  • Publication number: 20220350114
    Abstract: An optical lens system includes two lens elements which are, in order from an object side to an image side along an optical path: a first lens element and a second lens element. Each of the two lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one of the object-side surface and the image-side surface of at least one lens element of the optical lens system is aspheric. A total number of the lens elements in the optical lens system is two.

  • Publication number: 20220286662
    Abstract: A head-mounted device includes a plurality of front camera modules, a display device, an in-display camera module and an image-processing unit. The front camera modules include a first camera module and a second camera module that are respectively disposed at the left and right sides of the head-mounted device. The in-display camera module is disposed within the boundary of the display device. The image-processing unit is in communication connection with the front camera modules and the display device. The display device and the in-display camera module face a user side of the head-mounted device.

  • Publication number: 20220270391
    Abstract: An optical fingerprint identification system includes a cover, a light emitting layer, an optical layer, an image sensor and a base that are sequentially disposed from top to bottom. The cover has a fingerprint contact surface on top. The image sensor has an image surface. The optical layer includes a first array layer and a second array layer, and the first array layer is stacked on top of the second array layer. The first array layer and the second array layer respectively include a plurality of first array lens elements and a plurality of second array lens elements respectively arranged at equal intervals in a first direction. Each of the first array lens elements and a corresponding second array lens element of the second array layer are coaxial along an optical axis and form an imaging unit.

  • Patent number: 11373433
    Abstract: An optical fingerprint identification system includes a base, a photo sensor, a light emitting layer and a cover. The photo sensor is disposed on the base. The light emitting layer is disposed above the photo sensor, and the light emitting layer includes a light emitting element. The cover is disposed above the light emitting layer. The optical fingerprint identification system further includes a condenser unit and a light receiving element between the photo sensor and the cover. The condenser unit is disposed above the photo sensor. The light receiving element is disposed above the condenser unit. The light emitting element is disposed away from the photo sensor, the condenser unit and the light receiving element in a sideway direction that is different from a stack direction of the optical fingerprint identification system.
