Extend on 1012 ' second direction b, projection 1031 is arranged at the second film layer 103 a extensions and close first adhesive tape in the first direction
On the edge in area 1012 '.Wherein, the opening 104 being arranged in the first film layer 102 can be as shown in Figure 6 in second direction b
On the first film layer of not insertion 102, can also the first film layer of insertion 102.
The backlight module that the embodiment is provided, is set in the second film layer 103 on the edge of the first taped region 1012 '
Have projection 1031, projection 1031 as the second film layer 103 a part, it is not with shading rubber belt adhesion and convex in second direction b
Go out the film layer structure of backlight module, be easy to tear up the second film layer 103 from backlight module.
In the embodiment, the position of the projection 1031 set for the second film layer 103 in a top edges in the first direction is not
Limit, projection 1031 is arranged on any position of the second film layer 103 a top edges in the first direction, can play auxiliary and tear
Except the effect of the second film layer 103, it is preferred that on second direction b, the center line of projection 1031 and opening 104 is located at always
On line, since backlight module be located at same remove the second film layer 103 raised 1031 position when with the center line of projection 1031
There is maximum rising to tear active force, the position is used as the breach for removing the second film layer 103 at opening 104 on straight line, it is easy to
Second film layer 103 is removed.
In some optional embodiments, Fig. 7 is another optional reality of backlight module provided in an embodiment of the present invention
Apply the schematic top plan view of mode.As shown in fig. 7, in a first direction on a, raised 1031 orthographic projection and opening in shading glue belt
104 are located at sustained height H in the orthographic projection of shading glue belt, namely on b in a second direction, 104 pairs of projection 1031 and opening
It should set, the backlight module that the embodiment is provided, when the second film layer is torn up from raised 1031 position, in the position of opening 104
Active force maximum is torn in rising for b in a second direction by place, it is easy to remove the second film layer.
It should be noted that the first film layer only contacts adhesion with the second film layer, from the first film layer and the second film layer contact jaw
Start to remove the second film layer, projection 1031 is in the orthographic projection of shading glue belt and opening 104 in the orthographic projection position of shading glue belt
In different height, the effect that auxiliary tears up the second film layer can be realized, within the scope of protection of the invention.
Further, in some optional embodiments, with reference to Fig. 8 and Fig. 9, Fig. 8 is provided in an embodiment of the present invention
First film layer of backlight module sets the structural representation of opening, and Fig. 9 is the first of backlight module provided in an embodiment of the present invention
Film layer sets the structural representation of another optional embodiment of opening, as shown in Figure 8 and Figure 9, and opening 104 is in shading rubber belt
The orthographic projection of layer has first edge 1041 and second edge 1042, wherein, first edge 1041 is formed with second edge 1042
Angle theta, bearing of trend, the bearing of trend of second edge 1042 and the first direction a of first edge 1041 are differed.
In the embodiment, set opening that there is an angle theta, backlight module acts the position torn when removing the second film layer
Put be angle theta summit, resistance will be torn off and concentrated on a point, greatly reduce remove the second film layer rise tear resistance, energy
Enough easily the second film layer is torn up using less tearing force, then extended toward both sides from tearing up position, it is to avoid tear off the
Shading rubber belt is elongated or deformed during two film layers, the risk of backlight module light leak is reduced.In the embodiment, it is open such as to scheme
During triangle shown in 8, hatch frame is simple, is easy to cut when cutting the first film layer.But the present invention does not limit opening
Be shaped as triangle or the polygon shown in Fig. 9.Opening for setting, when the second film layer rises and torn, to tear off resistance
Situation about can concentrate on a point, within the scope of protection of the invention.
