Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a polysilicon array substrate, a polysilicon array substrate and a display panel. Background technique [0002] At present, with the rapid development of electronic equipment, more and more display panels are used in electronic equipment. The display panel includes an array substrate and a color filter substrate, and the array substrate is one of the important components of the display panel. According to the material of the thin film transistors in the array substrate, the array substrate can be divided into a polysilicon array substrate and an amorphous silicon array substrate. The electron mobility of the polysilicon array substrate is much greater than that of the amorphous silicon array substrate. The greater advantage is that polysilicon array substrates are often obtained by low-temperature polysilicon technology. Low-temperature polysilicon tec...
