Patent ID: 11157715

Abstract:
A photodetection apparatus includes a cover unit (5), and an optical adhesive film (4), an optical member (3) and a photodetection film (2) in that order disposed on the cover unit. The cover unit (5) includes a plurality of spaced-apart LED elements (521) each configured to be driven to emit an initial light. The initial lights emitted from the LED elements (521) are partially reflected from a cover top surface of the cover unit (5) and sequentially incident on the optical adhesive film (4) and optical member (3). The optical adhesive film (4) and the optical member (3) are configured to respectively filter out a portion of the partially reflected initial lights incident thereon to form a photodetection-film incident light entering the photodetection film (2) and convertible to an identification image data. A biometric identification method using the photodetection apparatus is also disclosed.
