Re: LPD: Laser Phosphor Display - Successor to CRT?

couldn't this process likewise work for MEMS to rid the technology of the dreaded laser speckle (if the surface nanostructure were tuned to accomplish a kind of subsurface scattering?) I believe that speckle is an aspect of coherent light. It shouldn't be an issue with invisible UV laser + phosphor...

Re: LPD: Laser Phosphor Display - Successor to CRT?

So, if this is the case why in the hell are we chasing mini LED, OLED, and other displays that have so much blur? Imagine how much more utility our GPUs would have if you could drive games at just 60hz and with lower resolutions? I think the main issue is form factor. The mass market wants flat and...

Re: LPD: Laser Phosphor Display - Successor to CRT?

The pictures you linked to look very soft, doesn't even look remotely close to 720p, it doesn't look sharp at all. Really bad focus, looks blurrier than a lot of old consumer CRT's even. It really looks as blurry as an upscale. Heck it's probably doing uspcaling from 360p to 720. It's at least 540p...

Re: LPD: Laser Phosphor Display - Successor to CRT?

If you had a MEMS laser doing raster style scan out, and you used quantum dot pixels on the face of the glass as opposed to a traditional phosphor wouldn't you get the best of all possible worlds? Motion resolution Variable resolution inputs as opposed to fixed pixel infinite contrast great color w...

Re: LPD: Laser Phosphor Display - Successor to CRT?

A CRT rolling-scan emulator (electron gun simulator) on a 1000Hz+ OLED/MicroLED could still be able to successfully emulate the look of CRT refreshing, A display with these capabilities would be amazing, but I think it will be at least a decade before we get there. MicroLED does not seem to have a ...

Re: LPD: Laser Phosphor Display - Successor to CRT?

Nobody wants to use Phosphor in their displays anymore because they don't want phosphor trails. Was phosphor trail significant on CRT? I seem to recall it being more of a thing on Plasma. IMO the worst thing about phosphor is that contrast suffers in a lit room, since the phosphor coating is not tr...

Re: LPD: Laser Phosphor Display - Successor to CRT?

Good point, yes, it could be interlaced which theoretically might deliver a progressive refresh of 180Hz - still quite good if it's single pass scanning. If RGB sequential I guess it could be considered equivalent to 120Hz. Personally, I do see "rainbow effects" with DLP and similar tech, and find i...

LPD: Laser Phosphor Display - Successor to CRT?

Did some searching and was surprised to find that this technology was not discussed here. Essentially, it is a rear projection display using a scanning laser (ultraviolet) which excites coloured phosphors on the screen - Very similar principle to CRT (which steers an electron beam instead.). There i...
