Protect Yourself from Blue Light with Digital Color Filters

Amazon Kindles don’t have backlights, they use E Ink, a reflective, not emissive display (LCDs and OLEDs are emissive). The Kindle Paperwhites and other models with LEDs have them arranged around the edges, casting light onto the E Ink so it’s visible in the dark. They use “white” LEDs that include blue wavelengths but you can turn down their brightness or turn them off and read with whatever light you want.

Yes, you’re correct. It’s not a backlight so much as sidelights. I don’t have the latest Kindle, but knowing that you can adjust the color temperature might tempt me to buy one the next time it’s on sale.
