Abstract
An under-screen biometric identification apparatus and electronic device. The under-screen biometric identification apparatus includes an optical function layer, including a first linear polarizer and a first quarter-wave plate, wherein the first linear polarizer and the first quarter-wave plate are configured to be stacked; a biometric identification module, configured to perform biometric identification based on light transmitted to the biometric identification module via the optical function layer. The under-screen biometric identification apparatus could improve the performance of the under-screen biometric identification.
Claims20
An under-screen biometric identification apparatus, applicable to an electronic device having a display screen, the under-screen biometric identification apparatus comprising:
- an optical function layer, structured to be arranged under the display screen, the optical function layer comprising a first linear polarizer and a first quarter-wave plate;
