The manufacture method of the AMOLED back plate is: sequentially deposing a buffer layer (2), an amorphous silicon layer (2) on a substrate (1), and crystallizing and converting the amorphous silicon layer to be a polysilicon layer, and patterning the polysilicon layer, and then deposing a P type heavy doped micro silicon layer (P+uc-Si), and implementing a photo process to define a position of a channel (40), and etching the P type heavy doped micro silicon layer (P+uc-Si) to form a source/a drain (41), and thereafter, sequentially forming a gate isolation layer (5), a gate (61), an interlayer insulation layer (7), a metal source/a metal drain (81), a flat layer (9), an anode (10), a pixel definition layer (11) and a photo spacer (12); the source/the drain (41) and the gate (61) do not overlap in the horizontal direction and are mutually spaced. The method can improve the electrical property of the drive TFT to make the conductive current higher, and the leakage current lower, and diminish the image sticking for raising the display quality of the AMOLED."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Manufacture method of AMOLED back plate and structure thereof","description":"The present invention provides a manufacture method of an AMOLED back plate and a structure thereof.
