Preparation method of quantum dot display panel and quantum dot display panel

Abstract

The invention provides a preparation method of a quantum dot display panel and the quantum dot display panel. The preparation method comprises the following steps of preparing a red light quantum dot solution and a green light quantum dot solution of which external ligands are magnetic, preparing a first magnetic material with a first curie point temperature to cover the first area of the transparent substrate, and preparing a second magnetic material with a second curie point temperature to cover the second area of the transparent substrate, wherein the first area, the second area and the non-deposited third area are not overlapped with one another to obtain a magnetic deposition substrate, immersing the magnetic deposition substrate into a red light quantum dot solution to obtain a red light quantum dot color film structure, and immersing the magnetic deposition substrate into a green light quantum dot solution to obtain a green light quantum dot color film structure and a quantum dot color film substrate, arranging the quantum dot color film substrate on the light emitting side of the blue light backlight module, and arranging the blue light reflecting layer on the side, deviating from the blue light backlight module, of the quantum dot color film substrate. According to the technical scheme provided by the invention, the use of a color filter is avoided, blue light waste is avoided, the quantum dot performance can be optimized, and the light emitting efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of quantum dot display technology, and in particular to a method for preparing a quantum dot display panel and a quantum dot display panel. Background technique [0002] The particle size of quantum dot (Quantum Dot, QD) materials is generally between 1-10nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure, so the luminescence spectrum is very narrow (20 -30nm), high chroma purity and wide display color gamut, which can greatly exceed the color gamut range (>100%) of the (National Television Standards Committee, NTSC) (US) National Television Standards Committee (NTSC). Due to its special characteristics, quantum dots, as a new generation of luminescent materials, are gradually emerging in LED display applications. [0003] Quantum dot color film is a key component for display devices to achieve ultra-high color ga...

Problems solved by technology

However, this solution has the following problems: 1) It is necessary to use color filters to filter the red, green, and blue light after color conversion, and its luminous efficiency is extremely low; 2) the red and green quantum dots are directly mixed, and the The two kinds of quantum dots will affect each other during the preparation and use, resulting in performance degradation and poor reliability of the diaphragm
