a Schematic of the intermediate electrode patterning process and photographs of real device images, for each step. b Side view and c tilted top view of scanning electron microscope images of the indium zinc oxide (IZO) layer, after patterning. Scale bar, 1 μm. d Photographic images of the blue organic light-emitting diode (OLED), with various applied voltages, after second IZO anode patterning by photolithography process. e Optical microscope images of fine-patterned second anode with 10 μm linewidths on the first OLED. Scale bar, 100 μm. f Blue, green, and red OLED unit luminous images, with 10-μm-patterned electrodes. Scale bar, 100 μm.
