Embodiment
At first, show among the figure that LCD 20 has a display panel 30, one module backlight and a framework 50 with reference to Fig. 2.Wherein, display panel 30 is installed in the upper limb of framework 50, and module backlight then is installed in the framework 50.Therefore, only demonstrate the blooming lamella 40 that is positioned at module backlight the top among the figure.Framework 50 has one first glue frame 52 and one second glue frame 54.The first glue frame 52 is used for holding module backlight, and 54 tops that are arranged on the first glue frame 52 of the second glue frame are used for carrying display panel 30.
As shown in Figure 2, the second glue frame 54 is made of 542,544 of the side frames that can be separated from each other at least.With four side frames that can be separated from each other 542,544 in scheming is example.These four side frames 542,544 are four sides of corresponding display panel 30 respectively, are used for carrying display panel 30.Please refer to Fig. 3 A and Fig. 3 B simultaneously, side frame 542,544 has a groove 5422,5442 and at least one holding section 5424,5444 respectively.Wherein, groove 5422,5442 is used for holding display panel 30, and restriction display panel 30 vertical direction and horizontal direction is mobile.5424,5444 of holding sections are used for side frame 542,544 is incorporated into the first glue frame 52. Holding section 5424,5444 can be with the made button pawl structure of elastic material, then be manufactured with a corresponding fastening hole 522 on the first glue frame 52, utilize the elastic deformation of button pawl structure 5424,5444, just can and be fixed in the fastening hole 522 5424 assemblings of button pawl structure.
In addition, for the facility on assembling, has an extension 5426 corresponding to two side frames 542 of display panel 30 minor faces.Extension 5426 is extended with carrying display panel 30 towards the inside of the second glue frame 54 by the lower edge of groove 5422.As Fig. 4 and shown in Figure 5, in the assembling process of LCD, the side frame 542 that at first will have extension 5426 is placed on the first glue frame 52.At this moment, the holding section 5424 of side frame 542 also is not attached to the first glue frame 52 fully.In this case, the distance D 1 that this two side frame is 542 can be placed on the extension 5426 to guarantee display panel 30 smoothly greater than the width of display panel 30.Next, as shown in Figure 5, the holding section 5424 with this two side frame 542 is attached to the first glue frame 52 fully again.Like this, the distance D 2 that this two side frame is 542 just less than the width of display panel 30, is fixed in the groove 5422 to guarantee display panel 30 smoothly.Again two other side frame 544 is installed on the first glue frame 52 at last, with the long limit of fixed display panel 30.In fact, extension 5426 is made in the side frame 542 corresponding to display panel 30 relative two minor faces.But the utility model is not limited to this.Be used for carrying the extension of display panel 30, also can be made in corresponding to relative two of display panel 30 and grow on the side frame 544 on limits.
Fig. 6 is the synoptic diagram of another better embodiment of the utility model holding section.With respect to the holding section 5424,5444 of Fig. 3 A and Fig. 3 B, the front end of the button pawl structure 5424 ' of Fig. 6 has a guide posts R.The bearing of trend of this guide posts R is perpendicular to the trend of side frame 542, is attached to the first glue frame 52 to guide button pawl structure 5424 ' along the opening direction (i.e. the direction of arrow among the figure) of groove 5422.Certainly, side frame 544 has a button pawl structure 5444 ' (not shown) equally, and its structure as previously mentioned.Please refer to Fig. 4 and Fig. 5 simultaneously, if use the button pawl structure 5424 ', 5444 ' of present embodiment, in the number of assembling steps of Fig. 4, the user can insert fastening hole 522 with the guide posts R that is positioned at button pawl structure 5424 ', 5444 ' front end earlier, temporarily fixes 542 side frames on the first glue frame 52.Display panel 30 is positioned on the extension 5426 of side frame 542 then.As shown in Figure 5, will detain pawl structure 5424 ' at last again and insert fully in the fastening hole 522, to finish the assembling of LCD 20.
Fig. 7 is the synoptic diagram of the utility model first glue frame 52 1 better embodiment.As shown in the figure, the inner surface of the first glue frame 52 scribbles a reflection horizon 524, is used for reflecting the luminous of backlight (for example fluorescent tube or light emitting diode), improves the luminescence efficiency of module backlight.Reflection horizon 524 among the figure is the inner surfaces that are coated on the first glue frame, 52 1 sidewalls.But be not limited in this, reflection horizon 524 also can be coated on the inner surface of the first glue frame, 52 bottoms, decides with backlight the position being set.Secondly, the inner surface that in the present embodiment is coating reflection layer 524 first glue frames 52 also is not limited only to this certainly to improve luminescence efficiency.The also available separable reflecting plate in reflection horizon 524 replaces.This reflecting plate can utilize the mode of attaching or be installed in the inner surface of the first glue frame 52 in the engaging mode.
With reference to Fig. 8, as shown in the figure, framework 60 has one first glue frame 62 and one second glue frame 64.The second glue frame 64 is made of the matrix side frame 642 that both can be disconnected from each other.These two matrix side frames 642 are corresponding to the long relatively limit of display panels 30.Two barrier wall structures 622 are arranged, corresponding to the relative short edge of display panel 30 on the first glue frame 62.And each matrix side frame 642 all has a groove 6422 and at least one holding section 6424.Groove 6422 is used for holding display panel 30.6424 of holding sections are attached to matrix side frame 642 on the first glue frame 62.
Refer again to Fig. 9.As shown in the figure, framework 70 has one first glue frame 72 and one second glue frame 74.The second glue frame 74 by two can be disconnected from each other L type side frame 742 constituted.Each L type side frame 742 corresponds respectively to the adjacent dual-side of display panels 30.And each L type side frame 742 has a groove 7422 and at least one holding section 7424.Groove 7422 is used for holding display panel 30.7424 of holding sections are used for L type side frame 742 is attached to the first glue frame 72.
With respect to the LCD of Fig. 1, be difficult to effectively to control the spacing distance of 11 of display panel 12 and chases, then may cause the generation of repressive exposure.As shown in Figures 2 and 3, because LCD 20 of the present utility model is to utilize the groove 5422 clamping display panels 30 that are made in side frame 542, by the width of accurate control groove 5422, just can avoid the generation of repressive exposure, and can omit the use of the cushion 11a among Fig. 1.Secondly, side frame 542 of the present utility model has extension 5426 to carry display panel 30, and, holding section 5424 is arranged to be combined to the first glue frame 52 on the side frame 542.Therefore,, can earlier side frame 542 temporarily be fixed on the first glue frame 52 as Fig. 2 and shown in Figure 3, wait display panel 30 to be placed on extension 5426 after, again side frame 542 is fully assembled to the first glue frame 52.Adopt this assembling flow path, not only can avoid the possibility of display panel 30 fragmentations, and simplified the assembling difficulty.
Though the utility model has been enumerated embodiment preferably hereinbefore, be not to be used for limiting the utility model.Any technical field all has the hi-tech talent, in not breaking away from spirit and scope of the present utility model, also can do a little change and retouching.What claim was defined after therefore, protection domain of the present utility model should be looked attached is as the criterion.
