Tft Touch
Posted on Monday, February 15, 2010 in Photography
Can you damage a tft screen by touching it?
Hello,
My nephew was on my pc today and annoyingly pressed the screen to show me the game he wanted to play. I saw that pressured had been applied like when your fingertip goes white if you press it. Could he have done any permenant damage? It's only a week old and I am paranoid about it getting damaged as I don't really know how durable it is. Thanks
LCD screens are pretty durable, the worst your nephew will do is leave fingerprints.
LCDs work by moving long liquid crystals to alter the way that they polarize light. When you (or your nephew) touches the screen you are squeezing the liquid crystal and moving it out of position which affects the image.
As long as you do not push really hard, when you take your finger off the screen the liquid crystal will flow back to where it is ment to be.
