The money-brains inverse rule applies here. Only ignorant cowsumers presume they are going to get a high-PQ imaging display in an environment laden with lots of ambient light. Its all about perception, and perceived PQ.
LCD, plasma, DLP, etc. are all technologies where the premise is to produce maximum amount of light 100% of the time, and try to block it when not needed. I cannot say if laser is being applied, here, to switch on-off rapidly enough to mimic what a cathode ray electron gun typically could do (which is to not produce light when not needed), but this may be where it is applied successfully.
And considering the natural expense of this technology, and the technology it is being compared to, one questions if the brains-money inverse rule is naturally applied.

LCD (Non-local dimming LED) and DLP do produce 100% of the light all the time, however, plasma and LCDs with local dimming LEDs do not. Plasmas do have some (less and less, especially with the Pioneers) light emmission even when suppose to be black but we are talking very very small amount, and Local dimming LEDs are basically the same, with less light being used when not needed. LaserVue, don't know, if its always on like an LED lamp or regular lamp.
