FOR SAFETY
LCD module is generally designed with precise part s to achieve light weighted thin mechanical dimensions.
In using our Modules, make certain that you fully understand and put into practice the warnings and safety precautions detailed
in Engineering Information No.EE-N001,"CAUTIONS AND INSTRUCTIONS FOR TOSHIBA LCD MODULES".
Refer to individual specifications and TECHNICAL DATA sheets (hereinafter called "TD") for more detailed technical
information.
1) SPECIAL PURPOSES
A) Toshiba Matsushita Display Technology's Standard LCD Modules have not been customized for operation in extreme
environments or for use in applications where performance failures could be life-threatening or otherwise catastrophic.
B) Since Toshiba Matsushita Display Technology's Standard LCD Modules have not been designed for operation in extreme
environments, they must never be used in devices that will be exposed to abnormally high levels of vibration or shock which
exceed Toshiba Matsushita Display Technology's published specification limits.
C) In addition, since Toshiba Matsushita Display Technology Standard LCD Modules have not been designed for use in
applications where performance failures could be life-threatening or catastrophic, they must never be installed in aircraft
navigation control systems (such as, but not limited to Traffic Collision Avoidance System and Air Traffic Indicator), in military
defense or weapons systems, in critical industrial process-control systems (e.g., those involved in the production of nuclear
energy), or in critical medical device or patient life-support systems.
2) DISASSEMBLING OR MODIFICATION
DO NOT DISASSEMBLE OR MODIFY the module. It may damage sensitive parts inside LCD module, and may cause
scratches or dust on the display.
Toshiba Matsushita Display Technology doses not warrant the module, if customer disassembled or modified it.
3) BREAKAGE OF LCD PANEL
DO NOT INGEST liq uid cryst al material, DO NOT I NHALE this material, and DO NOT CONTACT the material with skin, if LCD
panel is broken and liquid crystal material spills out.
If liquid crystal material comes into mouth or eyes, rinse mouth or eyes out with water immediately.
If this material contact with skin or cloths, wash it off immediately with alcohol and rinse thoroughly with water.
4) GLASS OF LCD PANEL
BE CAREFUL WITH CHIPS OF GLASS that may cause injuring fingers or skin, when the glass is broken.
5) ELECTRIC SHOCK
DISCONNECT POWER SUPPLY before handling LCD module.
DO NOT TOUCH the parts inside LCD module and the fluorescent lamp's connector or cables in order to prevent electric
shock, because high voltage is supplied to these parts from the inverter unit while power supply is turned on.
6) ABSOLUTE MAXIMUM RATINGS AND POWER PROTECTION CIRCUIT
DO NOT EXCEED the absolute maximum rating values under the worst probable conditions caused by the supply voltage
variation, input voltage variation, variation in parts' const ants, environment al temperature, etc., otherwise LCD module may be
damaged.
Employ protection circuit for power supply, whenever the specification or TD specifies it.
Suitable protection circuit should be applied for each system design.
7) RECOMMENDED OPERATION CONDITIONS
The performance and quality of the LCD panel are warranted only when the LCD panel is used within “the recommended
operation conditions”. Toshiba Matsushita Display Technology Co., Ltd. never warrants the performance and quality of the
LCD panel when you use the LCD panel over “the recommended operatio n conditions”, although within “the absolute
maximum rating”.
To use the LCD panel over “the recommended operation conditions” may have bad influence on the characteristics and
reliability of the LCD panel and may shorten the life of the LCD panel.
Therefore, when designing the whole set, not to be over “the recommended operation conditions”, you should fully t ake care of
supply voltage change, characteristic of connection parts, serge of input-and-output line, and surrounding temperature.
8) DISPOSAL
When dispose LCD module, obey to the applicable environmental regulations.
