Description of the Invention: [Technical Field] The present invention relates to a backlight module, and more particularly to a backlight module having a good grounding effect. [Prior Art] The rapid advancement of modern multimedia related products has benefited from the diversified and leaping technological evolution of semiconductor components and display devices. Conventional display devices, such as cathode ray tubes (CRTs), have been limited in their development in space utilization and energy consumption. Today's technology trends are light weight, thin thickness and low energy consumption. Therefore, flat panel displays with high display quality and conforming to the trend of technology demand, such as liquid crystal display, have become the corner of the display market. . Since the liquid crystal display is a non-self-illuminating type display, it is necessary to provide a sufficient light source for display purposes. Therefore, the liquid crystal display usually uses a backlight module as a source of its light source, and its function is to supply high brightness and distribution. A uniform light source. The backlight module is mainly assembled by components such as a light source, a lamp cover, a reflector, a light guide plate, a diffusion sheet, a brightness enhancement film, and an outer frame. At present, the mainstream of the light source used in the backlight module is a white light emitting diode and a cold cathode fluorescent tube. Among them, white light emitting diodes are used in smaller displays, such as mobile phones; cold cathode fluorescent tubes are used in larger flat display devices such as LCD TVs. As the demand for large displays continues to grow, as the display area increases, the brightness requirements of the light source also increase. However, since the current density of the lamp for supplying the light source is increased, the heat generation is likely to occur and the current leakage is increased, or the electrostatic effect is caused by the accumulation of the charge density, which damages the display panel. Therefore, when the backlight of the module 200807081 is assembled, the way of grounding is a step that cannot be ignored. The grounding method of the conventional backlight module lamp group is completed by screws or conductive aluminum foil. As shown in FIG. 1 , the grounding structure of the conventional backlight module includes the back plate 200, the lamp group 300, and the screw. 400 and conductive foil 402. The lamp tube assembly 300 is composed of a reflector cover 302 covering the lamp tube 304. The reflector cover 3〇2 is attached to the back plate 200 by using the screw 400, so that the reflection cover 302 and the back plate 200 are tightly coupled and grounded. Alternatively, the conductive foil 402 may be attached to the reflector 302 to be grounded, or the grounding effect may be enhanced to combine the two methods. However, regardless of the method selected above, it is necessary to increase the material cost of the screw 4 and the conductive label 402, as well as the additional labor cost and the risk of human error. SUMMARY OF THE INVENTION In order to solve the above problems, one of the objects of the present invention is to provide a group, the structure of the bent piece having a bent portion, which can ensure the assembly, after the assembly, can achieve the purpose of grounding. One of the purposes of the present invention is to provide a backlight module in which a shrapnel is formed on a backing plate or a light source cover by means of a gold forming body, by means of I-contacting the backing plate and the hood (four) m for charge _ the film power = one of the purposes of the present invention is to provide a backlight module, the use of the bomb type 3 instead of the screw lock and the conductive name box attached, can be two degrees, thereby improving the process yield and production efficiency. After the _i process, the purpose of the present invention is to provide a good grounding effect before providing a kind of backlight module assembly complexity. In order to achieve the above object, an anti-light source structure of an embodiment of the present invention is disposed on a backplane, wherein the light source structure includes: a cover and a 200807081 set in the cover a light-emitting member in the body; and a spring member disposed on the back plate and in contact with the cover of the light source structure, wherein the cover is electrically contacted with the back plate by the elastic member.

In the embodiment, the cover light-emitting member 44 can be used in the cold cathode county. In either of the lamp tube and the stepless fluorescent tube, the light-emitting member 44 is a light-emitting diode. When the light-emitting member 44 is a light-emitting diode, the cover U can provide a good light source without applying a reflective layer. Different from the above-mentioned embodiment, the elastic member 30 is disposed on the cover 42 of the light source structure 40 and is in contact with the back if the cover 42 is in contact with the elastic member 3G and the back plate 20. In this case, the elastic member 100 has a "bending portion" which is such that the cover 42 and the back plate 2G are in close contact with each other, for example, tightly fitting the t-mode to achieve good electrical contact. A charge discharge path for leakage current generated by the lamp source structure 40 is provided by the cover 42 being closely mated with the back plate 2'. In the second embodiment, the elastic member 3 is integrally formed with the cover 42, for example, when the cover 42 is formed. In order to make the grounding effect good, the elastic member 30 may not be placed on one side of the contact between the cover 42 and the back plate 2 . In the embodiment of the assembly of the moonlight module, this embodiment is the same as the previous embodiment. After the light source structure 40 and the backing plate 20 are assembled, for example, the bending portion 32 of the elastic member is engaged, and other components are assembled. The fine set is immediately available and there is no difficulty in assembly. According to the above, one of the features of the present invention is to use the bent portion of the elastic member to cause the light source structure to be in contact with the back plate. The bending 4 is tightly pressed to ensure that the light source structure has good electrical contact with the back plate. In addition, the light source structure can be fixed on the back plate to reduce the rupture of the backlight module and the swaying of the illuminating element. The situation happened. In addition, the shrapnel member can be set to 200807081 in the backplane or the light source structure - the illuminating element of the illuminating element that affects the light source structure = the position of the illuminating element can be set as long as it is not in the position of 1 9000, and the process is quite flexible. . In view of the above, the present invention provides a light mode M in which a bent portion of the elastic piece is used to ensure that the 'interference function is still present' after assembly to achieve grounding.
