IL 3.0 - 7.0 mArms Recommended value
Operating frequency fL 40 - 65 kHz Recommended value
Start up voltage VS - - 1800 Vrms at Ta=0 degC
Lamp life tOL 50000 - - Hours at IL=6.5 mArms
[Note 1] Backlight driving conditions (operating frequency fL especially) may interfere with
horizontal frequency fH, causing the beat or flicker on the display.
Therefore the operating frequency fL shall be adjusted in relation to horizontal
frequency fH to avoid interference. And, In case you drive 4 Lamps with 4 separate
transformers, please make sure that frequency and phase of both transformers
match each other.
[Note 2] The inverter open voltage should be larger than start up voltage, otherwise backlight
may blinking for a moment after turns on or not be turned on. And this voltage
should be applied to lamp for more than 1 second to start up, otherwise backlight
may not be turned on.
[Note 3] If driving current waveform is asymmetrical, mercury deviation inside of Lamp will
incline to one side and consequently abnormal lighting may occur.
To prevent such unfavorable lighting, driving current waveform is asked to have
unbalance rate of less than 10% and wave-height rate of less than 2 +/- 10%.
And this driving waveform shall be confirmed in your system.
Unbalance rate = | Ip - I-p | / IL x 100 (%)
Ip Wave-height rate = Ip (or I-p) / IL
Ip : High peak value
I-p
I-p : Low peak value
IL : Effective value

When the power is off, logic input must be kept at either low level or high impedance.
Power sequence for Lamp (backlight) is not specified especially, however it is
recommended to consider some timing difference between logic input as shown above.
If backlight lights on before LCD starts function, or if backlight is kept on after LCD
stopped function, screen may look white for a moment or abnormal image may be
displayed.
This is caused by variation in output signal from timing generator at logic input on or
off. It does not cause damage to liquid crystal molecule and driving circuit.

PRECAUTIONS (INSTRUCTIONS FOR SAFE AND PROPER USE)
1. Instructions for safety
(1) Please do not disassemble or modify LCD module to avoid the possibility of
electric shock, damage of electronic components, scratch at display surface and
invasion of foreign particles. In addition, such activity may result in fire accident
due to burning of electronic component.
LCD module disassembled or modified by customer is out of warranty.
(2) Please be careful in handling of LCD module with broken glass.
When the display glass breaks, please pay attention not to injure your fingers. The
display surface has the plastic film attached, which prevents dispersion of glass
pieces, however touching broken edge will injure your fingers. Also Lamp (Cold
Cathode Fluorescent Lamp) is made of glass, therefore please pay attention in
the same way.
(3) Please do not touch the fluid flown out of broken display glass.
If the fluid should stick to hand or clothes, wipe off with soap or alcohol
immediately and then wash it with water. If the fluid should get in eyes, wash eyes
immediately with pure water for more than 15 minutes and then consult the doctor.
(4) Please make secure connection of Lamp connector.
Please make sure that Lamp connector from LCD module is connected with
output connector on inverter circuit securely. Poor connection may cause smoke
or fire accident due to high voltage in circuit. If connection may not be secure,
please switch off the power supply for LCD module and Lamp and then make
secure connection.
Please do not make connection with another connector than recommended
mating connector.
(5) Lamp contains mercury inside. Please follow regulations or rules established by
local autonomy at its disposal.
(6) Please be careful to electric shock.
Before handling LCD module, please switch off the power supply.
Since high voltage is applied to Lamp terminal, cable, connector and inverter
circuit in operation mode, touching them will cause electric shock.
2. Instructions for designing
(1) Mounting of LCD
Please fix LCD module at all mounting flanges shown in this specification for
installation onto system. The used screws should have proper dimensions.
Furthermore, designing of mounting parts should be adequate so that LCD
module is not warped or twisted, to achieve good display quality.
(2) Polarity of power supply for Lamp
Please give careful consideration in designing so that each polar of cable should
be connected correctly at assembling (i.e. high voltage side is connected to high
voltage side and low voltage side is connected to low voltage side). Since longer
Lamp cable may cause insatiable start-up of Lamp and reduction of brightness,
please make cable short as much as possible.
PM190SX-70N01 Ver.1 Page 12/16
One step solution for LCD / PDP / OLED panel application: Datasheet, inventory and accessory! www.panelook.com
Global LCD Panel Exchange Center www.panelook.com
(3) Designing of power supply circuit for Lamp
Please design the circuit so that high voltage output can be kept for more than 1
second. The shorter time may not start up Lamp. The driving inverter circuit is
recommended to be the type which Lamp current can be controlled.
The type which voltage is controlled is not recommended, because it may cause
big current under high temperature and insatiable start-up of Lamp under low
temperature.
(4) Heat radiation
Lamp generates heat at lighting and causes temperature rise inside system.
Therefore, designing to radiate heat like radiation slits at cabinet is recommended
to meet the specified operating temperature range for LCD module.
(5) Noise on power line
Spike noise contained in power line causes abnormal operation of driving circuit
and abnormal display. To avoid it, spike noise should be suppressed below VDD
+/- 200mVp-p. (In any case, absolute maximum rating should be kept.)
(6) Power sequence
Before LCD module is switched on, please make sure that power supply and input
signals of system, testing equipment, etc. meet the recommended power
sequence.
(7) Absolute maximum rating
Absolute maximum rating specified in this specification has to be kept in any case.
It shows the maximum that cannot be exceeded.
Exceeding it may cause burning or non-recoverable break of electronic
components in circuit. Please make system design so that absolute maximum
rating is not exceeded even if ambient temperature, input signal and components
are varied.
(8) Protection for power supply
Please study to adapt protection for power supply against trouble of LCD module,
depending on usage condition of system. Fuse installed on LCD module should
be never modified. Any modification to make the function of fuse ineffective may
cause burning or break of printed wiring board or other components at circuit
trouble.
(9) Protection against electric shock
High voltage is applied to Lamp connector, inverter circuit and Lamp at lighting.
Please make design not to expose or be accessible to such high voltage parts to
avoid electric shock.

