Samsung's Galaxy S9 may not have an in-display fingerprint scanner but it might have the underlying technology

Samsung's upcoming Galaxy S9 smartphone may include a new display technology intended to make the device thinner and lighter, but the technology may have a second underlying purpose: to make it easier for Samsung to implement in-display fingerprint scanners.Samsung may now feel pressure to release its long-rumored feature after a small Chinese competitor announced a device with an in-display fingerprint sensor, which will soon release to market.
