Abstract

The disclosure discloses a light source assembly, a backlight module and a display device and relates to the field of display technologies, and the light source assembly includes a printed circuit board, an LED chip, and a glass tube in which a quantum dot material is filled, wherein a concave groove, on the bottom of which the LED chip is arranged, is arranged on the surface of the printed circuit board, a part or all of the glass tube is accommodated in the concave groove, and the glass tube is fixed in the concave groove.

Claims (32)

1. A light source assembly, comprising:

a printed circuit board;

an LED chip; and

a glass tube in which a quantum dot material is filled, a surface of the printed circuit board sunken inward to form a concave groove having a bottom and sidewalls, the LED chip arranged on the bottom of the concave groove, a part or all of the glass tube accommodated in the concave groove, and the glass tube fixed on the sidewalls of the concave groove.

2. The light source assembly of claim 1 , wherein the glass tube is fixed on the sidewalls of the concave groove by a bracket.

3. The light source assembly of claim 2 , wherein the bracket is arranged between the glass tube and the sidewalls of the concave groove.

4. The light source assembly of claim 1 , wherein the glass tube is adhesively fixed on the sidewalls of the concave groove by an adhesive.

5. The light source assembly of claim 4 , wherein the adhesive is reflective white adhesive.

6. The light source assembly of claim 1 , wherein the concave groove comprises a first sub-concave groove and a second sub-concave groove, wherein the second sub-concave groove is arranged above and communicated with the first sub-concave groove, and a bottom area of the second sub-concave groove is larger than a bottom area of the first sub-concave groove, and the glass tube is accommodated in the second sub-concave groove.

7. The light source assembly of claim 6 , wherein the glass tube is fixed on sidewalls of the second sub-concave groove by a bracket, and the bracket is arranged between the glass tube and the sidewalls of the second sub-concave groove.

8. The light source assembly of claim 6 , wherein the glass tube is adhesively fixed on sidewalls of the second sub-concave groove by an adhesive, and the adhesive is arranged between the glass tube and the sidewalls of the second sub-concave groove.

9. The light source assembly of claim 2 , wherein the bracket is a reflective and thermally enduring plastic bracket with reflectivity larger than or equal to 93% and endurable temperature higher than or equal to 110 degrees centigrade.

10. A backlight module, comprising:

a light source assembly comprising:

a printed circuit board;

an LED chip; and

a glass tube in which a quantum dot material is filled, a surface of the printed circuit board sunken inward to form a concave groove having a bottom and sidewalls, the LED chip arranged on the bottom of the concave groove, a part or all of the glass tube accommodated in the concave groove, and the glass tube fixed on the sidewalls of the concave groove.

11. The backlight module of claim 10 , wherein the bracket is arranged between the glass tube and the sidewalls of the concave groove.

12. The backlight module of claim 10 , wherein the glass tube is fixed on the sidewalls of the concave groove by a bracket.

13. The backlight module of claim 12 , wherein the bracket is a reflective and thermally enduring plastic bracket with reflectivity larger than or equal to 93% and endurable temperature higher than or equal to 110 degrees centigrade.

14. The backlight module of claim 10 , wherein the glass tube is adhesively fixed on the sidewalls of the concave groove by an adhesive.

15. The backlight module of claim 14 , wherein the adhesive is reflective white adhesive.

16. The backlight module of claim 10 , wherein the concave groove comprises a first sub-concave groove and a second sub-concave groove, wherein the second sub-concave groove is arranged above and communicated with the first sub-concave groove, and a bottom area of the second sub-concave groove is larger than a bottom area of the first sub-concave groove, and the glass tube is accommodated in the second sub-concave groove.

17. A display device, comprising:

a backlight module comprising:

a light source assembly comprising:

a printed circuit board;

an LED chip; and

a glass tube in which a quantum dot material is filled, a surface of the printed circuit board sunken inward to form a concave groove having a bottom and sidewalls, the LED chip arranged on the bottom of the concave groove, a part or all of the glass tube accommodated in the concave groove, and the glass tube fixed on the sidewalls of the concave groove.

18. The display device of claim 17 , wherein the glass tube is fixed on the sidewalls of the concave groove by a bracket.

19. The display device of claim 17 , wherein the glass tube is adhesively fixed on the sidewalls of the concave groove by an adhesive.

20. The display device of claim 17 , wherein the concave groove comprises a first sub-concave groove and a second sub-concave groove, wherein the second sub-concave groove is arranged above and communicated with the first sub-concave groove, and a bottom area of the second sub-concave groove is larger than a bottom area of the first sub-concave groove, and the glass tube is accommodated in the second sub-concave groove.
