Abstract

The invention provides an array substrate, a manufacturing method of the array substrate and a display panel.The array substrate comprises a substrate, a polycrystalline silicon thin film and a plurality of first thin film transistors, wherein the polycrystalline silicon thin film is located on the substrate and comprises a plurality of first boundaries extending in the first direction, the first thin film transistors comprise channels formed in the polycrystalline silicon thin film, the length L of each channel in the second direction is equal to NP, N is an integer larger than 0, P is an interval between the adjacent first boundaries, and the second direction is perpendicular to the first direction.According to the array substrate, the manufacturing method of the array substrate and the display panel, the crystallization uniformity of the first thin film transistors is improved, and the displaying effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method of the array substrate and a display panel. Background technique [0002] Existing display panels use switching elements such as Thin Film Transistor (TFT, Thin Film Transistor) to control light emitting units such as OLED (Organic Light-Emitting Diode) and LCD (Liquid Crystal Display). However, in the fabrication of TFT elements in display panels, a polysilicon thin film used as a channel of the TFT element is usually formed on a substrate, so that the TFT element has a switching control effect. At present, the mainstream technology for preparing polysilicon thin films is excimer laser annealing technology (ELA, Excimer Laser Annealing). Excimer laser annealing technology uses a laser beam to scan the amorphous silicon layer to crystallize the amorphous silicon layer into a polysilicon film. However, when the excimer laser an...
