利用點狀鎳摻雜銦錫氧化物(ITO)陽極形成選擇性有機發光二極體(OLED)發光的結構及其方法

本專利是一種利用點狀鎳摻雜銦錫氧化物(ITO)陽極形成選擇性有機發光二極體(OLED)發光的結構及其方法,該方法包括有:提供一ITO基板,其有一陽極表面,其上形成有點狀槽;沉積Ni膜;及以一研磨法將該Ni膜回磨至前述之點狀槽,致該點狀槽外的Ni膜全被去除,留下Ni膜於點狀槽內,形成點狀Ni嵌入ITO膜;藉此,OLED元件被點亮時,其周遭純ITO陽極上之OLED元件尚未被點亮,此即所謂選擇性OLED發光效果。又,因點狀Ni嵌入ITO陽極有較低的電性阻抗,故電流集中於此電極內,而可衍生出降低傳統被動式OLED面板電路上交互干擾(cross-talk)的問題。 The objective of this invention is to offer a fabrication method of an ITO anode containing point nickel for selectively lighting an OLED device. The process goes by: (a) preparing an ITO substrate provided with an anode having plural point grooves, (b) depositing a nickel film on the anode, and (c) grinding off the nickel film except those filled in the point grooves. This invention also offers a structure of OLED to selectively light, at least including a substrate provided with an anode having plural point grooves deposited with nickel, a hole transport layer formed on the anode. The point grooves deposited with nickel on the ITO anode are to have a lower resistance, allowing current to aggregate in them, able to reduce cross-talk happening often in a conventional passive OLED panel circuit.
