this is how a CO2 laser work on glass:



The LCD panel is a different thing ..... it's still 2 very thin layers of glass, but the adhesive polarizer sheets in front and back of the panel are made in plastic, so they can be damaged from a watt or two (still, not as in the video) ..... and also the layer of "liquid crystals" fluid, can be damaged fr overheating ..... but, again, not as in the video .....
Yeah! Thats what I'm talking about!

Put an iphone under that, I would watch that!
