First and foremost, we have to make a note on what is optical fingerprint sensor, and how it works, will it be integrated inside Samsung’s Galaxy S8 flagship smartphone in 2017. Synaptics has officially made an announcement of what it claims is the industry’s first optical fingerprint scanner for smartphone and tablets, which is capable of high-resolution scanning through 1mm of glass with button-free design. More on this can be found right after this jump.
About optical fingerprint scanner, many thinks that are the oldest method of capturing and comparing fingerprints. However, the name suggests that, this technique relies pure on capturing an optical image, essentially a photograph, and using algorithms to debut unique patterns on the surface, such as ridges or unique marks, by analyzing the lightest and the darkest areas of the image.
This is how Optical Fingerprint Scanners work. Just like smartphone cameras, where the sensors can have a finite resolution and the higher the resolution, the finger details the sensor can discern of your finger, increasing the level of security. With that explained, these sensors capture much higher contrast imagess than a regular camera shots. These same scanning tools technically have a very high number of diodes per inch to capture these details up close. When your finger is placed over the scanner, it is very dark, so optical scanners also incorporate arrays of LEDs as a flash to brighten up the picture came scan time. Such a design is a bit bulky for a smartphone though, whereas slim form factors are important.
There is lot more to describe on the optical fingerprint scanner. The newly launched Synaptic’s Optical Fingerprint Sensor will work under the cover glass, including 2.5D glass and thus not need to take up any space on the front panel. The FS9100 optical sensor eliminates the requirement of physical Home button and glass thinning that was previously needed for capacitive scanners.
In the words of Synaptics description, the new optical scanners as excelling “with wet finger performance“. It also says that the new sensor is “durable, scratchproof, waterproof,” among other things. It’s said will also feature a thin layer and reduces power consumption.
The Vice President of Marketing at Synaptics’ Biometric Product Devision, Anthony Gioeli describes that sensors as “a new breed of optical fingerprint sensor technology that is designed to meet the needs of mobile devices, including the ability to image through thick 2.5D glass.”
From the past rumors of Samsung Galaxy S8, said to be getting rid of the Home button and to sport an optical fingerprint sensor and at latest announced by Synaptics confirms that was needed. Without an official confirmation, it still remains to be seen if Samsung really using Synaptics’ latest technology for its next-generation Galaxy S8 fingerprint scanner.
In that case, Synaptics’ new FS9100 optical fingerprint sensors are scheduled to sample in the first quarter of next year with mass production in Q2. This makes likely that its optical fingerprint sensor will debut with the Galaxy S8, rumored to launch during the Mobile World Congress (MWC 2017) in February.
