This has nothing to do with the yellow subpixels Tv's that came out a few years back.
(Which BTW i agree with you both of you about.)
This is very different.
And let me explain RHD why the choice of wavelengths so there will be no confusion.
I own 5 showwx+ models.
Some have different wavelengths because some were made by Intel and some by Microvision.
My 442nm blue can not do royal blue or true blue and instead does a purplish blue.
My 450nm does true royal blue.
And although the red and blue laser wavelength variations have little impact on gamut color they do with overall precived brightness.
In the wavelength region of red for instance, luminous efficiency rapidly increases as the wavelength shortens.
Current red laser diodes used in the older showwx+ display engine lase at 642nm. By moving towards the shorter wavewavelegth, even by a mere 4nm the human eye perceives this red light as being much brighter. In this case, at fixed brightness, red light at 638nm appears about 33% brighter than the same light output at 642nm.
Similarly, the blue laser diode being used in the previous version of the wx + emitted light at 442nm. By increasing the wavelength to 450nm, precived brightness would also increase. That is why I have included 6 of those specific wavelengths in my monitor setup.
Then you have the overall brightness increase by using 7 lasers instead of 3.
(Side note: I would love a 405nm 3.8mm laser to add in the mix but cant as I don't think they make one that can modulate as fast as the ones made by Osram that go in the showwx+ .
The 7 color laser display I am building will still look better at color reproduction than any other display when you take these things into account.
(Read post number 5 in this thread)
By the way RHD, did you ever get the green laser working outside the projector at full power? I was curious to know if you messed with it anymore since you posted about its while back. (I was wanting to use these lasers as a cheap method for making color holograms since they don't mode hop and have long coherence.)
I hope this cleared some things up.
