What Screen Type and How Big?īasic ebook readers use monochrome e-ink screens to display text. Amazon's Kindles dominate the ebook reader market in the US, but if you're shopping around, it's a good idea to look at models from Kobo, Nook, Onyx and PocketBook. They have very long battery life and look terrific in sunlight. Ebook readers, also called ereaders, rely on e-ink screens to let you read for long periods of time without the brain-burn that comes from a radiant LCD or OLED screen. Step away from the monitor and give your eyes a rest. Best Hosted Endpoint Protection and Security Software.
