Don't exceed “the recommended operation conditions” in this specification. (The LCD module should be used within
“the recommended operation conditions”.)
The performance and quality of the LCD module are warranted only when the LCD module is used within “the
recommended operation conditions”. Toshiba Matsushita Display Technology never warrants the performance and
quality of the LCD module when you use the LCD module over “the recommended operation conditions”, although
within “the absolute maximum rating”.
To use the LCD module over “the recommended operation conditions” may have bad influence on the characteristics
and reliability of the LCD module and may shorten the life of the LCD module.
Therefore, when designing the whole set, not to be over “the recommended operation conditions”, you should fully
take care of supply voltage change, characteristic of connection parts, serge of input-and-output line , and surrounding
temperature.
9) FEVER OF THE LED BACKLIGHT
LCD module’s upper and lower end portions (LED portions) get hot. The LEDs are built in the upper and lower end
portions of LCD module as backlight sources.
While LEDs are lit and immediately after turned off, the face of LCD module (display surface), top and bottom faces,
metal portions of right and left side faces, and metal portion of LED unit cover(s) on the back are hot and require
caution.
In case of touching (working on) such portion by necessity, surely disconnect the power to the LCD module
beforehand, protect hands (skin) with low thermal conductive gloves etc. or wait until the temperature of metal portion
gets as low as room temperature, and then touch (work on) the portion while being careful to prevent electrostatic
breakdown.
For Designing the System
2-1 DESIGNING ENCLOSURE
1) MOUNTING HOLES

cause the deterioration of the polarizer laminated on LCD’s panel or internal parts of the LCD module. Prior
confirmation is required.
5) GAS GENERATED FROM CASING /PACKAGING MATERIAL FOR A SET
Some materials used for packaging (for which sulfuric acid is used in the recycling process) generate gases that may
cause the deterioration of the polarizer laminated on LCD’s panel or internal parts of the LCD module. Prior
confirmation is required.
2-2. DESIGNING POWER SUPPLIES AND INPUT SIGNALS TO LCD MODULE
1) CAPACITY OF POWER SUPPLY
The fuse (KAMAYA /Type:FCC16152AB＜TP＞) is attached at the power supply line in the LCD module.
The sufficient electric capacity is needed for effective operation of this fuse. As for this fuse, there is no effect in the
former circuit. As an example, some parts such as I/F connector may be damaged with fire and/or smoke when the
power supply is shorted at I/F connector part. Have a suitable protection circuit also in the set side for accident
prevention. In equipping the set side with a fuse, please choose the fuse of suitable specification so that a fuse does
not blow by the rush current at operation start.

2) SEQUENCE OF POWER SUPPLIES AND INPUT SIGNALS
Power-supply lines should be designed as follows.
Power supplies should always be turned on before the input signals are supplied to LCD module, and the input
signals should be disconnected before power supplies are turned off.
If this sequence is not followed, it may cause mis-operation of the panel.
Refer to "Sequence of Power Supplies and Signals" described in this Specification for details.
In addition, refer to individual specifications for unused terminals.
3) IMAGE STICKING IN A DISPLAY
Design the system not to display the same pattern for a long time.
Continuing the same pattern display for a long time or inputting the signals besides recommendation may cause the
phenomenon “image sticking” which remains vaguely after changing patterns.
4) GROUNDING FOR METAL FRAME(BEZEL)
Connecting metal frame (front bezel or/and rear case) of LCD module to ground is strongly recommended.
Generally grounding from metal frame of LCD module effects to improve endurance of ESD, various noise and
radiation interference from system design.
However, there are the above performance differences by system structure, so final conclusion for the grounding
should be decided after confirmation of matching with system side.

2-3 DESIGNING FOR BETTER VISIBILITY
1) PANELANGLE
Visibility of LCD module deeply depends on the viewing directions. The position and the angle of LCD module in the
system should be designed so that the best visibility can be obtained at the actual usage.
2) WINDOW OPENING
Dimensions of window opening of the system's enclosure should be designed as smaller than "Viewing Area" and
larger than "Active Area" specified in individual specification in order to prevent that a part of screen is interrupted by
the enclosure and disappears.
3) PROTECTIVE COVER/ ULTRA-VIOLET CUT FILTER
In case of severe environmental condition like outdoor usage, a proper transparent protective cover (lens) over LCD
module is recommended, to prevent scratches, invasion of dust and water, etc, between the system housing and the
LCD module.
It is recommended to apply an ultra-violet filter (less than 390nm cut) onto the LCD module, for outdoor operation.
Strong ultra-violet radiation may damage the panel. However, in that case, transmittance-luminance will decrease.
Careful selection of material is required.
Don’t expose any parts, except the viewing area, into the direct sunlight, otherwise deterioration may occur.
2-4 DESIGNING LED POWER SUPPLY CIRCUIT
Make a design of stopping output, when an LED driving circuit becomes no-load (LED, FPC damage).
When the voltage input continuously with no-lighting LED, it may be smoke or fire.
For overcurrent protection, make a design of LED driving circuit with protective circuit (overcurrent
detector etc.).
To drive LED backlight, apply constant electric current by the following circuit diagram as reference. Please refer to
technical note of BD6583MUV (ROHM Co., Ltd.).
For Installation in Assembly

