the fingerprint sensor comprises: N groups of sub-pixels, wherein N is a positive integer greater than 1, the N groups of sub-pixels are arranged regularly in an array; and different groups of sub-pixels in the N groups of sub-pixels respectively receive light signals in different directions in light signals emitted by the display screen to a finger and returned by reflection or scattering via the 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; wherein the same group of sub-pixels in the N groups of sub-pixels are used to receive light signals in the same direction; each group of sub-pixels in the N groups of sub-pixels comprises a plurality of sub-pixels, and a sum of a plurality of light signals received by the plurality of sub-pixels is used to form one pixel in the fingerprint image of the finger; 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, 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 and each group of sub-pixels in the N groups of sub-pixels is arranged in the same manner in the N groups of sub-pixels; wherein the fingerprint detection apparatus further comprises: an optical component, the optical component comprises a micro-lens array and at least one light shielding layer; the micro-lens array is configured to be disposed under the display screen and includes a plurality of micro-lenses; the at least one light shielding layer is disposed under the micro-lens array and provided with a plurality of light directing channels corresponding to each micro-lens of the plurality of micro-lenses; and an optical sensing pixel array comprises the N groups of sub-pixels and is disposed under the at least one light shielding layer, and one sub-pixel is disposed under each of the plurality of light directing channels corresponding to the each micro-lens; light directing channels corresponding to different groups of sub-pixels in the N groups of sub-pixels have different directions, and light directing channels corresponding to the same group of sub-pixels in the N groups of sub-pixels have the same direction, and light signals passing through light directing channels in the same direction have the same direction. the fingerprint sensor comprises: N groups of sub-pixels, wherein N is a positive integer greater than 1, the N groups of sub-pixels are arranged regularly in an array;
