FAQ
Question: Running python program there is ImportError: No module named Image?
Answer: Install the imaging library using the command sudo apt-get install python-imaging.
Question: After multiple positions are brushed, the font is lighter after refreshing several times?
Answer: In this case, the customer needs to reduce the position of the round brush and clear the screen after 5 rounds of refreshing (increasing the voltage of VCOM can improve the color, but it will increase the afterimage).
Question: When the ink screen is in deep sleep mode, the first time the screen refreshes will be unclean. How can I solve it?
Answer: The process of re-awakening the e-ink screen is actually the process of re-powering on the power. Therefore, when the EPD wakes up, it must first clear the screen, so as to avoid the afterimage phenomenon to the greatest extent.
