Furthermore, the both ends of fixed strip all are equipped with the buckle, the both sides wall of outlet corresponds the buckle is equipped with a draw-in groove respectively, the buckle can the card be gone into correspondingly realize in the draw-in groove the fixed strip is in the dismantlement of outlet department is fixed.

Furthermore, an adhesive layer is arranged between the fixing strip and the connecting part.

Further, the bonding layer is double-sided adhesive tape.

Further, the fixing strip is a plastic strip.

Further, the fixing strip is black or gray.

Further, backlight unit still includes a plurality of membrane materials, the membrane material is located the fixed strip is close to this side of backplate, the fixed strip can be used as the barricade and the shading of membrane material are glued and are pasted the position.

Further, the Mini L ED lamp panel is of a polygonal structure.

The utility model also provides a display, include as above backlight unit.

By adopting the scheme, the utility model discloses an independent fixed strip is designed, make the Mini L ED lamp plate that has the broad outlet be convenient for assemble, the fixed strip can also provide the barricade for the membrane material simultaneously, the location of the membrane material of being convenient for avoids the outlet light leak, and the light efficiency of being convenient for is handled, and independent detachable fixed strip shaping is more nimble with the installation.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 4 to 7, the present invention provides a backlight module, including a back plate 1, a Mini L ED lamp plate 2 disposed on the back plate 1, a connecting portion 3 disposed between the Mini L ED lamp plate 2 and a gold finger, a detachable fixing strip 5 disposed at the outlet 4 of the connecting portion 3 corresponding to the back plate 1, and a detachable fixing strip 5 disposed at the outlet 4, wherein the fixing strip 5 can fix the connecting portion 3. the present invention, by designing the independent detachable fixing strip 5, effectively solves the problems of unable normal assembly, unable positioning of a film material, severe light leakage at one side, and the like due to the wide width of the existing Mini L ED lamp plate outlet, after the backlight module is assembled, the fixing strip 5 is mounted on the lamp plate, and can fix the lamp plate, and at the same time provide a retaining wall for the film material, thereby improving the stability of the film material, and the fixing strip 5 can also provide an adhesive position for a shading adhesive, thereby avoiding the outlet 4. the independent fixing strip 5 does not affect the normal molding of the back plate 1, and the molding and the mounting is more convenient, particularly, and the fixing strip 5 is a plastic strip for the light leakage design of a special-shaped plastic strip.

Specifically, in this embodiment, both ends of the fixing strip 5 are provided with the buckles 6, the two side walls of the outlet 4 correspond to the buckles 6 are provided with the clamping grooves 7 respectively, the buckles 6 can be clamped into the corresponding clamping grooves 7 to realize the fixing strip 5 is detachably fixed at the outlet 4. In the case of sufficient space, the connection of the fixing strip 5 to the back plate 1 can be made more stable by the above design.

Specifically, in this embodiment, an adhesive layer (not shown in the figure) is disposed between the fixing strip 5 and the connecting portion 3, and after the backlight module is assembled, the fixing strip 5 is adhered to the connecting portion 3 by a double-sided adhesive.

Specifically, in this embodiment, the fixing strip 5 is a black or gray plastic strip, which can solve the problem that the wider side of the outlet 4 has a risk of light leakage, and does not affect the overall brightness of the backlight module, and of course, the fixing strip 5 may also be other materials having the above-mentioned light-shielding function.

Specifically, in this embodiment, the backlight module further includes a plurality of film materials, the film materials are located on the side where the fixing strip 5 is close to the back plate 1, and the fixing strip 5 can be used as a retaining wall of the film materials to play a role in positioning.

No matter be abnormal-shaped structures such as normal tetragonal or octagon, the outlet is all very wide, almost with one side of backplate 1 is the same width, specifically in this embodiment, Mini L ED lamp plate 2 is the octagon structure, connecting portion 3 is the octagon one side of Mini L ED lamp plate 2, correspondingly, outlet 4 almost with one side of backplate 1 is the same width, increases fixed strip 5 can be fixed in Mini L ED lamp plate 2, can also prevent this one side light leak of outlet 4 promotes optical effect.

The utility model also provides a display, include as above backlight unit.

To sum up, the utility model discloses an independent fixed strip of design makes the Mini L ED lamp plate that has the broad outlet be convenient for assemble, and the fixed strip can also provide the barricade for the membrane material simultaneously, and the location of the membrane material of being convenient for avoids the outlet light leak, and the light efficiency of being convenient for is handled, and independent detachable fixed strip shaping is more nimble with the installation.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
