This Is How Touchscreens Actually Work

Touchscreens are everywhere these days, and even though you've probably heard people mumble about the relative benefits of capacative screens compared to resistive ones, you might not actually know how they work. This video explains.


Greg Foot describes how reisistive screens work, before explaining how Apple swung the market in the other direction, to favoring capacotive screens instead. That's what the bulk of the video's really about: from the simple business of registering a single touch, through recognising complex gestures, and the implications of more recent advanced like in-cell screen technology. It's a great little introduction to how touch screens works; well worth watching. [Head Squeeze]


Great video.. but why the Apple plug? man I always find it amusing when people give Apple credit for something they really deserve no credit for.

Capacitive technology was too cost prohibitive for most touch devices. Apple designed the iPhone right around the time the manufacturing prices for the tech became reasonable.

They were not the first to use it, they were not the creators of it. Steve just said; I like this one better, let's use this one. They basically just bought the screens from LG ans Samsung.

The same decision most touch device makers made around the same time.
