LCD (monitor) screen construction

I've rescued 6 all-in-ones that I was hoping to drop off at one of the local schools. But, noticed that all of them have cosmetic "defects" in their screens; not electrical but, rather, mechanical.

It looks like the screens may be fabricated from a multilayer clear plastic assembly and the outer layer has been scarred... as if there was a set of blisters in the material that were "popped".

While still usable (it just obscures those blistered portions of the screen), I'm hesitant to gift something with such an obvious defect.

Is there a way to fix/recondition this outer (blistered) surface? Or, should I just gut them and return the scrap to the tip?

[there's not really a lack of rescue-able machines so I'm not going to spend much effort trying to salvage *these*]

Cigarette burns? I've never seen damage like you describe...

A picture is worth a thousand words here.

My LCD screen is definitely behind a clear protective sheet of plastic. I can tell this because in the summer when thrips are about I end up with a few moving thrip shaped dead pixels that have got inside it. Dead ones eventually fall to the bottom and slowly accumulate.

My guess is that the top surface is damage protection for the display itself and might be swappable. The only way to find out would be to carefully dismantle the worst one running the risk of wrecking it.
