A process for the production of oled - pixel - device and the display device.

摘要

A method for the production of an organic light emitting diode - pixel, of an oled - pixel, wherein the oled - pixels at least a first sub-pixels, a second subpixel and a third subpixel, and the method for the production of the oled - pixel comprises:Producing an anode and a pixel boundary layer on a substrate, wherein the pixel boundary layer a first subpixel area in correspondence to the first sub-pixels, a second subpixel area in correspondence to the second subpixel, a third subpixel area in correspondence to the third subpixel and a pixel distance range, and wherein the first sub-pixels, the second subpixel and the third subpixel by means of the pixel distance region are separated from each other;Application of a first long-chain fatty acid esters layer on the pixel distance region, the second subpixel area and the third subpixel area;Application of a first light emitting layer on the first subpixel area and the first long-chain fatty acid esters layer;Etching of the substrate and the removal of the first long-chain fatty acid esters layer for the manufacture of a first light emitting raster;Application of a second long-chain fatty acid esters layer on the pixel distance region, the first light emitting grid and the third subpixel area;Application of a second light emitting layer on the second subpixel area and the second long-chain fatty acid esters layer;Etching of the substrate and removal of the second long-chain fatty acid esters layer for the manufacture of a second light emitting raster;Application of a third long-chain fatty acid esters layer on the pixel distance region, the first light emitting grid and the second light emitting grid;Application of a third light emitting layer on the third subpixel area and the third long-chain fatty acid esters layer;Etching of the substrate and removal of the third long-chain fatty acid esters layer for the manufacture of a third light emitting raster;Production of a cathode.
