It's not the glass. You could get a glass LCD panel and it still wouldn't work.

LCD/plasma doesn't work because their light/dark contrast isn't good enough and their response times are an order of magnitude too slow.

There's a photodiode in the gun that looks for a strongly contrasted light. If it sees one, it registers a hit. Timing is critical since the game flips between different white target boxes on the screen a bunch of times for only a few milliseconds each when you pull the trigger. So if the gun registers a hit while duck#2's box is on-screen, the game knows you shot that duck and not duck#1.

The NES Zapper has no idea where you're actually pointing, and you can fool it by firing directly at the sun or even a light bulb.
