Problems solved by technology
[0002] With the continuous development of communication equipment, the development speed of electronic equipment is also changing with each passing day. For example, mobile phones have developed from the previous ones with only basic communication functions to the current smart phones. In the existing smart phones, in order to meet the needs of larger screens Requirements, when performing fingerprint identification, the previous contact key identification has been developed into a non-key identification method, but the existing non-key identification method, when performing fingerprint identification, is likely to cause high power consumption during fingerprint identification
