2. Application information for DID (Digital Information Display)
A long-term display like DID application may cause uneven display including image retention.
To optimize module's lifetime and function, several operating usages are required.
1. Normal operating condition
a. Temperature: 20 15
b. Humidity: 55 20 %
c. Display pattern: moving picture or regular switchover display
Note) Long-term static information image may cause uneven display.
2. Operating usages under abnormal operating condition. Note (1)
a. Ambient condition
- Well-ventilated place is recommended to set up DID system.
b. Power off and screen saver
- Periodical power-off or screen saver is needed after long-term static display. Note (2)
3. Operating usages to protect uneven display due to long-term static information display
a. Suitable operating time for P-DID : under 20 hours a day.
b. Periodical display contents change from static image to moving picture.
- Liquid crystal refresh time is required.
c. Periodical background color and character (image) color change
- Use different colors for background and character (image), respectively.
- Change colors periodically.
d. Avoid combination of background and character with large different luminance.
Note (1) Abnormal condition means every operating condition except normal operating condition.
Note (2) Moving picture or black pattern is strongly recommended for screen saver.
4. Lifetime in this spec is guaranteed only when DID is used under right operating usages.
