AI Technical Summary

Benefits of technology

This patented method allows for better performance over time without increasing costs because it includes protective measures such as sealing the quantum dot layer within an enclosed structure made of different materials like glass or plastic instead of just covering them completely. Additionally, this design prevents moisture ingress into certain areas while still allowing some airflow through. Overall, these technical improvements improve the overall quality and lifespan of quantum-dot films.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the performance and quality of displays with colored lights based on quantum dye technologies like fluorescence and quantum rod techniques. Current methods involve increasing emissive power without addressing issues related to poor thermal stability and moisture/water gas permeability. Additionally, current method involves applying multiple layers of different materials over time, making manufacturing processes complex and prone to defects during use.

Embodiment 1

[0051] Embodiment 1: quantum dot film structure

[0052] figure 1 A specific embodiment of the quantum dot film of the present invention is shown, which includes tightly bonded together and in figure 1 Substrate 1 , buffer layer 2 , quantum dot layer 3 , protective layer 4 , water-oxygen barrier layer 5 and cured layer 6 are arranged in sequence substantially along the direction from bottom to top. in:

[0053] The substrate 1 is made of glass, which has certain water and oxygen barrier properties. Of course, the substrate 1 can also use other materials with the same water and oxygen barrier properties, which can block water and oxygen and protect the quantum dot layer.

[0054] The buffer layer 2 is equivalent to a layer of adhesive, which is used to bond and fix the quantum dot layer 3 and the substrate 1 to increase the peeling force between the quantum dot layer 3 and the substrate 1 .

[0055]The quantum dot layer 3 is formed on the buffer layer 2. The quantum dots in ...

Embodiment 2

[0063] Embodiment 2: quantum dot film structure

[0064] image 3 Another specific embodiment of the quantum dot film of the present invention is shown. Its structure is similar to that of the first embodiment above. The only difference is that the substrate 1 in this embodiment is no longer made of glass, but a polymer material. layer (such as PET, etc.).

Embodiment 3

[0065] Embodiment 3: quantum dot film structure

[0066] Considering that the water and oxygen barrier effect of the substrate 1 formed by the polymer material layer in Example 2 is poor, the inventors designed another Figure 4 The quantum dot film structure shown is similar to the structure of the second embodiment above, and its substrate 1 also uses a flexible polymer material layer, the difference is that in this embodiment, the polymer material layer is away from the buffer layer 2 A second water-oxygen barrier layer 7 is provided on the side of the second water-oxygen barrier layer 7, and a second cured layer 8 is provided on the side of the second water-oxygen barrier layer 7 facing away from the polymer material layer. That is to say, in this embodiment, a flexible polymer material layer is used as the substrate, and a layer of water and oxygen barrier layer and a layer of curing layer are sequentially arranged at the bottom of the polymer material layer, so that it h...

Abstract

The invention discloses a quantum dot film and a preparation method thereof. The quantum dot film comprises a substrate; a quantum dot layer; a buffer layer which adheres and fixes the quantum dot layer and the substrate; a protective layer which is formed on the quantum dot layer and wraps the quantum dot layer so as to protect the quantum dot layer; a water oxygen blocking layer which is formed on the protective layer and wraps the protective layer; and a solidification layer which is formed on the water oxygen blocking layer and wraps the water oxygen blocking layer so as to protect the water oxygen blocking layer. According to the quantum dot film, the quantum dot layer and the water oxygen blocking layer are omnibearingly packaged and protected so as to have high structural stability and long service life.
