''.b, and the top surface of the wall 13 is provided with at least one second support buffering the second branch __ on the first branch _a and the engaging side wall 13 on the first and the first view, straight back 11 The size (height) is such that the upper surface of the Hr strips a, b can be boxed into a lion as the first plate-like element, for example - liquid crystal panel (not shown) the height of the diaphragm group 3 M 141 'to ensure light in the light Formed above the diaphragm group 3 and the first and second Wei strips a, b - an assembly space for the liquid crystal panel of the 3 12 1-361937 can be placed and the liquid crystal panel can be positioned by the surface i42 of the stepped side wall 14. The first and second support buffer strips a, b are made of a flexible or soft material or an elastically deformable material for buffering the liquid crystal panel supported on the first and second support buffer strips a, b , shock absorbers and protection. Examples of materials suitable for making the first and second floor buffer strips a, b include rubber. These support buffer strips a, b can be fixed to the top surface of the optical diaphragm group 3 and the engaging side wall 13 by any known technique, for example, a back layer can be added to the support buffer strips a, b. The glue is bonded to the top surface of the optical film set 3 and the engaging side wall i3. In addition, a surface of the stepped sidewall 14 is provided with a limiting buffer strip c for correspondingly contacting and abutting the liquid crystal panel as a lateral protection buffer for the liquid crystal panel. The limit buffer strip c is also made of a flexible or soft material or an elastically deformable material, such as rubber, and is fixed to the surface 142 of the stepped side wall 14 by a suitable means, for example, by providing a backing glue to be bonded thereto. On the surface 142. 1 Please refer to the partial combination view of the 7 ffl series (4)-real backlight module and a flat component (such as liquid crystal panel), wherein the flat component or liquid crystal panel is shown by a dotted line and is given by the number 5 Marked. As shown in the combination of the optical module and the flat component (liquid crystal panel) of the seventh embodiment, the liquid crystal panel 5 is placed on the optical film assembly 3 and the first and second support buffers during assembly. The assembly space defined above a and b is supported by the first and second support buffer strips a, b above the optical raft group 3. Then, the display module outer frame 6 is disposed outside the liquid crystal panel 5 to form a complete liquid crystal display module. Here, the liquid crystal panel 5 is assembled in the assembly of the optical film, and is jointly supported by the first branch and the second buffer (4) - the strip a and the second strip 3 = punch and protect She is able to prevent the liquid crystal panel 5 from being broken due to the pressing force of the assembly. In addition, the side of the liquid crystal panel 5 abuts against the limit buffer strip c, so the limit buffer strip c can prevent the side of the liquid crystal panel 5 from directly contacting the step side wall 14 from the M2 to avoid fragile liquid crystal panels and other hard materials. Surfaces, especially metal materials, are damaged by collision or vibration when in direct contact. Please refer to the hybridization pattern of the backlight module of the present embodiment shown in FIG. 8 - the crystal panel of the embodiment, and the peak of the invention is shown in the first embodiment of the present invention. The other--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The height of the strip & is preferably greater than the height of the optical film plate 3 such that the upper surface of the first support buffer strip a is higher than the filament group 3. At the same time, the position of the first-branch strip a is between the surface 142 of the stepped side wall 14 and the first optical film side 3a of the optical film group 3. Thereby, the weight of the liquid crystal panel 5 and the assembling force of the assembly can be prevented from being applied to the optical film group 3, but applied to the first step surface 143 of the more rigid stepped side wall 14. It is particularly worth mentioning that the assembly steps of the conventional liquid crystal display are generally assembled in the backlight module factory and then transported to another place for assembly with the liquid crystal panel. Therefore, an outer frame must be added outside the backlight module to facilitate the mounting and shipping of the backlight module. However, in the embodiment of the present invention, in addition to the implementation of the assembly steps described above, the assembly step can be performed at the same place, that is, the backlight module, the liquid crystal panel, and the display module frame are assembled at the same time. • A finished product not only saves the manufacturing and assembly costs of a frame outside the backlight module, but also raises the overall efficiency of the group. Therefore, the backlight module must be assembled with a liquid crystal panel in comparison with a conventional backlight module in which a base and an optical film (4) are further disposed. The embodiment of the present invention shown in the figure is supported by a first-order surface supported on the second-order side of the two opposite side edges of the base, the two-step sidewalls, and an optical film set, and an assembly space bearing-liquid crystal panel is formed. . Therefore, the back group does not need to additionally set a backlight module frame, and can be directly assembled with a liquid crystal panel, thereby effectively simplifying the structure of the backlight module. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the present invention has been disclosed in the above preferred embodiments. However, it is not intended to limit the invention, and the invention may be used in the spirit and scope of the invention. The change and retouching of the present invention, therefore, the protection of the present invention is subject to the patent specification.
