Because the screen costs $1500 and has the benefit of lower power consumption. Problem is that a 24 inch monitor takes about $15 to run 24/7 for a full year. You can run that for 50 years and still have a set-up that's hundreds of dollars cheaper with better contrast, can show colour, can show moving images etc. And if you put a motion/use sensor on it and connect it to a smart home setup, the energy use differences (e.g. reading the paper while brushing teeth) become minimal. We're talking about pennies per year. They're interesting as part of experimental art pieces, but as a large-scale consumer product very much unproven for these usecases.
