LPhlatLight RGB Chipset for Microdisplay TVs

Woburn, MA, USA, based Luminus Devices, Inc., announced that its PhlatLight PT120 chipset is being sampled to its microdisplay projection television customers. The red, green and blue LEDs in the PT120 chipset combine to produce more than 1,500 white lumens under normal operating conditions, enough brightness to illuminate RPTVs up to 62 inches with a single RGB chipset.
While the PT120 chipset is suitable for any microdisplay smaller than 0.7 inches, it was specifically optimized for use with the Texas Instruments xHD5 1080p DLP® technology chipset. The size and shape of the PT120 allow users to maximize the amount of light that can be collected and projected onto the screen.
“Luminus is leading the way in advancing LED technology to new levels of performance. This new chipset is testament to their commitment of offering innovative lighting solutions for large screen microdisplay products,” said Adam Kunzman, business manager for DLP HDTV products at Texas Instruments. “Through our joint collaboration, we look forward to providing our mutual customers with a competitive advantage in the rapidly growing big-screen HDTV market.”
The PhlatLight PT120 is a three-colour system that includes a red, green and blue LED. Each LED is a single, large area monolithic chip that can sustain extremely high power and fast pulsing.
“Because PhlatLight LEDs are a solid state light source, the colors can be cycled at high rates,” said Christian Hoepfner, vice president of products at Luminus Devices. “In a DLP HDTV system the red, green and blue PhlatLight LEDs can cycle at 2.9 KHz, which is 48 times faster than traditional television frame rates, providing superior motion quality.”
Another benefit of PhlatLight technology is its longer lifetime. In addition to providing superior colour and image quality, PhlatLight LEDs have significantly longer lifetimes than arc lamps. With a lifetime that exceeds 60,000 hours, PhlatLight chipsets will never have to be replaced.
The PhlatLight PT120 chipset is currently being designed into a number of DLP HDTVs that use the xHD5 DLP chip, with screen sizes as large as 62 inches. Several models from various manufacturers will be commercially available in 2007.
Luminus Devices, Inc. also announced receipt of six major U.S. patents for its PhlatLight technology. Luminus has filed over 100 additional U.S. and international patent applications, many of which have been allowed and are expected to be issued later this year.
