This year both Samsung and LG have launched flagship smartphones with near bezel-less displays, but in doing so removed one obvious site for a fingerprint scanner from their devices. Soon, though, a much-discussed in-display scanner could be an option, thanks to new technology from Qualcomm.
At Mobile World Congress in Shanghai, Qualcomm has shown off its new fingerprint scanning system, which is capable to taking readings through displays. The technology also works through thick glass and plastic.
Current generation fingerprint scanners are able to read through a glass and metal up to around 400 µm. However, Qualcomm’s new offering is able to scan through up to 650 µm of aluminium and up to 850 µm of cover glass.
