==== LED-based DLPs ====
The first commercially available LED-based DLP HDTV was the [[Samsung]] HL-S5679W in 2006, which also eliminated the use of a color wheel. Besides long lifetime eliminating the need for lamp replacement and elimination of the color wheel, other advantages of LED illumination include instant-on operation and improved color, with increased color saturation and improved color gamut to over 140% of the [[RGB color space|NTSC color gamut]]. Samsung expanded the LED model line-up in 2007 with products available in 50-, 56- and 61-inch screen sizes. In 2008, the third generation of Samsung LED DLP products were available in 61- (HL61A750) and 67-inch (HL67A750) screen sizes.

Ordinary LED technology does not produce the intensity and high-lumen output characteristics required to replace arc lamps. The special LEDs used in all of the Samsung DLP TVs are [[PhlatLight]] LEDs, designed and manufactured by US-based [[Luminus Devices]]. A single RGB PhlatLight LED chipset illuminates these projection TVs. The PhlatLight LEDs are also used in a new class of ultra-compact DLP front projector commonly referred to as a "pocket projector" and have been introduced in new models from LG Electronics (HS101), Samsung (SP-P400) and [[Casio]] (XJ-A series). Home theater projectors will be the next category of DLP projectors that will use PhlatLight LED technology. At InfoComm in June 2008, Luminus and TI announced their collaboration on using their technology on home theater and business projectors and demonstrated a prototype PhlatLight LED-based DLP home theater front projector. They also announced products will be available in the marketplace later in 2008 from [[Optoma Corporation|Optoma]] and other companies to be named later in the year.

Luminus Devices PhlatLight LEDs were also used by [[Christie (audiovisual company)|Christie Digital]] in their DLP-based [[MicroTiles]] display system.<ref>{{cite press release| url = http://www.businesswire.com/portal/site/home/permalink/?ndmViewId=news_view&newsId=20100609006222&newsLang=en |archive-url=https://web.archive.org/web/20120919143312/https://www.businesswire.com/portal/site/home/permalink/?ndmViewId=news_view&newsId=20100609006222&newsLang=en |archive-date= 2012-09-19 |title=Luminus Devices' PhlatLight LEDs Illuminate Christie MicroTile's New Digital Canvas Display |via=Businesswire |date=June 9, 2010}}</ref> It is a modular system built from small (20&nbsp;inch diagonal) rear projection cubes, which can be stacked and tiled together to form large display canvasses with very small seams. The scale and shape of the display can have any size, only constrained by practical limits.
