While at home today, I pressed my laptop screen. A small rippled area came around my finger where I pressed it. Why did this happen?
God, you amaze me! this is honestly previous words. i think of i'm going to easily take a seat and watch the ripples for awhile, by using your image, this is. you write ideal words mutually with your digicam!
When you press on an LCD panel (liquid crystal display), you are flexing the panel, which distorts the liquid crystals, which in turn changes the way the light from the backlights behaves - the ripple effect on the screen. If you drop a stone into a pond, it produces ripples spreading out from where the stone hit the water - similar principle. Don't press hard on an LCD screen - the glass is very thin and breaks easily.
