Having the fingerprint under the screen was once an important feature. Nowadays, optical under-display fingerprint sensors are available even on entry-level devices. However, ultrasonic fingerprint sensors that detect even dirty and wet fingers have not become widespread yet.
One of the main reasons for this is that this technology is still expensive. According to Digital Chat Station’s post, the affordable ultrasonic under-screen fingerprint sensor is entering mass production. Accordingly, Chinese Goodix pushed the button for this technology.
Is affordable ultrasonic under-display fingerprint technology coming?
Perhaps one of the most well-known disadvantages of optical under-screen fingerprint sensors is that they cannot detect fingerprints when the finger is dirty. Another time-wasting situation is that the fingerprint sensor does not unlock at once when the screen is off. Although the ultrasonic sensor provides a solution to this problem, it is only seen in high-end devices. Goodix is preparing for mass production of a technology that will change this situation.
Especially Samsung and Qualcomm are at the forefront in ultrasonic fingerprint sensors. However, Goodix stands out with its proximity to Chinese companies and its price advantage. Especially with this situation, the possibility of ultrasonic fingerprint sensors appearing in middle and upper-middle segment models increases.
Digital Chat Station is known for accurately reporting technology leaks, especially from Chinese companies.
According to Digital Chat Station, Goodix is in talks with China’s five largest smartphone manufacturers. Judging by this claim, there is a possibility that giants such as Xiaomi, Vivo and Oppo will come up with affordable smartphones with ultrasonic under-screen fingerprint sensors in 2024.
Ultrasonic under-display fingerprint scans the pores in the fingerprint with sound waves. After this scanning, a three-dimensional model of the user’s fingerprint is created. When unlocking the smartphone, this created three-dimensional model is compared with the newly scanned fingerprint model. Since this process is done through sound waves, the screen turns on even if your finger is dirty.
This under-screen fingerprint technology can also recognize dirty, oily and wet fingers. Since sound waves are used instead of light, dirty and wet fingers do not negatively affect fingerprint scanning.
So, what do you think? Could ultrasonic fingerprint technology, which can be unlocked even with a dirty finger, appear in more affordable devices? We are waiting your comments.
