A kind of 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 a quantum dot display panel. The preparation method comprises: preparing a red light quantum dot solution and a green light quantum dot solution whose external ligands are magnetic; A magnetic material covers the first region of the transparent substrate, and a second magnetic material with a second Curie point temperature covers the second region of the transparent substrate; the first region, the second region and the third region without deposition do not overlap each other , to obtain the magnetic deposition substrate; the magnetic deposition substrate is immersed in the red light quantum dot solution to obtain the red light quantum dot color film structure, and is immersed in the green light quantum dot solution to obtain the green light quantum dot color film structure and the quantum dot color film substrate; the quantum dot color film substrate is set in the blue light On the light emitting side of the backlight module, the blue light reflective layer is located on the side of the quantum dot color film substrate away from the blue light backlight module. The technical solution provided by the invention avoids the use of color filters, avoids the waste of blue light, optimizes the performance of quantum dots, and improves luminous efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of quantum dot display, 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 1-10 nm. Since electrons and holes are quantum confined, the continuous energy band structure becomes a discrete energy level structure, so the emission spectrum is very narrow (20 -30nm), high chromaticity, wide display color gamut, can greatly exceed the (US) National Television Standards Committee (National Television Standards Committee, NTSC) color gamut range (> 100%). Due to its special characteristics, quantum dots are gradually emerging as a new generation of luminescent materials in LED display applications. [0003] Quantum dot color film is a key component for display devices to achieve full color display with ultra-high color gamut....

AI Technical Summary

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
