On February 21, the public data of The enterprise check showed that BYD Semiconductor Co., Ltd. patent for "wake-up method of fingerprint recognition device, mobile terminal and fingerprint recognition device" was authorized.
The patent 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 around 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.
In addition, it is worth mentioning that for many fingerprint recognition devices, many users have encountered the situation of fingerprint mistouching, fingerprint touch, will light up the screen, or unlock the device, and then will misoperate, causing themselves unchanged, or the consumption of equipment power waste.
The bydir fingerprint recognition patent, through the two-level wake-up method, is expected to completely avoid the occurrence of false touch and improve the experience.
