While increasing resolution remains a major trend within the display industry - such as 4K displays - there is also convergence towards POL-less (polarizer-less) technology. As a direct consequence of this trend, the lower display transmittance means traditional CIS (CMOS Image Sensor) fingerprint sensing technology is encountering a growing number of performance issues. The high efficiency of Isorg’s OPD technology, one of its key strengths, allows it to deliver much better levels of performance even under challenging system requirements.
Another key advantage, according to Isorg, is that its modules are thin - under 300µm. This permits smartphone makers to provide more space to integrate the battery and other components, compared to competitive sensor solutions.
High-end smartphones with curved displays or even foldable smartphones remain compatible with Isorg’s modules that can also be manufactured on flexible substrates.
“Over the course of the past few months, the teams of both Isorg and Precise Biometrics have engaged in developing solutions for smartphone OEMs and display makers to build next generation products. Improved integration of sensor and display capabilities will allow for new user experiences. Precise’s software competency complements our OPD technology stack and is instrumental in providing optimal biometric performance in line with current and future customer requirements,” said Dieter May, CEO of Isorg.
Due to the organic image sensor technology, Isorg has developed large-area fingerprint modules that are commercially available in different sizes from 20x30mm² up to full-display versions.
The complete module not only contains the organic image sensor, but also the necessary optical layers, in addition to its proprietary ASIC ReadOut IC (ROIC). Full-display modules create an enhanced user-experience, allowing authentication by applying the fingertip in any position across the entire screen and, in addition, also allows for multi-finger authentication, which significantly increases the level of security.
Isorg is working on simplifying integration for smartphone makers and is working with Precise Biometrics to take advantage of the company’s expertise in fingerprint development and optimisation algorithms to bring a solution to the mobile market.
This collaboration will mainly focus on image processing optimisation, taking into account the specifics of Isorg’s hardware performance, and enhancing matching quality by fine tuning Precise’s algorithms and integrating anti-spoofing features.
This cost-efficient solution is targeting major smartphone OEMs. Thanks to advanced discussions already held with them and an established supply-chain to scale production volume rapidly, Isorg said that it was confident of seeing a significant product ramp-up in the next 9-15 months.
