Handling & Storage
PRECAUTIONS FOR HANDLING & STORAGE OF OLED DEVICES
Handling
ATTENTION
ELECTROSTATIC
SENSITIVE DEVICES
1. The IS Series OLED devices are electrostatic sensitive. To avoid damage to IC,
do not touch terminals unless properly isolated from static electricity.
2. Signal input under conditions not recommended may cause damage to the OLED unit or deterioration of the
display. Follow directions regarding supply sequences of power and signal voltages.
3. If the OLED panel is broken, avoid touching the contents. Wash off any contact to the skin or clothing.
4. Limit operating force to switch keytop to 100.0N maximum, as excessive pressure may damage the OLED.
5. Recommended soldering time and temperature limits for OLED switch:
Avoid temperatures exceeding 80°C at the OLED.
Wave Soldering: see Profile A in Supplement section.
Manual Soldering: see Profile A in Supplement section.
6. The IS series OLED devices are not process sealed.
7. Pixels acquire diminished brightness over time and use, and those most frequently habituated have greater reduction of brightness than those less used. To minimize this difference, operate OLED unit so that all pixels are used as consistently as possible.
8. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry with clean cloth. Do not use organic solvent.
9. Proper serial resistors and buffers for signals should be used to prevent noise problems.
Storage
1. Store in original container and away from direct sunlight.
2. Keep away from static electricity.
3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
