However, since the liquid crystal display panel itself has no illuminating characteristics, it is usually necessary to cooperate with a backlight source to achieve the display effect. As the size of liquid crystal display devices increases, the requirements for backlight module brightness are getting higher and higher. Since the direct type backlight module arranges the plurality of light sources in parallel to obtain a higher luminance, the application of the direct type backlight module is more and more common. Direct-type backlight modules usually use a Cold Cathode Fluorescent Lamp (CCLF), a Light Emitting Diode (φ LED) or a Hot Cathode Fluorescent Lamp (HCLF). light source. Among them, the hot cathode fluorescent lamp has been widely used in the direct type backlight module because of its high brightness, low power consumption and low heat generation.

The first lamp holder 13 and the second tube holder 14 are respectively disposed on the bottom plate 151 and adjacent to the opposite side walls 152, respectively. Each of the first lamp holders 13 corresponds to a second tube holder 14 to collectively hold a tube 12. The diffusion sheet n is disposed at the opening of the accommodating space. Referring to Fig. 2, a perspective view of the first lamp holder 13 shown in Fig. 1 is shown. The first lamp holder 13 includes a receiving hole 131. The second lamp holder 14 has the same structure as the first tube holder 13. The receiving hole 131 of each of the first lamp holders 13 is opposite to the corresponding receiving hole 13 1 of the second lamp holder 14 . Please refer to FIG. 3 , which is a perspective enlarged view of the lamp tube 12 shown in FIG. 1 . The lamp tube 12 includes a tubular body 12, a cylindrical anode electrode 122, a second cylindrical cathode electrode 123, and two filaments (not shown) disposed in the tube body. The two ends of the tube body 121 respectively correspond to the receiving holes 131 of the first lamp tube fixing seat 13 and the receiving holes 131 of the second lamp s fixing seat 14.

Then, the anode electrode 222 and the cathode electrode 223 at the other end of the bulb 22 are pressed into the two housing grooves 249 of the second bulb connector 25 in the same manner. Finally, the diffusion sheet 21 is placed at the opening of the accommodating space. So far, the assembly of the backlight module 2 is completed. After the backlight module 2 is assembled, the anode electrode 222 and the cathode electrode 223 are fixed to the first lamp connector 24 or the second lamp connector 25 by the two conductive elastic pieces 242 and the insulating spacer 240. The contact protrusion 243 abuts against the φ side curved surface 225.
