Claim 0:
1. A method of preparing an organic light emitting diode (OLED) display panel, comprising steps of:
providing a base substrate;
sequentially forming an array layer and a planarization layer on the base substrate;
forming a conductive layer on the planarization layer and patterning the conductive layer to form anodes;
forming the pixel definition layer further comprises steps of: preparing a red photoresist material on the anodes to form a first organic photoresist layer, and patterning the first organic photoresist layer to form a pixel definition layer located between the anodes adjacent to each other;
using a plasma to fluorinate a surface of the pixel definition layer to form a hydrophobic layer on the surface of the pixel definition layer; and
sequentially forming a luminescent layer, a cathode, and an encapsulation layer on the anodes.
