Generally, the liquid crystal display module is composed of a liquid crystal display panel, a main printed circuit board and a backlight module, wherein the main printed circuit board is used for providing external power to the liquid crystal display panel and the backlight module, so that the backlight module A light source is generated to cause the liquid crystal display panel to display an image. In addition, the backlight module is generally composed of a sub-printed circuit board, a light emitting diode (LED), and a light guide plate, wherein the light emitting diode is disposed on the surface of the sub printed circuit board and adjacent to the light guide plate. At the light entrance, and the sub printed circuit board is soldered and assembled with the main printed circuit board to obtain an external power source to cause the light emitting diode to generate a light source. 1A is a rear perspective view of a conventional liquid crystal display module, and FIG. 1B is a top view of a sub-printed circuit board and a body of the liquid crystal display module of FIG. 1A. Referring to FIG. 1B, the conventional printed circuit board 120 of the 'Lu θ θ 1 X-one/night crystal display module 100 includes a connected light source portion 12 such as a bent portion η 仳 and a connecting portion 120 c. L shape, and a plurality of light emitting diodes are disposed in the light source portion 120a' and the sub printed circuit board 120 has two second pads 5 M342518 (Pad) 124, and the two second pads 124 are located at the connecting portion 12〇c And the positive and negative polarities are represented by A and K, respectively. The main printed circuit board 11 of the above liquid crystal display module 100 has a first pad (not shown) corresponding to the second pad 124, and the light source part 120a of the sub printed circuit board 120 is stuck in the main printed circuit. On the back side of the stack (in Fig. 1A, since the light source portion 120a is covered by the outer frame (not shown), the see-through state is indicated by a broken line). In addition, the conventional technique bends the bent portion 12〇b upward so that the connecting portion 120c is connected to the front surface of the main printed circuit board 11〇, and the second pad 124 and the first pad are soldered with solder paste. The connecting portion 120c is fixed to the surface of the main printed circuit board 11. The main printed circuit board can provide external power to the sub-printed circuit board 120 by the second pad 124, and the light-emitting diode 122 generates a light source, thereby passing the light source through the liquid crystal display panel (not labeled) ) to produce images. However, because the fcp connection is difficult to accurately grasp, the connection between the first pad and the second pad 124 is often poor. When the amount of the solder paste is too small, the main printed circuit board 110 and the sub-printed circuit board 12 are electrically connected in a poor condition, and even an open circuit occurs. When the amount of the solder paste is too large, the liquid crystal display panel 110 and the sub-printed circuit board 120 may be unevenly soldered, and even a short circuit may occur. In addition, the brushing and pressure welding process of welding the first pad and the second pad 124 is labor-intensive, and the manufacturing cost of the liquid crystal display module 1 is improved. In addition, when there is a problem in the main printed circuit board 110 or the sub-printed circuit board 12, the process of rework must be performed, and the first pad and the second pad 124 are first desoldered, and then the main printing is performed separately. The circuit board 11〇 and the sub 6 M342518 circuit board 12〇 are tested, so that the steps of the heavy work are complicated, and the knowledge is also quite time-consuming, thus greatly improving the difficulty and cost of the re-environment. The light source part 12〇& of the circuit board 12 is folded back and fixed to the surface of the main printed circuit board 11b, so when the liquid crystal display module is combined with other components (such as the outer casing of the mobile phone), the bend The protrusion of the folded portion 120b easily interferes with the structure of other members, thereby reducing the reliability and quality of the liquid crystal display module 100. [New content] In view of this, the purpose of this creation is to provide a liquid crystal display module, which has the characteristics of easy assembly and simple workmanship. In order to achieve the above or other purposes, the present invention proposes a liquid crystal display module 'including a liquid crystal display panel, a main printed circuit board, a backlight module, and at least an elastic conductive member.
