All these units have failed to do much at all in the market, despite the seemingly obvious benefits of LED even over blue laser + phosphor. I really want this to be a tech that can provide competition in the market - there is a lot to like about solid state LED in theory. What do you think it is that constantly holds it back?
Just in general Id think light output and the corresponding black level. While lasers are definitely going to help with light output, black levels are going to be even higher until we get some type of upgraded modulation like the eclipse in lower price brackets. There also seems to be a big gap between the portables and something like the benq I think due to the optics necessary to prevent misconvergence/chromatic abberations due to the narrower band output of the leds. And I think sacrificing contrast for resolution, as these .95 dmds were already very sharp and detailed.
What rgb solid state does with a dmd in terms of video rendering though is astounding. The only flaw would be black level, its perfect looking aside from that. Perfect mtf with no overshooting, perfect motion with no blur, perfect color rendering and color depth, excellent native gamut. The benefits over a color wheel are numerous and it really improves the performance of dmds.
Specifically with these older units
-Where the ht9060 can do 1400(?) lumens the sim2 mico was 500-600.
-The optics needed for the .95 dmd and especially for the narrower band output of the leds(chromatic abberation). The Delta units show quite a bit of CA, the chi lin less, and the barco/pd units(FL32 etc) were mostly free of it due to the very high quality minolta konica lens.
-The cooling thats needed wasnt quite so common in projection I think like it is now with higher powered leds and lasers, i.e. water cooling, large heatsinks with heatpipes.
-These units were a bit before their time in terms of gamut. But madvr like with everything enables the projector to show uhd material, high quality downscaling, 3d luts, and tone mapping. Specifically the Chi Lin units make for a very uhd image. 600 lumens(26fl on a 100" 1.3 gain screen) at the native gamut, a 2.5k:1 native contrast, 12.5k dynamic contrast(measured 7-8k at 1% adl) with excellent functionality(gamma corrected and water cooled leds), 900 ansi contrast(very little haloing), red hits the bt2020 coordinates and green is at about 0.73 I think. The high pixel fill and lens, along with the high mtf and color rendering make for a very sharp, detailed, natural, and dimensional image. Color performance is really excellent and really improves perceived contrast, low level color detail, motion accuracy(no bright ghosting due to overshoots in fast motion in dark scenes), etc.
