Technical Field
[0001] The utility model relates to the technical field of bright line prevention structures, in particular to a backlight source bright line prevention structure. Background Art
[0002] The backlight is a light source located behind the liquid crystal display (LCD). Its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). The LCD itself does not emit light, it displays graphics or the result of its light modulation.
[0003] The existing anti-brightness line structure usually sticks a black PET film on the edge of the display screen, but the PET film is easy to fall off during use, which makes the overall use effect not good. For this reason, we propose a backlight source anti-brightness line structure. Utility Model Content
[0004] In view of the above problems, the utility model provides a backlight source anti-brightness line structure, which can solve the problems existing in the above background technology.

[0006] A backlight source anti-brightness line structure comprises a display panel, wherein a mounting groove is provided at the bottom end of the display panel, a diffusion film and a light guide plate are provided inside the mounting groove, the diffusion film is located above the light guide plate, and a black PET film is provided on the outer edge of the diffusion film.
[0007] In a further technical solution, the top edge of the display panel is provided with black ink.
[0008] In a further technical solution, the bottom end of the black PET film and the top edge of the light guide plate are bonded to each other.
[0009] In a further technical solution, the cross-sectional shape of the black PET film is in a vertical state and is located between the display panel and the diffusion film.
[0010] In a further technical solution, the top of the diffusion film and the inner bottom of the display panel are bonded to each other.
[0011] In a further technical solution, the overall thickness of the diffusion film and the light guide plate is equal to the depth of the mounting groove.
[0012] In a further technical solution, the inner edge of the black ink is at the same position as the top edge of the black PET film.
[0013] The beneficial effects of the utility model are:
[0014] 1. The display panel, diffusion film, light guide plate and black PET film are provided, and the black PET film is in an upright state and located outside the diffusion film and between the display panel and the light guide plate, which can effectively avoid the overall edge bright line and improve the use stability of the black PET film to avoid loosening;
[0015] 2. The black ink can be used as a whole to further avoid bright lines on the edges, thereby improving the overall use effect. The overall structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0022] Example:
[0023] like Figure 1-Figure 3 As shown, a backlight source anti-bright line structure includes a display panel 1, a mounting groove 2 is opened at the bottom end of the display panel 1, a diffusion film 3 and a light guide plate 4 are arranged on the inner side of the mounting groove 2, the diffusion film 3 is located above the light guide plate 4, and a black PET film 5 is arranged on the outer edge of the diffusion film 3.
[0024] The working principle of the above technical solution is as follows:
[0025] When in use, the black PET film 5 can be outside the edge of the diffusion film 3, and the black PET film 5 can be restricted between the display panel 1 and the light guide plate 4, so that the black PET film 5 can avoid bright lines on the edges while also being able to be used stably for a long time, thereby improving the overall performance.
[0026] In another embodiment, if Figure 1 As shown, the top edge of the display panel 1 is provided with black ink 6.
[0027] The black ink 6 can further improve the overall anti-bright line effect.
[0028] In another embodiment, if Figure 1 and Figure 2 As shown, the bottom end of the black PET film 5 and the top edge of the light guide plate 4 are in contact with each other.
[0029] This facilitates the black PET film 5 to be stably located at the top edge of the light guide plate 4 for use, thereby ensuring that it is stably located inside the display panel 1 for use.
[0030] In another embodiment, if Figure 2 As shown, the cross-sectional shape of the black PET film 5 is in a vertical state and is located between the display panel 1 and the diffusion film 3 .
[0031] The black PET film 5 can block the outer edge of the diffusion film 3 and can also be stably placed between the display panel 1 and the light guide plate 4 for use to avoid loosening.
[0032] In another embodiment, if Figure 1 and Figure 2 As shown, the top of the diffusion film 3 and the inner bottom of the display panel 1 are attached to each other.
[0033] This facilitates the diffusion film 3 to be stably located inside the display panel 1 for use.
[0034] In another embodiment, if Figure 1 and Figure 2 As shown, the overall thickness of the diffusion film 3 and the light guide plate 4 is equal to the depth of the mounting groove 2 .
[0035] This facilitates the diffusion film 3 and the light guide plate 4 to be stably located inside the mounting groove 2 and connected to the display panel 1 for use.
[0036] In another embodiment, if Figure 1 and Figure 2 As shown, the inner edge of the black ink 6 is at the same position as the top edge of the black PET film 5 .
[0037] This facilitates the cooperation between the black ink 6 and the black PET film 5 , further avoiding the occurrence of bright lines at the edges, and improving the overall use effect.
[0038] Working principle of the utility model: during use, firstly, the diffusion film 3 is placed on the inner side of the mounting groove 2 and connected with the display board 1, then the black PET film 5 is clamped between the display board 1 and the diffusion film 3, and finally the light guide plate 4 is placed on the inner side of the mounting groove 2, in contact with the diffusion film 3 and the black PET film 5. The black PET film 5 can mainly prevent bright lines from occurring on the edge of the diffusion film 3. When combined with the black ink 6, the black ink 6 can prevent bright lines from occurring on the edge of the display board 1, and can also further enhance the use effect of the black PET film 5, thereby improving the overall anti-bright line effect and ensuring stable use.
[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
