LG shows off a smartphone display panel with integrated fingerprint reader

Future smartphones may no longer need a dedicated button for unlocking the device or performing other actions with a fingerprint.

Fingerprint readers are practically a must-have feature now. LG Innotek, which is the components subsidiary of parent company LG, is showing off a new capability that might make unlocking your device in the future even easier.

The company shared some details about an under-glass fingerprint sensor module, which would allow you to place your finger on the smartphone’s glass for identification. This would eliminate the need for a button, which you’ll find on the bottom in Samsung’s Galaxy S7, and on the back of phones like the LG G5 and Nexus 6P.

LG says it cuts a tiny groove into the underside of the glass for installation of the fingerprint reader. It’s an intriguing concept, but it doesn't mean you'll be able to touch any part of your device to authenticate with your fingerprint. There's still a fingerprint reader module at a particular location (in the bezel, not where the display is), it's just underneath the big sheet of glass that covers your device. Sort of like capacitive buttons.

The story behind the story: LG isn’t the first to march into this territory. Apple filed a patent for a similar technology, and Qualcomm and Synaptics announced this type of component last year. An LG spokesperson told The Korean Times the company is in talks with handset manufacturers to bring this to market within the year. You’d think the parent company LG would be an ideal place to start.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
