[Prior Art] In recent years, liquid crystal displays (LCDs) have been widely used in electronic products due to their lightness, thinness, and low power consumption, such as laptop computers, digital cameras, and projectors. However, the liquid crystal display panel (LCDPanel) of the liquid crystal display device itself is not capable of emitting light, but the light source is provided by the backlight module (Backlight Module), and the liquid crystal display panel can display the image normally, so the backlight module has become a liquid crystal display device. One of the key components. At present, large-size liquid crystal displays, such as monitors, LCD TVs, etc., are still mainly based on Cold Cathode Fluorescent Lamps (CCFLs), because cold cathode fluorescent lamps have stable electrical and optical properties and long life. It has the advantages of shock resistance and impact resistance, so the cold cathode fluorescent lamp is the most suitable light source for the large-size backlight module. In the backlight module, a converter is usually used to convert a DC voltage signal into a high-frequency high-voltage pulse for illuminating the cold cathode fluorescent lamp in the backlight module to provide the brightness required for the liquid crystal display. In the conventional technology, the converter is disposed in a protective cover, and then the protective cover is mounted on the bottom surface of the back panel of the backlight module by screwing, thereby fixing the converter on the backlight module, and The converter is protected by a protective cover. However, there are many defects in fixing the protective cover by means of screw locking. For example, the screw locking method will result in inefficient production; and the large demand for screws will cause cost increase and inconvenient inventory management; There is a risk of the screws falling off and the whole mechanism is unstable. What's more, in the subsequent inspection process, if problems are found, it will inevitably require heavy work to be repaired and the protective cover needs to be opened. The screws will be repaired one by one. Caused a lot of inconvenience. Therefore, whether the fixing mechanism of the backlight module can safely bond the protective cover to the backboard and whether the assembly and disassembly between the protective cover and the backboard are facilitated will seriously affect the yield and the production speed. 5 201017261 • Therefore, it is necessary to provide a new fixing mechanism and a display device using the same to overcome the defects in the prior art.

Referring to FIG. 6A and FIG. 6B, in the second embodiment, a plurality of snap arms 2, φ 1 on the bottom surface 10, and each of the two latch arms 2 form a pair, and Forming - the right - the buckle # 2 _ _, in other words, each of the first and second surfaces 25' of the snap arm 2 are opposite each other and the second of the two buckles f 2' The straight surface %'s face each other. Therefore, each of the pair of latch arms 2 of the second embodiment is provided opposite to each other. As in the first embodiment, the second embodiment is also capable of easily attaching the protective cover 3 to the back panel 1 for the purpose of screwless locking. It should be noted that the present invention is not limited to the first embodiment and the second embodiment. It can be thought that the thorns can be set in the same direction, and each of the pair of snap arms can be set to be in the same direction, and #relatively not opposite, the same can be achieved. Each pair of latching arms does not have to be arranged in an axisymmetric manner with the backing plate «12 as the axis" as long as it is disposed on both sides of the backing plate space 12. The shape of the 〇 protective cover is not limited to the description in the above embodiment, and can be adjusted according to the shape of the converter. Please refer to the schematic diagram of the mine structure of the present invention. The display device 5 includes > back wire group 6 and - is installed on the county 6 panel, and the backlight module 6 is an age panel. 7 provided - back wire, backlight 6 includes a plurality of health pipes 6 〇, a reflector 6 - diffuser 62, - back plate 丨, - converter 4 and _ protective cover 3, wherein the converter 4 is protected by The cover 3 is fixed to the backboard, and the protective cover 3 is coupled to the backboard 1 by the fixing mechanism of the above-described first embodiment. The protective cover 3 can also be bonded to the backing plate 1 by the mechanism of the second embodiment described above or by other means. It is also necessary to say that _ is that the present invention is not limited to the _ change measurement on the backboard 11 201017261, and can also be used to fix other components. For example, a display panel often requires a circuit board as a driver to drive its display, and such a driver can also drive the circuit mechanism to be fixed to the backplane.
