Title:
BIOMETRIC SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/052663
Kind Code:
A1
Abstract:
A biometric sensing device. The device at least comprises: a digital light-emitting module comprising a first region and a second region, wherein the first region emits incident light; and a sensing module disposed under the digital light-emitting module, wherein in a first mode, the second region does not emit light having the same wavelength as that of the incident light, such that the digital light-emitting module provides an imperfect light field to illuminate an object above the digital light-emitting module, and light generated when the imperfect light field is reflected by the object is received by the sensing module.
