Isorg integrates full-screen fingerprint sensor on smartphone
Solutions currently available are restricted to single finger identification within a surface area of less than 10- x 10-mm. In contrast, Isorg’s FoD module supports one- to four-finger authentication across the entire dimensions of the 6-inch smartphone display, simultaneously. In addition, the module is very thin, less than 0.3 mm thick, so integration into smartphones is made easy for OEMs.
In addition to the image sensor, the module includes other hardware: optimized thin film optical filters developed in-house and driving electronics, as well as software from Isorg’s industrial partners covering the interface with smartphone OS and the matching algorithm.
The four-finger authentication capability builds a strong case for improving smartphone security for mobile banking and payments, personal health monitoring and remote home control applications. By enabling far more identification data to be captured with multiple fingers, it significantly reduces the risk of false finger identity theft. The screen-scale technology also brings ease-of-use advantages as people can conveniently place their fingerprints anywhere on the display.
Smartphone OEMs will be able to sample Isorg’s Fingerprint-on-Display module in spring 2020. In parallel, Isorg is also extending development of its FoD for application in the biometrics security market.
