Inkjet printing OLED display panel and manufacturing method for the same
Abstract:
An inkjet printing OLED display panel and manufacturing method are provided. The method includes sequentially forming a passivation layer and a planarization layer on thin-film transistors on a glass substrate, and the passivation layer covers the thin-film transistors; forming vias both at the passivation layer and the planarization layer; forming anodes on the planarization layer, and the anodes are electrically connected to the thin-film transistors through the vias; depositing a pixel definition layer on the planarization layer, and the pixel definition layer covers the anodes; using a half-tone mask to define a pattern of the pixel definition layer such that a region of the pixel definition layer located above the anodes forms a notch, and a height of the pixel definition layer located between the anodes is decreased; using an inkjet printing technology to form a light-emitting layer in the notch of the pixel definition layer.
