  • Methods of manufacturing OLED pixel and display device
    Patent number: 9048461
    Abstract: A method of manufacturing an Organic Light Emitting Diode (OLED) pixel is disclosed. The method includes forming an anode and forming a pixel definition layer. The pixel definition layer includes a first sub-pixel area, a second sub-pixel area, a third sub-pixel area corresponding to the third sub-pixel, and a pixel spacing area. The first sub-pixel, the second sub-pixel and the third sub-pixel are separated from each other by the pixel spacing area. The method also includes coating a long-chain fatty acid ester layers on the pixel spacing area, the second sub-pixel area, and the third sub-pixel area, coating light emitting layers on the sub-pixel areas and on the long-chain fatty acid ester layers, and ashing the substrate and removing the long-chain fatty acid ester layers to form light emitting patterns. The method also includes forming a cathode.
