Fingerprint sensor authenticates via smartphone’s display
Believed to be the largest surface fingerprint-on-display (FoD) module, designed with organic printed electronics, a four-finger authentication module by Isorg will be demonstrated at CES 2020.
It is expected to bring higher data security to mobile devices, says the company. The company specialises in organic photodetectors (OPDs) and large-area image sensors and will demonstrate the full-screen Fingerprint-on-Display (FoD) module which supports up to four fingers simultaneously touching a smartphone display.
Isorg’s FoD module responds to demands from OEMs and end-users for higher security technologies that can support large surface area fingerprint sensing. Solutions currently available are restricted to single finger identification within a surface area of less than 10 x 10mm. Isorg’s FoD module supports one- to four-finger authentication across the entire dimensions of the six-inch (152mm) smartphone display (or even larger). The module is very thin, less than 0.3mm thick, so integration into smartphones is made easy for OEMs, added the company.
In addition to the image sensor, the module includes optimised thin film optical filters developed in-house and driving electronics, as well as software from Isorg’ industrial partners covering the interface with smartphone OS and the matching algorithm. The scalable FoD is compatible with foldable displays, added the company.
Isorg’s four-finger authentication capability paves the way for secure smartphone mobile banking and payments, personal health monitoring and remote home control applications, including enhanced data protection for wearables, such as access control. By enabling more identification data to be captured with multiple fingers, it significantly reduces the risk of false finger identity theft, in addition to the ease of use by being able to place 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, aimed at meeting growing security needs in access control, border control and other identity access management areas, including mobile ID applications.
The live demo will take place at Eureka Park Tech West – Sands Expo, Level 1, Hall G booth #50463 at CES Las Vegas (7 to 10 January 2020)
