LCM displays full white. The brightness is the average value of 9 measured spots. Measurement equipment PR-705 (Φ8mm) Measuring condition: - Measuring surroundings: Dark room. - Measuring temperature: Ta=25°C. - Adjust operating voltage to get optimum contrast at the center of the display. Measured value at the center point of LCD panel after more than 5 minutes while backlight turning on. Note 2: The luminance uniformity is calculated by using following formula. ∆Bp = Bp (Min.) / Bp (Max.)×100 (%) Bp (Max.) = Maximum brightness in 9 measured spots Bp (Min.) = Minimum brightness in 9 measured spots.

(Test LCD using DMS501): The output signals of photo detector are measured when the input signals are changed from “black” to “white” (falling time) and from “white” to “black” (rising time), respectively. The response time is defined as the time interval between the 10% and 90% of amplitudes. Refer to figure as below.

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 there is some variance between models. drivers. Note that • 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 as they may seep under the elastomeric connection and cause display failure. • 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 12
