Abstract
A manufacturing method for an inkjet printing AMOLED display panel is disclosed. The method includes steps of: manufacturing a TFT backplane, and manufacturing an anode on the TFT backplane; manufacturing a spacer layer for isolating the anode from a pixel definition layer on the anode; manufacturing a pixel definition layer on the TFT backplane, and the pixel definition layer covers the spacer layer; patterning the pixel definition layer to form a notch on the pixel definition layer in order to expose the spacer layer; etching the spacer layer below the notch by an etching solution; and forming an ink layer on the anode by an inkjet printing method. The invention can improve the cleanliness of the anode surface in the AMOLED display panel, reduce the residue, and make the printed light-emitting layer easier to spread evenly, prevent the AMOLED display panel from displaying abnormality.
