I don't know well the market but my impression is that if they follow that path they will become commodities producers.
They don't want to be only displays manufacturers because then a TV would be only an accessory. They want to capture a market. They want to be "the platform".
In other words, everybody wants to be Apple.
Crowfounding would be a nice idea but I imagine that the technology for good screens is only in the hands of, precisely, the ones that are trying to make TV a platform.
