Abstract

The invention discloses an organic light emitting diode which is used for increasing the light emitting efficiency of the organic light emitting diode. The organic light emitting diode comprises an upper substrate, a lower substrate, an electronic transmission layer, a hole transmission layer and a light emitting layer, wherein the electronic transmission layer and / or the hole transmission layer are perovskite-organic inorganic hybrid layers.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an organic light emitting diode. Background technique [0002] In the field of organic light emitting technology, the light emitting device is an organic light emitting diode (Organic Light Emitting Diode, OLED). [0003] The structure of OLED mainly includes: functional layers such as anode, hole transport layer, organic light-emitting layer, electron transport layer and cathode. [0004] Wherein, each functional layer in the OLED structure will affect the luminous efficiency of the OLED. For example, when the carrier mobility of the electron transport layer and the hole transport layer is high, the luminous efficiency of the OLED is high. [0005] In the prior art, the electron transport layer and the hole transport layer of the OLED are both organic layers, and the carrier mobility is low, so the luminous efficiency of the OLED is low. At present, the luminous efficiency o...
