Claim 16:
17. A display panel, comprising:
a display substrate, the display substrate including a plurality of pixel units; and
a touch layer and a fingerprint recognition layer disposed on the display substrate, wherein the touch layer includes one or more touch units, the fingerprint recognition layer includes one or more primary fingerprint recognition units, and each of the primary fingerprint recognition units includes NSFPS sub-fingerprint recognition units corresponding to Npixel ones of the pixel units, where NSFPS and Npixel are positive integers; and
wherein a distance PUFPS between adjacent ones of the primary fingerprint identification units satisfies PUFPS=Npixel×Ppixel or PUFPS=NSFPS×PSFPS, and a difference between Npixel×Ppixel and NSFPS×PSFPS is less than 25 micrometers, where Ppixel is a distance between adjacent ones of the pixel units, and PSFPS is a distance between adjacent ones of the sub-fingerprint recognition units.