When LCD module is used under severe condition like outdoor, it is
recommended to use transparent protection cover over display surface to avoid
scratches and invasion of dust and water. In addition, when LCD module is
exposed to direct sun light for long time, use of cut-off filter for ultraviolet rays is
also recommended. Please be careful not to get condensation.
3. Instructions for use and handling
(1) Protection against Static electricity
C-MOS LSI and semiconductors are easily damaged by static discharge. LCD
module should be handled on conductive mat by person grounded with wrist strap
etc. to avoid getting static electricity. Please be careful not to generate static
electricity during operation.

(2) Protection against dust and stain
LCD module should be handled in circumstance as clean as possible.
It is recommended to wear fingerstalls or ductless and soft gloves before handling
to avoid getting dust or stain on display surface.
(3) Protection film for display surface
It is recommended to remove protection film at nearly final process of assembling
to avoid getting scratch or dust. To remove film, please pick up its edge with
dull-head tweezers or cellophane tape at first and then remove film gradually
taking more than 3 seconds. If film is removed quickly, static electricity may be
generated and may damage semiconductors or electronic components.
(4) Contamination of display surface
When display surface of LCD module is contaminated, please wipe the surface
softly with cotton swab or clean cloth. If it is not enough, please take it away with
cellophane tape or wipe the surface with cotton swab or clean cloth containing
benzine. In this case, please be careful so that benzine does not get in inside of
LCD module, because it may be damaged.
(5) Water drop on LCD surface
Please do not leave LCD module with water drop. When the display surface gets
water drop, please wipe it off with cotton swab or soft cloth immediately, otherwise
display surface will be deteriorated.
If water gets in inside of LCD module, circuit may be damaged.
(6) Please make sure that LCD module is not warped or twisted at installation into
system. Even temporary warp or twist may be the cause for failure.
(7) Mechanical stress
Please be careful not to apply strong mechanical stress like drop or shock to LCD
module. Such stress may cause break of display glass and Lamp or may be the
cause for failure.
(8) Pressure to display surface
Please be careful not to apply strong pressure to display surface. Such pressure
may cause scratches at surface or may be the cause of failure.
(9) Protection against scratch
Please be careful not to hit, press or rub the display surface with hard material like
tools. In addition, please do not put heavy or hard material on display surface, and
do not stack LCD modules. Polarizer at front surface can be easily scratched.
(10) Plugging in of connector
Please be careful not to apply strong stress to connector part of LCD module at
plugging in or out, because strong stress may damage the inside connection. At
plugging in connector, place LCD module on the flat surface and hold the
backside of connector on LCD module. Please make sure that connector is
plugged in correctly. Insecure connection may be the cause for failure during
operation.
In addition, please be careful not to put the connecting cable between cabinet of
system and LCD module at installing LCD module into system.
(11) Handling of Lamp cable and FPC (Flexible Printed Circuit)
Please be careful not to pull or scratch Lamp cable, because Lamp or soldered
part of cable may be damaged consequently.
Also FPC should not be pulled or scratched.
(12) Switching off before plugging in connector
Please make sure that power is switched off before plugging in connector.
If power is on at plugging in or out, circuit of LCD module may be damaged.
When LCD is switched on for test or inspection, please make sure that power
supply and input signals of driving system meet the specified power sequence.

(13) Temperature dependence of LCD display
Response speed (optical response) of LCD display is dependent on temperature.
Under low temperature, response speed is slower.
Also brightness and chromaticity change slightly depending on temperature.
(14) Slow light-up of Lamp under low temperature
Under low temperature, start-up of Lamp gets difficult. (The time from switch-on to
stable lighting becomes longer.)
As characteristic of Lamp, operation under low temperature makes the life time
shorter. To avoid this, it is recommended to operate under normal temperature.
(15) Condensation
LCD module may get condensation on its display surface and inside in the
circumstance where temperature changes much in short time.
Condensation can cause deterioration or failure. Therefore, please be careful not
to get condensation.
(16) Remaining of image
Displaying the same pattern for long time may cause remaining of image even
after changing the pattern. This is not failure but will disappear with time.
4. Instructions for storage and transportation
(1) Storage
Please store LCD module in the dark place of room temperature and low humidity
in original packing condition, to avoid condensation that may cause failure.
Since sudden temperature change may cause condensation, please store in
circumstance of stable temperature.
(2) Stacking number
Since excessive weight causes deformation and damage of carton box, please
stack only up to the number stated on carton box for storage and transportation.
(3) Handling
Since LCD module consists of glass and precise electronic components, it will be
damaged by excessive shock and drop. Therefore, please handle the carton box
carefully to minimize shock at loading, reloading and transportation.
