Let's dig into the major types.īUDGET CLAMSHELLS. Most low-cost machines that are straight-up laptops (that is, models that do not have 2-in-1-type hinges or tablet modes) will not have touch screens, but you'll run across the occasional exception. Attention to detail matters here.ĭepending on the specific kind of laptop you're looking at, the tendency toward touch support will vary. Or there might be both touch and non-touch options available at 1080p. (Having to press a little to, say, sign your name on a screen is an earmark of resistive touch.)įor example, a laptop might offer a choice of a 1080p (1,920-by-1,080-pixel) touch screen or a 4K (3,840-by-2,160-pixel) display without touch support. When you write or tap on a resistive screen, that upper layer closes a circuit with another layer beneath it. 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. Based on our in-labs testing and deep-dive reviews, we've compiled a group of the best touch-equipped machines that have passed through our hands.
