Embodiment

[0027] Such as figure 2 as shown, figure 2 It is a structural schematic diagram of the backlight module in the embodiment. In this embodiment, the display device of the present invention includes a backlight module 10 , wherein the backlight module 10 includes a frame 100 , a light source 200 , a light guide plate 300 , an adhesive layer 400 , a circuit board 500 and a lamp glue 600 .

[0028] The outer frame 100 is a metal outer frame. Specifically, the outer frame 100 includes a bottom plate 101 and a side plate 102, wherein the side plate 102 surrounds the edge of the bottom plate 101 and is perpendicular to the bottom plate 101. The bottom plate 101 and the side plate 102 form a cavity. , the cavity is used to accommodate and fix other components of the backlight module 10, and the metal material can shield light and avoid light leakage.

[0029] The circuit board 500 is arranged in the cavity and is located on the upper surface of the base plate 101. The circuit board...

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises: a light source; a light guide plate which comprises a light incident side, wherein the light incident side faces the light source; and an adhesive layer which is arranged between the light source and the light incident side of the light guide plate. The backlight module and the display device have thebeneficial effects that the adhesive layer below the light guide plate is removed, so that the overall thickness of the backlight module is reduced, and the ultrathin display device is favorably realized. According to the invention, the light guide plate incident side and the light source are connected through the transparent adhesive layer, the transparent adhesive layer is arranged in the gap between the point light sources and on the light guide plate incident side corresponding to the gap, the light guide plate is fixed from the side face, light paths of light entering the light guide plate in the light source are consistent, and the light emitting stability of the backlight module is improved.

Description

technical field [0001] The present application relates to the field of backlight, in particular to a backlight module and a display device. Background technique [0002] figure 1 In order to be a schematic diagram of the structure of the backlight module in the existing design, the function of the front lamp glue (reverse group) of the usual backlight LED is to fix the light source (LED) 200 and the LGP light guide plate 300 to ensure the processing of brightness and light efficiency . The front lamp glue is attached to the bottom of the LGP light guide plate 300, which increases the thickness of the backlight module to a certain extent. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a backlight module and a display device to solve the technical problem in the prior art that the overall thickness of the backlight module is increased due to the arrangement of lamp glue under the light guide plate. [0004...
