The specific embodiment
Figure 1A illustrates the top view of the module backlight of the utility model one embodiment, and Figure 1B illustrates the profile of the module backlight of Figure 1A along I-I ' line, and Fig. 1 C illustrates the profile of the module backlight of Figure 1A along II-II ' line.Please also refer to Figure 1A, Figure 1B and Fig. 1 C, the module backlight 100 of present embodiment comprises that mainly a framework 110, is disposed at LGP 120, a plurality of luminescence component 130 and the support plate 140 in the framework 110.In the present embodiment, framework 110 has a first fixed structure 112 and an opening 114, and first fixed structure 112 and opening 114 for example are the two corresponding sides that are positioned at framework 110.In addition, LGP 120 has an incidence surface 122 and an exiting surface 124.Similarly, support plate 140 also is to be disposed in the framework 110, and these luminescence components 130 are to be disposed on the support plate 140.
In the present embodiment, because framework 110 is provided with opening 114 in side edge, therefore support plate 140 and setting a plurality of luminescence components 130 thereon can plug to framework 110 from opening 114, and make these luminescence components 130 be positioned at incidence surface 122 sides of LGP 120.The light that these luminescence components 130 are sent promptly is suitable for incidence surface 122 incidents by LGP 120, and by exiting surface 124 outgoing of LGP 120.Wherein, when support plate 140 plugged to framework 110, support plate 140 for example can contact with the electrical contact (not illustrating) in order to power supply to be provided in the module 100 backlight, so that luminescence component 130 can normal operation.
In addition, in the LGP 120 of present embodiment, a side of exiting surface 124 for example has a bottom surface 126 relatively, and incidence surface 122 promptly is to connect exiting surface 124 and bottom surface 126.Wherein, present embodiment can be provided with a reflecting plate 150 between bottom surface 126 and framework 110, goes into the outgoing effect with what strengthen light.Above-mentioned luminescence component 130 for example is light emitting diode or other suitable light emitting source, and support plate 140 for example is printed circuit board (PCB) or other suitable support plate.
Specifically, the support plate 140 one ends of present embodiment be provided with one with first fixed structure 112 corresponding second fixed structures 142, the other end be provided with one with the opening 114 corresponding structures 144 that cover.Wherein, second fixed structure 142 of support plate 140 is suitable for being sticked in the first fixed structure 112 of framework 110, but and the opening 114 that covers structure 144 cover framework 110 of support plate 140.Say that further the first fixed structure 112 of present embodiment for example is a draw-in groove, second fixed structure 142 for example is a trip.Therefore, in the time of in support plate 140 is inserted in framework 110 fully, second fixed structure 142 of support plate 140 can engage mutually with the first fixed structure 112 of framework 110.
On the other hand, cover covering structure 144 can prevent effectively that the light that luminescence component 130 is produced is incident upon outside the framework 110 outside opening 114 of opening 114.In addition, the shape of the opening 114 of present embodiment and size come down to and the shape of masking structure 144 and measure-alike, and masking structure 144 can be sticked in opening 114 by the mode of tight fit (connect tight1y).Thus, support plate 140 can be by the tight fit relation of 114 of the snap-fit relationship of 112 of second fixed structure 142 and first fixed structures and masking structure 144 and openings firmly to be fixed in the framework 110.Simultaneously, support plate 140 can be effectively contacts with the electrical contact (not illustrating) in order to power supply to be provided in the module 100 backlight, and then makes the luminescence component 130 can normal operations.Wherein, damage for some reason as luminescence component 130 and need keep in repair the time, the maintenance personal can extract whole support plate 140 by forcing in masking structure 144 in framework 110, to carry out maintenance activity.
In the present embodiment, masking structure 144 for example is to be a T type structure (shown in Fig. 1 C), and itself and support plate 140 can be used integrated mode and produce, and carries out the extraction operation of support plate and T type structure is the convenient for maintaining personnel.In addition, in other preferred embodiment, masking structure 144 also can be a Coupling (please refer to Fig. 2), and it can be placed in an end of support plate 140 adjacent openings 114.Wherein, the material of Coupling for example is rubber-like plastics or other suitable material, and Coupling can by its have can suitable elastically-deformable characteristic to tightly fit in effectively in the opening 114.Thus, maintenance personal's desire extracts support plate 140 when carrying out the maintenance activity of luminescence component 130, the maintenance personal only need push the rubber-like Coupling a little makes it produce deformation, can remove the tight fit state of Coupling and opening 114 easily, and then will in framework 110, take out with the support plate 140 that Coupling joins.
Please continue with reference to Figure 1B and Fig. 1 C, can more effectively be fixed in the framework 110 for making support plate 140, the module backlight 100 of present embodiment more comprises a locking part 160, and support plate 140 is provided with a locking hole 146.Thus, present embodiment can concern by the locking of 146 of locking part 160 and locking holes support plate 140 is fixed in framework 110.
Fig. 3 illustrates the schematic diagram of the LCD of the utility model one embodiment.Please refer to Fig. 3, the LCD 10 of present embodiment comprises a display panels 12, a housing 14 and above-mentioned module backlight 100.Wherein, display panels 12 is to be disposed on the framework 110 of module 100 backlight, and adjacent with LGP 120 its exiting surfaces 124 of module 100 backlight, and housing 14 then is that display panels 12 is fixed on the framework 110.
In sum, the utility model is that the two-phase respective side at its framework of module backlight is provided with a first fixed structure and an opening respectively, and support plate and a plurality of luminescence components of being provided with thereon can plug to framework versatilely from opening.Therefore, when luminescence component damaged for some reason, the maintenance personal need not time-consumingly to disassemble the housing and the module backlight of LCD again, and the support plate that can directly will be plugged in the framework from opening takes out, so that luminescence component is keeped in repair, increased the convenience in the maintenance.In other words, the utility model has preferable maintenance efficiency.
On the other hand, the utility model is except being provided with on the framework first fixed structure and the opening, also the end at support plate is provided with second fixed structure that is suitable for engaging with first fixed structure, is provided with one in the other end of support plate and has the beam projecting of preventing to framework and be suitable for and the friction tight structure that covers of opening.Therefore, support plate can firmly be disposed in the framework, and then can be effectively contacts with the electrical contact in order to power supply to be provided in the module backlight, and makes that luminescence component can normal operation.Certainly, concern by above-mentioned locking part and the locking between locking hole support plate is fixed in framework after, support plate can more firmly be disposed in the framework, and then support plate can more effectively with in order to the electrical contact that power supply is provided be contacted.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; have in the technical field under any and know the knowledgeable usually; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking claims person of defining.
