Contrast ratio is defined as follows.
CR = LOFF / LON
LON : Luminance of the ON segments, LOFF : Luminance of the OFF segments
The time that the luminance level reaches 90% of the saturation level from 0% when ON signal is applied.
The time that the luminance level reaches 10% of the saturation level from 100% when OFF signal is
applied.
Definition of Driving Voltage VD. Assuming that the typical driving waveforms shown below are applied
to the LCD Panel at /A Duty - 1/B Bias ( A : Duty Number, B : Bias Number ). Driving voltage VD is
defined s follows: VD = (Vth1+Vth2) / 2
Vth1 :
The voltage VO-P that should provide 50% of the saturation 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 saturation level in the luminance at the
segment which the OFF signal is applied to.

Handling and Precautions
The Following precautions will guide you in handling our product correctly.
1
Liquid crystal display devices
1.1
1.2
2
Care of the liquid crystal display module against static electricity discharge.
2.1
2.2
2.3
3
When working with the module, be sure to ground your body and any electrical equipment you may be using. We
strongly recommend the use of anti static mats ( made of rubber ), to protect work tables against the hazards of
electrical shock.
Avoid the use of work clothing made of synthetic fibers. We recommend cotton clothing or other
conductivity-treated fibers.
Slowly and carefully remove the protective film from the LCD module, since this operation can generate static
electricity.
When the LCD module alone must be stored for long periods of time:
3.1
3.2
3.3
4
The liquid crystal display device panel used in the liquid crystal display module is made of plate glass. Avoid any
strong mechanical shock. Should the glass break handle it with care.
The polarizer adhering to the surface of the LCD is made of a soft material. Guard against scratching it.
Protect the modules from high temperature and humidity.
Keep the modules out of direct sunlight or direct exposure to ultra-violet rays.
Protect the modules from excessive external forces.
Use the module with a power supply that is equipped with an over current protector circuit, since the module is not
provided with this protective feature.

Do not ingest the LCD fluid itself should it leak out of a damaged LCD module. Should hands or clothing come in
contact with LCD fluid, wash immediately with soap.

Conductivity is not guaranteed for models that use metal holders where solder connections between the metal holder and
the PCB are not used. Please contact us to discuss appropriate ways to assure conductivity.

Warranty
This product has been manufactured to your company’s specifications as a part for use in your company’s general electronic
products. It is guaranteed to perform according to delivery specifications. For any other use apart from general electronic
equipment, we cannot take responsibility if the product is used in medical devices, nuclear power control equipment, aerospace
equipment, fire and security systems, or any other applications in which there is a direct risk to human life and where
extremely high levels of reliability are required. If the product is to be used in any of the above applications, we will need to
enter into a separate product liability agreement.
1
We cannot accept responsibility for any defect, which may arise from additional manufacturing of the product
(including disassembly and reassembly), after product delivery.
2
We cannot accept responsibility for any defect, which may arise after the application of strong external force to the
product.
3
We cannot accept responsibility for any defect, which may arise due to the application of static electricity after the
product has passed your company’s acceptance inspection procedures.
4
We cannot accept responsibility for industrial property, which may arise through the use of your product, with
exception to those issues relating directly to the structure or method of manufacturing of our product.
