Claim:
1. A method of manufacturing a white organic light emitting diode (WOLED) back panel, comprising steps of: forming a pattern of a color filter layer on a substrate; exposing the pattern of the color filter layer by halftone exposure so as to form a groove structure in the pattern of the color filter layer; forming a pattern of a resin material layer on a surface of the substrate formed with the groove structure, and heavily doping a partial region of the resin material layer so as to form a heavily doped part having a conductivity, wherein the heavily doped partial region of the resin material layer corresponds to a pixel electrode region, a via region, and a connection region between the pixel electrode region and the via region, and other regions, which are not heavily doped, of the resin material are located in adjacent pixel units and have no conductivity; and forming an organic light-emitting layer and a cathode in order on a surface of the substrate after heavily doping the partial region of the resin material layer.
