Space segment 2012 is more than the area of section of the first space segment 2011 in the area of section on the direction of side wall 111, therefore,
Flexible PCB 131 is located at the situation in second space section 2012, can be provided enough when adjusting the height of lamp source 132
Adjustment space, when preventing adjustment space deficiency, by reducing thickness at least one in the first stickers 14 and the second stickers 15
Degree, and cause the sticking strength of flexible PCB 131 insufficient, or in order to ensure the sticking strength of flexible PCB 131, lead to lamp
The height in source 132 and the height of light guide plate 121 be not corresponding, and the case where reduce the backlight effect of light guide plate 121.
Further, the backlight module 20 of the present embodiment further includes shading rubber belt 16, and shading rubber belt 16 is separate in roof 113
The side of accommodating space 201 is pasted on roof 113 and optical diaphragm group 12, when optical diaphragm group 12 shines, to prevent optics
12 light leakage of diaphragm group.
Specifically, shading rubber belt 16 is pasted on roof 113 and optical film in side of the roof 113 far from accommodating space 201
The upper anti-reflection film 122c of piece group 12.
Optionally, shading rubber belt 16 is pasted on the interconnecting piece 1222 of diffusion barrier 122a, specifically, 1222 self-diffusion of interconnecting piece
Main body 1221 extends to the direction far from light guide plate 121 namely 1222 self-diffusion main body 1221 of interconnecting piece is prolonged to shading rubber belt 16
It stretches, to be pasted on shading rubber belt 16.
Optionally, in other embodiments, shading rubber belt 16 also in side wall 111, paste by the side far from accommodating space 201
In side wall 111, to increase the bonding area of shading rubber belt 16 and back frame 21, to increase the stickup of shading rubber belt 16 and backlight 21
Intensity.
Backlight module provided in this embodiment, by the way that the flexible PCB of optical module and backlight may be contained within back frame
Bottom wall on, flexible PCB is carried by bottom wall, eliminates and is used to carry the glue frame of flexible PCB in the prior art, to
Space of the backlight module on the direction perpendicular to side wall shared by glue frame is eliminated, and then is reduced on the direction perpendicular to side wall
Width, realize the narrow side of backlight module, and further, flexible PCB be located to the second space section of accommodating space,
Area of section of the second space section on the direction towards side wall is more than the section of the first space segment for housing optical module
Area can provide enough adjustment spaces, when preventing adjustment space deficiency, by reducing by the when adjusting the height of lamp source
At least one thickness in one stickers and the second stickers, and cause the sticking strength of flexible PCB insufficient, or in order to protect
The sticking strength of flexible PCB is demonstrate,proved, the height for leading to lamp source and the height of light guide plate be not corresponding, and reduces the backlight of light guide plate
The case where effect.
