LG Innotek Develops Under-Glass Fingerprint Sensor Module for Smartphones

LG Innotek developed an under-glass fingerprint sensor module that eliminates the need for a “button-type” sensor, freeing up a smartphone’s design, the company said in a Monday announcement. “With this module, the sensor is not exposed to the outside of the device,” so manufacturers can produce a “sleek designed” smartphone, it said. High-strength cover glass protects the sensor and prevents it from coming in direct contact with water or damage from scratches, it said. LG Innotek developed a “proprietary” adhesive to attach the sensor to the glass, it said. LG Innotek thinks the expansion of smartphone-based mobile payments will “dramatically” increase demand for fingerprint recognition technology, it said.
