For top-emitting OLED, the top electrode as light-emitting surface OLED must have good light transmission rate.Currently, top
What transmitting transparent electrode used is mostly the materials such as thin metal, ITO, IZO, wherein metal is since transmitance is poor, conduct after thinning
Broad-area electrode use be easy to cause resistance to increase, and is unfavorable for the exploitation of large-size device.ITO (Indium Tin Oxide, indium
Tin-oxide), the high material of transparencies such as IZO (Indium Zinc Oxide, indium-zinc oxide), the electric conductivity of itself
It is weaker than metal.Therefore in the related technology, using metal as auxiliary electrode, non-luminous region is produced on using the method for photoetching, is mentioned
The overall conductivity of high top emitting transparent electrode reaches the low-resistance effect of drop.But this photoetching technique needs complicated work
Skill, is related to multiple tracks mask plate and exposure process, and since it needs high temperature, photoresist the process characteristics such as to wash away, can be to OLED
The electroluminescence layer 30 of device damages, and is not suitable as volume production means.It is also existing that auxiliary electrode is made on encapsulation cover plate
There is one of technology to increase a kind of mode of electrode conductivuty, it can be to avoid being deposited in the first manufacture craft using this kind of mode
The problem of.But auxiliary electrode relies on encapsulation cover plate, and component cases thickness is caused to become larger, and is unfavorable for the thinning of display device.
