Abstract

The embodiments of the present disclosure relate to the technical field of manufacturing display device, and disclose a backlight golden finger structure and a display device. The backlight golden finger structure includes: a plurality of golden finger bodies, one end of each golden finger body being configured to be connected with a backlight flexible circuit board, the other end of each golden finger body being overhung and configured to be connected with a display panel flexible circuit board at a first surface of the backlight golden finger structure; and a first covering film disposed on the first surface of each golden finger body, an edge of the first covering film adjacent to the overhung end of the golden finger body being in a curved shape.

First claim

What is claimed is:

1. A backlight golden finger structure, comprising:
a plurality of golden finger bodies, a first end of each of the plurality of golden finger bodies being configured to be connected with a backlight flexible circuit board, and a second end of each of the plurality of golden finger bodies being overhung and configured to be connected with a display panel flexible circuit board at a first surface of each of the plurality of golden finger bodies; and
a first covering film disposed on the first surface of each of the plurality of golden finger bodies, an edge of the first covering film adjacent to the overhung second end of the golden finger body being in a curved shape,
wherein a second covering film is provided on a second surface of each golden finger body facing away from the first surface, and an edge of the second covering film adjacent to the overhung end of the golden finger body is in a curved shape,
wherein a pattern of an orthographic projection of the edge of the first covering film adjacent to the overhung end of the golden finger body onto the display panel flexible circuit board does not intersect a pattern of an orthographic projection of the edge of the second covering film adjacent to the overhung end of the golden finger body onto the display panel flexible circuit board, and
wherein the edge of the first covering film adjacent to the overhung end of the golden finger body is closer to the overhung end of the golden finger body than the edge of the second covering film adjacent to the overhung end of the golden finger body.

2. The backlight golden finger structure according to claim 1 , wherein,
a shape of the edge of the first covering film adjacent to the overhung second end of the golden finger body is the same as a shape of the edge of the second covering film adjacent to the overhung second end of the golden finger body.

3. The backlight golden finger structure according to claim 2 , wherein,
the golden finger body further comprises a through hole penetrating through the first covering film, the golden finger body and the second covering film.

4. The backlight golden finger structure according to claim 1 , wherein the curved shape is a wavy line.

5. The backlight golden finger structure according to claim 4 , wherein,
the golden finger body further comprises a through hole penetrating through the first covering film, the golden finger body and the second covering film.

6. The backlight golden finger structure according to claim 1 , wherein,
the golden finger body further comprises a through hole penetrating through the first covering film, the golden finger body and the second covering film.

7. The backlight golden finger structure according to claim 6 , wherein,
a position of the through hole provided in a first one of any two adjacent golden finger bodies is different from a position of the through hole provided in a second one of the any two adjacent golden finger bodies.

8. A display device, comprising a backlight flexible circuit board and a display panel flexible circuit board, wherein, the display device further comprises the backlight golden finger structure of claim 1 .
