Abstract
A method for fabricating a display panel includes: forming a plurality of N-type doped amorphous silicon structures on a substrate; forming an amorphous silicon layer covering the N-type doped amorphous silicon structures and the substrate; blue laser annealing the amorphous silicon layer and the N-type doped amorphous silicon structures, so that the N-type doped amorphous silicon structures are converted into N-type heavily doped polysilicon structures, a part of the amorphous silicon layer in contact with one of the N-type doped amorphous silicon structures and located between two adjacent N-type doped amorphous silicon structures is converted into an N-type lightly doped polysilicon structure, and other parts of the amorphous silicon layer are converted into a polysilicon layer; and patterning the polysilicon layer to form a semiconductor layer.
