Background
The lateral backlight module is characterized in that the light source is arranged on the side edge of the light guide plate, and the lateral backlight module can be thinned compared with the direct backlight module, but the lateral backlight module can increase the size of a frame on the light incident side. At present, with the gradual development of display technologies, there is a higher requirement for the appearance of display devices, and a narrow-bezel display apparatus can increase the aesthetic feeling of display, so that various display devices gradually require a narrow bezel around a display panel.

As can be seen, in fig. 1, when the visible area is the area a-a, the frame width of the display device is L1, and at this time, the frame width of the display device is wider, which cannot meet the requirement of the narrow frame of the display device; when the visible area is B-B, because there is a gap X between the flexible circuit board 02 and the reflective sheet 05, light can enter the reflective sheet 05 and be reflected, at this time, a bright line can be formed in the X area and finally displayed on the display panel, and due to the existence of the fixing tape in the Y area, the light entering the Y area can also be reflected to form a different color on the display panel, and the existence of the bright line and the different color can affect the display effect of the display panel. It can be seen that the display device provided in the prior art cannot meet the requirements of both the narrow bezel and the quality of the display device.

the light guide plate 40 is arranged on one side, away from the substrate 10, of the second reflection sublayer 32;
and the light source 50 is arranged on one surface of the flexible circuit board 20 departing from the substrate 10 and arranged around the light guide plate 40, and the light emitting direction of the light source 50 faces the light guide plate 40.
The light source 50 is disposed around the light guide plate 40, and the light source 50 may be disposed around one side of the light guide plate 40, or may be disposed around multiple sides or four sides, specifically, disposed as needed.
In the embodiment of the present invention, referring to fig. 2, since the second reflective sublayer 32 covers the first reflective sublayer 31 and a part of the area of the flexible circuit board 20 close to the second reflective sublayer 32 at the same time, the second reflective sublayer 32 covers the gap Z between the first reflective sublayer 31 and the flexible circuit board 20, so that the light emitted by the light source 50 enters the light guide plate 40 and does not enter the gap Z, and the gap Z does not form a bright band, so that the display effect of the display device is not affected.
In the embodiment of the invention, because the second reflective sublayer 32 is arranged between the flexible circuit board 20 and the light guide plate 40, no fixing tape is added on one surface of the light guide plate 40 facing the second reflective sublayer 32, so that no heterochrosis is generated on the display device, the display area C-C of the display device can be enlarged, the frame of the display device is narrowed, and the display quality of the display device is improved.
In an embodiment of the present invention, referring to fig. 3, the first reflective sublayer 31 includes: a body layer 311 and a highly reflective sublayer 312; the high reflection sublayer 312 is disposed on the substrate 10; the main body layer 311 is disposed on a side of the high reflection layer 312 facing away from the substrate 10.
The first reflective sub-layer may be divided into two layers, the main layer 311 is made of PET (polyethylene terephthalate) polymer material, metal film, TiO2 (titanium dioxide), and the like, and the high reflective sub-layer may be made of polymer protective material or polymer material with high reflective performance to improve the reflective performance of the reflective layer 30.

In the embodiment of the present invention, the first adhesive layer is disposed between the second reflective sub-layer 32 and the flexible circuit board 20, and is used for fixing the second reflective sub-layer 32 and the flexible circuit board 20;
since the first adhesive layer is not disposed between the light guide plate 40 and the second reflective sub-layer 32, the problem of color difference on the light guide plate side does not occur.

In the embodiment of the invention, the light emitted from the light source 50 enters the light guide plate 40, enters the second reflective sub-layer 32 through the lower surface of the light guide plate 40, and is reflected back to the light guide plate 40 through the second reflective sub-layer 32. The phenomenon that light rays incident to the lower surface of the light guide plate 40 are different in color under the reflection of the fixing adhesive tape or the phenomenon that the side surface of the reflection layer close to the flexible circuit board reflects the light rays to generate bright lines can be avoided.
