One of the big innovations in the e-reader industry was the advent of built in lightning called “frontlight.” The Barnes and Noble Nook with Glowlight was the first model to include this technology in late 2013 and the rest of the industry embraced it quickly. With all of the different e-readers on the market how do you know your model has a really good light system? We have been extensively documenting it for many years on our YouTube channel but Pocketbook has taken a scientific approach.
Pocketbook has just released a new technical document that takes a look at high frequency ripples throughout the entire brightness range. To be honest, I have never seen so many e-readers documented at once and look at things like the Ripple frequency or Ripple coefficient.
The e-readers Pocketbook evaluates in this test include the Tolino Vision 2, Kobo Aura H2O, Kobo Aura, Kindle Voyage, Cybook Odyssey HD, and the Pocketbook Sense.
