Samsung To Introduce In-Display Fingerprint Sensor In Galaxy A Series
2018 has been the year of in-display fingerprint sensors in smartphones. We have seen an increasing number of companies adapting this technology, with most of the latest flagships having the same. The next big thing is the arrival of this technology to mid-range and budget phones. And it looks like Samsung is already gearing up to do the same. Latest reports say that Samsung has finalised a supplier for in-display fingerprint sensors for its A series lineup.
The report details that the Galaxy A series in 2019 will feature an in-display fingerprint sensor. However, this will be an optical sensor and not the ultrasonic sensor, said to be on the Galaxy S10. The way optical sensors work is by reflecting light of the finger. Then the cameras capture this image and use an algorithm to detect the unique patterns on a person’s hand. This differs form the ultrasonic fingerprint sensor which uses ultrasound to map the patterns on your hand. This is so detailed that it even registers the ridges and sweat pores on your fingers.
Optical vs Ultrasonic
While the optical fingerprint sensor is more favoured by most smartphone manufacturers, it lacks in many areas when compared to the ultrasonic sensor. However, companies are willing to use it as the ultrasonic sensor costs 3x more than the optical sensor.
The Galaxy A series is Samsungs mid-range series of smartphones. This year, Samsung tried to win over the segment by adding a number of cameras and gradient colours to the devices. Some of the latest A series phones are the triple camera Galaxy A7 and the quad camera Galaxy A9.
While we knew from earlier reports that Samsung is planning to integrate this technology in its upcoming flagship Galaxy S10, this news came as a surprise. However, considering the position that Samsung is in right now, it seems like a logical step. With its grip over the smartphone market decreasing day by day, Samsung needs to ensure it packs each and every device with the latest features.
