The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the embodiment of the invention is further elaborated below in conjunction with Figure of description.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
Below the explanation of each embodiment be with reference to additional graphic, can be in order to illustration the present invention in order to the specific embodiment of implementing.The direction term that the present invention mentioned, for example " on ", D score, " preceding ", " front and back ", " right side ", " top ", " end ", " level ", " vertically " etc., only be direction with reference to the accompanying drawings.Therefore, the direction term of use is in order to explanation and understands the present invention, but not in order to restriction the present invention.
In following each embodiment, in different figure, identical or close part system represents with same numeral.
See also Fig. 1, Fig. 1 is the exploded view of the flat-panel screens 50 of one embodiment of the invention.Flat-panel screens 50 can comprise display floater 101, glue frame 102, framework 104, reflecting plate 106, LGP 108, optical diaphragm group 110 and 112 compositions of light source (as cold cathode ray tube).Optical diaphragm group 110 is set on the LGP 108, optical diaphragm group 110 can comprise diffusion barrier sheet, prismatic lens, blast sheet, combined optical film or its combination, and the effect of optical diaphragm group 110 is to revise radiation direction, the diffusion angle and raising brightness that light source 112 penetrates.One side of light source 112 can be coated with reflector 114, and reflector 114 is mainly the utilization rate that increases light.The light that light source 112 produces can penetrate display floater 101 after handling through elements such as reflecting plate 106, LGP 108 and optical diaphragm group 110, makes that the pixel on the display floater 101 produces different GTGs and produces image.It should be noted that, the invention is not restricted to this, also can be according to the actual demand adjustment, for example omit LGP and be applied to the backlight module of straight-down negative.
See also Fig. 2 and Fig. 3, Fig. 2 is the structure chart of framework 104, and Fig. 3 is the partial enlarged drawing of Fig. 2.Framework 104 can be the sheet metal component of metal material, and for example iron, aluminium, steel or other proper metal material or alloy are made.Framework 104 can roughly be a rectangle, is the edge that approximate vertical is positioned at bottom surface 1042 around the sidewall 1046 around the bottom surface 1042, and to form a disposal area 1047 (being shown in Fig. 6), elements such as reflecting plate and LGP can be placed in regular turn in disposal area 1047.The edge of the bottom surface 1042 of framework 104 is provided with a plurality of breach 1044, and these breach 1044 extend on the sidewall 1046 by bottom surface 1042, and promptly breach 1044 is across bottom surface 1042 and sidewall 1046.Sidewall 1046 is provided with a plurality of inner fovea parts 1048, and each inner fovea part 1048 it should be noted that corresponding to a breach 1044 inner fovea part 1048 is past disposal area, script position 1047 indents by sidewall 1046.In addition, framework 104 also is provided with a plurality of blocks 1045, and each block 1045 is approximately perpendicular to bottom surface 1042 and is arranged at corresponding to breach 1044 parts.In addition, framework 104 comprises at least one long limit and at least one minor face, because long limit is yielding compared to minor face, a plurality of breach 1044 can be arranged at least one long limit of framework 104, for the usefulness that snap-in structure is set, especially, glue frame 102 is firmly combined with framework 104 when the limit on long limit is thick when more carefully approaching.Only the invention is not restricted to this, also visual demand is provided with breach 1044 at minor face.
See also Fig. 4 and Fig. 5, Fig. 4 illustrates not combination preceding framework 104 and glue frame 102, and Fig. 5 is the partial enlarged drawing of Fig. 4.Glue frame 102 is the rectangular configuration of a central hollow out, its edge is provided with a plurality of holding sections 1022 and a plurality of groove 1024, each groove 1024 is corresponding to the inner fovea part 1048 on the sidewall 1046 of framework 104, and each holding section 1022 is the block 1045 corresponding to framework 104.Inner fovea part 1048 can roughly be the U font.On the projection plane that is parallel to bottom surface 1042, the periphery of sidewall 1046 to the distance of inner fovea part 1048 less than the periphery of sidewall 1046 distance to block 1045, in other words, leave a gap d (as shown in Figure 9) between inner fovea part 1048 and the block 1045.
See also Fig. 6 to Fig. 9, Fig. 6 is the framework 104 and glue frame 102 that illustrates after the combination, and Fig. 7 is the partial enlarged drawing of Fig. 6 towards the arrow E direction, and Fig. 8 is the partial enlarged drawing of Fig. 6 towards arrow F direction, and Fig. 9 is the profile of Fig. 6 along 6-6 ' hatching.Flat-panel screens 50 of the present invention is when assembling, the holding section 1022 of glue frame 102 breach 1044 corresponding to framework 104 is pressed into, make holding section 1022 insert the gap between inner fovea parts 1048 and the block 1045, that is to say, each holding section 1022 is suitable for wearing between the corresponding block 1045 and an inner fovea part 1048, makes block 1045 support holding section 1022.At this moment, as shown in Figure 7, each inner fovea part 1048 comprises a guide structure 1049, is suitable for guiding each inner fovea part 1048 to be directed to a groove 1024.One guide structure 1049 can be two hypotenuses that sidewall 1046 is connected with inner fovea part 1048.In addition, inner fovea part 1048 can be plane or inclined-plane, visual actual demand adjustment in the face of the side of groove 1024.The block that upwards is convexly equipped with 1045 of framework 104 can support glue frame 102 just, makes that glue frame 102 is difficult for breaking away from from framework 104, and then improves the inwardly problem of arch distortion of glue frame 11.In addition, the sidewall 1046 of framework 104 is coated on the periphery of glue frame 102, is out of shape so can protect glue frame 102 not to be subject to the external force extruding.
See also Fig. 1 and Figure 10, Figure 10 is after framework 104 makes up with glue frame 102, with the flat-panel screens profile after the assembling of elements such as reflecting plate 106, LGP 108, optical diaphragm group 110.After framework 104 and glue frame 102 make up, light source 112 can be inserted in one of framework 104 side end edge, coated with reflector 114 again, and reflector 114 can be fixed in the side end edge of framework 104.Afterwards, LGP 108 is inserted in the disposal area 1047 of framework 104, and make the peristome of LGP 108 embedding reflectors 114 make it that location is installed, then, in regular turn optical diaphragm group 110 is placed the top of LGP 108.At last display floater 101 is put into the top of optical diaphragm group 110, utilized glue frame 102 supplemental support display floaters 101, to finish the assembling of flat-panel screens 50.Above assembling mode only is for example, only the invention is not restricted to this, also can be according to the actual demand adjustment.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the invention; when can doing various changes and modification, so the present invention's protection domain attached claim person of defining after looking is as the criterion.
