- Two-color B/W e-paper
- 【Working】Temperature: 0~50°C; Humidity: 35%~65%RH
- 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 6 months
- 【Transport】Temperature: -25~70°C; Max transport time: 10 days
- 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h
- Three-Color e-Paper
- 【Working】Temperature: 0~40°C; Humidity: 35%~65%RH
- 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 3 months
- 【Transport】Temperature: -25~60°C; Max transport time: 10 days
- 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h
When store three-color e-Paper, please refresh it to white, and keep the screen upward. Note that you need to update it at least every three months.
- Refresh mode
- Full refresh: e-Paper flicker when full refreshing to remove ghost image for best display.
- Partial refresh: It don't flicker if you use partial refresh (only some of the two-color e-paper support partial refresh). Note that you cannot use Partial refresh all the time, you should full refresh e-paper regularly, otherwise, ghost problem will get worse even damage.
- Refresh rate
- When using, you should set the update interval at least 180s.(except Partial supportable types)
- Please set the e-Paper to sleep mode or power off it directly, otherwise, the e-Paper is damaged because of working in high voltage for long time.
- You need to update the content of three-color e-Paper at least one time every 24h to avoid from burn-in problem.
- Working place
- We recommend you to use the e-Paper indoor. If you need to set the e-paper outdoor, Please place the e-paper in shadow and protect it from UV. When you designed you e-paper product, you should take care about the working situation like temperature, humidity, etc.
- The IC part of e-Paper cannot be bended, you can bend the display area in degree larger than 60°C
The I/O level of Arduino is 5V, and the e-Paper should be driven with 3V3. If your Arduino cant drive the e-Paper successfully, please try to convert the level to 3.3V
You can also try to connect the Vcc pin to the 5V of Arduino to see whether the e-Paper works, but we recommend you not to use 5V for a long time.
You can try to change the value of Vcom on demo codes.
Because of different batch, some of them have aberration. Store the e-Paper right side up will reduce it. And if the e-Paper didn't be refreshed for long time, it will become more and more red/yellow. Please use the demo code to refresh the e-paper for several times in this case.
