(This article is an English translation of my original work, written on July 25, 2021. Here is the original script ) The speed and display differences between E Ink devices and LCD backlit tablets are frequently discussed.

Therefore, you probably have some understanding of the differences between various E Ink technologies and the E Ink devices from different brands. The common points of hesitation for most people before buying an E Ink device boil down to the following: Is it better to choose a dedicated e-reader or a multi-functional E Ink tablet? Which brand of E Ink device is better? Which size of E Ink device is better? Is it better to choose color or black and white?
