So, with our three-eyed monsters we have three tubes with their unique blend of metal halide phosphors. The same electron beam is used (I think, but boy howdy correct me if I am wrong) setup is used in each of the three tubes. This means that the metal halide itself, and maybe with some color correction outside the tube, is responsible for the color we see from each tube.

So, what would happen if we were to mix the raw metal halides into some sort of homogeneous method? I presume depending on the ratio of the green/red/blue-exhibiting metal halides, we'd probably get white light. But what if we were to remove the electron gun (and electron beam) and replace it with something along the SED setup?

First, the problem I see with SED/FED is the ability to initially mass produce large pixels. This isn't surprising as their initial development was for the application of flat panels. But that seems more challenging than say direct application to large screens. Make the image area a lot larger and you can make the pixel substantially larger.

By making the electron emitter larger the production of viability increases. Using an electron emitter such as that used in SED/FED also eliminate the need for a vacuum. And while the stark differences between the two xED devices are in their processing (one being truly a nano-fabrication and the other analogous to inkjet deposition), they both achieve the boob-tube end result without a vacuum.

So, scale the emitters up in size, and make them capable of different frequencies (think wave division multiplexing). Now make the phosphor forward screen a homogeneous mixture in which the respective halides respond only to different emitter frequencies.

What would such an approach achieve? No more sub-pixels. Hmm, I may be trying to think outside the box, but my box may have been thrown out of the house already. Just a thought.
