Abstract

Disclosed is a display apparatus. The display apparatus includes: a display panel and a backlight module; where the backlight module includes: a back plane including a plane portion and an inclined portion surrounding the plane portion, where the inclined portion inclines toward a light emitting side of the backlight module, and the inclined portion and the plane portion are arranged at a configured angle; a light board, arranged on the plane portion of the back plane; a split reflector plate, including a main reflector plate and side reflector plates; where the main reflector plate is arranged on a side of the light board facing away from the back plane, the side reflector plates are arranged on a side of the inclined portion of the back plane facing the light board, and splicing positions of the plurality of side reflector plates do not overlap with corner positions of the inclined portion.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display panel, configured to display images;
a backlight module, arranged on a light-incident side of the display panel and configured to provide backlight;
wherein the backlight module comprises:
a back plane comprising a plane portion and an inclined portion surrounding the plane portion, wherein the inclined portion inclines toward a light emitting side of the backlight module, and the inclined portion and the plane portion are arranged at a configured angle;
a light board, arranged on the plane portion of the back plane and configured to provide backlight to the display panel;
a split reflector plate, comprising a main reflector plate and a plurality of side reflector plates; wherein the main reflector plate is arranged on a side of the light board facing away from the back plane, the plurality of side reflector plates are arranged on a side of the inclined portion of the back plane facing the light board, and splicing positions of the plurality of side reflector plates do not overlap with corner positions of the inclined portion.

2. The display apparatus according to claim 1 , wherein the backlight module comprises a plurality of light boards and a plurality of main reflector plates; and
the main reflector plates are mounted to the light boards in one-to-one correspondence.

3. The display apparatus according to claim 2 , wherein a size of a main reflector plate among the plurality of main reflector plates is larger than a size of a corresponding light board among the plurality of light boards;
a gap with a set value is arranged between adjacent light boards among the plurality of light boards, and the gap is completely covered by a corresponding main reflector plate among the plurality of main reflector plates.

4. The display apparatus according to claim 3 , wherein there is an overlapping area between adjacent main reflector plates among the plurality of main reflector plates.

5. The display apparatus according to claim 4 , wherein the overlapping area is located in the gap, and the overlapping area and one or more light boards among the plurality of light boards do not overlap with each other.

6. The display apparatus according to claim 1 , wherein the plurality of side reflector plates comprise: a sky-side reflector plate, a ground-side reflector plate, a left reflector plate and a right reflector plate;
the inclined portion of the back plane comprises: a sky-side inclined portion, a ground-side inclined portion, a left inclined portion and a right inclined portion;
the sky-side reflector plate covers the sky-side inclined portion, and two ends of the sky-side reflector plate extend to the left inclined portion and the right inclined portion respectively;
the ground-side reflector plate covers the ground-side inclined portion, and two ends of the ground-side reflector plate extend to the left inclined portion and the right inclined portion respectively.

7. The display apparatus according to claim 6 , wherein the back plane further comprises a bent portion in connection with a side of the inclined portion away from the plane portion, the bent portion is parallel with the plane portion, and the plurality of side reflector plate further covers the bent portion;
the bent portion in connection with the ground-side inclined portion is provided with a fine positioning point convex hull and a coarse positioning point convex hull;
a side of the ground-side reflector plate away from the plane portion has a fine positioning clamping slot matching with the fine positioning point convex hull and a coarse positioning clamping slot matching with the coarse positioning point convex hull.

8. The display apparatus according to claim 6 , wherein a side of the sky-side inclined portion adjacent to the plane portion has a dent alignment mark line, and a side of the sky-side reflector plate adjacent to the plane portion has an alignment tangent line matching with the dent alignment mark line;
an edge of the sky-side inclined portion adjacent to the plane portion has a positioning groove, and an edge of the sky-side reflector plate adjacent to the plane portion has a positioning protrusion matching with the positioning groove of the sky-side inclined portion.

9. The display apparatus according to claim 6 , wherein an edge of the left inclined portion adjacent to the plane portion has a positioning groove, and an edge of the left reflector plate adjacent to the plane portion has a positioning protrusion matching with the positioning groove of the left inclined portion;
an edge of the right inclined portion adjacent to the plane portion has a positioning groove, and an edge of the right reflector plate adjacent to the plane portion has a positioning protrusion matching with the positioning groove of the right inclined portion;
two ends of the sky-side reflector plate close to the left reflector plate and close to the right reflector plate are respectively provided with edge alignment marks for locating edge positions of the left reflector plate and edge positions of the right reflector plate.

10. The display apparatus according to claim 9 , wherein adjacent edges of the left reflector plate and the sky-side reflector plate overlap with each other, and an overlapping edge of the left reflector plate and the sky-side reflector plate are perpendicular to an edge of the plane portion;
adjacent edges of the right reflector plate and the sky-side reflector plate overlap with each other, and an overlapping edge of the right reflector plate and the sky-side reflector plate are perpendicular to the edge of the plane portion.
