Abstract

A QD glass cell includes a glass cell and QD fluorescent powder material. The glass cell includes a receiving chamber, and the QD fluorescent powder being encapsulated within the receiving chamber. A manufacturing method of the QD glass cell includes: S 101 : manufacturing a glass cell comprising a receiving chamber, and the glass cell comprising an injection port transmitting fluid into the receiving chamber; S 102 : manufacturing fluid QD fluorescent powder material; S 103 : filling the fluid QD fluorescent powder material into the receiving chamber via the injection port; S 104 : applying a curing process to the fluid QD fluorescent powder material within the receiving chamber; and S 105 : sealing the injection port by hot melting to obtain the QD glass cell. In addition, the above QD glass cell may be applied to LED light source.

First claim

What is claimed is:

1. A manufacturing method of a quantum dot (QD) glass cell, comprising:
S 101 : manufacturing a glass cell comprising a receiving chamber, and the glass cell comprising an injection port transmitting fluid into the receiving chamber;
S 102 : manufacturing a QD fluorescent powder material that is in a fluid form and comprises a gel material, which comprises one of an ultraviolet curable adhesive and an infrared curable adhesive, and QD fluorescent powder mixed with the gel material;
S 103 : filling the QD fluorescent powder material into the receiving chamber via the injection port;
S 104 : applying a curing process to the QD fluorescent powder material within the receiving chamber; and
S 105 : sealing the injection port by hot melting to obtain the QD glass cell.

2. The manufacturing method of the QD glass cell as claimed in claim 1 , wherein in step S 104 , the curing process comprises application of ultraviolet light or infrared light.

3. The manufacturing method of the QD glass cell as claimed in claim 1 , wherein a thickness of a wall of the QD glass cell is in a range between 0.1 mm and 0.7 mm.

4. The manufacturing method of the QD glass cell as claimed in claim 1 , wherein a weight percentage of the QD fluorescent powder within the QD fluorescent powder material is in a range between 1% and 20%.

5. The manufacturing method of the QD glass cell as claimed in claim 1 , wherein the QD fluorescent powder comprises one of CdSe/ZnSe, CdSe/ZnS, CdS/ZnS, CdS/HgS, CdSe/ZnS/CdS, CdSe/CdS/ZnS, InP/CdS, CuInS and graphene xxide QDs.
