This is in contrast to the resistive touch technology you might see in other implementations of touch screens, in which the upper layer covering the screen flexes. That electrical aspect explains why touch screens don't work if you're wearing gloves. This layer is typically a grid of ultra-fine wires, or a film it needs to be subtle or translucent enough to not interfere with viewability. Most modern laptops make use of what's known as capacitive touch input, in which the over-screen layer detects where you've touched with one or more fingers using the conductivity of your skin. In most cases, a touch-screen-equipped laptop has a conductive digitizing layer, overlaid on the panel element, that allows for tap, pinch, or swipe input. Below, let's run through the basics of laptop touch screens and why you might (or might not) want one.įirst of all, some terminology.
