Quoted from MTPPC:Well, I can see where 7" screens could be embedded like inserts and an overlay is used to make it look non-rectangular in key places. Obviously you cannot have pop bumpers and slingshots poking through an LCD. But none-the-less, who would have dreamt the ubiquity of microwave ovens during the early days of the space program. You need to have big ideas to end up with little improvements and the current cost of a technical innovation should never be used to eliminate any opportunity for further development.
If you want to talk about creative use of LCD, go look at some of the latest slot machines out there. Not only do they use the hell out of traditional LCD screens, they have a newer tech that looks like an LCD suspended inside the glass that protects the display. You could start putting those kind of "screens" directly on the playfield with a polycarb cover to protect from the ball.
