The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model is done detailed description.
The backlight source module of the utility model display unit comprises backboard, and LGP is set in the backboard, adheres to blooming piece on the LGP, and light source is arranged on the LGP termination; The backboard scuncheon is provided with at least one fixture.Through fixture light source is fixed on the frame of backboard, replaces modes such as existing stickup.Light source mainly comprises lamp bar and fluorescent tube.In following preferred embodiment, light source is selected the lamp bar for use, and used lamp bar is the LED lamp bar that includes a plurality of light source blocks.
Preferred embodiment one: like Fig. 1～shown in Figure 4, the backboard 1 of the backlight source module of the utility model display unit is identical with existing back board structure, and fixture is the L-shaped baffle plate in cross section 2.The termination, bottom surface of baffle plate 2 is fixed on the backboard 1, baffle plate 2 and the backboard 1 common U-lag mouth 12 of forming fixed L ED lamp bar, and the spacing direction of notch 12 is as the criterion with the convenient LED lamp bar of installing.That the cross section that connects the frame of baffle plate 2 on the present embodiment dorsulum 1 can be is L shaped, can be 1 font, also can be other shapes, and its shape satisfies and firmly connects baffle plate 2 and can get final product with the requirement that baffle plate 2 is formed notches 12.Baffle plate 2 is between any two light source blocks on the LED lamp bar.
In order to make LED lamp bar install more stablely, on backboard 1 frame at baffle plate 2 places, at least one locating piece 3 is set.The spacing direction of locating piece 3 is vertical with the spacing direction of notch 12, and this structure can make LED lamp bar limited along backboard 1 frame direction.Position near locating piece 3 on the backboard 1 is provided with through hole 4, and through hole 4 is used to wear the interface element of LED lamp bar.
Preferred embodiment two: like Fig. 5～shown in Figure 7, the cross section of backboard frame is the L type, comprises orthogonal vertical edge 21 and base 22.Fixture is the 1 font baffle plate 2 that is fixed on the said base 22; 21 of baffle plate 2 and vertical edges form the notch 12 of fixed L ED lamp bar.Baffle plate 2 is between any two light source blocks on the LED lamp bar.
In order to make LED lamp bar install more stablely, be provided with and embodiment one essentially identical locating piece 3 in the present embodiment.Position near locating piece 3 on the backboard is provided with through hole 4, and through hole 4 is used to wear the interface element of LED lamp bar.
The mounting process of LED lamp bar is identical in the back board structure of preferred embodiment one and preferred embodiment two, and existing back board structure with preferred embodiment two serves as with reference to the use of describing the backlight source module of display unit.Like Fig. 8～shown in Figure 10, LED lamp bar 11 is placed between the locating piece 3 at vertical edge 21 two ends, make LED lamp bar 11 along vertical edge 21 inboard slippages downwards in being stuck in notch.Slightly push LED lamp bar 11, guarantee that LED lamp bar 11 fully contacts with the bottom surface of notch.Interface element 5 is passed the through hole of backboard frame, external drive unit.
