[THE INVESTOR] Biometric solution developer CrucialTec said on April 12 that it has obtained a patent for a transparent sensor that allows smartphone touch screens to recognize fingerprints.

The patented technology, according to the firm, can reinforce the touch sensitivity on a specific part of a smartphone display to scan fingerprints. The new sensor is highly efficient to produce as the production process can be shared with an existing touch screen manufacturing line.

“The patented transparent sensor tech is part of CrucialTec’s ongoing project to develop an in-display fingerprint module, called the display fingerprint solution, or DFS, which started in 2012. The company will try to obtain patents for related technologies such as electrode structures, materials, operation of sensors and algorithms,” a CrucialTec official said.

The Pangyo-headquartered fingerprint module maker showcased the DFS at the Mobile World Congress trade show in Barcelona in February. The fingerprint module that can be placed under a smartphone display allows users to scan their fingerprints on the screen.

CrucialTec supplies fingerprint modules for smartphones made by global set makers such as LG Electronics, Huawei, Oppo and Vivo.
