Abstract

The invention relates to a nano quantum dot light-emitting diode based on self-assembled submicron spheres and a method. The nano quantum dot light-emitting diode comprises a substrate, an anode layer, an insulating layer pixel Bank array, a hole injection layer, a hole transport layer, a quantum dot light-emitting layer, an electron transport layer and a cathode layer which are sequentially arranged from bottom to top. According to the nano quantum dot light-emitting diode based on the self-assembled submicron spheres, the problem that an existing quantum dot light emitting diode is not small enough and not dense enough is solved.

Description

technical field [0001] The invention relates to the field of preparation of quantum dot light-emitting diodes, in particular to a nano-quantum dot light-emitting diode based on self-assembled submicron spheres and a method thereof. Background technique [0002] Quantum dots have attracted the attention of many researchers because of their low cost and high energy efficiency. In addition, due to their high color purity and compatibility with printing process preparation, quantum dots have become a popular material for new light-emitting diodes. This will be One of the important research directions in the field of display in the future. [0003] Today's high-PPI display devices are developing rapidly. The higher the PPI value, the higher the density of the display, the better the image quality, and it also lays a solid foundation for 3D display. However, in order to obtain a higher PPI, the pixels need to be as small and dense as possible. This problem needs to be solved urge...
