Abstract
A method for manufacturing an array substrate, an array substrate, and a fingerprint recognition device. The method includes: forming a plurality of polysilicon patterns on a substrate, the plurality of polysilicon patterns including a first polysilicon pattern for forming the PIN-type diode and a second polysilicon pattern for forming the transistor, each polysilicon pattern including a first sub-region, a second sub-region, and a third sub-region between the first sub-region and the second sub-region; using a first doping process to dope the first sub-region of the first polysilicon pattern and the first sub-region and the second sub-region of the second polysilicon pattern with one of P-type ions and N-type ions respectively; and using a second doping process to dope the second sub-region of the first polysilicon pattern with the other of P-type ions and N-type ions.
