Richer Colors at Wider Angles - Like many tablets, Kindle Fire HD uses In-Plane Switching (IPS) to improve color reproduction. But displays that only use IPS still appear washed out at various angles, such as laid sideways when reading in bed, laid flat on a table, or held between you and a friend when sharing a movie. Kindle Fire HD addresses this issue by applying an advanced polarizing filter directly to the LCD panel. This results in a display that shows the same deep contrast and rich, detailed color when viewed at any angle.
