Philips has added two new models in its LED TV series, the 40PFL9704 and the 46PFL9704. These TVs come with Philips’ next generation LED backlight technology which promise a better contrast ratio, faster refresh rate and more power efficient than the standard LCD TVs. They will be launched in December for the U.K.'s market.
