*Frontlight. Backlight is not possible in eink readers, right?

  My Kobo has an adjustable backlight that works great.

    Are you sure it’s a backlight? I’m looking at my Libra 2 and can’t tell whether the light’s in front or in back.

      Maybe its back but conducted to front through a piece of translucent plastic? I.e. still a frontlight.

      I can say perceptually it's a backlight, how they did it in engineering terms I'm not sure. It can even be in dark mode and variably backlight only the foreground content with no change in the illumination of the dark background.

    Little dated (2012) but basic material properties of eink has not changed: https://archive.nytimes.com/www.nytimes.com/interactive/2012/12/26/technology/light-reading.html https://archive.nytimes.com/www.nytimes.com/interactive/2012... Eink due to its USP and fundamental characteristics only reflects light and does not transmit (i.e., is not transparent. Transparency is needed for back lighting).
