South Korea's CrucialTec has been awarded a patent for an in-display fingerprint solution in the US.As reported in The Investor, the solution, which the firm calls DFS, enables users to authenticate themselves by placing their finger on a smartphone screen. The components embedded in the DFS, including conducting electrodes, wires and transistors, are all transparent.The newspaper adds that the company is trying to deploy the fingerprint tech in wearable devices and smartphones as early as this year.”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 official explained to The Investor that the newly patented technology features 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 maximizes the sensing capability while maintaining high transparency level of the components.
