CrucialTec In-Display Fingerprint Sensor Patent

KoreaHerald Investor reports that CrucialTec has been granted a US patent for its in-display fingerprint solution which the company calls DFS:


The company is talks with some global clients to commercialize the fingerprint tech in the whole area of a smartwatch screen and a certain part of a smartphone display,” a CrucialTec official said. The newly patented technology is said to feature three thin film transistors for each electrode to pick up high-resolution images, compared to one for each electrode in the existing fingerprint scanner. That configuration is said to maximize the sensing capability while maintaining high transparency level of the components.

In spite of mentioning 3T technology, some of the company's recent patent applications keep talking about 1T pixels:


MobileIDWorld, BiometricUpdate: In-display fingerprint sensing solutions are gathering quite a lot of attention recently. Goodix presented its solution at MWC in Barcelona this year. Synaptics and OXi Technology have been reported developing a similar technology some time ago. Apple is rumored to integrate a similar sensor in its future iPhone displays.
