LG invents a super-thin button-free fingerprint sensor

Pretty much every new flagship phone hitting the market now comes with a fingerprint reader, and that means each device features some sort of button or exposed sensor as well. That may not be the case for long, though, thanks to a new breakthrough invention from LG.

The South Korea company announced on Monday that it’s developed a button-free fingerprint reader that works from behind a glass surface. It’s also just 0.3mm thick, meaning it shouldn’t add much bulk to the device.

This should make it possible to include the new sensor anywhere in the device that’s covered in glass. It could even help keep the biometric reader safe from any damage caused by scratches and water.

LG’s new invention should also free phone-makers to experiment with new designs. The days of ubiquitous physical home buttons could be coming to an end. Instead, we could see more creative fingerprint sensor placements on future devices.

The company doesn’t say when its new technology will be ready for mass-production. However, it’s possible we could see the first phones packing the button-free fingerprint scanner launch later this year.
