Specification subject change without notice. dimensions specifications apply standard modules. This information vary modules with optional features. dimensions millimeters. Precautions:These precautions apply equally modules from makers, just Densitron. Violation these guidelines void warranty cause problems ranging from erratic operation catastrophic display failure.
Handling precautions: This device susceptible Electro-Static Discharge (ESD) damage. Observe Anti-Static precautions. Power supply precautions: Identify and, times, observe absolute maximum ratings both logic drivers. Note that there some variance between models. Prevent application reverse polarity VSS, however briefly. clean power source free from transients. Power conditions occasionally "jolting" exceed maximum ratings module. power module should also supply power devices which access display. Don't allow data driven when logic supply module turned off. install capacitor between (contrast) ground. must, times, exceed voltage level. capacitor combines with contrast potentiometer form network which "holds-up" powerdown, possibly damaging module. Operating precautions: plug unplug module when system powered Minimize cable length between module host MPU. (Recommended max. length cm). models with CCFL backlights, disable backlight interrupting line. Unloaded inverters produce voltage extremes which within cable display. Operate module within limits modules temperature specifications. Mechanical Environmental precautions: Improper soldering major cause module difficulty. flux cleaner recommended they seep under elastomeric connection cause display failure. Densitron recommends Kester "245" no-clean solder. Mount module that free from torque mechanical stress. Surface panel should touched scratched. display front surface easily scratched, plastic polarizer. Avoid contact clean only when necessary with soft, absorbent cotton dampened with petroleum benzene. ALWAYS employ anti-static procedure while handling module. Prevent moisture build-up upon module observe environmental constraints storage temperature humidity. store direct sunlight. leakage liquid crystal material should occur, avoid contact with this material, particularly ingestion. body clothing becomes contaminated liquid crystal material, wash thoroughly with water soap.
