12. Safety Precaution

Handling precautions:

•

This device is susceptible to Electro-Static Discharge (ESD) damage. Observe Anti-Static precautions.

Power supply precautions:

•

Identify and, at all times, observe absolute maximum ratings for both logic and LC

drivers. Note that

there is some variance between models.

•

Prevent the application of reverse polarity to VCC and GND, however briefly.

•

Use a clean power source free from transients. Power up conditions are occasionally “jolting” and may

exceed the maximum ratings of the modules.

•

The VCC power of the module should also supply the power to all devices that may access the display.

Don’t allow the data bus to be driven when the logic supply to the module is turned off.

Operating precautions:

•

DO NOT plug or unplug the module when the system is powered up.

•

Minimize the cable length between the module and host MPU.

•

Operate the module within the limits of the modules temperature specifications.

Mechanical/Environmental precautions:

•

Improper soldering is the major cause of module difficulty. Use of flux cleaner is not recommended.

•

Mount the module so that it is free from torque and mechanical stress.

•

Surface of the LCD panel should not be touched or scratched. The display front surface is an easily

scratched, plastic polarizer. Avoid contact and clean only when necessary with soft, absorbent cotton

dampened with petroleum benzene.

•

Always employ anti-static procedure while handling the module.

•

Prevent moisture build-up upon the module and observe the environmental constraints for storage

temperature and humidity.

•

Do not store in direct sunlight

•

If leakage of the liquid crystal material should occur, avoid contact with this material, particularly

ingestion. If the body or clothing becomes contaminated by the liquid crystal material, wash thoroughly

with water and soap
