I'd always thought that back-lighting required a transmissive display (i.e. one that relied on light passing through it to generate the image), and that e-ink was a reflective display, i.e. that light was reflected from it. Whilst being a reflective display doesn't preclude lighting, I'd assumed that it would not then be a back-lit, but instead a front-lit display (e.g. as the Sony accessory does). Or have I misunderstood something (decidedly possible!)?
