Abstract: An array substrate, a method for manufacturing an array substrate, and a display panel are provided. The array substrate includes: a base substrate; a thin film transistor on the base substrate; and a PIN diode on a side of the thin film transistor away from the base substrate, in a direction running away the base substrate from the thin film transistor, the PIN diode including a first electrical conduction type semiconductor layer and an intrinsic semiconductor layer and a second electrical conduction type semiconductor layer stacked in sequence, wherein a material from which the first electrical conduction type semiconductor layer is made includes one or more of following materials: metal oxide, metal sulfide, metal selenide, metal nitride, metal phosphide, or metal arsenide.

Abstract: An oxide thin film transistor includes an oxide active layer, a first loose layer and a first oxygen release layer. The first loose layer is at least disposed on a first surface of the oxide active layer perpendicular to a thickness direction of the oxide active layer, and is in contact with the oxide active layer. A material of the first loose layer includes a first inorganic oxide insulating material. The first oxygen release layer is disposed on a surface of the first loose layer facing away from the oxide active layer, and is in contact with the first loose layer. A material of the first oxygen release layer is a first oxygen-containing insulating material.
