"<p><a href=\"https://ledstrain.org/d/1547/1\" class=\"PostMention\" data-id=\"20108\" rel=\"\" target=\"\">daniels</a>  Is there a backlight in your Kindle...I know some of them did, and it looks all new ones do?</p>\n\n<p>On my Kindle Paperwhite (e-ink with backlight) , even on the \"lowest\" brightness level, there is a very dim backlight, that I can only really see in a pitch black room. I suspect it uses PWM.</p>\n\n<p>If there is no backlight, the display should in theory be static. Changing the font might be worth a try, I believe they changed it.</p>\n\n<p>I will have trouble reading print after exposure to a bad display. It's worth ruling out that you didn't see a bad device and the symptoms still remained using the Kindle.</p>"
