Abstract

The invention relates to an organic light emitting diode (LED) and a manufacturing method thereof. The organic LED comprises an insulation substrate, an anode, a hole implanted layer, a hole transfer layer and an organic emitting layer; the anode, the hole implanted layer, the hole transfer layer and the organic emitting layer are arranged on the insulation substrate in sequence; wherein, the anode is provided with fluorinion. The organic LED has better hole implanting effect.

Description

technical field [0001] The invention relates to an organic light emitting diode (Organic Light Emitting Diode, OLED) and a manufacturing method thereof. Background technique [0002] In recent years, organic light-emitting diodes have attracted the attention of the industry due to their unique advantages, such as simple manufacturing process, low power consumption, rich colors, suitable for flexible substrates and large-area displays. [0003] see figure 1 , is a cross-sectional view of a prior art organic light emitting diode. The organic light emitting diode 10 generally includes a substrate 11, an anode 12 stacked on the substrate 11 from bottom to top, a hole injection layer (Hole Injection Layer, HIL) 13, a hole transport layer (Hole Transfer Layer, HTL) 14 , an organic light emitting layer 15 , an electron transfer layer (Electron Transfer Layer, ETL) 16 , an electron injection layer (Electron Injection Layer, EIL) 17 and a cathode 18 . [0004] The working principl...
