Title:
HEART RATE DETECTION MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/228197
Kind Code:
A1
Abstract:
A heart rate detection module (10) and an electronic device (20). The heart rate detection module (10) comprises a substrate (11) and a light source (12), light receivers (13), light shielding portions (14), and an optical film (15) that are provided on the substrate (11). Each light shielding portion (14) is provided between the light source (12) and each light receiver (13), such that the light source (12) and each light receiver (13) are optically isolated. The optical film (15) covers the light source (12), the light shielding portions (14), and the light receivers (13); the side of the optical film (15) facing the substrate (11) is provided with light filtration portions (150); when applying, the light filtration portions (150) can filter interference light emitted to the light receivers (13), such that the interference light received by the light receivers (13) is reduced, thereby increasing a signal-to-noise ratio of the heart rate detection module (10) so as to achieve relatively high heart rate detection accuracy of the electronic device (20).
