Abstract: A display panel is disclosed. The display panel includes a photosensitive device. The photosensitive device includes a barrier component and a second active pattern. The second active pattern includes a second lightly-doped part, a second intrinsic part surrounding the second lightly-doped part, and a second heavily-doped part surrounding the second intrinsic part. In a film thickness direction, the barrier component overlaps the second intrinsic part. A dark current of the photosensitive device is reduced by the second intrinsic part, thereby improving sensitivity.

Abstract: A photo sensor, a manufacturing method thereof, and a display panel are disclosed. By an ion implantation method forming an N-type region and a P-type region on a surface of polycrystalline silicon in a same layer respectively, compatibility with an ion implantation process is ensured, while covering a layer of an amorphous silicon photosensitive layer on the polycrystalline silicon enhances light absorption ability and can increase photo-generated electron-hole pairs. Furthermore, built-in electric fields exist on a horizontal direction and a vertical direction, which can more effectively separate the electron-hole pairs to enhance photo-generated electric current to improve accuracy of fingerprint recognition.
