Abstract
A fingerprint detection apparatus and an electronic device are provided. The fingerprint detection apparatus is applied under a display screen to implement under-screen optical fingerprint identification, including: a fingerprint sensor; the fingerprint sensor includes: N groups of sub-pixels, where N is a positive integer greater than 1; and different groups of sub-pixels in the N groups of sub-pixels respectively receive light signals with different characteristics in light signals returned by reflection or scattering via a finger, and light signals received by each group of sub-pixels in the N groups of sub-pixels are used to form one pixel in a fingerprint image of the finger.
Claims19
A fingerprint detection apparatus, wherein the fingerprint detection apparatus is applied under a display screen to implement under-screen optical fingerprint identification, and the apparatus comprises:
- a fingerprint sensor;
- the fingerprint sensor comprises:
- N groups of sub-pixels, wherein N is a positive integer greater than 1;
- and
- different groups of sub-pixels in the N groups of sub-pixels respectively receive light signals in different directions in light signals returned by reflection or scattering via a finger, and light signals in the same direction received by each group of sub-pixels in the N groups of sub-pixels are used to form one pixel in a fingerprint image of the finger;
- wherein the N groups of sub-pixels comprise a first group of sub-pixels, a plurality of first sub-pixels in the first group of sub-pixels are not adjacent to each other, and the plurality of first sub-pixels in the first group of sub-pixels are adjacent to other sub-pixels in the N groups of sub-pixels other than the first group of sub-pixels.
An electronic device, comprising:
- a display screen and a fingerprint detection apparatus, wherein the fingerprint detection apparatus is disposed under the display screen, and the fingerprint detection apparatus comprises:
- a fingerprint sensor;
- the fingerprint sensor comprises:
- N groups of sub-pixels, wherein N is a positive integer greater than 1;
- and
- different groups of sub-pixels in the N groups of sub-pixels respectively receive light signals in different directions in light signals returned by reflection or scattering via a finger, and light signals in the same direction received by each group of sub-pixels in the N groups of sub-pixels are used to form one pixel in a fingerprint image of the finger;
- wherein the N groups of sub-pixels comprise a first group of sub-pixels, a plurality of first sub-pixels in the first group of sub-pixels are not adjacent to each other, and the plurality of first sub-pixels in the first group of sub-pixels are adjacent to other sub-pixels in the N groups of sub-pixels other than the first group of sub-pixels.
