A fabrication method of an indium tin oxide (ITO) anode containing point
nickel for an organic light emitting diode (OLED) to selectively light
includes various processes of preparing an ITO substrate with an anode
having plural point grooves, of forming a nickel film on the anode, and
of grinding the nickel film to leave the point grooves fitted with
nickel. Therefore, the nickel spots of the ITO anode are lit up earlier
than the pure ITO anode when the OLED is turn on. Because the nickel
spots have a lower resistance, current can aggregate in these spots
collectively, reducing demerit of cross-talk happening often in a
conventional passive OLED panel circuit. The structure of the OLED
includes an ITO substrate with an anode provided point grooves deposited
with nickel, a hole transport layer on the anode, and an electron
transport layer on the hole transport layer.
