Description
Technical field
The utility model relates to display field, particularly relates to backlight module, backboard and TV.
Background technology
LCD TV is that one provides uniform area source by backlight module, and this light carries out by liquid crystal display a kind of device showing various image.Existing backlight module has two schemes, and one is side-light backlight module, and its lamp bar is installed on module side, the area source required for us is obtained through a series of optics, its advantage is TV can be done thinner, and inferior position is that oversize is difficult to realize, and price is high.Another kind is down straight aphototropism mode set, the parallel plane being evenly arranged in area source of its lamp bar, and obtain the area source required for us through another series of optical device, its advantage is cheap, be more apt to do oversize TV, but thickness is slightly thick.Still doing oversize and Low-cost electric apparent time, often select down straight aphototropism mode set.
As shown in Figure 1, Fig. 1 is the structural representation of down straight aphototropism mode set in prior art, described backlight module comprises backboard 30, LED lamp bar 10, lamp bar substrate 20 and securing member 40, described securing member 40 is screw, LED lamp bar 10 comprises several single lamps 11, the parallel plane being evenly arranged in area source of LED lamp bar 10, that is LED lamp bar 10 will parallelly be installed on backboard 30, existing installation method all uses screw to pass lamp bar substrate 20 to be attached on backboard 30 by LED lamp bar 10, or use clip to be clamped on backboard 30 by LED lamp bar 10, above two kinds of mode principles are identical, therefore cause same problem.Single lamp 11 is arranged on can on the lamp bar substrate 20 of heat conduction, lamp bar substrate 20 shape is narrower strip, be installed on after on backboard 30 to make LED lamp bar 10, assembly structure is stablized, and single lamp need be avoided, the position locking screw can be fixed on the centre of two single lamps 11, namely make a call to a through hole in the centre of two single lamps 11 and lock screw.At the screw place of locking because be subject to the compressing of screw power F, there is elastic deformation in backboard 30 and lamp bar substrate 20, and wherein because of the reason of lamp bar substrate 20 material and shape, lamp bar substrate 20 deflection is relatively large.Place is being locked gradually away from screw, under the effect of thrust N, elastic deformation is recovered gradually between LED lamp bar 10 and backboard 30, in the transition process of F and N, to make between backboard 30 and lamp bar substrate 20 shape at an angle, away from screw place, the two gap is increasing.And lamp bar substrate 20 other end is by be that another symmetrical screw pins down with single lamp 11, what to there will be with single lamp 11 position be limit, near-sinusoidal bending, namely single lamp 11 position is backboard 30 and lamp bar substrate 20 gap maximum.Because this distortion gap is caused by elastic deformation, so gap extremely unstable, when TV horns blared, drive lamp bar substrate 20 to resonate, lamp bar substrate 20 collides backboard 30, produces noise.Beating place is stressed minimum place (i.e. single lamp place) in addition, pats vibrations and will reduce single lamp life-span, even directly damage.Lamp bar substrate 10 can not directly be fitted at single lamp 11 place backboard 30, and the high temperature that single lamp 11 produces is difficult to be directly delivered on metal backing 30 and dispels the heat, and makes the overheated reduction of single lamp 11 even directly burn lamp service life.Therefore, how improving LED lamp bar stress deformation after mounting, is a problem demanding prompt solution.
