Embodiment
Please refer to Figure 1A, it illustrates the diagrammatic cross-section of display device of the present invention.Display device 100 comprises a display panel 110, one a preceding frame 120 and a backlight module 140.Display device 100 is a liquid crystal indicator in the present embodiment, and display panel 110 is a display panels, and light polarizing film 114 was attached at the upper surface and the lower surface of display panels respectively under last light polarizing film 112 reached.Backlight module 140 comprises a backboard 150, a location structure 160, an optical module 170, fluorescent tube 180 and assembly to be positioned.Assembly to be positioned comprises printed circuit board (PCB) (printed circuit board in the present embodiment, PCB) 190 and hide (shielding plate) 192, hide 192 and cover printed circuit board (PCB)s 190, and to be spirally connected or the mode of clamping is fixed on the back side 152 of backboard 150.Optical module 170 can be diffusion sheet, brightening piece, prismatic lens or diffuser plate, and printed circuit board (PCB) 190 can be a current converter (inverter).Backboard 150 has the back side 152 and front 154, and backboard 150 inserts and puts display panel 110 with preceding frame 120 and optical module 170, one reflector plates 156 are arranged on positive 154.Referring again to Figure 1B, it illustrates the partial enlarged drawing of the location structure of Figure 1A.One pilot hole, 158 passed through said front surface 154 and the back side 152.Please refer to Fig. 1 C, it illustrates first location division 162 of Figure 1A and the marriage relation of pilot hole 158.Location structure 160 has 162, the first location divisions 162, one first location division and passes pilot hole 158 by positive 154 and protrude from the back side 152.Because pilot hole 158 is made of a perforate 158a and a slit 158b, after backboard 150 is passed by perforate 158a in first location division 162, moves to the end of slit 158b and assembly to be positioned is sticked on the backboard.Except that shown in Fig. 1 C, can also there be various variation first location division 162 with the marriage relation of pilot hole 158.For example, first location division 162 can be the Fastening tenon structure of similar joint portion 166 among Figure 1A for example, but has long length H1.Wherein length H1 can cooperate the integral thickness of assembly to be positioned and adjust, to look the assembly to be positioned of actual needs engaging single or multiple lift.First location division 162 is formed by rubber-like materials such as for example plastics, and after pilot hole 158 was passed in 162 generations, the one temporary transient deformation of first location division, producing a recovery stress-healing was original shape; First location division 162 can also have for example identical shapes such as rectangle, ellipse, triangle or polygon with pilot hole 158, and first location division 162 is passed this pilot hole 158 and is protruded from this back side 152 by this front 154 after, again through 90 degree rotations or the shape that cooperates first location division 162 with other angle rotation and assembly to be positioned is sticked on the backboard.Shown in Figure 1B, assembly to be positioned comprises printed circuit board (PCB) 190 and hides 192 being positioned on the back side 152 with first location division 162.Shown in Figure 1A, location structure 160 also comprises one second location division 164 and support sector 165, the second location divisions 164 in order to locate fluorescent tube 180 on positive 154, and support sector 165 is in order to support optical module 170 on positive 154.Location structure 160 also comprises a joint portion 166, for example is a trip.Joint portion 166 is passed backboard 150 by positive 154 and is protruded from the back side 152, with in conjunction with location structure 160 and backboard 150.
In the present embodiment, first location division 162 is an after overhang, and printed circuit board (PCB) 190 and hide 192 between the after overhang and the back side 152 is in order to location printed circuit board (PCB) 190 overleaf on 152.Wherein hide 192 and also have a holes 194, the after overhang of part is protruded from by holes 194 and hides outside 192, after overhang can be located hide 192 overleaf on 152.
Yet the technical field under the present invention has knows the knowledgeable usually, the invention is not restricted to this as can be known.For example, do explanation, also can be used in the illuminated backlight module of side though the present invention is example with the direct type backlight module.Location structure 160 can be a plastic assembly, makes in the mode of ejection formation.And the location structure 160 of present embodiment also can omit joint portion 166, and by treat coupling unit as hide 192 with the related stationary positioned structure 160 of mode that is spirally connected or is fixed on backboard 150 on backboard 150.So can more strengthen the bond strength of location structure 160, avoid joint portion 166 to produce the problem of scraping bits simultaneously with backboard 150 interference.And location structure 160 does not need to avoid other assembly on the backboard 150 yet, can be more flexible on structural design.
In addition, please refer to Fig. 2, it illustrates the partial enlarged drawing of another kind of location structure of the present invention.The present invention also proposes a kind of location structure 260, first location division 262 of location structure 260 is a cantilever, assembly 290 to be positioned and to hide 192 be between the cantilever and the back side 152, cantilever pass backboard 150 and insert holes 194 with fixing hide 192 and assembly to be positioned 290 on the back side 152.But cantilever also can hide 192 edge and assembly to be positioned 290 on the back side 152 in order to insert and put.As long as therefore look the length H2 that actual needs is adjusted first location division 262, can finish different positioning functions.
The disclosed backlight module of the above embodiment of the present invention and use its display device has the bit architecture that resets more, can fix more than one assembly, comprises fluorescent tube, printed circuit board (PCB), covering or the like.The cost of producing different locating elements be can save, and assembling manpower and time saved.Because location structure adopts the plastics ejection formation, can realize the shape that location structure was difficult to realize of traditional sheet metal component processing, required for special positioning function.
In sum, though the present invention with a preferred embodiment openly as above, so it is not in order to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is as the criterion when looking claims person of defining.
