Hi guys,

Hope you´re enjoying the holidays.

I just arrived home with a used 17¨ LCD screen that I bought for my parents cube. However, I did a prety poor job when packaging. Actually I thought I did well, but some little particle passed and scratched the screen. My fault.

No pixels are broken just some fine scratching in a specific screen area. Do you know of any product that may help to reduce the effect.

Thanks so much and have fun

DISCLAIMER: I have not tried it. You are to blame for anything that goes "bad" if you try the method listed below.


I have heard that toothpaste might work for such a scratch if it's not too deep.

Myself, it would depend on the location of said scratch. If it was not in the middle or a critical location I would leave it. YMMV.

This is what you need. Good for many cell phone and PDA displays: http://www.displex.de/Languages/English/Index1.htm

that kit above is for cleaning the protective lens isn't it? Most LCDs don't have those.. well.. really they don't.

do NOT use toothpaste... some toothpaste's have a gritty abrasive inside which could further scratch your screen. are you sure the screen is scratched? maybe it's just a streak that would wash off with a wet cloth?

Listen to this person. Seriously.

Mine advice was only from word of mouth type advice. Not tried and true.

if you need to just clean it use cheese cloth, works the best!

I've heard the toothpaste thing too - again never tried it - but I heard that it was the gritty abrasive that helped... it worked like very fine sandpaper.

Anyone tried it?

Question:

Is the scratch in the LCD's glass layer or on a plastic "skin" over the top of the glass? Different manufacturers use different anti-glare techniques, which is what the plastic may be for. You will want to save the plastic if it has any.

If in the glass, eyeglass scratch remover liquids work wonders. I've used a few brands at different times, no problems. DO NOT USE ON PLASTIC SKINS! The softer plastic of the skin (unlike harder plastics of lenses in plastic eyeglasses) will discolor. Also, check the surface of the glass. if it has a rough feel or a frosted coating (both anti-glare techniques used by some LCD manufacturers), do not use eyeglass scratch remover - it will fill in the frosting/coating and create a glare spot. I do not have a method of removing a scatch from a frosted glass LCD. The toothpaste technique discussed above might do it as the frosting is basically a bunch of small scratches at irregular angles (in some cases, and a sprayed on coating in others), but I've never even heard of it before this thread, and never tried it myself, so I can't recommend it.

If it's on a plastic skin over the glass, did the scratch also raise the area around the scratch? If yes, you need to remove the buildup. I am used to model building, so I use a modelling knife (inverted V etch blade) to remove the buildup, then use a clear plastic patching epoxy (go to camping supply place the patch kits is for clear tent sides). Make sure you get one that says "optically clear" or "optically neutral". If no buildup, just use the epoxy. The important part of this is to get one that is optically clear.

I've used both methods several times (I work in a repair shop). Works on both desktop and laptop LCDs, no problems.
