In order to enable the reviewing committee to have a better understanding and approval of the structural purpose and efficacy of the present invention, the detailed description is as follows. [Embodiment] The technical means and efficacy of the present invention for achieving the object will be described below with reference to the accompanying drawings, and the embodiments listed in the following drawings are only for the purpose of explanation. The technical means are not limited to the illustrated figures. Referring to the second and third figures, the liquid crystal display device 20 of the present invention mainly includes a frame 21, a backlight module 22, a liquid crystal panel 23, a flexible printed circuit board 24, and a The bottom frame 25 is formed by a bottom plate 251, a first side plate 252 and a plurality of second side plates 253. The first side plate 252 and the plurality of second side plates 252 are disposed on the bottom plate. The 251 is edged, and an accommodating space is formed around the bottom plate 251.

The liquid crystal panel 23 is also disposed on the surface of the backlight module 22, and the liquid crystal panel 23 is composed of an upper polarizer 231, an upper glass substrate 232, and a lower glass substrate 233. And the lower polarizer 234 is formed by stacking up and down in sequence. The lower glass substrate 233 protrudes from the upper polarizer 231 and 201017272 to a certain length outside the glass substrate 232, and the glass substrate 233 is provided with a product under the protrusion. Body circuit 235; in addition, one end 241 of the flexible printed circuit board 24 The glass substrate 233 is connected to the liquid crystal panel 23 and electrically connected to the integrated circuit 235. The middle portion 242 of the flexible printed circuit board 24 is bent at one end of the frame 21 and the flexible printed circuit board 24 is reversed. One end of the folding end 243 is extended to the other side of the backlight module 22, that is, one surface of the reflective film sheet 221 is usually fixed by a tape (not shown) to avoid the softness. The printed circuit board 24 is reversely warped. In this embodiment, the flexible printed circuit board 24 is provided with a light-emitting element 244 on the side of the folded end 243. As shown in the figure, the bottom plate 251 of the bottom frame 25 is covered by the frame. The bottom surface of the chassis 21 is disposed on one side of the backlight module 22, and the first side plate 251 is located on the outer side of the frame 21 at the bend of the middle portion 242 of the flexible printed circuit board 24 at the top edge of the first side plate 251. There is a reverse flap 254. In this embodiment, the reverse flap 254 is a double-layered reverse flap.

The flexible printed circuit board can omit the tab 255. Referring to the fifth and sixth figures, the fifth figure shows an embodiment of the frame of the present invention. The frame 21 is a rectangular I-shaped frame formed by a plurality of sides 211 to 214, wherein the side 211 is Corresponding to one end of the glass substrate 233 extending from the protrusion 9 provided with the integrated circuit 235, the side 211 is provided with two platforms 215, and the platform 215 is extended by the side 211 toward the inside of the frame 21 by a certain length and The platform 215 is integrally formed with the side 211. When the liquid crystal panel 23 is disposed on the frame 21, as shown in FIG. 6, the bottom surface of the glass substrate 233 under the liquid crystal panel 23 can abut against the top of the platform 215. In this embodiment, the display can be simultaneously pressed and reinforced by the reverse flap 254 to prevent the lower glass substrate 233 or the integrated circuit 235 from directly impacting and reducing the energy generated by the impact, and the support of the platform 215 can be The lower glass substrate 233 is prevented from being broken due to vibration deformation or the line breakage of 7 201017272. Referring to the seventh embodiment, the embodiment is based on the embodiment of the sixth embodiment. The present embodiment is characterized in that the underlying glass substrate 233 is provided with a protective layer 236 covering the integrated circuit 235. The material of the layer 236 is not limited, and it is preferably a soft elastic material, such as silicone rubber, and the cover area of the protective layer 2 is not limited to 'but it is better to completely cover the underlying glass substrate 233'. The thickness of the protective layer 236 is less than or equal to the sum of the thicknesses of the upper polarizer 231 and the upper glass substrate 232, that is, the protective layer 236 has a coating height not higher than the surface of the upper polarizer 231, and is ^ The guiding layer 236 can completely cover the integrated circuit 235, so the thickness of the integrated circuit 235 is also less than or equal to the sum of the thicknesses of the upper polarizer 231 and the upper glass plate 232, so that even if not When the protective layer is coated for 2 megahertz, it is also avoided that the integrated circuit 235 is directly searched for because the height is too high; the seventh embodiment shows that the support of the platform 215 is supported by the pressing and reinforcing of the inverted flap 254. Role, and buffering of the protective layer 236 With, Lu may be provided beneath the integrated circuit is provided with a glass substrate 235 233, may have a height of impact resistance capability that protects the entire liquid crystal display device without fail by the force of impact. As described above, the structure of the liquid crystal display device of the present invention can surely improve the impact resistance of the integrated circuit of the liquid crystal display device. However, the above description is only an embodiment of the present invention, and the scope of the invention is not limited thereto. That is, the equal changes and modifications made by the applicant in accordance with the scope of the patent application of the present invention should still fall within the scope of the patent coverage of the present invention.
