Fingerprint sensors in smartphones are still not generally mainsteram within handsets, such is the case with many new features or specs when they first hit the market inside of devices. So far we can only generally expect to see them inside of high end Samsung flagships and current as well as future iterations of the iPhone. Fingerprint sensor technology inside of our mobile devices are made up of biometric sensors, but up until now we have really only seen them implemented inside of home buttons. One company that specializes in manufacturing biometric sensors feels there is a better way to make use of the fingerprint sensor however, and along with it a better place to put it. Under the display.
CrucialTec is that company and they're said to currently be in development of a biometric sensor that can be used on the underside of the display panel, and they have announced today that have just been awarded the patent for this technology. When you think about it, using the fingerprint sensor inside of the display makes a lot of sense given your fingers already touch it likely hundreds if not thousands of times in a given day. News of the report about the South Korean company comes from Korean news media The Korean Herald.
While sitting under the display makes sense for the placement of a fingerprint sensor, there is another element to this being the area where it resides, and that's the fact that smartphone and mobile device OEM's would have one more reason to leave the home button behind on future mobile device designs. Currently with phones like the Samsung Galaxy S5 and the Galaxy Note 4, the home button serves a purpose for more than just being the home button. Swiping up from this location also activates the fingerprint sensor tech and allows users to unlock their devices. It seems this was a main focal point in getting the patent and developing this type of technology, so that smartphone OEMs could have a little more room to play with the design of devices that would allow for the removal of a hardware button. We likely won't see this type of biometric sensor tech inside of smartphones from Samsung or other OEMs anytime soon, but now that it's out there we can't wait to see what manufacturers come up with when it becomes available.
