摘要： A method of forming an array substrate, the array substrate and a display device are provided. The method of forming the array substrate includes: in a case that a display unit is formed on one of two opposite surfaces of a base substrate and a driving circuit is formed on the other of the two opposite surfaces of the base substrate, performing a roughening treatment on edge regions of the two opposite surfaces of the base substrate and a side surface of the base substrate connecting the edge regions of the two opposite surfaces, to form a roughened region; and forming, at the roughened region, a metal wiring connecting a signal input terminal of the display unit and a signal output terminal of the driving circuit.

摘要： To construct a display substrate, a first metal connection part is formed on a first surface of a base substrate, extending to a first surface edge region, and a second metal connection part is formed on a second surface of the base substrate opposite to the first surface, extending to a second surface edge region. A flexible film formed on the first surface is patterned to expose a portion of the first surface edge region, aligned with the first metal connection part. A portion of the base substrate covered by the first surface edge region is removed. A portion of the flexible film in the first surface edge region is bent to cover at least a portion of a sidewall of the base substrate. A sidewall metal connection part is formed to electrically connect the first and second metal connection parts, and the flexible film is removed.

摘要： A method of manufacturing a low temperature polycrystalline silicon thin film and a thin film transistor, a thin film transistor, a display panel and a display device are provided. The method includes: forming an amorphous silicon thin film (01) on a substrate (1); forming a pattern of a silicon oxide thin film (02) covering the amorphous silicon thin film (01), a thickness of the silicon oxide thin film (02) located at a preset region being larger than that of the silicon oxide thin film (02) located at other regions; and irradiating the silicon oxide thin film (02) by using excimer laser to allow the amorphous silicon thin film (01) forming an initial polycrystalline silicon thin film (04), the initial polycrystalline silicon thin film (04) located at the preset region being a target low temperature polycrystalline silicon thin film (05). The polycrystalline silicon thin film has more uniform crystal size.
