Abstract

The invention provides a quantum dot display substrate, a manufacturing method thereof and a display device, and belongs to the technical field of display. The quantum dot display substrate comprisesa black matrix pattern and a plurality of quantum dot light emitting units, wherein the quantum dot light emitting units are positioned in a light emitting region defined by the black matrix pattern,and is capable of emitting monochromatic light of different colors. The quantum dot display substrate also comprises a reflective barrier wall positioned between the adjacent quantum dot light emitting units, and the reflectivity of the reflective barrier wall to blue light is greater than a preset threshold. The quantum dot display substrate provided by the invention is characterized in that thecolor mixing caused by erroneous excitation between the quantum dot illuminating units can be prevented, and the utilization rate of blue light can be enhanced by the reflectivity of blue light in pixels, thereby greatly improving the color gamut and contrast of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Quantum Dots (QDs), also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 20 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure, which can emit fluorescence after being excited. [0003] Based on quantum effects, quantum dots have broad application prospects in solar cells, light-emitting devices, optical biomarkers and other fields. Quantum dots can be used to make quantum dot display substrates, which have the advantages of high color gamut and low power consumption. [0004] There are multiple quantum dot light-emitting units on the quantum dot display substrate, and the multiple quantum dot ...
