Scratches on LCD - removal. Are there any ways to do this? Polishing an optician

Hello gentlemen, I dug the elke, but I did not find anything that would help in removing the scratches on the LCD monitor. Has anything changed in this topic? Here and there he writes on the Internet that the optics can polish them, maybe some of you practiced this topic?
Thank you for your interest, best regards ... Arek

In Media Markt (hence maybe in its sister Saturn) I saw pastes
for removing scratches on CDs and elements made of similar materials
artificial. The fact that it was a few years ago

Well, I read that these polishing pastes are not suitable ... so I'm looking for someone with practice ... someone who has already tried something, has some conclusions ... preferably constructive and positive

Sanding with pastes and even fine paper, e.g. 2000 deeper scratches on the display foil will then be visible in the form of shiny islands and next to them there will be matte transitions to the part that has not been grooved, unless
we sand the entire surface of the display, but for this it would be needed
a grinder, because without it it probably cannot be done, then we will get a homogeneous one
shiny surface, the problem is how to do it dry without liquids because how to protect the ends of the glass junction strips against the liquid. A good solution would also be to stick a foil for tinting car windows, but you can't dry it.

... and what would be the effect of sticking the film to car windows?
The scratch will not be visible?

If this scratch is such that you can only see on the blank monitor, it will help, provided that we get to the practice to stick dry without air bubbles because it has glue on one side and normally it sticks it to the wet surface of the glass and squeezes the water out, but here's the problem how to do it so that water does not get to the leads under the flexa and the problem is that the surface of the display foil is not as smooth as glass and has a certain roughness and is a bit dull so that micro bubbles may be visible because we will not be able to squeeze the water out well . Some monitors currently produced have such a smooth glossy foil and are distinguished by a much better picture. A box with a complete tinting foil, 3m long and 0.5m wide, costs a motor on the market. PLN 15. train well on a damaged matrix.

Supplement

I had read the mentions of anti-scratch toothpastes and thought the ones offered
in technical markets they operate according to the principle described in the publications
(this is how the seller described it to me):

Not as abrasive, but filling microdamages with transparent,
hardening mass with optical parameters similar to those
the material from which compact discs are made

You will not be able to see a delicate scratch, but it will be bigger and thicker, as long as you cannot see it when you look at the screen at an angle, it will be disturbing when you look straight at the screen. Another thing is the later troublesome detachment of such a foil from the matrix.
PDA users face the same problem when they touch the screen with the stylus.

The easiest way is to dismantle it and replace the foil from another damaged matrix. I'm talking about matrices in which you can see deformations by pressing your finger. In hard ones I would not move anything. In websites you can find dies with electronics crushed. The work is quite precise and there is a problem with dust in the air.
