Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is the utility model part of the embodiment, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model embodiment provides a kind of back light source structure, as shown in Fig. 2 the back light source structure includes：Glue frame 4 with
And the light guide plate 2 in glue frame is arranged on, the medial surface of glue frame 4 is provided with stiffener 5 at the exiting surface away from light guide plate 2, guide-lighting
The side of plate 2 is engaged with the medial surface of glue frame 4.
In the back light source structure that the present embodiment provides, the medial surface of glue frame 4 is provided with the exiting surface away from light guide plate 2
Stiffener 5, and the side of light guide plate 2 is engaged with the medial surface of glue frame 4, this is allowed in order to realize the backlight of narrow frame
Source, when the thickness of glue frame 4 is reduced, stiffener 5 can be in the case where not influenceing the narrow frame of backlight, widened section glue frame 4
Width, play a part of reinforcement, so as to enhance the intensity of glue frame 4, avoid and glue frame 4 occur and deform, the problem of fracture,
And then improve the yields of the backlight of production.While backlight ultra-narrow frame is realized, can reduce glue frame volume production difficulty,
Improve the situation of glue frame deformation and fracture.
Exemplarily, as shown in Fig. 2 above-mentioned stiffener 5 can be wedge-shaped stiffener, when light guide plate is edge-type light guide plate
When, above-mentioned stiffener can be to have semi-enclosed structure jaggy, and breach possessed by the stiffener is made with edge-type light guide plate
It is for the side of incidence surface relative, enter light so as to avoid stiffener from influenceing backlight.
Stiffener 5 and glue frame 4 can be integral or independent be formed separately.
Exemplarily, as shown in Fig. 2 the wall thickness of glue frame 4 is d1, the Breadth Maximum of stiffener 5 is d2, reaching glue frame 4
In the case of fundamental strength requirement, in order to meet the needs of narrow frame backlight, preferably 0.2mm ＜ in the utility model embodiment
d1≤ 0.4mm, and as the wall thickness d of glue frame 41With the Breadth Maximum d of stiffener 52Meet 0.5mm≤d1+d2During≤0.65mm, no
The narrow frame of back light source structure can be only realized, can also effectively be carried by stiffener 5 in the case where not influenceing backlight and lighting
The intensity of high glue frame 4, avoid the occurrence of glue frame 4 and deform, the problem of fracture, and then improve the yields of the backlight of production.It is above-mentioned
The width of stiffener 5 is identical with the wall thickness direction of glue frame 4.
Further, as shown in Fig. 2 inventor has found, as the maximum height d of stiffener 53It is higher, the maximum of stiffener 5
Width d2When bigger, stiffener 5 is bigger to the support force of glue frame 4, then the intensity of glue frame 4 is also bigger, but stiffener 5 is too high
Or when wide, the reflection light of back light source structure will increase, and cause the side of backlight that bright line occurs, will influence backlight
The luminescent properties in source, therefore, the maximum height of preferred stiffener 5 in the utility modelIn addition, work as stiffener
When 5 width reduces with the increase of the height of stiffener 5, can also the situation of support of the stiffener 5 to glue frame 4 be not being influenceed
Under, reduce luminous influence of the stiffener 5 to back light source structure.
Exemplarily, as shown in Fig. 2 back light source structure also includes the blooming piece being arranged on the exiting surface of light guide plate 2
3, blooming piece 3 is bonded together by shading rubber belt 6 and glue frame 4.By using shading rubber belt 6 by blooming piece 3 and glue frame 4
It is bonded together, on the one hand can improves the stability of back light source structure, on the other hand, fixed blooming piece 3 can be played
Effect, prevents blooming piece 3 from moving, avoids impacting the light extraction of backlight.
Alternatively, as shown in Fig. 2 the blooming piece that shading rubber belt 6 may include to be arranged on the edge of blooming piece 3 is fixed
Portion 61 and the glue frame fixed part 62 being bonded on the lateral wall of glue frame 4.Blooming piece fixed part 61 and glue frame fixed part 62 can be with
It is integral or is formed separately.Such as can be that blooming piece fixed part 61 extends to bending on the outside of glue frame
Form.Shading rubber belt reflexed attaches the area of attachment that can increase shading rubber belt and glue frame, improves backlight reliability.
Inventor has found, as shown in Fig. 2 because shading rubber belt 6 is double-sides belt glue, therefore, if the glue frame of shading rubber belt 6
Length d of the fixed part 62 in the short transverse of glue frame 44When oversize, foreign matter is easily glued, and then influences backlight and display dress
The assembling put, and if length d of the glue frame fixed part 62 of shading rubber belt 6 in the short transverse of glue frame4It is too short, then can not be effective
Blooming piece 3 and glue frame 4 are bonded, therefore, in the utility model embodiment, preferably glue frame fixed part is in the short transverse of glue frame
Length d4For 0.2mm~0.4mm.
Exemplarily, above-mentioned blooming piece may include diffusion sheet, the rib being cascading on the exiting surface of light guide plate
Eyeglass and bright enhancement film.
In addition, the utility model embodiment also provides a kind of display device, including above-mentioned back light source structure.With prior art
Compare, the beneficial effect phase of the beneficial effect and the structure of above-mentioned backlight of the display device that the utility model embodiment provides
Together, therefore no longer repeated herein.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
