LG Innotek has developed a new way to integrate fingerprint sensors, removing the need for a button.
(CCM) — On Monday, LG Innotek announced that it has developed a fingerprint sensor that sits under the smartphone's display, rather than requiring a button. "Previous 'button type' modules required you to press a finger on a raised square or circular button for your fingerprint to be read exactly, so the sensor was usually mounted on the front, rear, or side buttons of a smartphone," explained LG. Instead, its module is inserted into the display via "a shallow furrow of 0.01 inches (0.3mm) thick on the lower backside of the cover glass." Because this sensor is under the glass, it is protected from direct danger of water damage or scratches; LG has incorporated a "proprietary adhesive" to attach the scanner and protect it from high impact damage. The new under-glass fingerprint module is also more accurate than its button-based counterparts. According to LG, the new module has a false acceptance rate of just 0.002 percent.
While LG believes that the demand for fingerprint recognition technology is on the rise, it did not reveal when this module might start appearing in devices. According to market research firm IHS, the demand for fingerprint sensors is set to more than triple in the next five years. In 2015, approximately 499 million fingerprint sensors were sold globally, and IHS predicts this to skyrocket to 1600 million units by 2020. An LG spokesperson told the Korea Times that the new module may be commercialized "within the year," though LG has not confirmed this statement.
