The Loki is a dedicated residential platform with significant development over the F90.
I'll try and get some real details up for you tomorrow.
Neil, this is what Tim told me after he asked his developer, present at the demo. I also heared the developer say this as I was sitting next to Tim, when he asked to make sure following my questions. Since I was told the F-90 would also 'do Rec. 709 guaranteed' at full brightness, I wanted to make sure what the difference(s) was. Then I was told the statement as posted above.
The loki will (undoubtedly) have significant development over the F-90, but I was told the demo unit had relatively little yet, as they had only just received the platform and were just starting further development. It will need to have further development over the F-90 to begin with in the contrast department as the F-90 is specified at only: "Contrast ratio 400:1 native, 1800:1 Full field".
I was told the development teams have been integrated but it was indeed developed in Norway. The case and lens definitely are classic PD design, only larger.
Yes it does use a standard 0.9" WQXGA, 2560x1600 DMD with a two position pixelshift for around 8.15 million pixels. Shifting comparable to TI's XPR Technology, but developed and owned by Barco, unlike XPR, that is fully developed, owned and promoted by TI.
Edit: I just read the white paper on Single Step Processing (SSP™) image processing technique from Barco,and it claims 16 million pixels, but the 0.5 pixel diaganol shift would suggets there is a quarter pixel overlap, at a minimum.
Re: ISE: Barco F90 4K projector
TI 4K pixel shifting technology as explained by Barco
TI told me the pixel shifting would in principle work with all of its DMDs, but it was only focussing its efforts on the 0.67" Consumer 4K DMD.
Panasonic does have its Quad Pixel Drive Technology that by design does overlap pixels, using four positions in its shifting mechanism. This also uses the 0.9" WQXGA DMDs, only three of them.
So the linked CE article is not correct as to this being 'the first 9in 4K DLP laser phosphor projector in the world', as Panasonic has been shipping its PT-RQ13K since November 2015, after first showing/launching it at ISE 2015.
Well the Laser-Phosphor units are currently sold at a premium. They can offer 3 DMD light levels (12/13K lumens for the brightest from Christie/Barco, Christie also at 13K if using the new ISO scale), so there is a (slight) discount compared to some of the older 3 chip designs.
the base platform is 120 fps capable, so no reason it should not do active 3D at 60fps. The mentioned Thor is a completely different beats, a fully fledged 6P laser projector, so capable of 6P 3D, so seperation through frequency off-set in the second set of RGB primaries.
