As I understand from your explanation the only possible way to add more colours could be overlap eInk layers, making them thiner. If this is it we will end having monochrome ereaders to read and thick big display ereaders to work/watch videos, etc

eInk is opaque so you can't add layers and current eInk displays are limited to 16 levels (white, 14 greys and black). Going by the pre-release specs for the Pocketbook 6" colour eInk reader, it has 100 PPI in colour and 300 PPI in greyscale using the eInk Kaleido display.

Go back to the first sentence of my reply. The reason that eInk displays use a front light is that the display is opaque. A back light will
not work. Take a look at the image attached for an idea of the structure of an eInk EPD capsule.

LiquaVista, Mirasol, etc. have come and gone. ClearInk is a moving target -- "we'll be in production next year".
