Samsung will debut its in-display fingerprint sensor on the Galaxy S10 when it launches around March next year, not on the Galaxy Note 9 that will be released this August.

There have been conflicting reports on when the Samsung fingerprint sensor in screens will be rolled out. A new report from the company's home country of South Korea, however, looks to end all speculation.

Samsung Galaxy S10 To Launch In-Display Fingerprint Scanner

According to Chosun Economy, the Samsung Galaxy S10 will launch the in-display fingerprint scanner, a feature that some were expecting for the upcoming Samsung Galaxy Note 9.

There were some reports that said it will be among the Galaxy Note 9 features, while some reports said that the in-display fingerprint scanner will be pushed back to the Galaxy S10. It was also then said that Samsung would be making the final decision in the near future, and it looks like the company finally did.

Samsung reportedly informed its suppliers that it will no longer proceed with integrating the in-display fingerprint sensor into the Galaxy Note 9 and will instead introduce the feature with the Galaxy S10.

Samsung will not be the first company to offer an in-display fingerprint sensor, but its technology is believed to be superior compared to the systems used by Chinese smartphone manufacturers.

The current flagship smartphones of Samsung incorporate the Infinity Display, a design where the screen takes up most of the front of the devices. To achieve this, Samsung eliminated the home button and moved the fingerprint sensors to the back of the smartphones. However, starting with the Galaxy S10, the fingerprint sensors will be embedded underneath the screen using a technology named "fingerprint on display," or FOD.

How Will The FOD Feature Work On The Galaxy S10?

Current optical sensors capture reflected fingerprints between and through OLED pixels, which makes them easier to implement as in-display sensors but with reduced accuracy. Samsung is working on ultrasonic sensors to address the accuracy issue.

The sensors will work by transmitting an ultrasonic pulse against the user's finger. Some of the pulse is sent back to the sensor, capturing the minute details of fingers, such as their pores and ridges. This creates a very accurate 3D replica of the fingerprint.

The ultrasonic in-display fingerprint sensor will not only be included in the Galaxy S10 features and those of future smartphones, though. Samsung is said to be planning to use the technology on other devices, such as smart home devices, appliances, and even automobiles.
