    I was showing someone pictures on my laptop there and they touched the screen a couple of times and it has a strange effect were you touch the screen like it goes a different colour.

    They screen appears ok but would touching the screen do any harm?

    There are several types of LCD out on the market on laptops. Some are more resistant to touch than others.

    On most modern laptops the screen would require a generous amount of pressure to induce discoloration.

    To answer your question, touching a screen to the point where it discolors is bad for the screen. It can cause issues like dead pixels for example.

    A simple test for dead pixels is available here - http://jasonfarrell.com/misc/deadpixeltest.php

    Dead pixels are not something to worry too much about, i have 2 on one of my monitors but i rarely notice them because they are conveniently located.

    As soon as they took their finger away from the screen the discolouration went immediattely.

    That sounds correct, when the pressure is removed from the screen the pixels will return to normal unless damaged by the pressure.

    In your case it sounds like you got away without damage.

    hate it when people come over to my monitor and do that... touching the screen to point stuff out.

    The fingerprints are bad enough - but I've got two dell monitors here (one laptop & one desktop monitor) with permanent bruise marks on them.

    I have seen "bruise" marks on many LCD tvs from small children hitting them. If your ever in the Topaz at Kill, Co, Kildare their TV in the seating area is in rag order!
