preparation example Construction
[0029] Embodiments of the present invention provide a method for preparing an electroluminescent display panel, such as figure 1 As shown, the preparation method may include the following steps:
[0030] S101, forming a pattern of an anode in each sub-pixel of the base substrate and forming a pattern of a pixel defining layer between each sub-pixel.
[0031] Specifically, a single patterning process is used to form the patterns of the anodes in the sub-pixels of the base substrate. Wherein, the material of the anode may include a transparent conductive material. Wherein, the transparent conductive material may include one or a combination of indium tin oxide (ITO), indium zinc oxide (IZO), carbon nanotubes, graphene, nano gold and nano silver, which is not limited herein.
[0032] A patterning process is used to form the graphics of the pixel defining layer between the sub-pixels.
[0033] S102. Using an inkjet printing process to spray ink and anti-solvent in each sub-pixe...
