Say bye to the fingerprint button, hello to glass

LG's Innotek arm unveiled a new fingerprint scanner implementation today that allows a scanner to be placed directly under a piece of glass, such as the bezel area of display cover gla$s on a smartphone. The new technology, then, is at least somewhat similar to Qualcomm's Snapdragon Sense ID in that it does not require an exterior element physically demarcating where the scanner sits, and can instead be basically invisible. Qualcomm's solution, though, uses ultrasonics to identify a fingerprint - LG's design appears to be of the traditional capacitive variety.

To be clear, the new technology does not allow the scanner to sit on or under the display itself - this is a problem not yet solved - merely for it to be hidden a bit better in the places where we see fingerprint scanners already.

While the technical achievement here is not in question, I do have to wonder what exactly the end user benefit is to this design versus a scanner that is part of a button or a dimple on the back of a device. After all, the button or dimple serves as the guiding point for the finger to line itself up on the scanner. Without a physical cue, it may prove harder to place your finger exactly where it needs to go to get an accepted read.

LG, for its part, does make a point that the new design helps with waterproofing, but it's not as though Samsung has had much trouble making the button-scanner water-tight on the Galaxy S7.

It's unclear when or if we can expect to see this new technology in LG's smartphones.
