Embodiment
For making more clear the showing of the technical solution of the utility model, below in conjunction with specific embodiment, scheme of the present utility model is conducted further description.
As shown in Figures 3 and 4, glue frame 1 ' is four frameworks that side surrounds, at least one inner side edge of glue frame 1 ' has the groove of the lug of accommodating blooming piece, the upper surface place of glue frame 1 adjacent recess 11 ' is also provided with the adhesive tape tank 11 ' extending towards groove, the adhesive tape 2 ' arranging in adhesive tape tank 11 ' can be located blooming piece 3 ' in the direction perpendicular to glue frame 1 ' place plane, covers the corner point B of the lug 31 ' of blooming piece simultaneously.
Wherein, adhesive tape tank 11 ' is provided with the first outlet 111 ' towards the inner side edge extension of glue frame 1 ', and the adhesive tape of deriving from outlet can cover the corner point B of the lug 31 ' of blooming piece.Adhesive tape tank 11 ' arranges the outlet of adhesive tape towards glue frame inner side edge direction, can make adhesive tape extend the corner point of the lug of blooming piece is covered completely to blooming piece side when adhesive tape is installed.In addition, adhesive tape tank 11 ' is also provided with the second outlet 112 ' extending towards groove side, the adhesive tape of drawing from the second outlet 112 ' is crossed over groove, so the lug 31 ' of the blooming piece of groove can be located in the direction perpendicular to glue frame 1 ' place plane.Under the first outlet 111 ' and described the second outlet 112 ' effect, described adhesive tape tank is configured as L shaped.The height of described adhesive tape tank 11 ' is more than or equal to the thickness of adhesive tape 2 ', and the height of groove is more than or equal to the thickness of blooming piece 3 ', to reduce the thickness of backlight module.
In the present embodiment, pass through to change the set-up mode of adhesive tape tank, the adhesive tape that makes to draw from adhesive tape tank can be crossed over the lug of blooming piece, and can cover the corner point of the lug of blooming piece completely, can effectively improve the some light leak problem that lug corner point place produces.The magnitude setting of adhesive tape tank can be selected arbitrarily according to actual conditions, can for one can be also two adhesive tape tanks that are oppositely arranged.When an adhesive tape tank is set, need the ear bonding of adhesive tape and blooming piece fixing, with positioning optical diaphragm.When two relative adhesive tape tanks are set, do not need the ear bonding of adhesive tape and blooming piece.In addition, the structure of adhesive tape tank is not limited to form shown in Fig. 3 and 4, can expect can being also rectangle, as illustrated in Figures 5 and 6; Or can also be further two independences, disjunct rectangle adhesive tape tank, the adhesive tape of deriving in one of them adhesive tape tank be for the lug of positioning optical diaphragm, and the adhesive tape of deriving in another adhesive tape tank is for covering the corner point of the lug of blooming piece.In a word, described blooming piece can be located in the direction perpendicular to described glue frame body place plane, the distortion of arbitrary adhesive tape tank of corner point that simultaneously covers the lug of described blooming piece all should be thought and falls into protection domain of the present utility model.
As shown in FIG. 7 and 8, backlight module of the present utility model, comprises glue frame 1 ', the adhesive tape 2 ' of above-described embodiment and is installed in the blooming piece 3 ' in glue frame:
The outer rim of blooming piece 3 ' has lug 31 ';
Glue frame 1 ' comprises glue frame body, and described glue frame body is four frameworks that side surrounds, and at least one inner side edge of described glue frame body has the groove of accommodating lug;
The upper surface place of described glue frame body adjacent recess is also provided with the adhesive tape tank 11 ' extending towards described groove, adhesive tape 2 ' is arranged in adhesive tape tank 11 ', and described blooming piece 3 ' can be located in the direction perpendicular to described glue frame body place plane, cover the corner point B of the lug 31 ' of described blooming piece simultaneously.Due to the structure of glue frame technique effect in embodiment before, be described in detail at this and no longer repeat.
Blooming piece is because high temperature can expand when work, if blooming piece is fixed, adhesive tape clings and can limit its expansion, can affect in this case the image quality of the whole picture of display screen.In order to prevent this from occurring, preferred, adhesive tape is divided into light shielding part and connecting portion two parts, only at connecting portion place, adhesive glue is set, and adhesive glue is not set at light shielding part place, described light shielding part is connected between described two connecting portions and with two connecting portions; The shape of the shape of described connecting portion and described adhesive tape tank matches, and is bonded and fixed in described adhesive tape tank; Described light shielding part is positioned at the lug top of described blooming piece, and described blooming piece is located in the direction perpendicular to described glue frame body place plane, covers the corner point connecting portion of the lug of described blooming piece simultaneously.In the present embodiment, at light shielding part, adhesive glue is not set, the lug for can positioning optical diaphragm, need to be oppositely arranged in the both sides of groove two adhesive tape tanks.According to the shape of the different adhesive tapes of the shape of adhesive tape tank, can be " protruding " shape or rectangle.When adhesive tape tank is L shaped, the adhesive tape of installing is shaped as " protruding " shape, as shown in Figure 7; When adhesive tape tank is rectangle, adhesive tape is shaped as rectangle, as shown in Figure 8.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
