LCD pressure marks - what they are and how to fix
I have an LCD with several small pressure marks about the size of the eraser end of a pencil.
Can anyone explain what exactly happens when a pressure mark is created?
Is the mark dirt or a scratch on the inside or outside of the screen?
Is it damage to the actual pixels?
Are they caused by touching the screen? If so, why?
Is it possible to fix the screen by eliminating or reducing the pressure mark?
Cleaning the screen with isopropyl alcohol has removed various other black marks due to contact with the keyboard but these pressure marks remain.
Any advise or comments about LCD screen construction, how this relates to pressure marks and if it is possible to fix would be appreciated.
Does anyone know a website which gives such information?

"...due to contact with the keyboard ..." and it is on the surface of the screen,
not affecting the pixels, but since it is a removal of material, no removal of
the marks would be practile.
Keyboard should never contact screen, there are usually rubber bumpers on screen
lid to prevent contact, D800 has eight of them and LM has none, but no screen/keyboard
contact has ever occured.
Most likely cause woul be a too tight packing for travel, with great pressure on
closed lid to cause contact, prevention would be to avoid packing that tight, as
well as checking 'bumpers' and posssibly adding more and thicker bumpers.
I would Google Search for some sort of antiglare coating that might be applied
to replace what is gone, this would need to be done with great care to look
better than it does now.

Thanks for the comments.
Anyone else have any further suggestions, particularly about the antiglare coating and if it is possible to repair it in any way.
