Fluorescent Lamp ’ CCFL)或是發光二極體(Light Emitting Diode，LED)來作 為背光源。在利用發光二極體作為背光源之平面顯示器中，最常見的作法 係將發光二極體焊接於一印刷電路板(printed Circuit Board , PCB)上，並且 利用螺絲將印刷電路板鎖固於背光模組之背框(backplate)上。由於印刷電路 板必須與背框緊密貼合，方能使發光二極體所發散之熱量順利傳導至背 框’以確保發光二極體不會發生過熱損壞的問題。 請參閱第1圖’第1圖係會示先前技術之薄型筆記型電腦的電路板12 組裝於背框14的組合圖。首紐薄型筆記型電腦使用的面板16與電路板 12(安裝用於驅動面板16的電路)送入組裝產線後，將電路板12與鐵件背框 14以螺絲18對準對應的螺孔2〇、22鎖住固定，藉以避免電路板12朝χ 方向γ方向及z方向的偏移。最後再用膠帶(丁ape)貼附於電路板12上以 保護兼m&f：路板I2。此種方式的優點是組裝容$，但缺點則是需要多鎖 附2顆以上的獅’不僅增加了製造成本，更秘了組裝卫時而降低了生 產效率’甚至在_多個螺猶，容紐生漏侧絲的現象。即使僅少量 201111870 的螺絲未鎖附至印刷電路板上，亦會使得印刷電路板無法平整地鎖固至背 框上。此外更難以確保每個螺絲鎖固至電路板上時，對於電路板施力之一 致性。如此造成了產品品質下降，導致良率降低。 因此，如何穩固且有效率地將印刷電路板平整地固定至背框上，實為 目前亟待研究之一重要課題。 【發明内容】 有鑑於此，本發明之目的係提供一種便於固定平面顯示器之電路板之 框架組以及應職框躲之顯示触，萌決先前技術的問題。Fluorescent Lamp ’ CCFL or Light Emitting Diode (LED) is used as a backlight. In a flat panel display using a light-emitting diode as a backlight, the most common method is to solder the LED to a printed circuit board (PCB) and lock the printed circuit board to the backlight with a screw. On the backplate of the module. Since the printed circuit board must be closely attached to the back frame, the heat radiated from the light-emitting diode can be smoothly conducted to the back frame to ensure that the light-emitting diode does not suffer from overheating damage. Referring to Fig. 1 'Fig. 1 is a combination view showing a circuit board 12 of a thin notebook computer of the prior art assembled to the back frame 14. After the panel 16 and the circuit board 12 (the circuit for driving the panel 16) used in the first notebook are fed into the assembly line, the board 12 and the iron back frame 14 are aligned with the screws 18 by the corresponding screw holes. 2〇, 22 are locked and fixed to avoid the offset of the circuit board 12 in the γ direction and the z direction. Finally, it is attached to the circuit board 12 with a tape (ding ape) to protect the m&f: road board I2. The advantage of this method is that the assembly capacity is $, but the disadvantage is that it requires more than 2 lions to lock more than not only increase the manufacturing cost, but also reduce the production efficiency when assembling the Guardian's time. The phenomenon of the leakage of the side wire. Even if only a small number of 201111870 screws are not attached to the printed circuit board, the printed circuit board cannot be flatly locked to the back frame. In addition, it is more difficult to ensure that each of the screws is biased to the board when it is locked to the board. This has caused a decline in product quality, resulting in a decrease in yield. Therefore, how to firmly and efficiently fix the printed circuit board to the back frame is an important issue to be studied. SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a frame group for facilitating the fixing of a circuit board of a flat panel display and a display of a job frame to hide the prior art.
