Polishing Glass (on TFT preview screen)

[deejayry]

Hi guys.

I've just repaired a 4" 640x480 TFT screen that i had bought for a computer project about 5 years ago, but it stopped working mysteriously, i just assumed it was totaly dead, but last night i decided to have a look and see if i could find the fault, it turned out to be an SMT fuse which had blown, so i bridged it with a strand of 0.5A wire and it came to life when power was applied.

The idea is to use this screen to make focusing my fuji s9600 digital camera easier. i'm just about to order the materials i need to give the screen a nice case and alow me to adjust its gain and switch between 2 inputs, 1 will be a CCTV camera which i will use as a finderscope and the other will be the Fuji camera.

the only problem i have is that when in storage the screen has become scratched, can someone suggest what i can use to polish out the scratches?

Thanks for that link, looks good... for large panes of glass but i think it may be a bit dangerous to use on the TFT, i'd be worried about catching an edge and flinging the screen across the room!

I think i'd prefer somthing that uses more "elbow grease" than power tools.

From above site:

Note: Do not use on Lexan, Plexiglas or clear plastics.
Which brings up the question...Is the monitor screen glass or plastic?

It is actually glass.

If it were plastic i would pull out my acrylic polish i use for my polycarbonate windows of my car ;)

With some types of glass I've had good luck filling the scratches with super glue then after it dries, polishing the glass to remove the excess and give a smooth surface. If the index of refraction doesn't match acetone will disolve it out and you can try something else. A glass shop should have some ideas as well.

Thanks for that bit of advice Rick, i will give it a try when i get round to housing the screen.
