1. GENERAL FEATURES
Display Elektronik GmbH is specialized in LCD-products.
- There is a wide range of standard lcd-panels. Most of them are available from stock.
- Most of our standard panels operate within the extended temperature range (–20°C to +70°C).
- For the static types the Vlcd is ready for 3 Volt, like shown in the following table. For most of our
multiplexed standard panels we offer a 3Volt and a 5Volt model.
- Most panels are available in reflective and transflective version.
- In general we offer a standard pinlength from stock. Pls ask us in case you want a different pinlength.
For the LCD-panels without pins we also offer elastomeric connectors (zebras).
- For outdoor applications we offer suitable LCD-displays with extreme wide temperature range and
UV-stability etc...

9. CONNECTING LCDs
- Fixed pins have a typical pitch of 2,54mm. (Pls refer to mechanical specification).
- LCD for elastomeric connectors (zebras) may have thighter pitches. Please regard tolerances and pitch
of elastomer connector.

11. CLEANING OF LCDs
- LCDs have a protective foil on top of the front glass. This foil should be removed at the latest possible
stage.
- If there is a need of cleaning, you may use freon or alcohol with a soft fabric, as front polarizers are
sensitive to physical damage.
- Pls also note this protective foil on the rear side, in case you use transflective model-types.
- Do not use ultrasonic for cleaning of PCB once LCD is soldered.
12. HANDLING PRECAUTIONS
- As polarizers of LCD (front and rear-side) are sensitive, they must be handled with care.
- DC Voltage or drive voltage higher than specified voltage will decrease the lifetime of the liquid
crystal display panel.
- If any fluid leaks out of a damaged glass cell, wash off any human part that comes into contact with
soap and water. Never swallow the fluid. The toxicity is low, but caution should exercised at all times.
- LCD is made up of glass, organic sealant, organic fluid and polymer based polarizers. The following
precautions should be taken when handling:
Keep the temperature within range for use and storage. Excessive temperature and humidity could
cause polarization degredation, polarizer peel-off or bubble generation. When storage for a long
period over 40°C is required, the relative humidity should be kept below 60%.
