More info at "http://en.wikipedia.org/wiki/Laser_television".

Laser TVs are nothing new and I there was a DLP competitor 10 years 
ago (Grating Light Valve) which is laser based and is still trying to 
penetrate the market.  I believe that Sony purchased this technology 
and has done nothing with it.

When LED based DLP displays were first demoed, they had extremely 
saturated colors which were quite impressive with their saturation but 
would cause anyone here to go haywire.  These products have now been 
in the market for over a year so presumably the colors were made more 

The most important issues will be with dynamic range (usable black 
levels), gammut, and accuracy.  If the laser output can be directly 
modulated, then dymamic range can be improved dramatically.  If 
micro-mirrors are used (as in DLP) then the dynamic range will not 
improve quite as much, but it seems that light leakage (backscatter) 
would be significantly reduced so the dynamic range would still be 
improved dramatically.
