The display assembly contains the front glass and array of GlowLight LEDs, all fused together into one component.

Notice the array of eight LEDs located on top of the display assembly. These LEDs are the only light for the entire screen.

The glass over the E-ink screen takes the light from the eight LEDs and evenly distributes it across the screen.

How, you ask?

The glass is specially designed using a fundamental principle of optics: diffraction.
