[0002] Face recognition is a biometric technology for identity recognition based on face feature information. Due to its convenience and recognition accuracy, it has been widely applied in various industries, such as the intelligent lock industry.

[0003] In the traditional field of face recognition, when face recognition is performed, the user needs to face the face recognition module. However, the components facing the user of the face recognition module are basically sensor modules such as cameras. Such sensor modules often give people a strong mechanical cold feeling. Therefore, in order to improve the user experience, a color screen display technology such as a display screen is often added to the face recognition system, so that the user's facial features or interactive effects such as light pattern and color can be displayed during face recognition, thereby improving the user experience.
