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

摘要

The present invention provides a process for the production of an oled - of the pixels and an oled - display - device. The oled - pixels comprises at least a first sub-pixels, a second subpixel and a third subpixel. The process for the production of the oled - pixel of: preparing an anode and a pixel boundary layer on a substrate; subsequently making at least a first light emitting raster, a second light emitting raster and a third light emitting raster by application of long-chain fatty acid esters of layers and of light-emitting layers on the corresponding regions of the pixel boundary layer and by use of the property that the long-chain fatty acid esters of layers and the light-emitting layers do not infiltration; and producing a cathode. The process for the production of the oled - display - apparatus comprising: production of oled - pixels on a first substrate; producing a second substrate; and gluing of the first substrate and of the second substrate by means of a frit. The process for the production of the oled - of the pixels and the oled - display - device avoid different disadvantages which occur when the light emitting layers are formed in the conventional vapor deposition, and they are for the production of fully color films suitable.
