It's 4 Channel LED: RGB +(B/G boost). This implementation is supposed to be brighter with better contrast than traditional RGB LED according to the product page:

Unfortunately its 0.47" (XPR), which is why the price is so low...

Both the HU70LA and the HU85LA are both wheel-less single chip DLP projectors. I am extremely sensitive to RBEs and that's why I'm looking a this projector. The HU70LA uses 4 channel LEDs which is why it can achieve 95% of the DCI P3 color space with no RBEs, wider color gamut than Laser. From the LG press release:
"The HU70LA employs an innovative 4-channel LED lighting system and wheel-less technology, to deliver a stunning viewing experience with impeccable color accuracy. LG's wheel-less technology enables each model to produce an expanded color gamut with greater accuracy than traditional Digital Light Processing (DLP) projectors that use color wheels and works to eliminate distracting visual effects such as the rainbow effect, clouding and color distortion. The HU85LA also employs a wheel-less system but uses a 3-channel laser as the light source."
this should theoretically result in more sharpness and contrast from the smaller
0.47" DMD as there is no alignment issues as with 3 chip LCD, no color bleed or haze associated with color wheels and phosphors.
Good example of this is the BENQ HT9060... it is a 0,66" DMD which is not native 4K, but when compared to the native Sony 695ES, it can actually be sharper in resolving 4K content because of a better lens and lack of colorbleed /misalignment associated with 3xLCD chips. Check out this comparison by TVS Pro and see what I mean:
A wheel-less single chip DLP could be even sharper, though only the 85LA has the 0.66" DMD
. wish they'd used that DMD for the 70LA instead of the 0.47", I'd pay the premium for the sharpness and better contrast. Still, the JVC LX-UH1B uses the 0.47" DMD for home theater projector and it gets decent brightness, blacks and resolution even with a color wheel. See this comparison against the 5040UB and UHD65:
