Whiplash February 18 news, today, BYD Semiconductor Co., Ltd. applied for the "fingerprint recognition device, mobile terminal and fingerprint recognition device wake-up method" was authorized.
The abstract shows that the fingerprint recognition apparatus comprises a fingerprint recognition chip, a plurality of detection sub-regions disposed on top of the fingerprint recognition chip and a metal ring surrounding the fingerprint recognition chip. After the fingerprint recognition chip detects that the metal ring is touched and lasts for a preset time, it detects the number of detection sub-regions covered, and if the number is greater than the preset threshold, the fingerprint recognition scan is initiated. The device realizes two levels of wake-up when the fingerprint recognition scanning function is started, which avoids opening the fingerprint scanning function due to accidental touch, thereby reducing power consumption and improving user experience.
