Abstract

The present disclosure discloses a backlight module and a method for assembling the same, and a display device. The backlight module includes a backplate and a light strip, wherein, on the backplate is provided a fixing structure, the fixing structure including a resilient press tab provided with a protrusion thereon projecting toward the surface of the backplate, and on the light strip is provided a hole which can be matched with the protrusion on the resilient press tab.

First claim

What is claimed is:

1. A backlight module comprising:
a backplate; and
a light strip, wherein a fixing structure is provided on the backplate, the fixing structure comprising a resilient press tab that includes a protrusion projecting toward a surface of the backplate, and wherein the light strip includes a hole configured to engage the protrusion on the resilient press tab;
wherein the fixing structure further comprises a root portion connected to the backplate, wherein one end of the resilient press tab is connected to the root portion and the other end of the resilient press tab is a free end; and
wherein the resilient press tab is parallel to the surface of the backplate, and wherein a height of a lower surface of the resilient press tab from an upper surface of the backplate is slightly larger than or equal to a thickness of the light strip.

2. A backlight module according to claim 1 , wherein the fixing structure comprises at least one row of fixing structures, each row of fixing structures comprising at least two fixing structures, and each row of fixing structures configured to secure a corresponding light strip.

3. A display device comprising:
a display panel; and
a backlight module according to claim 2 .

4. A backlight module according to claim 1 , wherein the fixing structure is formed by pressing.

5. A display device comprising:
a display panel; and
a backlight module according to claim 4 .

6. The backlight module according to claim 1 , wherein the protrusion is one of hemispherical, partially hemispherical, conical, and truncated conical.

7. A display device comprising:
a display panel; and
a backlight module according to claim 6 .

8. The backlight module according to claim 1 , wherein a diameter of a root portion of the protrusion is slightly larger than a diameter of the hole, and wherein a diameter of an end portion of the protrusion is slightly smaller than the diameter of the hole.

9. A display device comprising:
a display panel; and
a backlight module according to claim 8 .

10. The backlight module according to claim 1 , wherein a position of the protrusion on the resilient press tab is determined by a required tightness of the light strip and the backplate assembly, and wherein the greater the required tightness of the light strip and the backplate assembly, the closer the protrusion is to the root of the fixing structure.

11. A display device comprising:
a display panel; and
a backlight module according to claim 10 .

12. The backlight module according to claim 1 , wherein the hole is provided with a chamfer on a side facing the protrusion.

13. A display device comprising:
a display panel; and
a backlight module according to claim 12 .

14. The backlight module according to claim 1 , wherein a positioning stop wall is provided on the backplate, the positioning stop wall configured such that when the light strip abuts against the positioning stop wall, holes in the light strip are aligned with respective protrusions on a plurality of fixing structures along a direction of a length of the light strip.

15. A display device comprising:
a display panel; and
a backlight module according to claim 1 .

16. A backlight module comprising:
a backplate; and
a light strip, wherein a fixing structure is provided on the backplate, the fixing structure comprising a resilient press tab including a hole thereon, and wherein the light strip includes a protrusion configured to engage the hole in the resilient press tab;
wherein the fixing structure further comprises a root portion connected to the backplate, wherein one end of the resilient press tab is connected to the root portion and the other end of the resilient press tab is a free end; and
wherein the resilient press tab is parallel to the surface of the backplate, and wherein a height of a lower surface of the resilient press tab from an upper surface of the backplate is slightly larger than or equal to a thickness of the light strip.
