FAQ

Question:
Working requirements of e-Paper?
Answer:
  • 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.


Question:
What do you need to note about e-Paper refreshing?
Answer:
  • 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.


Question:
How much could the flexible e-paper be bended
Answer:
  • The IC part of e-Paper cannot be bended, you can bend the display area in degree larger than 60°C


Question:
Why the e-Paper cant work with Arduino?
Answer:

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.


Question:
Why does the color of e-Paper look a little black or grey?
Answer:

You can try to change the value of Vcom on demo codes.


Question:
Three-color e-paper looks more red/yellow than the picture on website?
Answer:

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.


Question:
Why my e-paper has ghosting problem after working for some days
Answer:

Please set the e-paper to sleep mode or disconnect it if you needn't refresh the e-paper but need to power on your development board or Raspberry Pi for long time.Otherwise, the voltage of panel keeps high and it will damage the panel



Question:
Why the FPC of the e-Paper is broken after using for some times?
Answer:
Please make sure you have used it in correct way.
