[ first embodiment ]
Fig. 1 is a schematic structural diagram of an auxiliary device 10 according to a first embodiment of the present invention. Referring to fig. 1, in an embodiment of the present invention, an auxiliary device 10 for assembling a backlight module includes:
a cover reflecting sheet 11, the cover reflecting sheet 11 having an upper surface and a lower surface;
a release film 12 detachably attached to the lower surface of the lampshade reflection sheet 11; the release film 12 is a film having a film surface energy discrimination, and is not sticky or slightly sticky after being exposed to a specific material under a limited condition.
The adhesive tape 13, the adhesive tape 13 is set up on the upper surface of the reflecting sheet 11 of lamp shade;
wherein, have first end and second end from type membrane 12, keep away from the one end of lamp shade reflector plate 11 from type membrane 12 and be the second end, extend to the lamp shade reflector plate 11 outside from second end in the type membrane 12. When the lampshade reflecting sheet 11 is installed on the back plate 20, the release film 12 can be conveniently grabbed by hand, the lampshade reflecting sheet 11 adhered with the adhesive tape 13 is installed on the backlight module through the release film 12, in practical application, after the lampshade reflecting sheet 11 is assembled, the release film 12 needs to be stripped, the release film 12 extending from the second end of the release film 12 to the outer side of the lampshade reflecting sheet 11 can serve as a handle for auxiliary stripping, the release film 12 can be easily stripped, and the operation is convenient and fast.
Specifically, the length of the adhesive tape 13 is less than or equal to the length of the cover reflecting sheet 11. For convenience of description, it is defined that the longitudinal direction of the tape 13 coincides with the longitudinal direction of the cover reflecting sheet 11, and the width direction of the tape 13 coincides with the width direction of the cover reflecting sheet 11. The length of sticky tape 13 is less than the length of lamp shade reflector plate 11, and the width of sticky tape is less than or equal to the width of lamp shade reflector plate, can reduce too much sticky tape 13 and cause the waste of consumptive material easily, and sticky tape 13 is stained with other impurity easily simultaneously, influences the installation of other parts of backlight module.
Specifically, the first end of the release film 12 is disposed on the lower surface of the lampshade reflection sheet 11 and is flush with a side edge of the lampshade reflection sheet 11 near the first end. In the actual assembly process, the first end of the release film 12 is flush with the edge of one side of the lampshade reflection sheet 11 close to the first end, and when the lampshade reflection sheet 11 with the adhesive tape 13 is mounted in an auxiliary manner on the release film 12, the lampshade reflection sheet 11 is easier to align and attach.
Specifically, sticky tape 13 is the double faced adhesive tape, and the double faced adhesive tape both have the stickness from top to bottom, makes things convenient for lamp shade reflector plate 11 to install on the backlight module through sticky tape 13.
Specifically, the release film 12 is made of PET, and the PET material is Polyethylene Terephthalate (PET), so that the release film 12 has excellent product performance, stable peeling force and excellent flatness.
Fig. 2 is a cross-sectional view of a backlight module according to a first embodiment of the present invention; referring to fig. 2, the present invention further provides a backlight module including the auxiliary device 10.
Specifically, the method further comprises the following steps:
the back plate 20, the back plate 20 includes the mounting part 21, bears the weight of the department 22 and is used for connecting the mounting part 21 and connecting portion 23 bearing the weight of the department 22; the mounting part 21, the connecting part 23 and the bearing part 22 jointly enclose a semi-closed space; as a specific embodiment, the cross-sectional shape of the semi-closed space is substantially U-shaped.
The auxiliary device 10 is disposed in the semi-closed space, and the tape 13 attaches the lampshade reflecting sheet 11 to the inner side of the mounting part 21.
Specifically, the carrier 22 includes a reflector 30, a light guide plate 40, and an optical film group 50 stacked in sequence from bottom to top; the light guide plate 40 is further provided with a light emitting source 60 at a side thereof adjacent to the semi-enclosed space. When the light emitted from the light source 60 enters from the side of the light guide plate 40, the refractive index of the light guide plate 40 is greater than that of the air, so total reflection occurs to leave the light in the light guide plate 40, and the light is emitted to the light emitting surface through the scattering patterns or stripes in the light guide plate 40 in a scattered manner, and the sufficient scattering patterns or stripes can make the light leave from the light emitting surface uniformly, thereby achieving the effect of uniform surface light source. The reflective sheet 30 is disposed under the supporting portion 22, so that the intensity of incident light is increased. Meanwhile, the lampshade reflecting sheet 11 arranged on the inner side of the mounting part 21 of the back plate 20 can cover the light emitted above the light emitting source 60, so that light leakage can be effectively prevented, and light rays on the light emitting surface are further more uniform.
Specifically, the back plate 20 is an iron shell, so that the vehicle-mounted backlight module is more durable.
[ second embodiment ]
Fig. 3 is a cross-sectional view of a backlight module according to a second embodiment of the present invention. Referring to fig. 3, the auxiliary device 10 assembled with the backlight module according to the second embodiment of the present invention has substantially the same structure as the auxiliary device 10 assembled with the backlight module according to the first embodiment, except that: the cover reflecting sheet 11 extends outward with respect to a first end of the release film 12. By adopting the mode, the lamp shade reflecting sheet 11 can be extended into the semi-closed space through the release film 12, so that the functions of alignment and adhesion are realized. In the in-service use process, the lamp shade reflector plate 11 should guarantee to bear the weight of the type membrane 12 that has sticky tape 13 from type membrane 12 for the length that outwards extends from the first end in the type membrane 12, when guaranteeing to pull out this type membrane 12 simultaneously, has sufficient intensity, can prevent to stretch out or other bad situations take place.
Understandably, in an auxiliary device 10 for assembling a backlight module and a backlight module, an adhesive tape 13 is disposed on the surface of a lampshade reflecting sheet 11, and the lampshade reflecting sheet 11 is adhered to the inner side of an installation part 21 of a back plate 20 through a release film 12, so as to improve the brightness of the backlight and reduce the occurrence of obvious dark intervals at the incident light position of a light source 60. From type membrane 12 has very good roughness, play the effect of the installation of supplementary lamp shade reflector plate 11, under the very short condition of connecting portion 23 of backplate 20, the finger is difficult to stretch into in the 20 semi-enclosed spaces of backplate, through stretching into to semi-enclosed space from type membrane 12, counterpoint and paste more easily, with lamp shade reflector plate 11 installation back, strip from type membrane 12, the problem of the difficult attached and counterpoint of lamp shade reflector plate 11 has been solved, the loss rate of material has been reduced, the packaging efficiency of reflector plate 30 has been improved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
