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.

10.Handling Precautions

Optrex 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 regardi ng t he design or manufacture of the par t .

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 is not recommended.

③ Please 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 or soldering

I/O terminals may become 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

dir ect 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 humidity condition.

5) The module does not contain excess current limiter.

Please design the limiter to cut excess current in your power supply circuit.

6) 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.
