Abstract

An organic LED includes a transparency electrode, an organic luminescent layer, an antireflection and an auxiliary electrode. Said Organic luminescent layer is located between transparency electrode and antireflection electrode, antireflection electrode including first conducting layer, a second conducting layer and a nonmetal layer, said first conducting layer located between organic luminescent layer and nonmetal layer, said nonmetal layer located between first conducting layer and second conducting layer, auxiliary electrode penetration nonmetal layer and connecting said first conducting layer to second conducting layer. Above-mentioned organic LED can be used in an organic electro photoluminescence display.

Description

technical field [0001] The invention relates to an organic light-emitting diode and its display, in particular to a low-resistance organic light-emitting diode and its display. Background technique [0002] Organic light-emitting diodes have characteristics such as low operating voltage and high luminous efficiency, so they are suitable as light-emitting elements for flat-panel displays. The basic structure of an organic light-emitting diode includes a plurality of stacked organic layers sandwiched between two electrodes. In single-sided flat-panel displays, OLEDs have a reflective electrode and a transparent electrode. The reflective electrode is generally a metal material with a low work function, and serves as a cathode for electron injection. Since part of the light generated by the OLED is reflected by the reflective electrode and guided to the transparent electrode, the reflective electrode also helps to enhance brightness. [0003] However, the ambient light enteri...
