Abstract
A method for making an array substrate includes the following steps: forming a poly-silicon semiconductor layer on a substrate; forming a buffer layer on the substrate; depositing a first metal layer, and patterning the first metal layer to form gate electrodes for a driving TFT, a switch TFT, and a poly-silicon TFT; forming a first gate insulator layer; forming a second gate insulator layer; defining through holes passing through the buffer layer, the first gate insulator layer, and the second gate insulator layer to expose the poly-silicon semiconductor layer; depositing a metal oxide layer to form a first metal oxide semiconductor layer; and depositing a second metal layer to form source electrodes and drain electrodes for the driving TFT, the switch TFT, and the poly-silicon TFT.
