Patent ID: 7919352

Claim:
A method of making an OLED device, comprising: a) providing a substrate and a first electrode and a conductive bus line over the substrate; b) providing organic electroluminescent media over the first electrode and over the conductive bus line; and c) scanning a laser that operates at a predetermined wavelength 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 conductive bus line in the predetermined direction being determined less than four times the width of the laser beam; and forming a second electrode over the organic electroluminescent media, the first electrode, and through the opening in the organic electroluminescent media so as to provide electrical connection between the second electrode and the conductive bus line.
