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...
