Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the backlight module of the utility model one embodiment；
Fig. 2 is the sectional view in Fig. 1 along the direction A-A.
Specific embodiment
It is carried out with reference to embodiments with technical effect of the attached drawing to the design of the utility model, specific structure and generation clear
Chu is fully described by, to fully understand the purpose of this utility model, scheme and effect.It should be noted that in the feelings not conflicted
The features in the embodiments and the embodiments of the present application can be combined with each other under condition.Furthermore used in the utility model it is upper,
Under, the descriptions such as left and right be only in opposite figure for each component part mutual alignment relation of the utility model.
Figures 1 and 2 show that a kind of backlight module 100, offers on backlight module 100 for placing camera or listening
The through-hole 110 of cylinder, backlight module includes function body and is used to support, the fixed frame 120 of positioning function main body, because of through-hole
Camera is placed in 110, if light leakage in through-hole, light can be made to be irradiated to camera, and then influence the camera function of camera.
As shown in Fig. 2, fixed frame 120 includes the first support portion 121 contacted with function body and the side for being close to through-hole 110
Edge setting and protrude into the second support portion 122 in through-hole 110, the surface of function body is pasted with the first light shield layer 140, first
Light shield layer 140 is arranged around through-hole 110, and the second support portion 122 is equipped with the second light shield layer 150 backwards to the side of function body, and the
Two light shield layers 150 partly overlap with the first light shield layer 140.
Because there are gaps between the second support portion 122 and the end of function body, set on the surface of function body
The first light shield layer 140 is set to cover gap, prevents light from leaking out from gap.Function body is arranged in first light shield layer 140
Surface, and the light emission side of function body is additionally provided with other optical elements, therefore the first light shield layer 140 is two-sided to all have viscosity
Shading glue, therefore the edge of the inside of the first light shield layer is bonded with the end face of the second support portion, but is no more than the second support end surface
The visual side of outermost.
Function body in the utility model includes the reflectance coating 131, light guide plate 132, diffusion barrier 133 being cascading
