Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and a uniform distribution of light sources to enable normal display of images. Liquid crystal displays are now widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras and projectors. The demand for backlight modules and related components continues to grow. Referring to FIG. 1, the lamp tube 14 in the conventional backlight module 10 fixes the support base 13 to the back bezel 111. The support base 13 is a strip-like structure, and the support frame 12 is disposed at a certain interval. The longitudinal extension of the support base 13 is approximately perpendicular to the longitudinal extension of the bulb 14. Figure! A total of four support frames 12 are provided to support the fixing of four lamps 14. The support frame 12 is c-shaped for holding the lamps 14 around the clamp. The backing plate 11 is generally made of stainless steel or aluminum alloy, and the support frame 12 is mostly made of plastic: cow. Since the lamp tube 14 is of a hard structure, the size of the support frame may be variated due to manufacturing or long-term use, and thus the degree of adhesion between the lamp tube 14 and the support frame 12 may be affected to some extent. If the degree of tightness between the lamp tube and the 2 buds 12 is not good, it will easily cause different θ due to vibration, which will affect the user's feeling. The support seat 13 and the back plate are different objects or even different materials. 200937074, the production and material control are complicated, and relatively high production costs must be incurred. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a backlight module and a lamp support structure thereof, which are improved for the back plate.

In the preferred embodiment, as shown in FIG. 3, the width wi of the cushioning member 26 is larger than the width W2 of the ring arm 25 to stably support and hold the lamp tube 24; however, in practical applications, as long as the lamp can be stabilized That is, the present invention does not need to limit the width of the cushioning member 26 to be greater than the width of the ring arm. The cushion member % can be made of a soft material such as a rubber material, which can conform to the deformation of the branch frame 23 and the lamp tube ’ to make up for the variation of the size of each of the swing frames 23 due to the manufacture or use. In addition, the cushioning member 26 has a shock absorbing effect and can be effectively modified. It is a vibration phenomenon between the support frame 23 and the lamp tube 24 of the rigid object to avoid noise. In another embodiment, as shown in Fig. 3, the branch frame 23 can be formed by cutting the corresponding block from the bottom plate 22 and bending it. After the block is bent, it forms a block opening π 34 at the corresponding portion of the bottom plate. For example, first, the channel 3 3 is punched out at the corresponding position of the bottom plate ,, and the range covered by the sea channel 33 is equivalent to the corresponding block opening 34, and the hall contains the range, and the corresponding block is And punching out the corresponding tube for accommodating the lamp tube 24 to form a corresponding hole of the support frame 23. After that, the area of the support frame 23 will be punched out. The size of the support frame 200937074 23 due to the relationship of the cut channel 33 The block opening 34 is formed in the bottom plate 22 after the bending. Further, the support frame 23 can also be directly formed by the bottom plate 22 with respect to the other side of the lamp tube 24, that is, the channel 33 need not be cut out. FIG. 4 is a cross-sectional view taken along line 1-1 of FIG. 3. The c-shaped cushioning member is disposed on the support frame 23 and the lamp for exemplifying the same embodiment of the present invention. Between the tubes 24, the gap 31 between the ring arms 25 is slightly larger than the diameter of the tube 24, and the opening 32 of the buffer member 26 is smaller than the diameter of the tube 24. However, in practical applications, the tube can be stabilized. The present invention is not limited to the notch 31 between the ring arms 25 and the cushioning member 26 The size relationship of the port 32. Referring to Figure 5, the support post 27 can be fabricated in a similar manner in the backing plate 22, i.e., the support post 27 can also be stamped out of the bottom panel 22 and bent into a corresponding section. In this embodiment The support post 27 has a height greater than that of the support frame 23, and serves as a spacer for spacing the liquid crystal display panel from the space where the bulb 24 is disposed. ❹ The bottom plate 22 and the branch frame 23 of the present invention are integrally formed, that is, the support frame 23 By bending the corresponding block in the bottom plate 22, the cost of additionally manufacturing the support base and assembling the support base to the bottom plate can be omitted. In addition, the buffer member 26 can be added to effectively improve the support frame 23 and the light tube 24 The resulting vibrations, which in turn reduce the noise generated by the vibrations.
