Philips Ambilight technology creates a colored aura that extends the viewing experience beyon the edges of the screen. This unique backlight effect automatically changes to match the colors and intensity of the picture. The immersive effect enhances the TV image, engages your peripheral vision, reduces eyestrain, helps you unwind - and makes your home look amazing. By projection this aura around the whole TV, it creates the most stunning “floating” effect. The science behind Ambilight revolves around the way the human eye works. Your eyes can become fatigued over time in response to a single-light source such as a TV in a dimmed room. Backlight the television correctly, without glare, relaxes the eyes.
