Digital Printing with LCD negative???

I posted this on PN in hopes of getting an answer I noticed that new digital printers are printing with some sort of an LCD negative that is lit by a light souce and projects an image on the paper. I would like to get such a contraptiona and use it in my enlarger. Basically it is a LCD screen that is connected to the computer as a second monitor and it exposes paper just like a negative would, but it is digital and open to all the digital manipulation. Does anyone know how this works, and where to get the LCD?

Don't know where you are located, but in USA try

Seems the Devere's target market is certainly not LF, but more like school portrait stuff.
