One of the features we expect to trend in phones this year is the under-display fingerprint scanner. Vivo’s X20 Plus UD is the first phone to launch with it and the Vivo X21 has a UD variant too. Reports from Taiwan says the Huawei Mate 20 Pro will also launch with an under-display fingerprint scanner.
Sources say the manufacturer’s second major flagship phone which will launch in the second half of the year will come with Qualcomm’s own under-display fingerprint scanner.
Almost a year ago, the chip manufacturer released plans for its under-display fingerprint scanner scheduled to launch in commercial devices by Summer 2018.
Qualcomm’s fingerprint sensor is said to be three times more expensive than regular capacitive sensors but is actually thinner at 0.44mm. It can also work under glass up to 800µm thick (1200µm according to Qualcomm’s own infograph from last year) unlike a capacitive fingerprint scanner that works with thickness between 200µm and 300µm.
It is also reported that we may not see the iPhone X‘s Face ID sensor replicated in Chinese phones as the sensor cost as much as $60. This will significantly drive up the final cost of the phone. It is also said that the technology requires lots of work with respect to software and hardware integration.
Another reason is that locally manufacturers may infringe on patents especially for Chinese phones that are sold in other markets. So, the plan is to launch phones with the same face unlock security as Apple’s Face ID locally first. This will help gauge reception and reduce risks of failure. While other models sold outside China will feature under-display fingerprint scanners.
