摘要： 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.

摘要： In an array substrate of the present invention, only two insulating layers are arranged on a planarization layer. Compared with conventional techniques that require at least four insulating layers arranged on the planarization layer, a number of the insulating layers arranged on the planarization layer is reduced. Therefore, a number of photomasks is reduced in a manufacturing process of the array substrate, and the manufacturing process is simplified. The present invention also provides a manufacturing method of the array substrate, and a display panel.

摘要： 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.

摘要： A fingerprint collection device and a display panel are provided. The fingerprint collection device includes: a base substrate, a driving circuit layer, a first passivation layer, a photodiode, a second passivation layer, and an electrode layer. A first electrode portion is electrically connected to the photodiode through a second via. A second electrode portion is electrically connected to a first signal trace and a second signal trace through a third via and a fourth via to form a bridge structure. Since the third via, the fourth via, and the second via are formed in same process, one process can be saved.
