Again an eInk panel is not going to be backlit. Take that lightsource you use with a non-illuminated ereader. Hold it behind the ereader. Not bloody much use, is it? eInk needs a light source in front of the screen as the displayu is opaque. LEDs at the edge of the screen and a rather complex lightguide supply that light source. Take a look at Wikipedia's entry for E_Ink and check out the layout of the capsules. A light shining from the back would pass through both the white and black particles.

Perhaps nitpicking but such inaccuracy should be corrected much like correcting a Flat Earther must be done. It may be a waste of breath but the attempt has to be made.
