Just a swish and a flick of the spudger and the lone ribbon cable surrounding the whole assembly is freed.

The cable's adhesive also secures the backlight guide, allowing the LEDs to shine on, providing backlighting for the e-paper screen.

We learned in our Nook Simple Touch with GlowLight teardown that light guides work by bouncing light shined in one end through a diffraction grating to provide an even glow—in this case beneath the e-paper display.
