As for the back = =, there are many lamps and light guiding parts in the back money group. If the grounding is done, it is usually connected to the grounding ground by means of welding (4). However, during the welding process, air welding may occur. In the case of poor soldering, such as soldering, the lamp cannot be properly grounded, and the lamp cannot operate in one or two phases. Pre- or, if the solder joint is too large, when the backlight module is in Group I, it can be pressed to the solder joint itself or pulled to the wire connected to the solder joint, so that the tube cannot be properly grounded, resulting in improper charge. It is dangerous to accumulate. a Therefore, in order to improve the aforementioned shortcomings, it is necessary to modify the conventional flat panel display according to the structure and assembly process of the backlight module to avoid the trouble and danger that the soldering may not cause. SUMMARY OF THE INVENTION A technical aspect of the present invention provides a backlight module that uses a grounding member of a chip to electrically connect the conductive member to the ground of the backplane, thereby avoiding various problems caused by soldering. 201039023 According to one embodiment of the invention, a light source, a back plate, a conductive member disk; a ground; = a module comprising at least a negative electrode terminal connected to the light source. Grounding part 2:: 'The conductive part is electrically connected and the grounding part is electrically connected to the conductive part and the body'. Another aspect of the present invention provides a further embodiment of the present invention according to the present invention. With a backlight module. Wherein: the two flat-panel displays include the display, wherein the full-wheel ==贞==^#: the frame constitutes 'and the grounding member is electrically connected to the conductive portion: [Embodiment] In view of various problems that may be caused by welding, The following embodiments of the invention will ground the illumination source in a solderless connection. That is, the backlight module 〇 «the solder is not used to electrically connect the light source to the ground potential, but the light source is grounded by a sheet-like grounding member. Fig. 1 is a view showing an exploded view of a flat panel display according to an embodiment of the present invention. As shown, a flat panel display 100 includes a display module 110 and a backlight module 120. The backlight module 120 faces the display module Π0 ′ and the backlight module 120 includes a light source 122, a back plate 130, a conductive member 140, and a grounding member 150. The conductive member mo is electrically connected to the negative electrode terminal 123 of the light source 122. The grounding member 15 is formed of a sheet-like body, and the grounding member 150 is electrically connected to the conductive member 14A and the back plate 130. 4 201039023 The second figure shows the side view of the flat display of Fig. i, which is a side view of the portion of the group grounding member 15G. As shown, the present embodiment ground member 150 can have a fastening region 154 and an elastic region 152. Where = zone W is fixed to the back plate 13〇. The elastic zone 152 can be connected: 154 and resiliently contacts the conductive member 14Q. As such, the conductive member = and the back plate 13G will be electrically connected by the grounding material 15 () so that the negative electrode terminal of the light source is electrically connected to the ground potential (for example, the back plate 130).
具體而言，上述之彈性區152的材質可為彈性材 且此彈性區152在設計上可與導電部件14()些微過干涉， 使得彈性區152㈣確實抵住導電部件14()。以上述 些微過干涉制：導電部件14()與倾㈣之間的垂直距 離略小於彈性區152的高度，使得平面顯示器刚在組裝 後’彈性區152將略為受壓變形。 也就是說j本實施方式之接地部件15〇係採用彈性接 觸的方式接觸導電部件14G，因此接地部件15()與導電部 件140之間並不具有任何焊點，可確實避免因焊接所產生 的種種問題’例如：焊點不良或焊點體積過大導致背光模 組組裝困難。 彈性區I52的具體結構可依據不同的組裳需求作適當 的調整。以第2圖為例’彈性區152可具有彼此相對設置 之兩彈臂151。這些彈臂151的一端延伸連接於固接區 154,而另一端則接觸導電部件14〇。在平面顯示器i⑻的 組裝過程中，彈臂151將略為受到導電部件14〇的壓迫而 變形，以確保彈臂151能夠確實地電性接觸導電部件14〇。 5 201039023Specifically, the elastic region 152 may be made of an elastic material and the elastic region 152 may be designed to slightly interfere with the conductive member 14 such that the elastic region 152 (4) does resist the conductive member 14 (). With the above-described micro-interference system, the vertical distance between the conductive member 14() and the tilt (4) is slightly smaller than the height of the elastic region 152, so that the flat panel display will be slightly compressed after the assembly. That is to say, the grounding member 15 of the present embodiment contacts the conductive member 14G by elastic contact, so that there is no solder joint between the grounding member 15 () and the conductive member 140, and the welding result can be surely avoided. Various problems 'for example: poor solder joints or excessive solder joint volume make the backlight module difficult to assemble. The specific structure of the elastic zone I52 can be appropriately adjusted according to different group needs. Taking the second figure as an example, the elastic region 152 may have two elastic arms 151 disposed opposite to each other. One end of these elastic arms 151 is extended to be connected to the fastening region 154, and the other end is in contact with the conductive member 14A. During the assembly of the flat panel display i (8), the elastic arm 151 will be slightly deformed by the pressing of the conductive member 14 to ensure that the elastic arm 151 can surely electrically contact the conductive member 14A. 5 201039023
