Question about PocketBook Color

It is correct that the PocketBook Pro Color Lux was first on the market (2013), but the market success here was not particularly good. Colour e-book readers work with a combination of a black-and-white and a colour panel. Until now, the colour panel has always been made of glass and, due to its poor reflective behaviour, required active lighting to provide a qualitatively acceptable display at all. The result was a spongy, blurred display that was no pleasure to read.

The PocketBook Color didn't come out until 2020 and the new technology Kaleido, which came out in 2019, means this e-reader can do without the extra glass display. This makes e-readers lighter and easier to read due to the higher contrasts. In addition, the display consumes less energy. Accordingly, the colour display on the new e-reader has become very good in terms of quality and is no longer a comparison with the old model.
