Samsung Electronics has begun US shipments of its new line of Slim Depth LED Engine Widescreen DLP? HDTVs, which feature PhlatLight™ LED technology from Luminus.

The six new models use Luminus’ high-powered, energy-efficient LED illumination in place of a UHP or arc lamp, the traditional light source found in most projection TVs.

Samsung’s new LED-based Slim DLP HDTVs with 1080p resolution are on store shelves at national US retailers including, Best Buy, Circuit City, Sears, and Tweeter.

Last year, Samsung introduced the first LED DLP, the HL-S5679W, and the six new models in this year's product line are available in three large screen sizes: 50-, 56- and 61-inch. Prices start at $2500.

The new models are illuminated using a single PhlatLight PT120 chipset, which was specifically designed and optimized for use with the TI's xHD5 1080p DLP chipset. The PT120’s red, green and blue LEDs combine to produce pure, accurate sequential colored light and cycle at 2.9 kHz, 48 times faster than traditional television frame rates, creating a smooth, stable color and superior motion quality.

Luminus says that the PhlatLight PT120 chipset is currently in full-scale production at the company's own state-of-the-art semiconductor fab just outside of Boston, Massachusetts.
