In one aspect of the present invention, a method of making an OLED device comprises providing a substrate; a first electrode, a conductive bus line over the substrate and an organic electroluminescent media over the first electrode and over the conductive bus line. A laser that operating at a predetermined wavelength and is scanned over the conductive bus line in a predetermined direction so that the conductive bus line absorbs sufficient energy to cause the ablation a portion of the organic electroluminescent media over the conductive bus line thereby forming an opening in the organic electroluminescent media. The width of the laser beam in the predetermined direction is less than four times the width of the conductive bus line; and forming a second electrode over the organic electroluminescent media, the first electrode, and through the opening in the organic electroluminescent media.
