Chinese smartphones manufacturers are making the in display fingerprint sensor with a optical way technology and it is not more accurate than the ultrasonic in display fingerprint sensor technology that Qualcomm is offering to Samsung.
How this ultrasonic sensor technology works?
It works by transmitting an ultrasonic pulse against the finger to map the pores and ridges that are unique to each fingerprint. This lets the sensor collect additional depth data for accurate 3D reproduction of the fingerprint to ensure higher accuracy.
The display panel will be supplied by Samsung Display and Qualcomm is said to be supplying the ultrasonic fingerprint sensor.
This is the first time we are hearing about Qualcomm making it. On before news Samsung was supposed making it and that will use it not only on smartphones but on smart home devices, home appliances and automobiles, as well.
However recent news confirmed Samsung is adopting the Qualcomm`s technology.
"Samsung Electronics has decided to commercialize the display fingerprint reader on the Galaxy S10," Samsung Electronics said in a statement. "We know Samsung Display is in charge of the display and Qualcomm is in the spotlight." Display Fingerprint recognition is the key to making fingerprints visible on the display without exposing the sensor to the outside. Samsung OLED reportedly an implementation of the display fingerprint in such a manner as to position the ultrasonic sensor on the back (OLED) panel. Qualcomm will be responsible for the supply of ultrasonic sensors and Samsung Display will be responsible for manufacturing the S10 panel and attaching the sensor to the panel. The ultrasound method is a technology for discriminating fingerprint shapes and features by changing the intensity and position of ultrasonic waves. Due to the nature of the ultrasonic transmission through objects, the sensor can be operated from the back of the panel. Samsung Electronics uses ultrasonic technology because the sensor is not exposed to the outside and has less influence on the panel structure and image quality.
Besides that , Samsung is working in more exciting new features for the 10th anniversary smartphone Galaxy S10 which will be unveiled at CES 2019 just before the MWC 2019 where the company is going to unveil its foldable smartphone.
