FAQ

Three-color e-paper looks more red than the picture?

Because of different batch, some of them have aberration. Store the e-Paper right side up will reduce it. And if the e-Paper didnt 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.
