REVISIONS REV. - DESCRIPTION RELEASED ON ECN #E0750 DATE APPROVED 7/28/98 MA Specification subject to change without notice. All dimensions and specifications apply to standard modules. This information may vary for modules with optional features. All dimensions are in millimeters. Precautions:These precautions apply equally to modules from all makers, not just Densitron. Violation of these guidelines may void the warranty and can cause problems ranging from erratic operation to catastrophic display failure. 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 VDD and VSS, however briefly. Use a clean power source free from transients. Power up conditions are occasionally "jolting" and may exceed the maximum ratings of the module. The +5V power of the module should also supply the power to all devices which may access the display. Don't allow the data bus to be driven when the logic supply to the module is turned off. DO NOT install a capacitor between the VO (contrast) pin and ground. VDD must, at all times, exceed the VO voltage level. The capacitor combines with the contrast potentiometer to form an R-C network which "holds-up" VO, at power-down, possibly damaging the module. 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. (Recommended max. length 30 cm). For models with EL or CCFL backlights, do not disable the backlight by interrupting the HV line. Unloaded inverters produce voltage extremes which may arc within a cable or at the display. 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. Densitron recommends the use of Kester "245" no-clean solder. Mount the module so that it is free from torque and mechanical stress. Surface of 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.
