In-display fingerprints sensors are apparently the next big thing in the smartphone world, as companies continue to fervently pursue the technology. Both Huawei and Vivo have managed to use in-display fingerprint sensors developed by Synaptic, but for the longest time, Samsung has been the one who everyone expected would implement the technology first. It seems that the Korean tech giant is yet again going to delay the use of the new technology, pushing it to the launch of the Galaxy S10.
Previous rumours had suggested that the Samsung Galaxy Note 9 would ship with an in-display optical fingerprint sensor. This piece of information comes from Chosun, who say that Samsung is going to wait for the technology to become more reliable and faster before implementing it in their flagship smartphones. The decision seems like a sensible one, given that various hands-on videos of the technology in use show that the in-display fingerprint sensor is noticeably slower than a capacitive fingerprint sensor. The report further says that Samsung is looking to implement the technology in more than just its smartphones, expanding the scope of use to appliances, IoT devices and more.
Rumours of Samsung using the in-display fingerprint sensor have been around for almost two years now. Initially, Apple was rumoured to use the tech for their upcoming special edition iPhone X, but when that did not happen, it was said that Samsung would beat Apple to the prize. Initially, reports said that the Samsung Galaxy S9, followed by saying that wouldn’t be the case. Right after, there were suggestions that the Galaxy Note 9 would have the in-display fingerprint sensor, and now, we’re hearing that won’t be the case because Samsung wants to wait.
Currently, in-display fingerprint sensors have been developed by Synaptic and Qualcomm. The Vivo X21UD comes with an in-display fingerprint scanner, which is an optical sensor instead of ultrasonic, resistive or even capacitive. When the user presses his or her finger against the display, the pressure is registered and the OLED emits light to illuminate the finger. The reflected light is captured by the optical sensor and high-resolution image of the finger’s ridges are created for authentication purposes. Qualcomm’s implementation of the same technology employs ultrasonic waves that can travel through OLED panel up to 1200 μm thick to accurately create a digital image of the fingerprint. While both implementations have their strengths, they share a common weakness - speed. Neither is as fast as the current capacitive fingerprint sensor that we’ve got so used to over the years. Given this, it makes complete sense for Samsung to hold off from putting in-display fingerprint sensors in their flagship phones.
