초록
We fabricated blue fluorescent organic light-emitting diodes (OLEDs) by using a laser patterned ITO anode. An indium tin oxide (ITO) layer was defined directly with an infrared laser system (wavelength = 1064 nm), which was carried out at an optimum laser focal position, 1 W of laser power and 500 m/s of laser scanning speed. As a result, the problems with the laser patterning method, such as a shoulder at the ITO/glass edge, crack on the surface, and ITO debris were minimized. Moreover, we found that the OLED with laser patterned ITO showed almost similar electrical and optical properties to that of ITO that was patterned by photo-lithography.
