[specific embodiment]
See also Fig. 3 and Fig. 4, Fig. 3 is the schematic diagram of display 3 according to an embodiment of the invention, and Fig. 4 is the schematic diagram of backlight module 32 according to an embodiment of the invention.As shown in Figure 3 and Figure 4, display 3 comprises a housing 30, a backlight module 32 and a display floater 34.Backlight module 32 all is arranged in the housing 30 with display floater 34, and display floater 34 is arranged on the backlight module 32.In practical application, display 3 can be a LCD, and display floater 34 can be a display panels.In addition, the light emitting source of backlight module 32 can be cathode fluorescent tube or light emitting diode.It should be noted that the people that the action principle of backlight module 32 and display floater 34 can be existing skill reaches easily, does not repeat them here.
See also Fig. 5, Fig. 5 is the explosive view of the backlight module 32 among Fig. 4.As shown in Figure 5, backlight module 32 comprises a LGP 320 and framework combination 322, and wherein framework combination 322 comprises one first framework 3220 and one second framework 3222.In practical application, first framework 3220 can be a glue frame, and second framework 3222 can be a metal frame.
See also Fig. 6 to Fig. 8, Fig. 6 is the partial view of first framework 3220 among Fig. 5, and Fig. 7 is the partial view of second framework 3222 among Fig. 5, and Fig. 8 is the partial view of the backlight module 32 among Fig. 4.As shown in Figure 6, first framework 3220 has one first side wall 32200 and one second side wall 32202, and one first holes 32204 is formed on 32206 places, corner of first side wall 32200 and second side wall, 32202 adjacency.As shown in Figure 8, during assembling, LGP 320 is arranged in first framework 3220, and a corner 3200 of LGP 320 is revealed in first holes 32204.When LGP 320 was assembled to first framework 3220, first holes 32204 can avoid the corner 3200 of LGP 320 that fragmentation takes place.As previously mentioned, can be gapped between the corner 3200 of LGP 320 and first framework 3220 (gap 16 that illustrates as Fig. 1) exist.
As shown in Figure 7, second framework 3222 has one the 3rd side wall 32220, and one second holes 32222 and one the 3rd holes 32224 are respectively formed at two sides of the 3rd side wall 32220.In practical application, second framework 3222 can be the metal frame that utilizes sheet-metal forming.In the process of sheet-metal forming, the problem of material extrusions takes place for the 3rd side wall 32220 that prevents from being positioned at the corner, the present invention is that elder generation forms second holes 32222 and the 3rd holes 32224 respectively in two sides of the 3rd side wall 32220, again with the 3rd side wall 32220 bending formings.In the BENDING PROCESS of the 3rd side wall 32220, the material of the 3rd side wall 32220 just can spread toward second holes 32222 and the 3rd holes 32224 of two sides, and then avoids the problem of material extrusion to take place.In this embodiment, the depth D 1 of second holes 32222 can be designed to more than or equal to 1/2nd of the height H of the 3rd side wall 32220, and also the depth D 2 of the 3rd holes 32224 can be designed to more than or equal to 1/2nd of the height H of the 3rd side wall 32220, by this, can prevent effectively that the 3rd side wall 32220 from the problem of material extrusion taking place in the process of bending forming.
In this embodiment, curved and its two side of the 3rd side wall 32220 is extended towards two non-parallel direction A1, A2 respectively, direction A1, A2 folder an angle of 90 degrees wherein, as shown in Figure 7.In another embodiment, the 3rd side wall 32220 also can be rectangular metope.
As shown in Figure 8, when LGP 320 is arranged in second framework 3222 together with first framework 3220, the 3rd side wall 32220 can cover first holes 32204 fully from the outside of first framework 3220, that is the 3rd side wall 32220 can cover the corner 3200 of LGP 320 and the gap between first framework 3220 (can with reference to the gap 16 among the figure 1) fully, and the 3rd side wall 32220 can not contact with the corner 3200 of LGP 320.In addition, first side wall 32200 of first framework 3220 can cover second holes 32222 fully from the inboard of second framework 3222, and second side wall 32202 of first framework 3220 also can cover the 3rd holes 32224 fully from the inboard of second framework 3222.By this, can prevent effectively that the foreign matter of carrying secretly in the air from entering backlight module 32.
As shown in Figure 8, the width W of the 3rd side wall 32220 is determined by second holes 32222 that is formed on two sides and the 3rd holes 32224.In this embodiment, the width W of the 3rd side wall 32220 must be covered first holes 32204 on first framework 3220 fully, and the formation position of second holes 32222 and the 3rd holes 32224 must be able to prevent that the 3rd side wall 32220 from the problem of material extrusion taking place in the process of bending forming.Therefore, when LGP 320 is arranged in second framework 3222 together with first framework 3220, second holes 32222 and the 3rd holes 32224 are respectively adjacent to first holes 32204, by this, can make the 3rd side wall 32220 cover first holes 32204 on first framework 3220 fully, can prevent that the 3rd side wall 32220 from the problem of material extrusion taking place simultaneously in the process of bending forming.
In addition, it should be noted that, in practical application, the structural design in four corners of second framework 3222 all illustrate with Fig. 7 and corresponding explanation identical, do not repeat them here.
Compared to background technology, the present invention utilizes the 3rd side wall on second framework to cover first holes on first framework, enters backlight module to prevent foreign matter from first holes on first framework.In addition, form second holes and the 3rd holes respectively in two sides of the 3rd side wall, with in the process of sheet-metal forming, prevent the problem of the 3rd side wall generation material extrusion.In other words, in the process of sheet-metal forming, for the problem of the 3rd side wall generation material extrusion that prevents from being positioned at the corner, the present invention forms second holes and the 3rd holes respectively in two sides of the 3rd side wall earlier, again with the 3rd side wall bending forming.In the BENDING PROCESS of the 3rd side wall, the material of the 3rd side wall just can spread toward second holes and the 3rd holes of two sides, and then avoids the problem of material extrusion to take place.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