3-2 CAUTIONS TO PREVENT FROM ELECTROSTATIC DESTRUCTION UNDER ASSEMBLY WORK
Consider the following to prevent the static electricity from generating under assembly work. High-voltage static
electricity discharge destroys the circuit inside the module and it may cause failures
1) HUMIDITY
Maintain a work place in the range of 50 to 70% of relative humidity, to prevent generation and discharge of static
electricity.
2) GROUNDING
2-1) Cover the floor of a work area and a work desk with a conductive mat, and ground them, through resistance with
range of 0.5 MΩto 1MΩ, to prevent discharge all at once.
2-2) Workers must wear a grounded wrist band.
2-3) Ground all metallic tools, jigs and equipment, such as a soldering iron and a screw driver, jigs, conveyors, or
metallic work benches, which are to be used for assembly work.
3) IONIZER
Using ionizer (an antistatic blower) is recommended at working area in order to reduce electro-static voltage.
4) REMOVING PROTECTION FILM
The protection film is stuck on an LCD panel before its shipment to prevent dust or scratch on the panel during
transportation, assembly work and otherwise. Remove a protection film on an LCD panel near the last process of
an assembly to prevent dust and scratch on the panel.
However, remove the film in advance in case of a set attached a module is inserted into high temperature chamber
for aging etc. If it is left without removing the film, it may cause irregular polarizer surface.
When removing the protection film, peel off the film from its edge, using round-ended tweezers with Teflon coating or
a cellophane tape attached on the edge of the protection film, carefully and slowly, spending more than 3 seconds.
In peeling off the protection film, blow the film using ionizer to eliminate ESD from the film.
Removal which does not comply with the above procedure may generate ESD and damage electric circuit of a LCD
module.
5) Do not touch bare metal portions of examination /inspection equipment. It causes to discharge electric charge of an
object or a human body.
6) Do not touch the mounting parts of PCB LCD module, circuit patterns or connector terminals with worker’s hand or
conductive tools.
3-3 DUST AND STAIN PREVENTION
1) WORKING AREA
Handle the LCD module in the room without metallic dust. Especially when metallic dust adheres to the LCD module,
an internal electric circuit makes short-circuited and it may cause failures.
2) FINGER PRINT
Handle the LCD module fingerstalls or soft and dust-free gloves that do not produce dust when performing incoming
inspection of modules or assembling sets. Handling them with bare hand may damage module display quality.

In case of LCD module long period operation, discoloration of light guide or optical sheet will be happened (due to
ultra violet and heat from FL tube). As the result, there is a possibility to have out of specification for the optical
characteristic as “5.2”. But this is not irregular phenomena.
4) LED LIFE
Please note that LED life will be shorter than the average life described in the Specification if the ambient
temperature is higher than 25°C.
Moreover, when LED current exceeded a recommended electric current, LED life will be shorter than the average life.
5) LCD MODULE REPLACEMENT FROM SYSTEM
When replacing LCD module, turn off supply voltage and input signal to the LCD module, surely disconnect the
power supply to the circuit for lighting the backlight (not only by turning off the control signal to ON/OFF terminal etc.),
and then replace the LCD module.
For Transportation and Storage
1) STORAGE UNDER HIGH TEMPERATURE AND HIGH HUMIDITY
Be careful not to store a LCD module for a long time (about one month or more) under the condition of high
temperature and high humidity (35 ºC or more, 70% or more of relative humidity). This may deteriorate display
quality.
When it is necessary to store unavoidably for a long term, in the state of packing by our company (before opening),
store it within the range of 0 ºC to 35 ºC and in the dry place of 70% or less of relative humidity.
2) SOLIDIFICATION ON THE LIQUID CRYSTAL IN CRYOGENIC CONDITION
Since a temperature lower than a rated storage temperature described in this Specification may damage a LCD
module liquid-crystal-display panel due to the solidification or contraction etc. on liquid crystal, be careful not to
leave it in such a place.
3) BE CAUTIOUS OF STRONG ULTRAVIOLET
Be careful not to expose a LCD module to the sunlight or a fluorescent light directly to protect a LCD module from
strong ultraviolet, when storing modules for a long term.
4) CLEANLINESS
Keep the LCD module in clean place, because any dust, hard particle may damage the polarizer, or dust invades the
inside of the LCD module.
∗5) CONDENSATION OF WATER
The modules should be stored under a condition which no condensation of water is allowed. It may cause
mis-operation or defects. Be especially careful not to make a module work under the condition that condensation of
water appears.
6) REPACKAGING
Use the original packing box, material, and method when repacking for transporting and storing it again.
7) NOTES FOR THE ADOPTION OF NEW PACKING MATERIAL

Note 1) If DE is fixed to “H” or “L” level for certain period while CLK is supplied, the panel displays black with some flicker.
Note 2) Don’t fix CLK to “H” or “L” level while the VDD(+3.3V) is supplied.
If CLK is fixed to "H" or "L" level for certain period while DE is supplied, the panel may be damaged.
When It holds on, DC voltage supplies to liquid crystal materials and It may cause damage to liqud crystal
materials.
Note 3) Display area address is as follows.
Note 4) Do not make tv, th and tvds fluctuate.
Iftv, th and tvds are fluctuate, the panel displays black.
Note 5) In case of using the long frame period, the deterioration of display quality, noise etc. may be occurred.
Note 6) CLK count of each Horizontal Period (th) should be always the same.
Vertical blanking term should be “n” X “Horizontal Period” (th). (n: integer)
Frameperiod(tv) should be always the same.
