Doing a bit of quick math that works out to the LED tiles in the MSG Sphere having a 9mm pitch between pixel centers. For a large venue with 17,500 seats and substantial viewing distances the image should look pretty solid.
Any traditional jumbotron LED tile has a nearly solid, black, hard plastic front with rows of plastic louvers between the pixels. There is some metal frame work behind the tile face that holds components and various connectors for power and data. Usually one or more fans are incorporated into the tile back too. Some LED signs can ventilate hot air out of the front. But I don't think the holes in those product designs are big enough to allow audio to pass through effectively. They basically need to come up with some sort of "cheese grater" kind of tile face that allows a lot more air to pass through it. But the design has to be such that it doesn't ruin contrast levels. It's a big challenge. I'd really like to see more closely what MSG Entertainment has done with the sound system for the Sphere. The one in Las Vegas hasn't finished construction. Yet they're already working on a second Sphere venue for London.
Are there really cinema chains that might spend money to repair a bad pixel on an LED screen?
