In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1, the back plate light emitting structure of the tv set includes:

a back plate 10 installed at the back of the television;

the reflecting film 20 is arranged on the back plate 10, the reflecting film 20 is cup-shaped, the inner wall of the reflecting film 20 is provided with a plurality of light leaking parts 30, and the included angle between the inner wall of the reflecting film 20 and the horizontal plane is smaller than 90 degrees;

the lamp bead 40, the lamp bead 40 is provided with a plurality of, the lamp bead 40 is installed on the bottom surface of reflection of light diaphragm 20.

In this embodiment, the light leakage part 30 includes a concave hole 31 formed on an inner wall of the reflective film 20, and when light is incident into the concave hole 31, the light passes through the reflective film 20 and is emitted into a gap between the back plate 10 and the reflective film 20 without being reflected onto the screen, and it should be mentioned that the light leakage part 30 includes at least one concave hole 31.

In the actual use process, after the light of the lamp bead 40 is emitted to the inner wall of the reflective membrane 20, the light passing through the light leakage part 30 is reduced, so that the light rays emitted to the light emitting center through reflection are reduced, the brightness of the central area is reduced and tends to be consistent with that of the edge, and the light emitting of the whole television screen is more uniform in visual effect. Referring to fig. 2, the arrows indicate the paths of the light rays, and the light rays are incident into the concave holes 31 and are not reflected, so that the light efficiency of the central area is reduced, and the uniformity of the light is improved.

In this embodiment, the distance between the bead 40 disposed on the edge of the bottom surface of the reflective film 20 and the edge of the bottom surface of the reflective film 20 is 1-3 cm. The lamp beads 40 are arranged at the position close to the edge of the bottom surface, so that the light effect of the central area is reduced, and the light effect of the edge position is improved.

In this embodiment, a plurality of the light leakage parts 30 on the same inner wall are arranged in a straight line, and the distance between the light leakage parts 30 and the lower edge of the inner wall is 1-3 cm. It is ensured that the light to be reflected to the central region is emitted outside in the light leakage portion 30.

In some embodiments, the bead 40 disposed on the edge of the bottom surface of the reflective film 20 corresponds to the position of the light leakage part 30. The light energy emitted by the lamp beads 40 is ensured to be accurately emitted into the light leakage part 30.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
