Turns out the secret to the new Nook’s patent pending magic glow isn’t so magic after all. Nope, it utilizes the wonder of diffraction. Yep, the driving force behind this marriage-saving device is science! Says iFixit in its latest teardown,
The display assembly contains the front glass, digitizer, and array of GlowLight LEDs, all fused together into one component. The glass over the E-ink screen takes the light from the eight LEDs and evenly distributes it across the screen.
How did the site discover the pending patentness after peeling back the e-reader’s layers? Why, lasers, of course, beaming one through the aforementioned glass, which diffracted the green light before it hit a wall, proving once and for all that science can be fun. And ripping gadgets apart, naturally.
