Abstract
The present invention discloses a WOLED back panel and a method of manufacturing the same. The method comprises: 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; the heavily doped partial region of the resin material layer corresponding to a pixel electrode region, a via region, and a connection region between the pixel electrode region and the via region; 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. The production cost is reduced in the present invention by forming a groove structure in the color filter layer instead of manufacturing a conventional pixel defining layer.
