Removing deep scratches from an LCD screen

Finer and finer grades of sandpaper, up to about 2000 grit, then polish with a buff and some plastic buffing compound.

But there is a good chance this will end up looking worse than the scratch, as you'll take off the anti-reflection coating in the area that you are polishing.

So you either need to do it to the whole screen, or, see if the top layer of the screen is removable and replace it with plastic/polycarbonate sheet.

Magic Eraser.

This. You'd need to treat the entire screen surface. LCD's are not perfectly glossy*, which is what you'll get once you have done your final polish on the affected area. You'd need to then polish the entire surface to match the repaired area.

*with good reason, it's terrible for viewability in all but the darkest rooms

I guess the next question would be the sanding techniques
Should I wet it or just go in dry? Circle or go in straight lines?

Wet and circular. Which means exposing the panel and its edges to water, which makes this even more of a stupid idea than it was three posts ago.

we have this problem at my office. Some ceiling works went wrong and 2 screens get this kind of damage. but it disapeared automagically in about 6 months. It seems that the cleaning people used some kind of strong all-surfaces cleaner. Ill try with some diluted dissolvent, alchool, etc a soft clothe and lots of patience all over the area, not only the damaged part. You could use a magnifier to see if works and change the dilution if needed.

Go to napa and get the headlight lens restore kit that comes with preloaded buffing pads. Dampen the pad and the area and buff out. If you need something stronger use the one for glass. Works beautifully.

If it has an anti-glare layer, you can try to remove it.

why not use a company that specializes in removing scratches from car windows

>>1132758
Protip: use toothpaste for the final buff. I use it to remove UV coatings from lenses.

Perhaps you can peel off the matte antiglare film and then apply a new one?

There's a good chance that whatever you do to repair that screen won't work really well. Removing scratches from glass and plastic is a bitch.

Scratches look bad because the diffuse light. Car scratch pens work to prevent the diffusion. Try one.

This is your only hope most screens have this layer if they are a matte finish

otherwise if its into the panel's outer surface its chooched

What about trying aircraft-canopy cleaner (don't know how you call it in your language but you got the idea) ?

This product is designed to remove scratches and impacts on plane glasses, because they are made in plexiglass and will flying you are very likely to collide with birds or random shitstones from space.

As a last resort I would recommend Chloroform, because it works like a charm to weld plexiglass sheets together, hence "diluting" the scratch with some drops may work

How bout tryin to live with it? Implying secondary monitor and thats the only scratch

Aircraft canopy polishing kits contain various grits of abrasive paper and polishing compound. Worth playing with anyway and the screen won't be nearly as hard as an aircraft canopy.
