Has been tested by Heighway I believe, 46 inch display as playfield cover. I believe Andrew said that the technology is not for now. But maybe in the future the are going to use it.

Love this idea! I have seen arcade games that utilize a see through LCD screen.... this has got to be possible....

Here is a quote from an article concerning Heighway Pinball:

'Deluxe models, due later this year, will have a 46" transparent screen that resides over the playfield surface and below the top glass. With images and video appearing and disappearing during play, the transparent screen will reportedly provide truly immersive experience. But core gameplay remains true to tradition with plenty of ramps and drop targets. The digital technology, Heighway explained, is intended to enhance traditional play, not replace. - See more at: http://vendingtimes.com/ME2/dirmod.asp?sid=EB79A487112B48A296B38C81345C8C7F&nm=Vending+Features&type=Publishing&mod=Publications%3A%3AArticle&mid=8F3A7027421841978F18BE895F87F791&tier=4&id=D7587242D4C24F48A59309F15CD7DBB0#sthash.MQF20Wjv.dpuf

smart glass, been around a while, my friend barry been doing neat things with it . he did bathroom partitions in a restaurant that shaded out when you close the stall door.
this would have been awesome on the Hobbit, smaug multiball , flying dragon breathing fire all across the playfeild .

I wonder how expensive the tech is. It seems like it would depend on the height of the person and viewing angle could impact alignment, right? Might it also be detrimental to have a lot of GI light shining up through the glass when there's an image being displayed?

I personally would rather see Augmented Reality integrated into a physical table that involved a headset.

in a HUO environment that could work but would be messy on route.

A home environment is all I care about!

Honestly, though, route pinball isn't big in my area, so it's not like if anything with AR or even this transparent TV was introduced into pinball that I'd ever see it in person locally on route.

Besides, with the right setup, a headset can work on route. I remember a Doom arcade game with a headset at my local arcade in the 90s. You would just have to set it up in a way where it's not just a headset on a cord that can be tossed around. It would have to be mounted to some kind of frame in front of or surrounding the pin. Then there could be a separate screen that shows bystanders what the player is seeing.

I believe the screen is a little foggy and dark and you'd need crystal clear for a playfield glass.

This is really cool on slot machines. I think I would hate it on pinball machines. We pay $300/sheet for invisible playfield glass, do we want to pay even more than that to put a bunch of semi transparent crap blocking the view of the ball?

Doesn't interest me. You're going to run into some issues with varying heights of the player and images lining up.

Ball strikes could be very expensive...........Don't F'Up while rebuilding a flipper............
