signal is applied.
Note 4 : Definition of Driving Voltage VD
Assuming that the typical driving waveforms shown below are applied to the LCD Panel at
1/A Duty - 1/B Bias ( A : Duty Number, B : Bias Number ). Driving voltage VD is definded
as follows.
VD = (Vth1+Vth2) / 2
Vth1 : The voltage VO-P that should provide 50% of the satulation level in the luminance at
the segment which the ON signal is applied to.
Vth2 : The voltage VO-P that should provide 50% of the satulation level in the luminance at
the segment which the OFF signal is applied to.

10.Handling Precautions
Operex Products are designed for use in ordinary electronic devices such as business machines,
telecommunications equipment, measurement devices and etc..
Optrex Products are not designed, intended, or authorized for use in any application in which the
failure of the product could result in a situation where personal injury or death may occur. These
applications include, but are not limited to, life-sustaining equipment, nuclear control devices,
aerospace equipment, devices related to hazardous or flammable materials, etc. (If Buyer intends to
purchase or use the Optrex Products for such unintended or unauthorized applications, Buyer must
secure prior written consent to such use by a responsible officer of Optrex Corporation.) Should Buyer
purchase or use Optrex Products for any such unintended or unauthorized application (without such
consent), Buyer shall indemnify and hold Optrex and its officers, emplo yees, subsidiaries, affiliates
and distributors harmless against all claims, costs, damages and expenses, and reasonable attorney's
fees, arising out of, directly or indirectly, any claim of personal injury or death associated with such
unintended or unauthorized use, even if such claim alleges that Optrex was negligent regarding the
design or manufactur e of the pa rt.
1) LCD may be broken because it is made of glass.
2) Polarizer is a soft material and can easily be scratched.
3) Please avoid static electricity.
① Please be sure to ground human body and electric appliances during work.
② It is preferable to use conductive mat on table and wear cotton clothes or conduction processed
fiber. Synthetic fiber i s not recommended.
③ P lease slowly peel off protective film, because static electricity may be charged.
4) If it is necessary to store LCD mod ules for a long time, please comply with the following
procedures. If storage condition is not satisfactory, display (especially polarizer) may be
deteriorated o r so ldering I/O terminals may b ecome difficult (some oxide is generated at I/O
terminals plating).
① Store as delivered by Optrex
② If you store as unpacked, put in anti-static bag, seal its opening and store where it is not subjected
to direct sunshine nor fluorescent lamp.
③ Store at temperature 0 to +35℃ and at low humidity. Please refer to our specification sheets for
storage temperature range and humid ity condition.
5) The module does not contain excess current limiter.
Please design the limiter to cut excess current in your power supply circuit.
6) The connection between the bezel and VSS (GND) is not specified in the module.
(Some module do not maintain connection between them.)
Please consult OPTREX to specify the connection.
7) Liquid crystal may be leaked when display is broken. Never taste it. If your hands or clothes touch
it, please immediately wash using soap.
Optrex shall not be responsible for any infringement of industrial property rights of third parties in any
country arising out of the application or use of Optrex Products, except which directly concern the
structure or production of such products.
